Read GET URL variables using JavaScript
Support this website by purchasing prints of my photographs! Check them out here.DEPRECATED: This post may no longer be relevant or contain industry best-practices.
Here is a function which will either build an associative array of the GET URL variables on the current page, or return the value of a specified GET variable in JavaScript:
function getUrlVar(requestedKey) {
var vars = [], hash;
var hashes = window.location.href.slice(window.location.href.indexOf('?') + 1).split('&');
for (var i = 0; i < hashes.length; i++) {
hash = hashes[i].split('=');
vars.push(hash[0]);
vars[hash[0]] = hash[1];
}
if (typeof requestedKey == 'undefined') {
return vars;
} else {
return vars[requestedKey];
}
}
Usage:
var site_search = getUrlVar("site_search");
var all_vars = geturlVar();
var site_search_again = all_vars['site_search'];
