JavaScript移动重定向问题

Question

Hi this has doing my head in for an hour or so now, I want to redirect my mobile traffic but depending on the GEO to different locations, I have got the redirect script working fine using switch, case but when I add it within an if statement if (screen.width <= 699) for mobile devices its not working and I dont know why. this is what i have

 <script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script>
 <script language="JavaScript">
   var country = geoip_country_code();
   if (screen.width <= 699) {   
   switch (country)
   {
   case (country = "ES"):
     window.location = "http://url1.com";
   break;
   case (country = "US"):
     window.location = "http://url1.com";
   break;

   default:
     window.location = "http://url2.com";
   break;
  }
 }

Just having it like this work fine...

 <script language="JavaScript">
var country = geoip_country_code();
switch (country)
{
case (country = "ES"):
  window.location = "http://url1.com";
break;
case (country = "US"):
  window.location = "http://url1.com";
break;

default:
  window.location = "http://url2.com";
break;
}

thanks in advance to anyone who can help me with this I really appreciate it!

Include the following in your html's header:

<meta name="viewport" content="width=device-width, user-scalable=no" />

So your mobile devices don't resize to "desktop" emulation
