将类添加到正则表达式jQuery [英] add class to regex jquery

问题描述

我有这个

if( window.location.href == "http://localhost:3000/categories") {
     $("#container ul #all_categories a.categories-menu").css("font-weight","bold");
    }   
});

但是我有一个网址:

http://localhost:3000/username/boards

用户名是动态用户名，例如

http://localhost:3000/michael-21/boards
http://localhost:3000/Richard_10/boards
http://localhost:3000/Mary.50/boards

并为每个用户进行更改.

and change for each user.

如何使用最后一个URL来实现相同的功能?

How can do the same functionality but with this last url?

谢谢

推荐答案

您不需要RegEx.以下方法更容易维护，也更容易维护(将页面移至生产环境时无需更改代码中的URL):

You don't need a RegEx. The following method is easier, and is also easier to maintain (you don't have to change the URL in the code when moving the page to the production environment):

location.pathname.indexOf('/boards', 1) !== -1

上一个也将匹配/me/not/boards.如果您不希望这样做:

The previous would also match /me/not/boards. If you don't want that:

var index = location.pathname.indexOf('/boards', 1);
index !== -1 && location.pathname.lastIndexOf('/', index-1) === 0

最后，RegEx方法:

Finally, the RegEx method:

/^\/[^/]+\/boards/.test(location.pathname)

实施示例

    if( /^\/[^/]+\/boards/.test(location.pathname) ) {
         $("#container ul #all_categories a.categories-menu").css("font-weight","bold");
    }   
});
