Array-like object in javascript

阅读更多关于 Array-like object in javascript

Looking through the dom.js source from the Closure library I found this (in goog.dom.getElementsByTagNameAndClass_ ): if (opt_class) { var arrayLike = {}; var len = 0; for (var i = 0, el; el = els[i]; i++) { var className = el.className; // Check if className has a split function since SVG className does not. if (typeof className.split == 'function' && goog.array.contains(className.split(' '), opt_class)) { arrayLike[len++] = el; } } arrayLike.length = len; return arrayLike; } What would be the benefit of doing this over a regular array? The author of the code used empty JavaScript object as a

Using DOMContentReady considered anti-pattern by Google

阅读更多关于 Using DOMContentReady considered anti-pattern by Google

A Google Closure library team member asserts that waiting for DOMContentReady event is a bad practice. The short story is that we don't want to wait for DOMContentReady (or worse the load event) since it leads to bad user experience. The UI is not responsive until all the DOM has been loaded from the network. So the preferred way is to use inline scripts as soon as possible. Since they still don't provide more details on this, so I wonder how they deal with Operation Aborted dialog in IE. This dialog is the only critical reason I know to wait for DOMContentReady (or load) event. Do you know

How can I log an HTML element as a JavaScript object?

阅读更多关于 How can I log an HTML element as a JavaScript object?

Using Google Chrome, if you console.log an object, it lets you inspect the element in the console. For example: var a = { "foo" : "bar", "whiz" : "bang" }; console.log(a); This prints out Object which can be inspected by clicking on arrows next to it. If however I try to log an HTMLElement: var b = goog.dom.query('html')[0]; console.log(b); This prints out <html></html> which can not be inspected by clicking on arrows next to it. If I want to see the JavaScript object (with its methods and fields) instead of just the DOM of the element, how would I do that? Use console.dir : var element =

How do I find out what functions are called when a button is pressed in Chrome Console?

阅读更多关于 How do I find out what functions are called when a button is pressed in Chrome Console?

I am trying to teach myself the Google Closure javascript library. I am examining the TreeControl UI widget. How can I use Chrome Console to analyze what functions are run when I click on the "Cut" button in the demo below? For instance, can I somehow set a break point for that? I've tried viewing the source and looking around, but I feel that Chrome Console may offer a more systematic method. https://github.com/google/closure-library/blob/master/closure/goog/demos/tree/demo.html With the Chrome Developer Tools window open, click on the "Sources" tab.
