JQUERY - INTERVIEW QUESTIONS AND ANSWERS

 

Q1: What is jQuery and why is it used in ASP.NET Core?

Answer: jQuery is a fast, lightweight, and feature-rich JavaScript library that simplifies HTML document traversal, event handling, animating, and Ajax interactions. In ASP.NET Core, jQuery is commonly used for:

  • Making AJAX calls to controllers

  • DOM manipulation and validation

  • Handling client-side events

  • Enhancing UI interactions

Example in ASP.NET Core:


$.ajax({
    type: "POST",
    url: "/Employees/Create",
    data: { name: "John", salary: 50000 },
    success: function(response) {
        $("#result").html("Employee added successfully");
    }
});

Q2: How do you include jQuery in an ASP.NET Core project?

Answer: There are multiple ways:

Option 1: Using CDN (most common)


<script src="https://code.jquery.com/jquery-3.6.0.min.js"></script>

Option 2: Using LibMan (Library Manager)


// libman.json
{
  "libraries": [
    {
      "library": "jquery@3.6.0",
      "destination": "wwwroot/lib/jquery"
    }
  ]
}

Option 3: Using npm/package.json


{
  "dependencies": {
    "jquery": "3.6.0"
  }
}

Q3: What is the difference between $(document).ready() and $(window).load()?

Answer:

$(document).ready()$(window).load()
Executes when DOM is ready (HTML loaded)Executes when entire page including images, CSS, scripts are loaded
Multiple instances can be usedOnly one instance
Faster executionSlower execution
Can be written as $(function(){})Must use full syntax

Example:

// Document Ready - Most common in ASP.NET Core
$(document).ready(function() {
    $("#btnSave").click(function() {
        // This works as soon as button exists
    });
});

// Window Load - For image-dependent operations
$(window).on('load', function() {
    $("#image").height(); // Image dimensions are now available
});

Q4: How do you make an AJAX call to an ASP.NET Core Controller?

Answer:

ASP.NET Core Controller:


[HttpPost]
public IActionResult GetEmployee(int id)
{
    var employee = _context.Employees.Find(id);
    return Json(employee);
}

jQuery AJAX call:


$.ajax({
    url: '/Employees/GetEmployee',
    type: 'GET',
    data: { id: 5 },
    dataType: 'json',
    success: function(data) {
        console.log(data.name);
        $('#name').val(data.name);
    },
    error: function(xhr, status, error) {
        alert('Error: ' + error);
    }
});

Q5: How do you handle Anti-Forgery Token in jQuery AJAX calls?

Answer:

In Razor View:

<form id="myForm">
    @Html.AntiForgeryToken()
    <!-- form fields -->
</form>

jQuery AJAX:

$("#btnSave").click(function() {
    var token = $('input[name="__RequestVerificationToken"]').val();
    
    $.ajax({
        type: "POST",
        url: "/Employees/Create",
        data: { Name: "John", Salary: 50000 },
        headers: {
            "RequestVerificationToken": token
        },
        success: function(response) {
            alert("Success");
        }
    });
});

Intermediate Level Questions

Q6: Explain event delegation in jQuery with an ASP.NET Core example

Answer: Event delegation allows you to attach events to elements that exist now or in the future. This is crucial in ASP.NET Core when dealing with dynamically loaded content.

Problem: Buttons loaded via AJAX don't have events attached

// This WON'T work for dynamically added buttons
$(".delete-btn").click(function() {
    // Not triggered for AJAX-loaded buttons
});

// This WILL work using event delegation
$(document).on("click", ".delete-btn", function() {
    var id = $(this).data("id");
    $.ajax({
        url: "/Employees/Delete/" + id,
        type: "POST",
        success: function() {
            $(this).closest("tr").remove();
        }
    });
});

Q7: How do you serialize form data in jQuery for ASP.NET Core?

Answer:

HTML Form:

<form id="employeeForm">
    <input type="text" name="Name" id="name" />
    <input type="number" name="Salary" id="salary" />
    <select name="DepartmentId" id="department">
        <option value="1">IT</option>
        <option value="2">HR</option>
    </select>
</form>

jQuery Serialization:

javascript
// Method 1: serialize() - creates query string
var formData = $("#employeeForm").serialize();
// Result: Name=John&Salary=50000&DepartmentId=1

// Method 2: serializeArray() - creates array of objects
var formArray = $("#employeeForm").serializeArray();
// Result: [{name: "Name", value: "John"}, ...]

