How to get query string parameter from SEO-friendly URL?

Question

I switched from using normal URL parameters to SEO-friendly URLs. For example, I have gone from this...

http://www.example.net/mypage.aspx?id=1

... to this:

http://www.example.net/mypage/1

Using JavaScript or jQuery, what would be the best way to get the id variable of 1?

I currently use a function like this:

// get the values from the query string.
function GetQueryStringParams(sParam) {
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++) {
 var sParameterName = sURLVariables[i].split('=');
 if (sParameterName[0] == sParam) {
 return sParameterName[1];
 }
}

Is there a better way or am I stuck splitting the URL via the /?? And how would you handle multiple parameters?

http://www.example.net/mypage/1/2/3/4/5

Answer 1

The easiest would probably be

var sPageURL = window.location.href.split('/').pop();

• Prescient: That's a very good answer. And it works in this situation. However problems may arise in the future if I use more than 1 variable. Thanks.
• adeneo: Then you'd have to write code that gets those variables based on where in the URL they are. There is no magic function.
