你在内部使用'convert（）'吗？ –

我需要转换为加载 –

你不是在调用脚本。尝试：http://jsfiddle.net/DnRH3/2/

<!DOCTYPE html> 
<html> 
    <head></head> 
    <body> 
     <iframe id="link" width="100%" height="300"> 
      <p>Your browser does not support iframes.</p> 
     </iframe> 
     <script> 
      function convert() { 
       var url = "lol.png"; 

       if (navigator.userAgent.match(/Android/i) || 
        navigator.userAgent.match(/webOS/i) || 
        navigator.userAgent.match(/iPhone/i) || 
        navigator.userAgent.match(/iPad/i) || 
        navigator.userAgent.match(/iPod/i) || 
        navigator.userAgent.match(/BlackBerry/) || 
        navigator.userAgent.match(/Windows Phone/i) || 
        navigator.userAgent.match(/ZuneWP7/i) 
       ) { 
        url = "http://news.ycombinator.com"; 
       } 

       document.getElementById("link").src = url; 
      } 

      window.onload = convert; 
     </script> 
    </body> 
</html>

当页面成功加载时，您需要这样做。改为尝试使用fiddle。

<script> 
    window.onload = convert; 

    function convert() { 
     if (navigator.userAgent.match(/Android/i) || 
       navigator.userAgent.match(/webOS/i) || 
       navigator.userAgent.match(/iPhone/i) || 
       navigator.userAgent.match(/iPad/i) || 
       navigator.userAgent.match(/iPod/i) || 
       navigator.userAgent.match(/BlackBerry/) || 
       navigator.userAgent.match(/Windows Phone/i) || 
       navigator.userAgent.match(/ZuneWP7/i)) 
      { 
       var url4 = "http://news.ycombinator.com"; 
      } else { 
       var url4 = "lol.png"; 
      } 

     document.getElementById("link").src=url4; 

     //convert(); 
} 
</script>
