Current page: It's possible to do even shorter. This single line sound more elegant to find the current page's file name:

当前页面：可以做得更短。用这一行来查找当前页面的文件名听起来更优雅：

var fileName = location.href.split("/").slice(-1); 

or...

或者...

var fileName = location.pathname.split("/").slice(-1)

This is cool to customize nav box's link, so the link toward the current is enlighten by a CSS class.

自定义导航框的链接很酷，因此指向当前的链接由 CSS 类启发。

JS:

JS：

$('.menu a').each(function() {
    if ($(this).attr('href') == location.href.split("/").slice(-1)){ $(this).addClass('curent_page'); }
});

CSS:

CSS：

a.current_page { font-size: 2em; color: red; }

Try this

尝试这个

location.pathname.substring(location.pathname.lastIndexOf("/") + 1);

location.pathname gives the part(domain not included) of the page url. To get only the filename you have to extaract it using substring method.

location.pathname 给出页面 url 的部分（不包括域）。要仅获取文件名，您必须使用子字符串方法提取它。

Use: location.pathname

用： location.pathname

alert(location.pathname);

Use window.location.pathnameto get the path of the current page's URL.

使用window.location.pathname来获取当前页面的URL路径。

This will work even if the url ends with a /:

即使 url 以 结尾，这也会起作用/：

var segments = window.location.pathname.split('/');
var toDelete = [];
for (var i = 0; i < segments.length; i++) {
    if (segments[i].length < 1) {
        toDelete.push(i);
    }
}
for (var i = 0; i < toDelete.length; i++) {
    segments.splice(i, 1);
}
var filename = segments[segments.length - 1];
console.log(filename);

Single statement that works with trailing slash. If you are using IE11 you'll have to polyfillthe filterfunction.

与尾随斜杠一起使用的单个语句。如果您使用的是 IE11，则必须对函数进行polyfillfilter。

var name = window.location.pathname
        .split("/")
        .filter(function (c) { return c.length;})
        .pop();
