jQuery开发者都需要知道的5个小技巧_jquery

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 = "1.8" )
{
//do something
}

5.检查存在的元素

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