请问红色代码部分应该怎么写？不用母版页的时候id="+Content.id.value,"这里是id="+form1.id.value,"。可使用了母版页，没有form1了。求助！！！

function Button7_onclick()
{
var str=showModalDialog("xuanzerenyuan/xuanzerenyuan.asp?iniurl=wenjianzhonglei_guanliyuan.asp?id="+form1.id.value,"","center:yes;status:yes;scroll:no;help:no;dialogWidth:500px;dialogHeight:290px");

if(str!=null)
{
var mingcheng,bianhao,string;
string=str.split("$");
mingcheng=string[0];
bianhao=string[1];
if(bianhao.length>7)
{
window.alert("只能选择一个!");
return false;
}
window.document.form1.fuzeren.value=mingcheng;
window.document.form1.gonghao.value=bianhao;
}
}
</script>
<form id="form1" method = "post" >
.................
</form>
</asp:Content>

加上form的话（如上）form的属性不能加runat ="server"属性
这样可以打开选择窗口了
可是文本框还是取不到值

没人解答，自己顶上去

你是用ASP作的吗
怎么下段是ASP不是ASPX
xuanzerenyuan/xuanzerenyuan.asp?iniurl

用Master的FindControl()方法来取值

已经解决
