QQ IP显示的关键代码

qiuyi21 2021-08-15 原文

这是LiteIM/FreePlus的取IP代码,感兴趣的朋友看看吧.
runjin的是汇编版本,这是c版本,希望有更多的人能读懂.后来者,愿它对你有益.闪了.

INPUT { behavior: url(http://localhost:81/blog/admin/FCKeditor/editor/css/behaviors/hiddenfield.htc) }
TABLE { behavior: url(http://localhost:81/blog/admin/FCKeditor/editor/css/behaviors/showtableborders.htc) }
INPUT, TEXTAREA, SELECT, .FCK__Anchor, .FCK__PageBreak { behavior: url(http://localhost:81/blog/admin/FCKeditor/editor/css/behaviors/disablehandles.htc) }
