How to link to the directory above web root by JavaScript?

I'm trying to link to the directory above the web root, but it doesn't work in JavaScript. It doesn't matter how many ../ I use, it doesn't go more than twice, which is required to reach the web root. (Using PHP this works fine, though) I think it should be possible right? Could it be a permission problem? Thanks.

You can't link to a folder above the web root, because it simply doesn't exist.

You link to a web resource, not a physical folder. This resource usually corresponds to a file or folder stored physically on the server, but it doesn't have to. When it does correspond to a file or folder in the file system, it's only folders under the folder corresponding to the web root that is a part of the resources in that web. Anything above the folder is simply not part of the web. Eventhough it exists in the file system, it doesn't exist as a web resource.

Javascript works on the client side. Client side doesn't know anything about the fylesystem of server so can't know or access anything there - client's root is domain name and adding one more '..' means trying to dive above domain name, not above one level in filesystem.

If you want to reach website root name, It's here: 

var root = location.protocol + '//' + location.host; 
//For a url, let say 'http://google.com/ig', it will return 'http://google.com'

But, Christian Stieber's answer is right If you want to reach any of server's file.

JavaScript is clientside -- it runs on the browser, not the server. A correctly set up server will not let clients access stuff outside the designated area, independent of whether it's from entering an URL into the addressbar, a link contained in an HTML page, or a URL created by JavaScript. It's all the same for the server anyway -- it's just an URL.
