这里是低于

<html> 
    <head> 
     <title>Animate Files</title>

      img0.src="img/Mouth-m.jpg"; 

      var img1 = new Image(640, 960);

      function animate() { 
       document.images[0].src = eval("img" + i).src; 
       i++; 
       if(i == nbImg) i=4; 
       junk = setTimeout("animate();", 300); 
      }

列出的代码没有测试过这一点，但试一试：

<!DOCTYPE html> 
<html> 
<head> 
<title>Animate Files</title> 
<script type="text/javascript"> 
    var img0 = new Image(640, 960); 
    img0.src="img/Mouth-m.jpg"; 

    var img1 = new Image(640, 960); 
    img1.src="img/Mouth-o.jpg"; 

    var img2 = new Image(640, 960); 
    img2.src="img/Mouth-s.jpg"; 

    var img3 = new Image(640, 960); 
    img3.src="img/Mouth-e.jpg"; 

    var img4 = new Image(640, 960); 
    img4.src="img/Mouth-m.jpg"; 

    var hiatus; 

    function animate(i) { 
     clearTimeout(hiatus); 

     document.images[0].src = window['img' + i].src; 

     if(i === 4) { 
      return; 
     } 

     hiatus = setTimeout(function() { 
      animate(i + 1); 
     }, 300); 
    } 
</script> 
</head> 
<body> 
    <img src="img/Mouth-m.jpg" width="640" height="960"/> 
    <button type="button" onclick="animate(0)">One</button> 
</body> 
</html>
