这个简化版不能在别的框架弹出层的，所以也就没有了那个cssurl属性了，也没有target 属性了

复制代码代码如下:

String.prototype.replaceAll = function(s1,s2){ 
return this.replace(new RegExp(s1,"gm"),s2); 
}; 
(function($){

使用方法：
（1）显示层：

代码如下:

function show() 
{ 
$.layerSetup({ 
id:"abc",//弹出层的ID 
title:"test",//标题 
content:&#39;test&#39;,//内容 
isbg:false,//是否显示背景遮照层 
opacity:0.3,//背景遮照层的透明度，值越大透明度越低，0为完全透明，1为不透明 
templete:&#39;<p class="showwint_mini_title"><span class="showwint_mini_close_btn">
<a href="javascript:void(null);" class="layerclose"></a></span>
<span class="showwint_mini_title_content" id="@moveid@"><span id="@titleid@"></span>
</span></p><p class="showwint_mini_content"><p class="showwint_mini_content_content" id="@contentid@"></p>
</p>&#39;//模板 
}); 
$.layershow(); 
}
