jQuery - serializeArray( ) Method



The serializeArray( ) method serializes all forms and form elements like the .serialize() method but returns a JSON data structure for you to work with.

The JSON structure returned is not a string. You must use a plugin or third-party library to "stringify".


Here is the simple syntax to use this method:

$.serializeArray( )


Here is the description of all the parameters used by this method:

  • NA


Assuming we have following PHP content in serialize.php file:

if( $_REQUEST["name"] )
   $name = $_REQUEST['name'];
   echo "Welcome ". $name;
   $age = $_REQUEST['age'];
   echo "<br />Your age : ". $age;
   $sex = $_REQUEST['sex'];
   echo "<br />Your gender : ". $sex;

Following is a simple example a simple showing the usage of this method:
