Question

我无法获取window.opener值以在子弹出窗口之间传输。此代码适用于IE 8和订单，但退出IE 9及更高版本。任何输入都表示赞赏。

用不同的方式解释。我妹妹知道我是她的兄弟，但不相信我告诉她我们的父母是谁。

流程：
父窗口（主窗体） - ＆gt;打开弹出窗口（PopUp 1）
用户单击PopUp 1上的按钮以打开PopUp 2 PopUp 2打开：
它从PopUp 1中提取数据然后关闭PopUp 1
用户单击PopUp 2上的按钮（保存）。
PopUp 2刷新原始父“主窗体”上的数据。然后关闭自己。

最后一步是没有讨厌IE 9的步骤。我创建了下面的示例，以显示使用纯JavaScript的功能，但在回发和使用RegisterStartupScript调用JavaScript函数时失败。我们正在使用RegisterStartupScript，因为表单的保存操作根据用户的输入有许多不同的结果。
所有页面都在同一个域中。

        If Not Page.IsPostBack() Then
            ClientScript.RegisterStartupScript(Type.GetType("System.String"), "Refresh", _
                    "<script type=""text/javascript"">GrabData();</script>")

            "<script type=""text/javascript"">MyClose();</script>", False)
    End Sub
End Class

Answer 1

不应该这样：

Protected Sub btnSave_Click(sender As Object, e As System.EventArgs) Handles btnSave.Click
    ScriptManager.RegisterStartupScript(Me, Me.form1.GetType(), "RestoreFilter", _
        "<script type=""text/javascript"">MyClose();</script>", False)
End Sub

Be（参见GetType部分）：

Protected Sub btnSave_Click(sender As Object, e As System.EventArgs) Handles btnSave.Click
    ScriptManager.RegisterStartupScript(Me, Me.GetType(), "RestoreFilter", _
        "<script type=""text/javascript"">MyClose();</script>", False)
End Sub

RegisterStartupScript使window.opener为null
