JavaScript url parsing

Question

I have a url like http://mywebsite.com/folder1/folder2/index

How do I parse this above url and get all the values separately? I want the output to be like:

http, mywebsite.com, folder1, folder2, index 

Answer 1

If your URL is held in a variable, you can use the split() method to do the following:

var url = 'http://mywebsite.com/folder1/folder2/index';
var path = url.split('/');

// path[0]     === 'http:';
// path[2]     === 'mywebsite.com';
// path[3]     === 'folder1';
// path[4]     === 'folder2';
// path[5]     === 'index';

If you want to parse the current URL of the document, you can work on window.location:

var path = window.location.pathname.split('/');

// window.location.protocol  === 'http:'
// window.location.host      === 'mywebsite.com'
// path[1]                   === 'folder1';
// path[2]                   === 'folder2';
// path[3]                   === 'index';

Answer 2

var reader = document.createElement('a');
reader.href = "http://test.example.com:80/pathname/?query=param#hashtag";

Then you can use the following attributes:

reader.protocol
reader.hostname
reader.port
reader.pathname
reader.search
reader.hash
reader.host;
