VB.net 使用Response.write()+opner和document.getElementById('TB_Linshi').value 实现子窗口值传回父窗口，传不回数值，但可以传回固定值'123'，

1. 在父窗口点击BT_WO弹出子窗口，子窗口有TB_Lishi和Gridview1，Gridview1设置了AutoGenerateSelectButton="True"，通过点击"选择"触心GridviewSelectedIndexChanged事件，将"选择"的行的值赋予给子页面的TB_Lishi，然后通过如下 语句：Response.Write("window.opener.document.getElementById('TB_WO').value=window.document.getElementById('TB_Linshi').ID")，却始终传不到数据，而采用Response.Write("window.opener.document.getElementById('TB_WO').value='123'")却可以传回，折腾好久，搞不明白

2. 完整代码片段如下

    Protected Sub GridView1_SelectedIndexChanged(sender As Object, e As EventArgs) Handles GridView1.SelectedIndexChanged

        TB_Linshi.Text = Me.GridView1.SelectedRow.Cells(1).Text.ToString()

        Response.Write("<script>window.opener.document.getElementById('TB_WO').value=window.document.getElementById('TB_Linshi').ID</script>")



        '//直接关闭页面，无需点击确认按纽  document.getElementById('TB_Linshi').value
        Response.Write("<script>window.close();value='确定'</script>")

    End Sub
