图片预加载

(function($) { var cache = []; // Arguments are image paths relative to the current page. $.preLoadImages = function() { var args_len = arguments.length; for (var i = args_len; i--;) { var cacheImage = document.createElement('img'); cacheImage.src = arguments[i]; cache.push(cacheImage); } } jQuery.preLoadImages("image1.gif", "/path/to/image2.png");

在新窗口打开链接 (target=”blank”)

$('a[@rel$='external']').click(function(){ this.target = "_blank"; }); /* Usage: <a href="http:///svn/trunk/html5.js"></script> <![endif]-->

测试浏览器是否支持某些 CSS3 属性

var supports = (function() { var div = document.createElement('div'), vendors = 'Khtml Ms O Moz Webkit'.split(' '), len = vendors.length; return function(prop) { if ( prop in div.style ) return true; prop = prop.replace(/^[a-z]/, function(val) { return val.toUpperCase(); }); while(len--) { if ( vendors[len] + prop in div.style ) { // browser supports box-shadow. Do what you need. // Or use a bang (!) to test if the browser doesn't. return true; } } return false; }; })(); if ( supports('textShadow') ) { document.documentElement.className += ' textShadow';

获取 URL 中传递的参数

$.urlParam = function(name){ var results = new RegExp('[\\?&]' + name + '=([^&#]*)').exec(window.location.href); if (!results) { return 0; } return results[1] || 0; }

禁用表单的回车键提交

$("#form").keypress(function(e) { if (e.which == 13) { return false; } });
