Hi jQuery community,
I've written a complex jQuery table plugin wich supports different selection models (single, multiple, exclusive), nested/hierarchical tables (like a tree) etc. Everything works well, but now - while the application goes testing by some clients - I stumbled by an very ugly performance issue in IE. The problem appers only on IE machines - very remarkable on slower lowend hardware. Anyway FF and Mozilla is fine at all. For an easier problem tracking I've extracted the problematic code from the plugin and provide a simple test example with the embedded plugin code. Please follow the next steps and try to retrace the problem. * Load the the test page from http://members.inode.at/396869/jq/ into your browser * Try moving the mouse (quick) over the table and watch the performance (highlight row follows mouse) and the mouse pointer type is usually the pointer * Now click ***somewhere*** in the page - doesn't matter if on the table or on the body background! * Try moving the mouse over the table again and watch the performance and the mouse pointer now... Recognize it? The highligtning is now very bumpy und the mouse pointer toggles rapidly between the hour glass and the pointer. There is NO event registration by my plugin on the page nether on the background. What happens after clicking on the page? What is the reason for the slow down of the browser? What kind of code is executing after the click? I don't have any idea... Is it a jQuery, a IE browser or a plugin problem? My config Thinkpad T60,Windows XP SP2, IE6.0.2900.2180.xpsp. 050928-1517. As jQuery version i used 1.1.2 and the latest 1.1.3b. Same effekt. The length of the table is not an issue. Effekt also happens with 10 rows... Thanks in advance for any hint, Stefan Flick
