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...
}
