I have developed an application that has a list of items in one frame; when one clicks on an item it does something in another frame (loads an image).
This used to work fine in all browsers, including
Chrome 3; now it still works fine in Firefox but in recent versions of
Chrome (I believe since 4) it throws this error:
Unsafe JavaScript attempt to access frame with URL (...) from frame with URL (...).
Domains, protocols and ports must match.
This is obviously a security "feature" but is it possible to get around it?
Here is a simple test:
index.html:
<html>
<frameset cols="50%,50%">
<frame src="left.html" name="left"/>
<frame src="right.html" name="right"/>
</frameset>
</html>
left.html:
<html>
<body>
<a href="javascript:parent.right.test('hello');">click me</a>
</body>
</html>
right.html:
<html>
<body>
<script>
function test(msg) {
alert(msg);
}
</script>
</body>
</html>
The above works in Firefox 3.6 and
Chrome 3 but in
Chrome 5 it throws the above error...
Edit:
added the @cols attribute to the frameset element
in fact it works in
Chrome if and only if the pages are served with the http protocol (and from the same domain) but my problem is when pages are local and served from a file:// protocol. Then it works in Firefox (all versions) and
Chrome 3 but not
Chrome 5 (I don't have
Chrome 4 so I'm not shure about that specific version (and don't know if it's even possible to download a specific
Chrome version?) -- but for
Chrome 5 I'm very sure it doesn't work).
