Hi, I stuck with one requirement as describe in title and after searching for the solution, I found how can I call javascript function of the parent window whereas I am working with the child window. Here is the solution for you all.


Write below function of javascript in your parent window. We will call it later from the child.


    <script language=”javascript” type=”text/javascript”>

    function ParentWindowFunction()


        alert(‘Hi, At least someone has called me from the child window’);

        return false;




Write the below code in your child window


    <script language=”javascript” type=”text/javascript”>

    function CallParentWindowFunction()



        return false;




You can call above function from a button click event like

    <input type=”button”  name=”btn1″ value=”Call Parent Window Function” onclick=”javascript:return CallParentWindowFunction();”/>


That’s it. Now by clicking on this child window’s button you can call a function resides in parent window.

    parent.myfunction(); works fine when called from child iframe in IE and FF but it doesn’t work with safari.

    I have done this and I get an error: “window.opener” is null or not an object.

    The child is called from a IFrame of a Parent.

    Hi all,

    can you guys explain me what is working and what not..
    I have a javascript functions in Basepage.aspx so I inherits from child page
    “trying to call Parentwindowfunction from Basepage to child window which is a popup( another aspx acts a popup)”
    i get a null or invalid object. Can someone help me out of this..

      Not sure exactly what you mean by “inherit from child page”; but the parent page should never inherit from the child page. If that’s what you’re doing then you’re inheriting in the wrong direction. Think of it like this; that’s like you inheriting from your father; doesn’t work that way.

    I guess that it will work if the parent and child window are within same domain, otherwise the function call will be blocked because of cross domain scripting issues.

    But doesnt support in IE

    Completely solved my problem; I’d searched for hours and tried dozens of different methods with no luck. This article not only provided the answer; but it’s so simple I’m ashamed of myself for not thinking of it on my own.
