问题 I have an issue with Google Analytics Event Tracking that is only apparent on Chrome and no other browser. I have the following Google Analytics Tracking Code firing on my site for a click on an anchor link: _gaq.push(['_trackEvent', 'Basket Remove', product_name, product_code, product_price, false]); _gaq.push(['rollup._trackEvent', 'Basket Remove', product_name, product_code, product_price, false]); Using a Web Proxy tool I can see that the first one is firing, but the second one is not.

问题 The below fadeIn, fadeOut effect works fine in Firefox 3.0 but it doesn't work in IE 7 ... Whay is that and what's the trick?

问题 Which browsers do not support the get and set methods for object prototypes? I believe this is a feature of ES5, an I know it works in Chrome, but I am wondering if it is safe to use for ajax apps. Here's an example: var foo = function () {}; foo.prototype = { get name () { return this._name; }, set name (n) { this._name = n || "bar"; } }; 回答1: Here's a compatibility table for you. http://kangax.github.com/es5-compat-table/ See the Getter in property initializer and Setter in property

问题 I have this scrollable div, which (on my Mac in Chrome) hides the scrollbar when I don't scroll. On windows 8 however, it doesn't work in Chrome and Firefox.

问题 Is this code safe in all major browsers? var string = '123' alert(string[1] == '2') // should alert true 回答1: No, it's not safe. Internet Explorer 7 doesn't support accessing strings by index. You have to use the charAt method to be compatibale with IE7: var string = '123'; alert(string.charAt(1) == '2'); 回答2: Everything in JavaScript is an object; arrays, functions, strings, everything. The piece of code you put up is perfectly valid, although a little confusing - there are much better ways

问题 Here is some really simple markup and CSS: a { color: red; } a:link { color: green; } <a href="#">one</a> <a href="">two</a> <a href>three</a> <a>four</a> FIDDLE Now from the spec: in HTML4, the link pseudo-classes apply to A elements with an "href" attribute.

So I used inspect element and I saw that the a:link selector actually overides the a selector in
