How to check a checkbox is checked or not using jQuery

Use the jQuery prop() method & :checked selector

The following section describes how to track the status of checkboxes whether it is checked or not using the jQuery prop() method as well as the :checked selector.

<script>
    $(document).ready(function(){
        $('input[type="checkbox"]').click(function(){
            if($(this).prop("checked") == true){
                console.log("Checkbox is checked.");
            }
            else if($(this).prop("checked") == false){
                console.log("Checkbox is unchecked.");
            }
        });
    });
</script>

You can also use the jQuery :checked selector to check the status of checkboxes. The :checked selector specifically designed for radio button and checkboxes.

Let's take a look at the following example to understand how it basically works:

<script>
    $(document).ready(function(){
        $('input[type="checkbox"]').click(function(){
            if($(this).is(":checked")){
                console.log("Checkbox is checked.");
            }
            else if($(this).is(":not(:checked)")){
                console.log("Checkbox is unchecked.");
            }
        });
    });
</script>
