ASP.NET的WebForms回发+然后打开弹出 [英] ASP.NET WebForms + Postback then open popup

问题描述

我有了回发执行一些逻辑，一个LinkBut​​ton。

I have a LinkButton that has to postback to perform some logic.

一旦完成，而不是在浏览器加载页面的备份，我想息事宁人，弹出打开一个新窗口。

Once it is finished, instead of loading the page back up in the browser, I want to leave it alone and pop open a new window.

到目前为止，我有最好的办法是把LinkBut​​ton的在一个UpdatePanel，并将它呈现一些JavaScript出来时，它重新加载，但我认为这是完全哈克。另外，如果我记得没错，一个更新面板内的JavaScript将无法运行反正

So far, the best idea I've had is to put the LinkButton in an UpdatePanel, and have it render some JavaScript out when it reloads, yet I think that is totally hacky. Also, if I recall right, JavaScript within a update panel won't run anyways.

任何其他的想法？

推荐答案

使用LinkBut​​ton.PostBackUrl设置不同的页面张贴到，有的客户端脚本来获得一个新的窗口（和恢复，以便将来回传工作的老目标一般）。第2页可以使用previousPage摆脱原来的页面访问任何所需的状态。

Use LinkButton.PostBackUrl to set a different page to POST to, and some client script to get a new window (and the old target restored so that future postbacks work normally). The 2nd page can use PreviousPage to get access to any needed state from the original page.

<script runat="server">
   void lnk_Click(object sender, EventArgs e) {
      // Do work
   }
</script>

<script type="text/javascript">
   var oldTarget, oldAction;
   function newWindowClick(target) {
      var form = document.forms[0];
      oldTarget = form.target;
      oldAction = form.action;
      form.target = target;

      window.setTimeout(
         "document.forms[0].target=oldTarget;"
         + "document.forms[0].action=oldAction;", 
         200
      );
   }
</script>

<asp:LinkButton runat="server" PostBackUrl="Details.aspx" Text="Click Me"
  OnClick="lnk_Click"
  OnClientClick="newWindowClick('details');" />
