页面状态加载.... JS

代码

createMask();
function createMask()
{ 
    document.write( " <div id='shield'  style='Z-INDEX:1000;filter:alpha(opacity=10);BACKGROUND-COLOR:#cccccc;LEFT:0;WIDTH:100%;POSITION:absolute;TOP:0;HEIGHT:100%'><br>&nbsp;&nbsp;&nbsp;<img src='images/loading.gif'>数据正在读入中,请稍等...</div> " );
} 


document.onreadystatechange  =   new  Function( " hiddenLay(); " );
function hiddenLay()
{
     if (document.readyState == " complete " )
    {
         document.getElementById( " shield " ).style.display = " none " ;
    }
}
存成js,再head里引用就可以了
