serialize()

jQuery serialize() method is used to create a text string in standard URL-encoded notation. It is used in form controls like <input>, <textarea>, <select> etc. It serializes the form values so that its serialized values can be used in the URL query string while making an AJAX request.

Syntax:

snippet
$ (selector).serialize()

jQuery serialize() example

Let's take an example which serializes a form values.

snippet
<!DOCTYPE html>
<html>
<head>
  <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
<script>
$(document).ready(function(){
    $("button").click(function(){
        $("div").text($("form").serialize());
    });
});
</script>
</head>
<body>
<form action="">
  First name: <input type="text" name="FirstName" value="Sonoo"><br>
  Last name: <input type="text" name="LastName" value="Jaiswal"><br>
</form>
<button>Serialize form values</button>
<div></div>
</body>
</html>
Note
Note: Only successful controls are serialized to the string. It is not possible to serialize the form submitted by a submit button unless the form was submitted using a button.
