[导入][原创]使用正则表达式找出HTML代码内所有IMG图片的SRC链接地址

最新的 getImg() 函数可以提取HTML代码内的全部的图片地址。

getImg() 函数地址: http://jorkin.reallydo.com/article.asp?id=448。

如发现其它BUG请在下面的评论中反馈给我.

目前可以通过以下各种常见的代码障碍(单引号,双引号,脚本,样式...)

<img id=img src="/images/reallydo.jpg">
<img id=img src=/images/reallydo.jpg/> 后来证明这句是错误的HTML,图片不能正常显示.
<img id=img src=/images/reallydo.jpg />
<img id=gif src=http://jorkin.reallydo.com/images/reallydo.gif />
<img id=img src="/images/reall ydo.bmp" class=go> (图片名称有空格)
<img id=img src="/images/reallydo.jpg" class=go/>
<img id=jpg src="/images.gif/reallydo.jpg" class=go />

<img id=img src=http://www.reallydo.com/images/reallydo.jpg onclick='<' class='go' />
