我想做一个像浏览似的按钮，点击按钮弹出一窗口，然后点击弹出窗口里面的摸个值后，窗口自动关闭，并将值传回到父窗口！

Response.Write(" <script language=javascript>parent.document.getElementById("client").value="+client+"; window.close(); </script>");

弹出窗口将参数值回传到父窗口
方法1：window.open
father webform
按钮<asp:button id="Button2" runat="server" Text="Button"></asp:button>
显示返回值的文本框<INPUT id="txt" type="text" runat="server">，这里一定要是htmlcontrol，如果是webcontrol是得不到返回值的。

private void Button2_Click(object sender, System.EventArgs e)
{
Response.Write("<script>window.open('son.aspx')</script>");
}

son webform
<INPUT id="ipload" runat="server" style="Z-INDEX: 101; LEFT: 232px; POSITION: absolute; TOP: 64px"
type="file">上传文件的控件
<asp:Button id="Button1" style="Z-INDEX: 102; LEFT: 280px; POSITION: absolute; TOP: 136px" runat="server" Text="Button"></asp:Button>
button事件里面的内容是：
Response.Write("<script>window.opener.document.all['txt'].value='"+ipload.PostedFile.FileName.ToString()+"';</script>");
Response.Write("<script>window.opener.forms[0].submit();</script>");
Response.Write("<script>window.close();</script>");

方法2 window.showModalDialog()
父窗口
<asp:button id="Button1" style="Z-INDEX: 101; LEFT: 216px; POSITION: absolute; TOP: 72px" runat="server"
Text="Button"></asp:button><asp:label id="Label1" style="Z-INDEX: 102; LEFT: 304px; POSITION: absolute; TOP: 184px" runat="server">Label</asp:label>
<DIV id="lab" style="DISPLAY: inline; Z-INDEX: 103; LEFT: 368px; WIDTH: 208px; POSITION: absolute; TOP: 32px; HEIGHT: 67px"
runat="server" ms_positioning="FlowLayout"></DIV>
<INPUT id="txt" style="Z-INDEX: 104; LEFT: 160px; POSITION: absolute; TOP: 128px" type="text"
runat="server">
<script language="javascript">
function openmode()
{
var returnValue=window.showModalDialog("popup.aspx");
document.Form1.TextBox1.value=returnValue;

}
</script>
<asp:TextBox id="TextBox1" style="Z-INDEX: 105; LEFT: 168px; POSITION: absolute; TOP: 224px"
runat="server"></asp:TextBox>

code behind那边
private void Page_Load(object sender, System.EventArgs e)
{
Button1.Attributes.Add("onclick","openmode()");
}
子页面
this.Label1.Text=upload.PostedFile.FileName.ToString();
string [] tmp=this.Label1.Text.ToString().Split('\\');
string temp="";
for(int i=0;i<tmp.Length;i++)
{
temp=temp+tmp[i]+"\\\\";
}
temp=temp.Substring(0,temp.Length-2);

this.TextBox1.Text=temp;
Response.Write("<script>window.returnValue='"+temp+"';</script>");
// Response.Write("<script>window.close();</script>");

我给你做了一个例子，你自己看看一下，有看不明白的给我发消息。

真是太谢谢你了！
用asp.net标签就不行吗、？

[forever102]

显示返回值的文本框 <INPUT id="txt" type="text" runat="server">中如果是<asp:textBox>该如何写呢？

[major]

一回事撒把child.aspx.cs中的Response.Write("<script>window.opener.document.getElementById(\"tbParent\").value='" + tbChild.Text + "'</script>");
改成
Response.Write("<script>window.opener.document.getElementById(\"txt\").value='" + tbChild.Text + "'</script>");
就可以了。

用层做，取值方便，弹出窗口也很漂亮，容易控制

[copico]

用JS脚本可以从子窗口控制父窗口的某个控件，来改变值。


子窗口按钮调用的JS代码.

    function updateStr(str)
    {
        parent.document.getElementById("hid_textBox").value = str;
        window.close();
    }

父窗口的hid_textBox控件的值就会改变

[ahbool123]

可以把弹出的窗口换成弹出一个层，这样取值就方便多了，而且不会被浏览器阻止

[forever102]

Response.Write("<script language=javascript>parent.document.getElementById("client").value="+client+"; window.close();</script>");
1楼的大哥在后台这样写怎么有错误啊？

[forever102]

现在窗口用String sUrl = "DetailClient.aspx?client=" + Client.Text;
String sFeatures = "'height=320;width=160;left=100;top=50;location=no;menubar=no;resizable=yes;scrollbars=no;status=no;titlebar=yes;toolbar=no'";
String sScript = "";
sScript += "<script language=javascript>";
sScript += "window.open('" + sUrl + "',''," + sFeatures + ");";
sScript += "</script>";
Response.Write(sScript);
也能打开，就是不知道如何返回值并同时关闭打开的窗口！

用层怎么做啊。给个例子嘛，让我这些新手少走弯路
