You have to be careful if you are accessing the iframe script from your parent page to ensure that your iframe has finished loading before requesting it. Here's an example:



window.onload = function () {
    document.getElementById('iframeId').onload = function () { //Attach an onload function to the iframe
        //Do the stuff you want to do with the iframe here
        //because this function is executed once the iframe has finished loading
    };
};

This is a small example I followed,

<title>Untitled Page</title>
<script type="text/javascript" >
    function ShowVal() {
        alert(myIframe.document.getElementById('nameText').value);
    }

</script>

'myIfrmae' is the id of the iframe. and 'nameText' is the textbox control on the page contained in the iframe.



I was calling this ShowVal function from the parent page with a single button click.

Thank.

PS Sorry, failed to post the whole example. Having problems publishing Html.
