Aspx中为flash生成一个鼠标点击事件

 以下是用datalist绑定了一些flash视频。客户端点击这个视频，则跳出一个网页。
<Script     language="javascript">   
    function     OpenAdvertPage(URL)     {  
    window.open("b.html","_blank");  
    return     false;  
    }     
    </script>  
<asp:datalist id="DataList1" runat="server" RepeatColumns="1">
       <ItemTemplate>
        <div align="center" onMouseDown="OpenAdvertPage('http://www.baidu.com/')">
