Access GET directly from JavaScript?

Question

I suppose I could use PHP to access $_GET variables from JavaScript:

<script>
var to = $_GET['to'];
var from = $_GET['from'];
</script>
<script src="realScript" type="text/javascript"></script>

But perhaps it's even simpler. Is there a way to do it directly from JS?

Answer 1

Look at

window.location.search

It will contain a string like this: ?foo=1&bar=2

To get from that into an object, some splitting is all you need to do:

var parts = window.location.search.substr(1).split("&");
var $_GET = {};
for (var i = 0; i < parts.length; i++) {
    var temp = parts[i].split("=");
    $_GET[decodeURIComponent(temp[0])] = decodeURIComponent(temp[1]);
}

alert($_GET['foo']); // 1
alert($_GET.bar);    // 2
