在jQuery / Javascript中上一个“文件夹”或段

Question

If I'm, for example, on this page

www.example.com/admin/bridge/boilerplate

What is the best way (Using plain javascript, or jQuery (Without loading another plugin) to go up one level, eg

www.example.com/admin/bridge

At the moment we are using

window.history.go(-1);

which interferes with submitted forms, etc. This is used normally on a function like this:

$("button.cancel").bind("click", function( e ){
    window.history.go(-1);
    e.preventDefault();
});

Answer 1

Simple:

var url = window.location.href;

if (url.substr(-1) == '/') url = url.substr(0, url.length - 2);

url = url.split('/');
url.pop();

window.location = url.join('/');

Answer 2

var i = window.location.href.lastIndexOf("/");
window.location = window.location.href.substr(0,i)

Answer 3

thanks, but this edited:

$("#back a").click(function() {
    var url = window.location.href;

    if (url.substr(-1) == '/') url = url.substr(0, url.length - 2);

    url = url.split('/');
    url.pop();

    window.location = url.join('/');
});

window.history is actually manipulating what is in your browser history, it is what the back/forward buttons in the browser use.

So, if the only way to get to the directory you are in is to navigate to it by digging down through the parent directories, this would work. However, that is never the only way to get to a page. Users are always able to bookmark the page.
