Regex to get first word after slash in URL

Question

I need to get the first word after slash in a url in javascript, I assume using a regex would be ideal.

Here\'s an idea of what the URLs can possibly look like :

Answer 1

Here is the quick way to get that in javascript

var urlPath = window.location.pathname.split("/");
if (urlPath.length > 1) {
  var first_part = urlPath[1];
  alert(first_part); 
}

Answer 2

Non-regex.

var link = document.location.href.split('/');
alert(link[3]);

Answer 3

Try with:

var url = 'http://mysite.com/section-with-dashes/';
var section = url.match(/^http[s]?:\/\/.*?\/([a-zA-Z-_]+).*$/)[0];

Answer 4

$url = 'http://mysite.com/section/subsection';

$path = parse_url($url, PHP_URL_PATH);

$components = explode('/', $path);

$first_part = $components[0];

Answer 5

Exploding an url in javascript can be done using the official rfc2396 regex:

var url = "http://www.domain.com/path/to/something?query#fragment";
var exp = url.split(/^(([^:\/?#]+):)?(\/\/([^\/?#]*))?([^?#]*)(\?([^#]*))?(#(.*))?/);

This will gives you:

["", "http:", "http", "//www.domain.com", "www.domain.com", "/path/to/something", "?query", "query", "#fragment", "fragment", ""]

Where you can, in your case, easily retrieve you path with:

var firstPortion = exp[5].split("/")[1]

Answer 6

JavaScript with RegEx. This will match anything after the first / until we encounter another /.

window.location.pathname.replace(/^\/([^\/]*).*$/, '$1');
