如何设置html链接< a href>动态使用C＃ [英] How to set html link <a href> dynamically using C#

问题描述

 < div> 
< ul> 
< li>< a href =http：// localhost：52451 / Voronezh / Settings.aspx>设置< / a< / li> 
< li>< a href =http：// localhost：52451 / LoginPages / Welcome.aspx>注销< / a< / li> 
< / ul> 
< / div> 
  

我想在某些特殊情况下动态设置这些href链接。

我试过以下内容：

HTML代码

 < li>< a runat =serverid =toSettingsonserverclick =toSettings_ServerClick>设置< / a>< / li> 
  

代码

  protected void toSettings_ServerClick（object sender，EventArgs e）
 {
 if（condition）
 toSettings.HRef =http：// localhost：52451 / Voronezh / Settings.aspx ; 
 else 
 {...} 
} 
  

但它不起作用：我停留在同一页面上，而不是移动到设置页面。

哪里出错？应该改变什么？

预先感谢。

解决方案

更改 HRef 在这里没有多大作用 - 它改变了链接，它对页面没有任何直接影响。尝试 Response.Redirect ，我认为这是你正在寻找的。 I.e：

  // if语句中
 Response.Redirect（Settings.aspx）; //注意 - 这是本地路径
  

I have a menu in my web application like this

<div>
  <ul>
    <li><a href="http://localhost:52451/Voronezh/Settings.aspx">Settings</a</li>
    <li><a href="http://localhost:52451/LoginPages/Welcome.aspx">Log out</a</li>
  </ul>
</div>

I would like to set these href links dynamically if some special condition is true.

I've tried the following:

HTML code

<li><a runat="server" id="toSettings" onserverclick="toSettings_ServerClick">Settings</a></li>

C# code

protected void toSettings_ServerClick(object sender, EventArgs e)
    {
       if (condition)
         toSettings.HRef = "http://localhost:52451/Voronezh/Settings.aspx"; 
       else
         {...}      
    }

but it doesn't work: I stay on the same page instead of moving to the Settings page.

Where is a mistake? What should be changed?

Thanks in advance.

解决方案

Changing the HRef won't do much here - it changes the link, it doesn't have any direct effect on the page. Try Response.Redirect, I think this is what you're looking for. I.e:

// inside the if statement
Response.Redirect("Settings.aspx"); // note - this is the local path
