Call a parent window function from an iframe

Last Updated : 19 Jul, 2019

Did you ever want to call a code/website that belongs to the parent window, and that too from the child window? Well, some good news for new. You will be able to do your desired job. The window will get opened by using the iframe, and the communication could be done with the parent window from the child window.

To call a parent window function, use the following syntax and also refer to the code given below.
Syntax:

<a onclick="parent.abc();" href="#" > Call the parent window here </a>

Example :

<!DOCTYPE html> 
   
<html> 
   
<head> 
    <title>Calling a parent window function from an iframe</title> 
   
    <script type="text/javascript"
src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"> 
    </script> 
    <script type="text/javascript"> 
        $(function() { 
            $('[id*=iframe1]').load(function() { 
   
                //call here your javascript function 
                myfunction(); 
            }); 
        }); 
   
        function myfunction() { 
            alert('Function called after the IFrame load') 
        } 
    </script> 
   
</head> 
   
<body> 
   
    <center> 
        <h2 style="color:green">GeeksforGeeks</h2>
