如何使用JavaScript修改网站标题? [英] How can I modify the title of a site using JavaScript?
问题描述
查看torrent页面时,选项卡的标题为:
When viewing a torrent page, the title of the tab is:
Bitsoup.org激流食欲的最佳网站::的详细信息 种子"ABC"
Bitsoup.org The Best site for your Torrent appetite :: Details for torrent "ABC"
其中"ABC"是种子文件的名称.
where "ABC" is the name of the torrent file.
不幸的是,当我打开3个以上的选项卡时,看不到种子文件的名称.
Unfortunately, when I have 3+ tabs open, I can not see what the name of the torrent file is.
我正在尝试创建一个Greasemonkey脚本来截断或拆分标题,以使其仅显示种子名称,而不显示开头部分.
I am attempting to create a Greasemonkey script to truncate, or split, the title, so that it only displays the torrent-name, and not the beginning part.
我知道您可以使用document.title = ...
但我不确定将其分配给什么.
but I am unsure of what to assign it to.
推荐答案
您可以使用正则表达式,也许:
You could use a regular expression, perhaps:
document.title = document.title.match(/"([^"]+)"/)[1]
此正则表达式使用分组来匹配引号之间的第一项内容,并将其分配给title
(不带引号).
This regex uses grouping to matches the first thing that is between quotes, and assigns it to the title
(without the quotes).