// Method 3: Custom object (most used with ASP.NET Core)
var formObject = {};
$("#employeeForm").serializeArray().map(function(item) {
    formObject[item.name] = item.value;
});

$.ajax({
    url: "/Employees/Create",
    type: "POST",
    data: formObject, // ASP.NET Core binds this to your model
    success: function() { }
});

Q8: How do you implement client-side validation using jQuery in ASP.NET Core?

Answer:

HTML with validation spans:

<div class="form-group">
    <label>Name</label>
    <input type="text" id="name" class="form-control" />
    <span id="nameError" class="text-danger"></span>
</div>

jQuery Validation:

javascript
function validateForm() {
    var isValid = true;
    
    // Name validation
    var name = $("#name").val().trim();
    if (!name) {
        $("#nameError").text("Name is required");
        isValid = false;
    } else if (name.length < 2) {
        $("#nameError").text("Name must be at least 2 characters");
        isValid = false;
    } else {
        $("#nameError").text("");
    }
    
    // Email validation with regex
    var email = $("#email").val().trim();
    var emailPattern = /^[^\s@@]+@@[^\s@@]+\.[^\s@@]+$/;
    if (!emailPattern.test(email)) {
        $("#emailError").text("Invalid email format");
        isValid = false;
    }
    
    return isValid;
}

$("#btnSave").click(function(e) {
    e.preventDefault();
    if (validateForm()) {
        // Submit form
    }
});

Q9: Explain different jQuery AJAX methods and their use in ASP.NET Core

Answer:

// 1. $.ajax() - Most configurable
$.ajax({
    url: "/api/employees",
    type: "POST",
    data: JSON.stringify(employee),
    contentType: "application/json",
    dataType: "json",
    beforeSend: function() {
        $("#loader").show();
    },
    complete: function() {
        $("#loader").hide();
    },
    success: function(data) {
        console.log(data);
    },
    error: function(xhr) {
        console.log(xhr.status);
    }
});

// 2. $.get() - Simplified GET request
$.get("/Employees/Details/5", function(data) {
    $("#details").html(data);
});

// 3. $.post() - Simplified POST request
$.post("/Employees/Create", { name: "John" }, function(response) {
    alert("Created");
});

// 4. $.getJSON() - For JSON responses
$.getJSON("/api/employees", function(data) {
    $.each(data, function(i, emp) {
        $("#empList").append("<li>" + emp.name + "</li>");
    });
});

// 5. $.load() - Load HTML directly
$("#container").load("/Employees/PartialView/5");

Q10: How do you chain promises in jQuery AJAX for dependent calls?

Answer:

// Scenario: Get department, then get employees in that department
$.ajax({
    url: "/Departments/Get/5",
    type: "GET"
}).then(function(department) {
    // First AJAX complete
    console.log("Department: " + department.name);
    
    // Return second AJAX call
    return $.ajax({
        url: "/Employees/ByDepartment/" + department.id,
        type: "GET"
    });
}).then(function(employees) {
    // Second AJAX complete
    console.log("Found " + employees.length + " employees");
    
    // Process employees
    $.each(employees, function(i, emp) {
        $("#empTable").append("<tr><td>" + emp.name + "</td></tr>");
    });
}).fail(function(error) {
    // Handle any error in the chain
    console.error("Error in chain: ", error);
});

Q11: How do you implement cascading dropdowns using jQuery in ASP.NET Core?

Answer:

HTML:

<select id="country" class="form-control">
    <option value="">Select Country</option>
</select>

<select id="city" class="form-control" disabled>
    <option value="">Select City</option>
</select>

jQuery Implementation:

javascript
$(document).ready(function() {
    // Load Countries
    $.getJSON("/Location/GetCountries", function(countries) {
        $.each(countries, function(i, country) {
            $("#country").append($('<option>', {
                value: country.id,
                text: country.name
            }));
        });
    });
    
    // Country change event
    $("#country").change(function() {
        var countryId = $(this).val();
        
        if (countryId) {
            $("#city").prop("disabled", false);
            
            // Load Cities for selected country
            $.getJSON("/Location/GetCities", { countryId: countryId }, function(cities) {
                $("#city").empty().append('<option value="">Select City</option>');
                
                $.each(cities, function(i, city) {
                    $("#city").append($('<option>', {
                        value: city.id,
                        text: city.name
                    }));
                });
            });
        } else {
            $("#city").prop("disabled", true).empty()
                .append('<option value="">Select City</option>');
        }
    });
});

Q12: How do you implement infinite scrolling with jQuery in ASP.NET Core?

