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:
$ (selector).serialize()
Let's take an example which serializes a form values.
<!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>
