我怎样才能得到 Javascript 中的工作目录名称？

我尝试用 Javascript 获取文件的工作目录，这样我就可以用它为我网站的每个部分触发一个不同的 jquery 函数。

if (current_directory) = "example" {
var activeicon = ".icon_one span";
};
elseif (current_directory) = "example2" {
var activeicon = ".icon_two span";
};
else {
var activeicon = ".icon_default span";
};


$(activeicon).show();
...

有什么想法吗？

Assuming you are talking about the current URL, you can parse out part of the URL using window.location. See: http://java-programming.suite101.com/article.cfm/how_to_get_url_parts_in_javascript

window.location.pathname

You can use window.location.pathname.split('/');

That will produce an array with all of the items between the /'s

This will work for actual paths on the file system if you're not talking the URL string.

var path = document.location.pathname;
var directory = path.substring(path.indexOf('/'), path.lastIndexOf('/'));

window.location.pathname will get you the directory, as well as the page name. You could then use .substring() to get the directory:

var loc = window.location.pathname;
var dir = loc.substring(0, loc.lastIndexOf('/'));

Hope this helps!

For both / and \:

window.location.pathname.replace(/[^\\\/]*$/, '');

To return without the trailing slash, do:

window.location.pathname.replace(/[\\\/][^\\\/]*$/, '');

complete URL

If you want the complete URL e.g. http://website/basedirectory/workingdirectory/ use:

var location = window.location.href;
var directoryPath = location.substring(0, location.lastIndexOf("/")+1);

local path

If you want the local path without domain e.g. /basedirectory/workingdirectory/ use:

var location = window.location.pathname;
var directoryPath = location.substring(0, location.lastIndexOf("/")+1);

In case you don't need the slash at the end, remove the +1 after location.lastIndexOf("/")+1.

directory name

If you only want the current directory name, where the script is running in, e.g. workingdirectory use:

var location = window.location.pathname;
var path = location.substring(0, location.lastIndexOf("/"));
var directoryName = path.substring(path.lastIndexOf("/")+1);
小开

This one-liner works:

var currentDirectory = window.location.pathname.split('/').slice(0, -1).join('/')
小开

In Node.js, you could use:

console.log('Current directory: ' + process.cwd());
小开

If you want the complete URL e.g. website.com/workingdirectory/ use: window.location.hostname+window.location.pathname.replace(/[^\\\/]*$/, '');

An interesting approach to get the dirname of the current URL is to make use of your browser's built-in path resolution. You can do that by:

  1. Create a link to ., i.e. the current directory
  2. Use the HTMLAnchorElement interface of the link to get the resolved URL or path equivalent to ..

Here's one line of code that does just that:

Object.assign(document.createElement('a'), {href: '.'}).pathname

In contrast to some of the other solutions presented here, the result of this method will always have a trailing slash. E.g. running it on this page will yield /questions/3151436/, running it on https://stackoverflow.com/ will yield /.

It's also easy to get the full URL instead of the path. Just read the href property instead of pathname.

Finally, this approach should work in even the most ancient browsers if you don't use Object.assign:

function getCurrentDir () {
var link = document.createElement('a');
link.href = '.';
return link.pathname;
}