Answer:

Controller:

public IActionResult GetEmployees(int page = 1, int pageSize = 10)
{
    var employees = _context.Employees
        .Skip((page - 1) * pageSize)
        .Take(pageSize)
        .ToList();
    
    return Json(employees);
}

jQuery Implementation:

javascript
var page = 1;
var isLoading = false;
var hasMore = true;

$(window).scroll(function() {
    if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
        if (!isLoading && hasMore) {
            loadMoreEmployees();
        }
    }
});

function loadMoreEmployees() {
    isLoading = true;
    $("#loader").show();
    
    $.getJSON("/Employees/GetEmployees", { page: page, pageSize: 10 }, function(data) {
        if (data.length === 0) {
            hasMore = false;
            $("#noMoreData").show();
        } else {
            $.each(data, function(i, emp) {
                $("#empList").append(
                    '<div class="employee-item">' +
                    '<h4>' + emp.name + '</h4>' +
                    '<p>' + emp.designation + '</p>' +
                    '</div>'
                );
            });
            
            page++;
        }
        
        isLoading = false;
        $("#loader").hide();
    });
}

Q13: How do you implement real-time search/filter using jQuery?

Answer:

HTML:

<input type="text" id="searchInput" placeholder="Search employees..." />
<table id="employeeTable">
    <thead>
        <tr>
            <th>Name</th>
            <th>Designation</th>
            <th>Department</th>
        </tr>
    </thead>
    <tbody id="tableBody">
        <!-- Data loaded via AJAX -->
    </tbody>
</table>

jQuery Implementation with Debouncing:

var searchTimeout;

// Debounce function to prevent too many AJAX calls
$("#searchInput").on("keyup", function() {
    clearTimeout(searchTimeout);
    
    var searchTerm = $(this).val();
    
    searchTimeout = setTimeout(function() {
        if (searchTerm.length >= 2 || searchTerm.length === 0) {
            performSearch(searchTerm);
        }
    }, 500); // Wait 500ms after user stops typing
});

function performSearch(searchTerm) {
    $("#loader").show();
    
    $.ajax({
        url: "/Employees/Search",
        type: "GET",
        data: { term: searchTerm },
        success: function(employees) {
            var tbody = $("#tableBody");
            tbody.empty();
            
            if (employees.length === 0) {
                tbody.append('<tr><td colspan="3">No employees found</td></tr>');
            } else {
                $.each(employees, function(i, emp) {
                    tbody.append(
                        '<tr>' +
                        '<td>' + emp.name + '</td>' +
                        '<td>' + emp.designation + '</td>' +
                        '<td>' + emp.department + '</td>' +
                        '</tr>'
                    );
                });
            }
        },
        complete: function() {
            $("#loader").hide();
        }
    });
}

        type: "POST",
        data: formData,
        contentType: false,
        processData: false,
        xhr: function() {
            var xhr = new window.XMLHttpRequest();
            
            // Upload progress
            xhr.upload.addEventListener("progress", function(evt) {
                if (evt.lengthComputable) {
                    var percentComplete = Math.round((evt.loaded / evt.total) * 100);
                    $("#progressBar").css("width", percentComplete + "%")
                                     .text(percentComplete + "%");
                }
            }, false);
            
            return xhr;
        },
        success: function(response) {
            alert("File uploaded successfully");
            setTimeout(function() {
                $(".progress").hide();
                $("#progressBar").css("width", "0%").text("0%");
            }, 2000);
        },
        error: function() {
            alert("Upload failed");
            $(".progress").hide();
        }
    });
});

Q16: What are jQuery Deferred objects and how are they used?

