从路径中提取URL的目录，而不使用诸如"index.html"之类的文件名. [英] Extract URL's directory from path, without file name such as "index.html"

问题描述

我正在寻找普通的JavaScript代码(没有jQuery等)来学习当前加载页面的URL的目录路径部分.

I am looking for plain JavaScript code (no jQuery etc.) to learn the directory path component of my currently loaded page's URL.

例如，如果我的页面加载为" http://localhost/myapp/index.html "，我想以" http://localhost/myapp/结尾.

For instance, if my page is loaded as "http://localhost/myapp/index.html", I like to end up with "http://localhost/myapp/".

我需要这样做，以便在同一位置创建指向其他文件的路径，例如到" http://localhost/myapp/other.html ".

I need this in order to create the path to a different file in the same location, e.g. to "http://localhost/myapp/other.html".

推荐答案

看起来像这样:

var href = window.location.href;
var dir = href.substring(0, href.lastIndexOf('/')) + "/";

这是一种安全的方法，还是会因为使用更复杂的URL而失败?

Is this a safe method or can this fail with more complex URLs?
