I am using GWT to process a very old web site. This web site has a lot of
iframes. Each iframe has a relative url or '#' for its src. The compiled
javascript - *.nocache.js is included in top document head.
After a page is loaded, I click a link and the page generate following
iframe in ajax way.
<iframe src="mybottom?openform">
<html>
<body>
<div/>
<div/>
</body>
</html>
</iframe>
On OnLoad event, I have following code:
IFrameElement iframeElement; //I get an instance variable for above
iframe element
NodeList<Node> childNodes = iframeElement.getChildNodes();
int length = childNodes.getLength();
logger.info("childNodes length=" + length); //print out "childNodes
length=0"
final Document contentDocument = iframeElement.getContentDocument();
//Got UncaughtException: (SecurityError) : Blocked a frame with origin
"http://xxx.com"; from
//accessing a cross-origin frame.
I cannot understand why I got "cross-origin frame" issue because they are
same domain.
I do appreciate your help.
David
