RegisterStartupScript不起作用，这表示更新面板无法在asp.net的新选项卡中打开文件 [英] RegisterStartupScript not working indise an Update Panel to open file in new tab in asp.net

问题描述

我正在尝试使用更新面板中的ScriptManager.RegisterStartupScript在新选项卡中打开文件，但无法正常工作.代码如下:

I am trying to open a file in new tab using ScriptManager.RegisterStartupScript inside update panel, but its not working. The Code is as below :

filename = Server.UrlEncode(filename);
     string js = "<script>window.open('ViewReports.aspx?filename=" + Server.UrlEncode(filename) + "', '_newtab');</script>";
     ScriptManager.RegisterStartupScript(UpdatePanel1,UpdatePanel1.GetType(),"Pop up",js,true);

这也行不通:

This also not working:

ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), js, true);

当我在更新面板之外使用下面的代码时，它可以正常工作:

And when I am using below code outside Update Panel it works:

 Type cstype = this.GetType();

ClientScriptManager cs = Page.ClientScript;
cs.RegisterStartupScript(cstype, "dateSrpt", "<script>window.open('ViewReports.aspx?filename=" + Server.UrlEncode(filename) + "', '_newtab');</script>");

推荐答案

制作一个javascript函数以使用Window.Open()打开文件，然后从服务器端调用该函数...

Make a javascript function to open a file using Window.Open(), and call the function from server side...

protected void Button1_Click(object sender, EventArgs e)
   {
       string js = "javascript:openFile('http://localhost:58237/WebSite14/textfile.txt')";
       ScriptManager.RegisterStartupScript(this, this.GetType(), "Pop up", js, true);

   }

我假设此代码位于Button_Click中，并且按钮位于Updatepanel内...

I Assumed this code is placed in a Button_Click and the button is inside Updatepanel...

<asp:UpdatePanel ID="upnl" runat="server">

   <ContentTemplate>
       <asp:Button ID="Button1" runat="server" Text="Open File" onclick="Button1_Click"  />

   </ContentTemplate>
   </asp:UpdatePanel>

javascript函数如下:

the javascript function is as follows:

<script>
       function openFile(fileName) {
           window.open(fileName, '_blank');
       }
   </script>

如果您确实正在寻找它，它就可以正常工作.
编码愉快

it works fine if you are exactly looking for this..
Happy coding
