参考：5 useful jquery tricks you should know

1.禁用鼠标右键

javascript$(document).ready(function() { $(document).bind("contextmenu", function(e) { return false; }); });

2.让内容闪烁起来

javascript$.fn.flash = function(color, duration) { var current = this.css('color'); this.animate( {color: 'rgb(' + color + ')'}, duration / 2); this.animate( {color: current}, duration / 2); } $('#someid').flash('255,0,0', 1000);

3.DOM加载完成的简写形式

javascript$(function() { // document is ready.. })

4.探测浏览器

// Safari if( $.browser.safari ) { //do something } //Above IE6 if ($.browser.msie && $.browser.version > 6 ) { //do something } // IE6 and below if ($.browser.msie && $.browser.version < 6 ) { //do something } // Firefox 2 and above if ($.browser.mozilla &amp;&amp; $.browser.version &gt;= "1.8" ) { //do something }

5.判断元素是否存在

javascriptif($("#someDiv").length) { // yes it does, do something... }
