js如下:
<script language="javascript">
//登陆弹出对话框，并使背景元素不可用
var div_width = 300;
var div_height = 200;
function showWindow(width,height){
location.href="#";
width = div_width;
height = div_height
var windowstr= document.getElementById("popLayer").innerHTML;
document.getElementById("infoDiv").innerHTML=windowstr;
document.getElementById("infoDiv").style.left=((document.body.clientWidth-width)>0?(document.body.clientWidth-width):0)/2+"px";
document.getElementById("infoDiv").style.top=200+"px";
document.getElementById("infoDiv").style.zIndex=10001;
document.getElementById("infoDiv").style.width=width;
document.getElementById("infoDiv").style.height=height;
document.getElementById("infoDiv").style.border="3px solid #0099ff";
document.getElementById("tranDiv").style.height=document.body.clientHeight+ "px";
document.getElementById("tranDiv").style.width=document.body.clientWidth+ "px";
document.getElementById("tranDiv").style.display="";
document.getElementById("tranDivBack").style.display="";
document.getElementById("tranDivBack").style.zIndex=10000;
document.getElementById("infoDiv").style.display="";
}
function closeWindow(){
document.getElementById("tranDiv").style.display="none";
}

</script>

页面中：

<div style="position:absolute;display:none; left:0px; top:0px;" id="tranDiv">
<div style="position:absolute;left:0px; top:0px; width:100%; height:100%;background-color:#000000;filter:alpha(Opacity=30)" id="tranDivBack"> </div>
<div align='center'style='position:absolute;left:0px; top:0px; width:100%; height:100%; background-color:#e5edf5;background-image:url(images/bestnetqywimg/tccbg.gif);' id='infoDiv'></div>
</div>


<div id="popLayer" style="display:none"><form id="formdl" name="formdl" method="post" action=""><br /><font align="center" color="#0000ff" size="3"><b>---手机号码先登录---</b></font><br /><br />

<br/>
<input type="submit" name="Submit" class="bntccanniu" value="登录" /> <input type="button" name="Submit1" class="bntccanniu" value="取消" onclick="closeWindow();"/>

</form>
</div>
<a href="javascript:;">点击此处看看</a>

是想做什么效果，如果是只是想其弹出，只要新建个div 或者事先在页面中建个隐藏的div，然后当按下按钮的时候将其显示，先用document.getElementById("id名字")把对象获取过来，然后在将其样式设置为现实，或者直接在页面中创建，用document.creatElement("div");来实现
