Thanks, guys. there's a problem that i loaded other site's pages into my iframe. that caused i got permission denied when trying to access the DOM of the contained web page. It doesn't seem i can get around this permission issue.
Johan, I tried your suggestions. my domain of the web app is "http://localhost/"; say the domain of the web page I included in an iframe is "http:// www.google.com/" I have @include-d both domains in my GM scripts. my GM script looks like this: .... .... if ('mybrowser' != window.name) return; .... var iframeEl = document.getElementById('mybrowser'); var doc; if ( iframeEl.contentDocument ) { // DOM doc = iframeEl.contentDocument; } var allLinks; allLinks = doc.getElementsByTagName('a'); // try to modify the css of all the links... ... .... here's what happened: 1. the window.name doesn't return anything, it's empty. 2. i got "Error: Permission denied to call method HTMLDocument.getElementsByTagName" when executing: allLinks = doc.getElementsByTagName('a'); This is caused by doc is not accessible. I can access its parent the iframeEl element though. so looks like we have no way to invoke GM on the iframe that contains external site's content. correct? thanks much.
