1.禁用右键菜单

$(document).ready(function(){

$(document).bind("contextmenu",function(e){

return false;

});

});

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

// 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 && $.browser.version >= "1.8" )

{

//do something

}

5.检查存在的元素

if ($("#someDiv").length) {

//yes it does ,do something

}
