The onload function for a JSP embedded in an IFrame was causing the IFrame to expand and fill the entire browser

I am encountering an issue with an IFrame inside a DIV where the SRC attribute is being dynamically set by a JavaScript function. When the SRC is set to "file.jsp", an onload function within the file.jsp containing style adjustments was causing the IFrame to spread all over the webpage once it completed. Essentially, the iframe was covering the entire webpage. I need help in finding a solution to maintain the IFrame position after the onload function finishes.

The code within my onload function is as follows:

function load() {
    var url = window.location.href;
    if (url.indexOf('iip') > -1) {
        document.getElementById('peLibraryTreeDiv').style.width = "596px";
        parent.document.getElementById('privateEquityDiv').style.width =
                "96.9%";
        parent.document.getElementById('privateEquityDiv').style.top =
                "77px";
    }
}

Answer №1

This example is a valid and functional demonstration.

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <script>
        function changeIframe(newLocation){
            document.getElementById("myIframe").src=newLocation;
        }
        </script>
    </head>
    <body onload="changeIframe('http://www.example.com')">
        <div style="width:650px;float:auto;border:1px dotted #cccccc;">
            <iframe id="myIframe" src="http://www.ebay.co.uk/" width="100%" height=750px marginwidth=0 marginheight=0 hspace=0 vspace=0 frameborder=1 scrolling=auto>
              <p>Your browser does not support iframes.</p>
            </iframe>
        </div>
    </body>
</html>

It's worth mentioning that certain websites cannot be used as the source in an iframe, such as http://www.google.com. I have raised a query about this on SO at can't add google.com as src to an IFrame.
