JSONP :

JSONP means JSON with Padding.

JSONP does not use the XMLHttpRequest object.

JSONP uses the <script> tag instead.

Requesting an external script from another domain does not have this problem.

JSONP uses this advantage, and request files using the script tag instead of the XMLHttpRequest object.

Syntax:

<script src="demo_jsonp.php">

Server File :

 <?php 
$myJSON = '{ "name":"Prakash", "age":19, "city":"Allahabad" }';

echo "myFunc(".$myJSON.");";

?>

Callback Function:

function clickButton() { 
    var s = document.createElement("script");

    s.src = "jsonp_demo_db.php?callback=myDisplayFunction";

    document.body.appendChild(s);

}
