How to work with the URL in JavaScript

Question

For example I have the URL:
http://www.website.com/example?something=abc&a=b

How can I get the something's content, "abc" and the content of a as strings?

Thanks in advance, Mateiaru

document.URL or window.location You can get current url as string.You can manipulate it.Did you try anything? — Shijin TR, Apr 20 '13 at 11:29

var path = window.location.href;
var index = path.indexOf('?');
var paramstr = path.substring(index + 1);
var paramstrs = paramstr.split('&');
paramstrs.forEach(function(str, index){
    var parts = str.split('=');
    alert('value of ' + parts[0] + ' is ' + parts[1])
});

Use a function helper:

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search)||[,""])[1].replace(/\+/g, '%20'))||null
}

Then call it like:

var aValue = getURLParameter(a);

//var url = window.location.href;
var url = "http://www.website.com/example?something=abc&a=b";
var attributes = url.split("?")[1].split("&");
var keyValue = {};
for(i in attributes)
{
    var pair = attributes[i].split("=");
    keyValue[pair[0]] = pair[1];
}

alert(keyValue["something"]);
alert(keyValue["a"]);
