c#後臺調用前臺js關閉已打開的窗口

前臺：一定要有form標籤，否則this.ClientScript.RegisterStartupScript();無效

<script src="../js/jquery-1.9.1.min.js"></script>

 <script>
        function closeLayer() {
           
              var index = parent.layer.getFrameIndex(window.name); //獲取窗口索引
              parent.layer.close(index); //關閉窗口

          }
    </script>

<form id="form1" runat="server">

......

</form>

後臺：

this.ClientScript.RegisterStartupScript(ClientScript.GetType(), "myscript", "<script>closeLayer();</script>");
