Today we are going to learn How to disable and enable the submit button depending on checkbox status.

To disable and enable buttons, use the prop() method in jQuery.

Submit button is disabled first, when the user  checks  it if he agrees with the condition.  Then the Submit button is enabled.

The jQuery code snippet below uses the class name 'agree'. It uses prop to set the attribute.

Code Example for enable disable submit button :


 index.php

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">

$(document).ready(function(){
 
$('form input[type="submit"]').prop("disabled", true); 
 
$(".agree").click(function(){
 
if($(this).prop("checked") == true){
 
    $('form input[type="submit"]').prop("disabled", false);
}
else if($(this).prop("checked") == false){
 
    $('form input[type="submit"]').prop("disabled", true);
} 
});
});

</script>
</head>
<body>
<div class="cotainer">
<div class="row">
<div class="col-md-4">
<form>
	<div class="form-group">
		<label>Name: <input type="text" class="form-control" name="username"></label>
	</div>     
	<div class="form-group">
