关于javascript对话框

你好.
你可以設計一個DIV層.如下:
HTML code:<div id="divUserCheck" style="position:absolute;top:200px;left:300px;width:200px;height:150px;border:1px red solid;">
<table>
<tr>
<td>userID</td><td><asp:TextBox id="txtUserID" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td>userPassword</td><td><asp:TextBox id="txtUserID" runat="server"></asp:TextBox></td>
</tr>
<tr>
<td colspan="2" align="center"><asp:Button id="btnCheck" runat="server" text="login"></asp:TextBox>
<input type="button" id="btnCloseMe" value="Close Me" onclick="divUserCheck.style.display='none';">
</td>
</tr>
</table></div>
<div>
<ul>
<li><a href="javascript:void(0);">baidu.com</a></li>
<li><a href="javascript:void(0);">Google</a></li>
<li><a href="javascript:void(0);">Yahoo</a></li>
</ul>
</div>
添加JS代碼:
JS code:<head>
<script>window.onload=function()
{
    var divUserCheck=document.getElementById("divUserCheck");
    for(var i=0;i<document.links.length;i++)
    {
       var thisLink=document.links[i];
       thisLink.onclick=function()
       {
          divUserCheck.style.display='';
          divUserCheck.style.posTop=event.clientY;
          divUserCheck.style.posLeft=event.clientX;
       }
    }
}</script>
</head>

實現驗証和授權鏈接你可以在后台寫代碼。good luck.
