问题 Couple of minutes ago, I answered the question: What is the difference between focusin/focusout vs focus/blur in jQuery? The answer was: Short answer: focusin bubbles, focus does not. focusout bubbles, blur does not. I tested it, it's true, but I encountered a weird thing while trying to set up a DEMO: $('#test').on('focusin focusout focus blur change', function(e) { console.log(e.type + 'event bubles? : ' + e.bubbles); }); focusin and focusout give me e.bubbles == false Is it a

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

Here's a sample using the console.log of firebug to show you which object is triggering the focusin event: http://jsbin.com/axefo3/11 1) click the first link: yellow div shows 2) hit the tab key: It should tab into the link within the yellow div It does that, but then it triggers the focusin event and, for some reason, it appears to bubble up again to the red div, which is told to then close

Sounds like a bug in jQuery. Did you test this on a

How to exclude Id from focusout

阅读更多关于 How to exclude Id from focusout

With Jquery, focusout is just called when you click anywhere out of the focused area when "focusout" is set. How do I exclude some id(s) from activiting the "focusout" function. ? e.g here. You have an input text field ( id="A")that hides some div on focus and shows that very div when it's out of focus, so but now it obviously will show the div when you click anywhere out of this ("#A") input field. Question is, how do you set some id(maybe a select field(Id="B" next to it), not to fire off the "focusout" function. Hope it makes sense. Try using relatedTarget event property: $('#id').focusout
