Working with checkboxes in jQuery allows developers to retrieve their checked status and associated values efficiently. When you have checkbox elements with unique IDs, fetching their checked status or values can be achieved through jQuery effortlessly.
Retrieving Checked Checkbox Value by ID in jQuery
1. HTML Checkbox Element
Start by setting up your HTML with checkboxes having unique IDs.

<input type="checkbox" id="checkbox2" value="value2"> Checkbox 2 <br>
<input type="checkbox" id="checkbox3" value="value3"> Checkbox 3 <br>
2. jQuery to Retrieve Checked Checkbox Value
Use jQuery to fetch the checked status or value of a checkbox by its ID.
// Retrieve the checked status by ID
$('#checkbox1').prop('checked'); // Returns true or false based on checked status
// Retrieve the value of the checked checkbox by ID
$('#checkbox2:checked').val(); // Returns the value of the checked checkbox or undefined if not checked
