Is there a way to fire over events ignoring z-index?

由 独自空忆成欢 提交于 2019-12-18 13:35:27
问题 If I have something like this: Is there a way to fire the mouseover events on BOTH divs? Edit: Sorry all .. I tried to simplfy the problem so it was clear to understand and I forgot to mention I have more than 100 divs like that so probably those solutions don't work. I'm going to see if I can adpat them. Many thanks everybody anyway. 回答1: I put together a working example here with JSFiddle: http://jsfiddle.net/gfosco/CU5YT/ It's similar to madeinstefanos answer, but specific to your example.

window.resize in jquery firing multiple times

由 匆匆过客 提交于 2019-12-18 13:07:37
问题 I have the following javascript/jquery code in an HTML file: <html> <head> <script src="http://code.jquery.com/jquery-1.6.2.min.js" type="text/javascript"></script> <script language="javascript"> $(window).resize(function(){alert('hi');});</script> </head> <body> resize me </body> </html> It appears relatively straight forward, however when I re size the browser window, I get two successive alert windows on Chrome and IE9 and I seemingly crash FF5. What am I missing? Is it one fire per

How to detect `focusin` support?

由 喜你入骨 提交于 2019-12-18 12:21:39
问题 Thanks to Perfection kills, we can use the following JavaScript to detect event support: function hasEvent(ev) { var elem = document.createElement('a'), type = 'on' + ev, supported = elem[type] !== undefined; if (!supported) { elem.setAttribute(type, 'return;'); supported = typeof elem[type] === 'function'; } elem = null; return supported; } This works for about the only time I need it: detecting mouseenter support; hasEvent('mouseenter') will return false in Chrome, Firefox, etc., as it

Chrome (maybe Safari?) fires “blur” twice on input fields when browser loses focus

由 半腔热情 提交于 2019-12-18 11:49:43
问题 Here is an interesting jsfiddle. In Firefox: Run the fiddle Click in text input Click somewhere else. Should say "1 blurs". Click in the text input again. ALT-TAB to another window. Fiddle should now say "2 blurs". In Chrome, at step 5, it says "3 blurs". Two separate "blur" events are fired when the whole browser loses focus. This is of interest because it means that it's not safe to assume, in a "blur" handler, that the element actually had focus just before the event was dispatched; that

How to add an onchange event to a select box via javascript?

由 人盡茶涼 提交于 2019-12-18 11:41:49
问题 I've got a script where I am dynamically creating select boxes. When those boxes are created, we want to set the onchange event for the new box to point to a function called toggleSelect(). I can't seem to get the syntax right to create the onchange event. Can someone tell me what I'm doing wrong? It doesn't throw an error, but doesn't work, either. col = dataRow.insertCell(0); var transport_select = document.createElement('select'); transport_select.id = transport_select_id; transport_select

Single thread concept of JavaScript running in browser

由 浪尽此生 提交于 2019-12-18 11:29:13
问题 The following figure is taken from Chapter 3 of the book Secrets of the JavaScript Ninja by Jon Resig. Here the author is explaining the browser event loop. The book has to say this : It’s important to note that the browser mechanism that puts the events onto the queue is external to this event loop model. The processing necessary to determine when events have occurred and to push them onto the event queue doesn’t participate in the thread that’s handling the events. So my question is it
