1.首先是父页面用window.open打开窗口

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm3.aspx.cs" Inherits="WebApplication17.WebForm3" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">

        function openChild() {

            var k = window.open(‘WebForm2.aspx?id=110&id1=120&id3=130‘, ‘newwindow‘, ‘height=100,width=400,top=0,left=0,toolbar=no,menubar=no,scrollbars=no, resizable=no,location=no, status=no‘);
            //window.showModalDialog("/WebForm2.aspx", "obj", "dialogWidth:335px;status:no;dialogHeight:300px");

        }

</script>
</head>
<body>
    <form id="form1" runat="server">
    <div>
              <input type="text" id="txt10" name="txt10"/>
            <input type="text" id="txt9" name="txt9"/>
                   <input type="text" id="txt11" name="txt11"/>
            <input type="button" id="btn1" name="btn1" value="提交" onclick="openChild()" />

    </div>
    </form>
</body>
</html>
2.这是子页面

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm2.aspx.cs" Inherits="WebApplication17.WebForm2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
    <script type="text/javascript">
        window.onload = function() {

            var k = window.opener;
            document.getElementById("txt1").value = k.document.getElementById("txt10").value;
            var url = location.search;
            if (url.indexOf("id3")!=-1) {
                alert("url id3");
            }
            var theRequest = new Object();
            if (url.indexOf("?") != -1) {
                var str = url.substr(1);

                strs = str.split("&");
                for (var i = 0; i < strs.length; i++) {
                    theRequest[strs[i].split("=")[0]] = (strs[i].split("=")[1]);
                }
            }


        };

    function setFather() {

          //给父窗口空间传值
            var k = window.opener;
            k.document.getElementById("txt10").value =
                document.getElementById("txt1").value;
        }
        //设置返回到父窗口的值
        function retrunValue() {
            var s =
        document.getElementById("txt2").value;
            window.returnValue = s;
            window.close();
        }
</script>
</head>
<body>
    <form name="abc" runat="server">
          <input type="text" id="txt1" name="txt1"/>
       <input type="text" id="txt2" name="txt2"/>
        <input type="button" id="btn1" name="btn1" value="提交" onclick="setFather()" />
</form>
</body>
</html>
