Answer: 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.
Using the jQuery prop() Method
The jQuery prop() method provides a simple, effective, and reliable way to track down the current status of a checkbox. It works pretty well in all conditions because every checkbox has a checked property which specifies its checked or unchecked status.
Do not misunderstand it with the checked attribute. The checked attribute only define the initial state of a checkbox, and not the current state. Let's see how it works:
Example
Try this code »<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>Using the jQuery :checked Selector
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:
Example
Try this code »<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.");
}
});
});
