An example can be found at http://www.leepfrog.com/~mephraim/mozbug/. If you select an item in the select list, the text boxes are populated. If you change some text in either text box then select another item in the select list, the select list updates the wrong item. The text onChange updates the currently selected list item and should updated the currently selected item in the list, but uses the new selected index. This can be consistently reproduced. Reproducible: Always Steps to Reproduce: 1.Select "Link 1" in select list 2.Update "Link 1" text in Name text box to say "Link 10" 3.Click on "Link 2" in the select List Actual Results: "Link 2" in the select list is updated to say "Link 10" Expected Results: "Link 1" in the select list should be updated to say "Link 10"
Please attach the testcase to the bug (using https://bugzilla.mozilla.org/attachment.cgi?bugid=260850&action=enter) so it won't get lost. Chances are, the issue is that the <select>'s onchange fires onfocus and the other fires onblur. Which is fine (and expected by web pages), but the focus happens before the blur (which is also what web pages expect). > Expected Results: > "Link 1" in the select list should be updated to say "Link 10" To be frank, I don't see why this is expected given common expectations of how focus/blur interact with onchange....
I created a test page (http://www.leepfrog.com/~mephraim/mozbug/index2.html) that displays select focus events and text blur events as they happen. This proves that the Text box blur is happening before the select focus. If you go to http://www.leepfrog.com/~mephraim/mozbug/index2.html and select and item in the select list, it should display the focus event below. Now if you select the text box, then select an item in the select list, you can see the the blur event on the text box is fired before the focus event on the select list. I appreciate your comments, Boris, but I don't think that is what is happening.
Indeed. :) Mats, any idea what's up here?