Answer:

// Custom Deferred object
function validateAndSave() {
    var deferred = $.Deferred();
    
    // Validate first
    if ($("#name").val().trim() === "") {
        deferred.reject("Name is required");
    } else {
        // Save data
        $.ajax({
            url: "/Employees/Save",
            type: "POST",
            data: { name: $("#name").val() },
            success: function(response) {
                deferred.resolve(response);
            },
            error: function() {
                deferred.reject("Save failed");
            }
        });
    }
    
    return deferred.promise();
}

// Usage
validateAndSave().done(function(response) {
    alert("Success: " + response);
}).fail(function(error) {
    alert("Error: " + error);
});

// Multiple parallel AJAX calls
$.when(
    $.ajax("/Employees/GetAll"),
    $.ajax("/Departments/GetAll"),
    $.ajax("/Projects/GetAll")
).then(function(employees, departments, projects) {
    // All three calls completed
    console.log("Employees:", employees[0]);
    console.log("Departments:", departments[0]);
    console.log("Projects:", projects[0]);
}).fail(function() {
    console.log("One of the calls failed");
});

Q17: How do you optimize jQuery performance in ASP.NET Core applications?

Answer:

// 1. Cache jQuery selectors
// BAD
$("#name").val("John");
$("#name").addClass("valid");
$("#name").css("color", "green");

// GOOD
var $name = $("#name");
$name.val("John");
$name.addClass("valid");
$name.css("color", "green");

// 2. Use find() instead of context selectors
// BAD
$("#employeeTable .employee-row .employee-name");

// GOOD
$("#employeeTable").find(".employee-row").find(".employee-name");

// 3. Chain methods
// BAD
$("#name").addClass("valid");
$("#name").val("John");
$("#name").css("color", "green");

// GOOD
$("#name").addClass("valid").val("John").css("color", "green");

// 4. Use specific selectors
// BAD
$("div[data-id='5']");

// GOOD (if possible)
$("#employee-5");

// 5. Detach elements before multiple manipulations
var $table = $("#employeeTable");
var $tbody = $table.find("tbody").detach();

for (var i = 0; i < 100; i++) {
    $tbody.append("<tr><td>Row " + i + "</td></tr>");
}

$table.append($tbody);

// 6. Use event delegation for dynamic elements
// BAD
$(".delete-btn").click(function() { });

// GOOD
$(document).on("click", ".delete-btn", function() { });

// 7. Throttle/Debounce expensive operations
var resizeTimer;
$(window).on("resize", function() {
    clearTimeout(resizeTimer);
    resizeTimer = setTimeout(function() {
        // Expensive resize operation
        console.log("Resize complete");
    }, 250);
});

Q18: How do you handle AJAX errors globally in jQuery?

Answer:

// Global AJAX error handler
$(document).ajaxError(function(event, jqxhr, settings, thrownError) {
    console.log("AJAX Error:", thrownError);
    
    var status = jqxhr.status;
    var response = jqxhr.responseJSON;
    
    switch(status) {
        case 400:
            showNotification("Bad request: " + response.message, "error");
            break;
            
        case 401:
            showNotification("Your session has expired. Please login again.", "warning");
            setTimeout(function() {
                window.location.href = "/Account/Login";
            }, 2000);
            break;
            
        case 403:
            showNotification("You don't have permission to perform this action.", "error");
            break;
            
        case 404:
            showNotification("Resource not found.", "error");
            break;
            
        case 500:
            showNotification("Server error. Please try again later.", "error");
            break;
            
        default:
            showNotification("An error occurred: " + thrownError, "error");
    }
});

// Global AJAX start/complete handlers
$(document).ajaxStart(function() {
    $("#globalLoader").show();
});

$(document).ajaxComplete(function() {
    $("#globalLoader").hide();
});

// Custom notification function
function showNotification(message, type) {
    var notification = $('<div class="notification ' + type + '">' + message + '</div>');
    $("body").append(notification);
    
    setTimeout(function() {
        notification.fadeOut(function() {
            $(this).remove();
        });
    }, 3000);
}

Q19: How do you implement a jQuery plugin in ASP.NET Core?

