Attempt to choose one of the areas using the checkboxes II Issue: Checkboxes for choosing city or area don't work for selecting search parameters in www.mlslistings.com III Conclusion: The "checkbox" is faked checkbox, it is actually an image embraced with a link. When click on it, javascript function _RSNodeClicked() is invoked to execute the functionalities. In webkit, the functionalities fails because there is an uncaught exception thrown in backend, which is: ...... Uncaught TypeError: Cannot read property 'nodeName' of null ...... This exception is thrown because the DOM attribute document.activeElement is not correct in webkit. When click on a link, the document.activeElement is body element in webkit, however it should be the link element itself, like what in IE and FF. IV Other Browsers: IE7: ok FF3: ok V Nightly tested: 46809 Bug in Chromium : http://code.google.com/p/chromium/issues/detail?id=14436 280343 1 peter_lenahan 2010-09-16 14:01:25 -0700 Here is a JavaScript workaround to the ActiveElement problem in Safari and Chrome. Add a listener on the mousedown event or any other event which you are depending on. The event listener will keep the status of the active element, so when you want to reference it, you can use it. // Declare a global variable to track the elements var myActiveElement = null; // define the event listener first function _dom_trackActiveElement(evt) { if (evt && evt.target) { myActiveElement= evt.target == document ? null : evt.target; } } if(navigator.userAgent.toLowerCase().indexOf('webkit') > -1) { // Register the event listener here document.addEventListener("mousedown",_dom_trackActiveElement,true); } ... Now in a method where I need to use the activeElement, I have it available as a global variable it is always set in the event listener which tracks it. if (myActiveElement != null) myfunctioncall(myActiveElement); else myfunctioncall(document.activeElement); 1890550 2 ahmad.saleem792 2022-08-11 04:40:03 -0700 I am able to reproduce this bug in Safari 15.6 on macOS 12.5 using attached "reduction" test case and it shows following across browsers upon clicking link: *** Safari 15.6 on macOS 12.5 *** document.activeElement is: BODY *** Firefox Nightly 105 *** document.activeElement is: A *** Chrome Canary 106 *** document.activeElement is: A _____ I am not sure on web-spec but I am going to change status to "New" since Safari is different from other browsers. If Safari / Webkit is right, please ignore and mark this as "RESOLVED WONTFIX". Thanks! 1892573 3 ap 2022-08-19 17:56:49 -0700 The website is no longer affected. I think that this is essentially a dupe of bug 22261, although we could theoretically change document.activeElement temporarily, only while handling the click. We do set the :active pseudo-class, after all. *** This bug has been marked as a duplicate of bug 22261 *** 38402 2009-08-21 15:10:16 -0700 2009-08-21 15:10:16 -0700 reduced testcase test-standard (1).html text/html 751 jasneet PCFET0NUWVBFIGh0bWwgUFVCTElDICItLy9XM0MvL0RURCBYSFRNTCAxLjAgVHJhbnNpdGlvbmFs Ly9FTiIgImh0dHA6Ly93d3cudzMub3JnL1RSL3hodG1sMS9EVEQveGh0bWwxLXRyYW5zaXRpb25h bC5kdGQiPg0KPGh0bWwgeG1sbnM9Imh0dHA6Ly93d3cudzMub3JnLzE5OTkveGh0bWwiPg0KPGhl YWQ+DQo8bWV0YSBodHRwLWVxdWl2PSJDb250ZW50LVR5cGUiIGNvbnRlbnQ9InRleHQvaHRtbDsg Y2hhcnNldD11dGYtOCIgLz4NCjx0aXRsZT5VbnRpdGxlZCBEb2N1bWVudDwvdGl0bGU+DQo8c2Ny aXB0Pg0KZnVuY3Rpb24gdGVzdFRoaXMoKSB7DQoJaWYgKGRvY3VtZW50LmFjdGl2ZUVsZW1lbnQp IHsNCgkJYWxlcnQoImRvY3VtZW50LmFjdGl2ZUVsZW1lbnQgaXM6ICIgKyBkb2N1bWVudC5hY3Rp dmVFbGVtZW50LnRhZ05hbWUpOw0KCX0gZWxzZSB7DQoJCWFsZXJ0KCJkb2N1bWVudC5hY3RpdmVF bGVtZW50IGlzOiAiICsgZG9jdW1lbnQuYWN0aXZlRWxlbWVudCk7DQoJfQ0KfQ0KPC9zY3JpcHQ+ DQo8L2hlYWQ+DQoNCjxib2R5Pg0KV2hlbiBjbGljayBvbiBiZWxvdyBsaW5rLCB0aGUgRE9NIGF0 dHJpYnV0ZSBkb2N1bWVudC5hY3RpdmVFbGVtZW50IHNob3VsZCBiZSByZWZlcmluZyB0byB0aGUg bGluayBpdHNlbGY8YnIgLz4NCjxhIGhyZWY9ImphdmFzY3JpcHQ6IHRlc3RUaGlzKCkiID5DbGlj ayBtZSB0byBzZWUgaWYgZG9jdW1lbnQuYWN0aXZlRWxlbWVudCBpcyBtZTwvYT4NCjwvYm9keT4N CjwvaHRtbD4NCg==
