我有一个特定于页面的chrome扩展，我正在开发，它可以对我经常访问的论坛上的页面进行修改。(http://code.google.com/p/orpcastmanagerchromeextension/wiki/About)

我有一种方法可以让人们用特定线程组中的自定义url来替换人们的头像（这些用户是“按角色玩”游戏中的玩家）

论坛将人物头像img设置为宽度=60，高度=60：

<img src="https://urlforSinbadEVsavatar" width="60" height="60" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

并获取一个0x0图像：

<img src="https://urlforSinbadEVsavatar" width="0" height="0" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

<img src="https://urlforSinbadEVsavatar" width="0" height="0" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

<img src="https://urlforSinbadEVsavatar" width="60" height="60" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar" style="width: 100%; height: 100%; ">

并获取一个0x0图像：

<img src="https://urlforSinbadEVsavatar" width="0" height="0" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

<img src="https://urlforSinbadEVsavatar" width="0" height="0" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

<img src="https://urlforSinbadEVsavatar" width="60" height="60" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar" style="width: 100%; height: 100%; ">

并获得1x60图像：

并获得一张60x60的图像：

<img src="https://lh4.googleusercontent.com/-DKJY8ApOJHM/Tt_nTqBCIKI/AAAAAAAAAi0/lGF2J4nLiRo/s60/KindlyDM60x60.png" width="60" height="60" alt="SinbadEV's Avatar" border="0" title="SinbadEV's Avatar">

我想摆脱约束或将其设置为原始大小的100%。我遗漏了什么？

我一直在寻找，最终找到了：

img\u node.removeAttribute（“width”，0）
img_节点。删除属性（“高度”，0）这正是我要找的。。。但我还不能回答我自己的问题。
img_node.removeAttribute("width",0);
img_node.removeAttribute("height",0);
