我只需要一个jQuery片段来完成img src中的前置,即

<img src='/img/picture1.jpg' />

代码片段jQuery将预先添加此url

http://cdn.something.com/

<img src='http://cdn.something.com/img/picture1.jpg' />

任何帮助是极大的赞赏.

$().ready(function(){
     var cdn ='http://cdn.something.com';
   $('img').attrib('src', cdn);

});

然而它被替换为src而不是pre
