How To Check Checkbox In jQuery

In this article we will show you the solution of how to check checkbox in jQuery, you may discover and choose HTML components with jQuery selectors based on their name, ID, class, etc type characteristics.

Every selector starts with a dollar sign and brackets: ().To locate an element by id, use the getElementById element selector.

Checkbox inputs have the boolean checked property. Using an id input and a button to activate a function to determine whether a checkbox was checked dynamically is possible.

The element is obtained by id utilizing the jQuery selector but by the isCheckedJQuery function within the code below.

That function returns true if an element exists, is really a checkbox, and also is checked; otherwise, it returns false.

To verify the status of checkboxes, use the jQuery:checked selector. Particularly created for radio buttons and checkboxes is the:checked selector.

To make that selection of both the element and indeed the event listener attached to these other elements that results in the checkbox being chosen simpler, we can utilize jQuery's selector syntax rather than pure JavaScript.

Step By Step Guide On How To Check Checkbox In jQuery :-

<html>
<head>
    <title>How to find all checked checkboxes in jQuery</title>

<body>
    <h2>Displaying all checked checkbox value in jQuery</h2>
    Read: <input type="checkbox" id="read" checked="checked" />

    Speak: <input type="checkbox" id="speak" />
    <div id="output"></div>
    <script src="http://code.jquery.com/jquery-1.6.2.min.js"></script>
    <script>
        $(document).ready(function () {
            $('input[type=checkbox]:checked').each(function () {
                var status = (this.checked ? $(this).val() : "");
                var id = $(this).attr("id");

  1. The first step is to write <HTML>, which tells the browser what version of HTML we're using. A tag is the first element of an HTML document.
  2. Use the <head> tag to describe the project's heading. In contrast to the final brackets, which are closed, the title and final brackets both are open.
  3. The <body> tag, which describes the webpage's body, is then placed after this. This is where the website's content is written.
  4. Then we create a checkbox for value reading, writing and speaking.
  5. The <script> tag was then added. The script tag also includes the javascript google API run or an explanation of the code or file we used.
  6. The script is then closed.
  7. Then we again opened the <script> tag and then added. The script tag also includes the javascript google API run or an explanation of the code or file we used.
  8. The script is then closed.
  9. After that we close program using </center></body></html>

Conclusion :-

A checkbox is utilized to show tiny squares that have a number of toggleable "on" and "off" options for the user.

If any of the options are chosen, a tick is shown; otherwise, that square box is left blank.

A form may contain a number of checkboxes, and each one functions separately from the others.

It is employed when a question with multiple correct answers is posed to a visitor.

I hope this article on how to check checkbox in jQuery helps you and the steps and method mentioned above are easy to follow and implement.
