Summary Different frame navigation policy in various browsers.

According to the policy discussed in bug 15936, I've created a scenario in which various browsers act differently. Assume that the following files are located at http://aaa.bbb.com/ Note: If you want to try out this example, change the value of document.domain accordingly in these files! It should be a suffix of the real domain in which these files reside. ==================================== <!-- navigation.htm --> <html> <head> <title></title> <script language="javascript">document.domain='bbb.com';</script> </head> <frameset name="main" cols="503,*"> <frame name="left" src="left.htm" /> <frame name="right" src="right.htm" /> </frameset> </html> ================================ <!-- left.htm --> <html> <head> <title></title> <base target='right'> </head> <body> <a href='helloWorld.htm'>HelloWorld</a> </body> </html> ================================= <!-- right.htm --> <html> <head> <title></title> </head> <body> <script language="javascript">document.domain='bbb.com';</script> </body> </html> ================================= <!-- helloWorld.htm --> <html> <body> <h1>Hello World!</h1> </body> </html> ================================= Open navigation.htm, and then click the "HelloWorld" link: IE7: will open the link in a new tab instead of the target frame. IE6, Firefox2/3, Safari 3.0.3: will open the link in the target frame. Current WebKit: will do nothing. This problem affects a popular forum in China: http://dzh.mop.com In this forum, if you click a link in the left panel, current WebKit will not open the link. (Due to some other reasons, IE7 works fine with this site.)

When the browser's frame navigation policy wants to prevent a frame from being navigated, the most user-friendly behavior is to open a new window, as in IE7. I think the patch for bug 16522 will provide this behavior.

Has the patch been submitted into the WebKit code base? I compiled WebKit 2 or 3 hours ago, and ran safari with it. And it did exactly what I described in previous post.

I tried using http://dzh.mop.com in IE7. Clicking on links in the left-hand frame opens a new tab with the content. WebKit should have the same behavior after the patch for Bug 16522 lands. > I have no right to access bug 16522. Has the patch been submitted into the > WebKit code base? The patch has not been committed yet, but hopefully it will be soon. I don't have authorization to add you to the bug, but it's a bug about this and one other issue with frame navigation. If you'd like the links to open in the right-hand frame instead of in new tabs in IE7 (and future-Safari), you can put the left-hand frame in the same origin as either the top or right-hand frame (or both). The simplest way to do this is to set document.domain = "mop.com" in the left-hand frame.

The behavior in WebKit (as of r29380) now matches the IE7 behavior. Clicking links in the left frame now causes a new window to be opened.

After testing the reported issue I can report that WebKit, Firefox 3 and IE7 matches the same behavior - they open links in new tab/window. Only Opera 9.5 behaves differently, but I think they changes his behavior in a future. I think we can close the report now since three major browsers behave identically now.
