问题 UPDATE: (recap, fiddle and bounty) This question hasn't been getting too much attention, so I'm going to spend some rep on it. I know I tend to be overly verbose in both my answers and questions. That's why I went ahead and set up this fiddle, which is, in my view, a decent representation of the kind of code I'm currently having to use to come close to a bubbling change event. A couple of issues I'm trying to resolve: The pseudo-change event doesn't fire on a select element, unless it looses

问题 In order to add events we could use this simple 1st solution : function AddEvent(html_element, event_name, event_function) { if(html_element.attachEvent) //Internet Explorer html_element.attachEvent("on" + event_name, function() {event_function.call(html_element);}); else if(html_element.addEventListener) //Firefox & company html_element.addEventListener(event_name, event_function, false); //don't need the 'call' trick because in FF everything already works in the right way } or this 2nd

问题 I have an iframe that takes up the entire window (100% wide, 100% high), and I need the main window to be able to detect when the mouse has been moved.

Also tried wrapping the iframe in a div like so: <div onmousemove="alert('justfortesting');"><iframe src="foo.bar"></iframe></div> .. and it didn't work. Any suggestions? 回答1: If your target isn't Opera 9 or lower and IE 9 or lower you can use css attribute

问题 In IE, I can just call element.click() from JavaScript - how do I accomplish the same task in Firefox? Ideally I'd like to have some JavaScript that would work equally well cross-browser, but if necessary I'll have different per-browser JavaScript for this. 回答1: The document.createEvent documentation says that " The createEvent method is deprecated. Use event constructors instead. " So you should use this method instead: var clickEvent = new MouseEvent("click", { "view": window, "bubbles":

问题 This question already has answers here : Adding event listeners to dynamically added elements using jQuery [duplicate] (4 answers) Closed 5 years ago .

For example, let's say I dynamically load notifications,

问题 I took a look at this is-javascript-location-href-call-is-asynchronous and this what the heck is the event loop anyway but there is no explanation of the defined behavior of href of window.location : The following is the script order in source code: 1. DOM elements 2. <script> at the bottom having doc.ready. 3.Further <script> tags. 4. doc.ready's callback goes into the CB queue because all DOM elements are available in step 1 and there are only further script tags ( This callback stays in
