Javascript 对话框 (遇到 Ajax Load无法加载问题）

一个弹框公共组件，实现类似Discuz! 的登入效果。

/*
文档名称： 无模式对话框弹出组件

//               HTML文本  宽度     高度     绑定关闭    
function sAlert(htmlStr,msgWidth,msgHeight,closeid){
   //alert(htmlStr);
   var msgw,msgh; 
   msgw=msgWidth!=null?msgWidth:400;//Width

   document.getElementById("msgDiv").innerHTML=htmlStr; 
   document.getElementById("bgDiv").onclick = function(){cAlert();}
   try{//处理未绑定异常
      document.getElementById(closeid).onclick = function(){cAlert();}
   }
   catch(error){
      alert("ERROR");
   }
}

function cAlert()
{
   document.body.removeChild(document.getElementById("bgDiv")); 
   document.body.removeChild(document.getElementById("msgDiv")); 
}

在火狐下，遇到了无法弹出的问题，导致问题产生的原因是Load方法未执行完成，就去调用其结果。

将调用过程放到  回调函数里面就OK~~

 var $html = $("<div id=\"temphtmlNodete\" style=\"display:none;\"></div>");
           $.ajaxSetup ({cache: false }); 
           $html.load("密码找回.html",function(){
                               sAlert($html.html(),750,400,"close");
                                               }
