我比较喜欢看电影,所以会经常去百度电影票房吧看帖子,但是有些人不知道出于什么目的,在每个帖子中都会发布同样的内容,严重干扰正常的看帖,如果下面这位:
每个帖子都能看到它,心里很不爽,发条呼吁版主封账号,没有用。
刚好最近看了一点javascript的东西,突然就想做个扩展,屏蔽这种帖子,眼不见为净。
主要工作原理如下:
1、用户在设置界面输入想屏蔽的用户ID,通过后台JS脚本存储到本地;
2、当打开贴吧的帖子时,通过 这句获得用户帖子内容:var lstdiv = document.getElementsByClassName("l_post l_post_bright ");,如果用户ID刚好在被屏蔽的人中,那么把此DIV innerhtml设置为空;
想上传到扩展商店呢,结果发现要5刀。
