插件原理
　　所有彈出層的原理都差不多，就是用一個全屏半透明DIV做遮罩層，在這個遮罩層上再顯示出一個層放要顯示的內(nèi)容，其他的就是CSS的運用了。
　　本插件為了使用簡單，把JS跟CSS封裝在了一個JS文件(插件)中，所以使用起來非常方便，做到了一行代碼調(diào)用。
插件源代碼
　　插件(jquery.artwl.thickbox.js)的源碼如下：

復制代碼代碼如下:

;(function ($) { 
$.extend({ 
artwl_bind: function (options) { 
options=$.extend({ 
showbtnid:"", 
title:"", 
content:"" 
},options); 
var mask = '<div id="artwl_mask"></div>'; 
var boxcontain = '<div id="artwl_boxcontain">\ 
<a id="artwl_close" href="javascript:void(0);" title="Close"></a>\ 
<div id="artwl_showbox">\ 
<div id="artwl_title">\ 
<h2>\ 
Title</h2>\ 
</div>\ 
<div id="artwl_message">\ 
Content<br />\ 
</div>\ 
</div>\ 
</div>'; 
var cssCode = 'html, body, h1, h2, h3, h4, h5{margin: 0px;padding: 0px;}\ 
#artwl_mask{background-color: #000;position: absolute;top: 0px;left: 0px;width: 100%;height: 100%;opacity: 0.5;filter: alpha(opacity=50);display: none;}\ 
#artwl_boxcontain{margin: 0 auto;position: absolute;z-index: 2;line-height: 28px;display: none;}\ 
#artwl_showbox{padding: 10px;background: #FFF;border-radius: 5px;margin: 20px;min-width:300px;min-height:200px;}\ 
#artwl_title{position: relative;height: 27px;border-bottom: 1px solid #999;}\ 
#artwl_close{position: absolute;cursor: pointer;outline: none;top: 0;right: 0;z-index: 4;width: 42px;height: 42px;overflow: hidden;background-image: url(/Images/feedback-close.png);_background: none;}\ 
#artwl_message{padding: 10px 0px;overflow: hidden;line-height: 19px;}'; 
if ($("#artwl_mask").length == 0) { 
$("body").append(mask + boxcontain); 
$("head").append("<style type='text/css'>" + cssCode + "</style>"); 
if(options.title!=""){ 
$("#artwl_title").html(options.title); 
} 
if(options.content!=""){ 
$("#artwl_message").html(options.content); 
} 
} 
$("#"+options.showbtnid).click(function () { 
var height = $("#artwl_boxcontain").height(); 
var width = $("#artwl_boxcontain").width(); 
$("#artwl_mask").show(); 
$("#artwl_boxcontain").css("top", ($(window).height() - height) / 2).css("left", ($(window).width() - width) / 2).show(); 
if ($.browser.msie && $.browser.version.substr(0, 1) < 7) { 
width = $(window).width() > 600 ? 600 : $(window).width() - 40; 
$("#artwl_boxcontain").css("width", width + "px").css("top", ($(window).height() - height) / 2).css("left", ($(window).width() - width) / 2).show(); 
$("#artwl_mask").css("width", $(window).width() + "px").css("height", $(window).height() + "px").css("background", "#888"); 
$("#artwl_close").css("top", "30px").css("right", "30px").css("font-size", "20px").text("關閉"); 
} 
}); 
$("#artwl_close").click(function () { 
$("#artwl_mask").hide(); 
$("#artwl_boxcontain").hide(); 
}); 
}, 
artwl_close:function(options){ 
options=$.extend({ 
callback:null 
},options); 
$("#artwl_mask").hide(); 
$("#artwl_boxcontain").hide(); 
if(options.callback!=null){ 
options.callback(); 
} 
} 
}); 
})(jQuery); 

調(diào)用也非常簡單，在頁面引入此JS文件后，在頁面加載方法中調(diào)用如下代碼即可：
$.artwl_bind({ showbtnid: "btn_show", title: "From Cnblogs Artwl", content: $("#Content").html() });
　　這三個參數(shù)非常簡單，第一個是彈出層觸發(fā)事件的元素ID，第二個為彈出層的標題，第三個為彈出層的內(nèi)容
注意事項
　　為了使用方便，本插件把JS跟CSS寫在了一個文件中，如果要調(diào)整彈出層的樣式可以修改如下CSS即可。
