!!!aspx文件之间参数传输问题，高分求助！!!

ywcyj 2003-07-01 02:02:31

有两个文件：test1.aspx，test2.aspx
1、点击test1.aspx的Button1，弹出test2.aspx页面，并将test1.aspx中a，b的值传给test2.aspx。
2、点击test2.aspx的Button2，将test2.aspx中c的值返回给test1.aspx，关闭test2.aspx页面
第一步已经完成，代码如下：
test1.aspx
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a As Single
Dim b As Single
a = 1
b = 2
Dim sURL As String
Dim strItem As String
sURL = "test2.aspx?a=" + a.ToString + "&b=" + b.ToString
strItem = "<script language=JavaScript>window.open('" + sURL + "','', 'height=500, width=500, toolbar=no, menubar=no, scrollbars=no, resizable=no, location=no, status=no');</script>"
Response.Write(strItem)
End Sub
test2.aspx
Dim a As Single
Dim b As Single
a = Page.Request("a")
b = Page.Request("b")
TextBox1.Text = a.ToString
TextBox2.Text = b.ToString

第二步咋写？
哪位帮我提供一段代码吧
谢了先

要求:
1、点击test3.aspx的Button1，读取TextBox1的值,赋给a,弹出test4.aspx，将a值传给test4.aspx。
2、点击test4.aspx的Button1，将计算(+100)所得的b值返回给test1.aspx，关闭test2.aspx。
3、test1.aspx获得b值后,将其赋给TextBox1,自动更新,在页面上显示出来。
代码如下:
test3.aspx:

Protected WithEvents Button1 As System.Web.UI.WebControls.Button
Protected WithEvents TextBox1 As System.Web.UI.WebControls.TextBox
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim a As Single = CSng(TextBox1.Text) 'TextBox1.Text为10
Dim sURL As String
Dim strItem As String
sURL = "test4.aspx?a=" + a.ToString
strItem = "<script language=JavaScript>window.showModalDialog('" + sURL + "','', 'dialogHeight: 200px; dialogWidth: 150px; dialogTop: 458px; dialogLeft: 166px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;');</script>"
Response.Write(strItem)
End Sub

test4.aspx:

Protected WithEvents Button1 As System.Web.UI.WebControls.Button
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim b As Single
b = Request.QueryString("a")
b += 100
Response.Write("<script language=JavaScript>window.returnValue = b.ToString();window.close();</script>")
End Sub

说明:test4.aspx已经添加<base target="_self">,但还是一提交就重新打开一个页面
第一次用模态窗口,不会.
各位高手帮我写完整吧!谢了先

1.window.showModalDialog("DialogPage.aspx","newwin","dialogHeight: 200px; dialogWidth: 150px; dialogTop: 458px; dialogLeft: 166px; edge: Raised; center: Yes; help: Yes; resizable: Yes; status: Yes;");

2.window.close();

3.传值
ParentPage.aspx:
window.showModalDialog("DialogPage.aspx?para1=aaa¶2=bbb");

DialogPage.aspx:
string str1=Request.QueryString["para1"].toString();
string str2=Request.QueryString["para2"].toString();

返回值
DialogPage.aspx:
window.returnValue="aaa";

ParentPage.aspx:
var str=window.showModalDialog("DialogPage.aspx");

4.
aspx页面在showmodeldialog情况下为什么一提交就重新打开一个页面?
showmodaldialog打开的页面中在<head></head>之间加入一行：<base target="_self">

参数值回传是吧。看看原来的asp与jacascript写的你就会明白了，不用那么麻烦。我没时间所以不帮你写了，你先看看

//第一个文件
<form name=auth_form method=post><input type=hidden name=userInfo value=''></form><script>
var temp=new Array();
temp[0]='default.htm';
temp[1]='loginBsSystem';///Maintenance';
temp[2]='0';
temp[3]='';

var userInfo;
var undefined;
var ll=(screen.width-400)/2;
var tt=(screen.height-210)/2;

userInfo=window.showModalDialog ('login.asp',temp,'dialogHeight:210px;dialogWidth:400px;dialogTop:' + tt +';dialogLeft:' + ll + 'px;status:no;scroll:no');
if(userInfo==undefined)
{
window.open('error/errorCancel.html','_top','');
}
else
{
auth_form.action='loginBsSystem/check.asp';
auth_form.userInfo.value=userInfo;
auth_form.submit();
}
</script>

//========下面为第二个文件

<SCRIPT>
var back=new Array()
back=window.dialogArguments

if(back[3] != "") window.alert(back[3])
function on_submit()
{
window.returnValue=myform.username.value+"-"+myform.password.value+"-"+back[0]+"-"+back[1]+"-"+back[2]
self.close()
}
</SCRIPT>

在A页面中用JAVASCRIPT弹出B页面
Response.Write("<script Language=JavaScript>");
string url="B.aspx
Response.Write("ChildWindow = window.open('"+url+"', '111', 'width=220,height=200,top=180,left=280,toolbar=no,status=yes,location=no,menubar=no,directories=no,scrollbars=no,resizable=no')");
Response.Write("</script>");
在B页面中用JAVASCRIPT回传参数
Response.Write("<script Language=JavaScript>");
Response.Write("window.opener.document.forms['newmessage'].elements['Return'].value ='"你要回传的STRING"';");
Response.Write("window.close();");
Response.Write("</script>");

Return是A页面中的TEXTBOX 的ID，newmessage是A页面
