摘要:[VB] ASP.NET 使用 JavaScript 開新視窗跨網頁回傳資料方法
前言
在專案中開新視窗顯示資料是蠻常用到的功能，延伸而來就會有需要將新視窗的資料帶回主視窗的情況，
新視窗回傳值的方法可以參考以下範例。
範例
Step 1
主視窗頁面:
<head runat="server">
<title></title>
<script src="Scripts/jquery-1.8.3.min.js" type="text/javascript"></script>
<script type="text/javascript">
$(function () {
$("#Button1").click(function () {
window.open('SubMain.aspx?SrcCtl=TextBox1&SrcForm=form1&SrcType=1',
'NewWindows',
'height=230,width=120px,status=no,toolbar=no,menubar=no,location=no,top=150,left=150);');
return false;
});
$("#Button2").click(function () {
window.open('SubMain.aspx?SrcCtl=TextBox1&SrcForm=form1&SrcType=2',
'NewWindows',
'height=230,width=120px,status=no,toolbar=no,menubar=no,location=no,top=150,left=150);');
return false;
});
$("#Button3").click(function () {
window.open('SubMain.aspx?SrcCtl=TextBox1&SrcForm=form1&SrcType=3',
'NewWindows',
'height=230,width=120px,status=no,toolbar=no,menubar=no,location=no,top=150,left=150);');
return false;
});
});
</script>
</head>
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" AutoPostBack="True"
ontextchanged="TextBox1_TextChanged"></asp:TextBox>
<br />
<asp:Button ID="Button1" runat="server" Text="開新視窗帶回值" />
<asp:Button ID="Button2" runat="server" Text="開新視窗帶回值並重Load畫面" />
<asp:Button ID="Button3" runat="server" Text="開新視窗帶回值並PostBack畫面" />
<br />
<asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
</div>
</form>
</body>
主視窗的 Script Url 參數說明:
- SrcCtl: 之後要接收回傳值的 Control Client ID
- SrcForm: 本頁的Form ID
- SrcType: 子頁面接收判斷的參數，真正使用上可以不用
Step 2
子視窗程式碼:
public partial class SubMain : System.Web.UI.Page
{
string srcCtl = "";
string srcForm = "";
string srcType = "";
protected void Page_Load(object sender, EventArgs e)
{
srcCtl = Request.Params["SrcCtl"];
srcForm = Request.Params["SrcForm"];
srcType = Request.Params["SrcType"];
}
protected void Button1_Click(object sender, EventArgs e)
{
ReturnOpener();
}
public void ReturnOpener()
{
string jsStr = "";
switch (srcType)
{
case "1":
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = ";
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = form1." + TextBox1.ClientID + ".value; ";
jsStr += "window.close();";
ClientScript.RegisterStartupScript(this.GetType(), "ret", jsStr, true);
break;
case "2":
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = ";
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = form1." + TextBox1.ClientID + ".value; ";
jsStr += "window.close();";
jsStr += "self.opener.location.reload();";
ClientScript.RegisterStartupScript(this.GetType(), "ret", jsStr, true);
break;
case "3":
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = ";
jsStr += "window.opener." + srcForm + "." + srcCtl + ".value = form1." + TextBox1.ClientID + ".value; ";
jsStr += "window.close();";
jsStr += "self.opener." + srcForm + ".submit();";
ClientScript.RegisterStartupScript(this.GetType(), "ret", jsStr, true);
break;
default:
break;
}
}
}子視窗說明:
當接收到主視窗URL時將參數取得 ，當子視窗按鈕觸發時註冊JavaScript關閉本頁將參數帶回主頁。
