javascript条件不起作用 [英] javascript condition is not working

问题描述

function IP()
        {
          var net = new ActiveXObject("wscript.network");
          
         if((net.ComputerName).value="")
         {
          window.location.href="Welcome.aspx";
         return true;
         }
         else
         {
alert(net.UserDomain+': '+net.ComputerName);
         alert('SUCCESS')
         return true;
         }
        return false;
       }

推荐答案

很可能是与浏览器安全相关的问题.由于您不能依赖客户端，因此我将在服务器端实现此重定向.看来您处于域环境中，因此您可以轻松地在服务器端检查计算机是否为域成员.

但是您可以将其简单地放在try catch块中，如下所示:

It is very likely to be a browser security related issue. Since yo can not rely on the client I would implement this redirection on server side. It looks that you are in a domain environment, thus you can easily check on server side if the computer is domain member or not.

But you can put it simply in a try catch block, like this:

function IP()
        {
         try
         { 
            var net = new ActiveXObject("wscript.network");
            alert(net.UserDomain+': '+net.ComputerName);
            alert('SUCCESS');
         }
         catch ()
         {
            window.location.href="Welcome.aspx";
            return true;
         } 
        return false;
       }

function IP()
        {
          var net = new ActiveXObject("wscript.network");

         if((net.ComputerName).value="")
         {
          window.location.href="Welcome.aspx";
         return true;
         }
         else
         {
alert(net.UserDomain+': '+net.ComputerName);
         alert('SUCCESS')
         return true;
         }
      //  return false;     dont use
       }

我尝试了这个

i tried this

try
        {
           var net = new ActiveXObject("wscript.network");
           alert(net.UserDomain+': '+net.ComputerName);
           alert('SUCCESS');
        }
        catch(err)

        {
           window.location.href="Welcome.aspx";
        }

成功
