JQuery是个不错的框架，以下总结了5个每个网站开发者都应该知道的小技巧：

1.禁用右键菜单



$(document).ready(function(){    $(document).bind("contextmenu",function(e){returnfalse;});});



2.让字体闪烁



jQuery.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.准备文档替换方案



$(function(){//document is ready do something});



4.检测browser



// Safariif( $.browser.safari){//do something} //Above IE6if($.browser.msie&& $.browser.version>6){//do something} // IE6 and belowif($.browser.msie&& $.browser.version<=6){//do something } // Firefox 2 and above if ($.browser.mozilla && $.browser.version >= "1.8" ){//do something}



5.检查存在的元素



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