Question

我正在使用JavaScript将一个值从对话框传递到asp父页面的简单示例/快速修复 - 如果java脚本是最好的选项！

我已经多次尝试这样做，但到目前为止每次努力都失败了。

lblVarSelectedDate.Text是我想回发到父页面的值，显示为lblVarChildSelectedDate值。

以下是Register.aspx页面（PARENT）的一部分

    <table>
<tr>
      <td colspan="5" align="center"><asp:Label ID="lblDate" runat="server" Text="Selected Date: "></asp:Label><asp:Label ID="lblVarChildSelectedDate" runat="server" ></asp:Label></td>
      <td colspan="1" align="center"><asp:Button ID="btnSelectDate" runat="server" Text="Date" /> </td>
</tr
<tr>
    <td><asp:Button ID="btOK" runat="server" Text="Ok" /> </td>
</tr>
</table>

这是寄存器后面的VB.aspx ...

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load


End Sub

Sub btnSelectDate_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnSelectDate.Click

    Dim Window As String
    Window = " window.open('About.aspx', 'MsgWindow', 'width=500, height=500');"

    ClientScript.RegisterClientScriptBlock(Me.GetType, "date", Window, true)


End Sub

Sub btnOk_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btOK.Click

End Sub

现在她是我的子页面selectdate.aspx ..

    <table>
<tr>
    <td colspan="6"><asp:Calendar ID="calSelecter" runat="server" OnSelectionChanged="SelectionChange"></asp:Calendar></td>

</tr>
<tr>
      <td colspan="6" align="center"><asp:Label ID="lblConsSelectedDate" runat="server" Text="Selected Date: "></asp:Label><asp:Label ID="lblVarSelectedDate" runat="server" ></asp:Label></td>
</tr
<tr>
    <td><asp:Button ID="btOK" runat="server" Text="Ok" /> </td>
</tr>
</table>

她是儿童页面背后的vb。

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load

    calSelecter.SelectedDate = Date.Today
    lblVarSelectedDate.Text = Date.Today

End Sub

Sub btnOk_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btOK.Click

    ' .... on click post back to parent page lblVarSelectedDate.Text 

End Sub

Sub SelectionChange(ByVal sender As Object, ByVal e As EventArgs)

    lblVarSelectedDate.Text = calSelecter.SelectedDate

End Sub

非常感谢

一种方法如下：

在父级中，在页面中创建一个包含数据的元素
打开模态时，将引用传递给父
在模式中使用对父页面的引用来访问第一步中的元素并将数据保存在该元素中

从模态对话框将值传递给父级
