JS遍历IMG

<p>你好.<img height="10" width="12" alt="" src="/Upload/image/2009-8-19/2009819135229.jpg" />你好<img height="808" width="20" alt="" src="/Upload/image/2009-8-19/2009819135248.jpg" /></p>以上数据是从数据库提取出来的,我要用JS遍历出里面所有的图片路径,也就是"/Upload/image/2009-8-19/2009819135229.jpg"和"/Upload/image/2009-8-19/2009819135248.jpg",请问怎么实现,谢谢.

思路获取 a = 某个容器对象下.getElementsByTagName('img')
var source = a.getAttribute('src');
for(var i=0;i<a.length;i++){
  document.writeln(a[i].source);}
刚才的有点问题给你简单写了一个参考下吧

       alert(arr[3]);