Answer:

Creating a custom jQuery plugin:

// Custom validation plugin
(function($) {
    $.fn.validateEmployee = function(options) {
        var settings = $.extend({
            nameRequired: true,
            salaryRequired: true,
            minSalary: 0,
            onError: function() { }
        }, options);
        
        return this.each(function() {
            var $form = $(this);
            var isValid = true;
            
            // Name validation
            if (settings.nameRequired) {
                var $name = $form.find("#name");
                if ($name.val().trim() === "") {
                    $name.addClass("input-error");
                    $form.find("#nameError").text("Name is required");
                    isValid = false;
                } else {
                    $name.removeClass("input-error");
                }
            }
            
            // Salary validation
            if (settings.salaryRequired) {
                var $salary = $form.find("#salary");
                var salaryVal = parseFloat($salary.val());
                
                if (isNaN(salaryVal) || salaryVal < settings.minSalary) {
                    $salary.addClass("input-error");
                    $form.find("#salaryError").text("Invalid salary");
                    isValid = false;
                } else {
                    $salary.removeClass("input-error");
                }
            }
            
            if (!isValid && settings.onError) {
                settings.onError.call(this);
            }
            
            return isValid;
        });
    };
}(jQuery));

// Usage in ASP.NET Core view
$(document).ready(function() {
    $("#btnSave").click(function(e) {
        e.preventDefault();
        
        var isValid = $("#employeeForm").validateEmployee({
            nameRequired: true,
            salaryRequired: true,
            minSalary: 10000,
            onError: function() {
                $("#errorSummary").show();
            }
        });
        
        if (isValid) {
            // Submit form
            $("#employeeForm").submit();
        }
    });
});

Q20: How do you handle complex nested JSON data in jQuery?

Answer:

ASP.NET Core returns nested JSON:

public class EmployeeWithDetails
{
    public int Id { get; set; }
    public string Name { get; set; }
    public Department Department { get; set; }
    public List<Project> Projects { get; set; }
    public Dictionary<string, object> Metadata { get; set; }
}

// Controller returns complex object
return Json(employeeWithDetails);

jQuery handling:

$.ajax({
    url: "/Employees/GetWithDetails/5",
    type: "GET",
    dataType: "json",
    success: function(data) {
        // Access nested properties
        console.log("Employee:", data.name);
        console.log("Department:", data.department.name);
        
        // Loop through projects array
        $.each(data.projects, function(i, project) {
            $("#projects").append(
                '<li>' + project.name + ' (' + project.status + ')</li>'
            );
        });
        
        // Access dictionary/metadata
        $.each(data.metadata, function(key, value) {
            console.log(key + ": " + value);
        });
        
        // Build complex HTML
        var html = '<div class="employee-card">' +
                   '<h3>' + data.name + '</h3>' +
                   '<p>Department: ' + data.department.name + '</p>' +
                   '<h4>Projects:</h4>' +
                   '<ul>';
        
        $.each(data.projects, function(i, project) {
            html += '<li class="project-' + project.status.toLowerCase() + '">' +
                    project.name + ' - ' + project.status + '</li>';
        });
        
        html += '</ul></div>';
        
        $("#employeeDetails").html(html);
    }
});

Interview Tips: Dot NET Framework vs Net CORE .NET Framework What :  It's a software development framework created by Microsoft, mainly used for building Windows applications. Why :  It has been around for a long time and is very reliable for building large, complex applications especially for enterprises. How :  You use it to build applications that run exclusively on Windows, making use of a vast array of built-in libraries and features. Why Not :  It can't be used for cross-platform applications, so if you need your application to run on other operating systems like macOS or Linux, .NET Framework isn't the right choice. .NET Core What :  It's a newer, open-source, and cross-platform framework from Microsoft, designed for modern app development. Why :  It's lightweight, high-performance, and can run on multiple operating systems (Windows, macOS, Linux). How :  You use it to build modern, scalable, and quickly deployable applications, especially cloud...

OOP Concept in real-time scenario: Mobile Device Management Software

  Scenario: Mobile Device Management Software Context : You are developing a Device Management System for mobile providers like Realme, Redmi, Samsung, and Nokia. The system tracks and manages mobile devices, their specifications, and behaviors (e.g., sending notifications, updating software, logging activities). The software must handle different device types (e.g., smartphones, feature phones) with shared and unique features, ensure secure data handling, and support extensible functionality. Real-Time Relevance : Mobile providers need software to manage device configurations, push updates, monitor performance, and log activities for diagnostics. OOP concepts like encapsulation ensure secure data access, inheritance and polymorphism enable flexible device-specific behaviors, abstraction simplifies complex operations, and interfaces enforce consistent functionality across devices. This scenario aligns with tasks at companies like Equifax (data processing) or mobile software firms,...
