Is it possible using jquery (or just javascript) to check for the existence of a query string on the URL?

@Mic - if the question is to be taken literally (just "is it present?"), it's a different question with a much simpler answer.Matchu– Matchu2010-07-12 21:03:28 +00:00Commented Jul 12, 2010 at 21:03

document.location contains information about the URL, and document.location.search contains the query string, e.g. ?foo=bar&spam=eggs. As for testing its presence, how about:
if(document.location.search.length) {
// query string exists
} else {
// no query string exists
}
No jQuery required :o

I would think you could use the javascript match operator.
var url = window.location.search;
if (url.match("your string").length > 0) {
}

fyi, this is poor because match can return nulls, and putting length of a null object would result in an error

True. That problem can be solved via something like:
if(url.indexOf("your string") !== -1)Check out http://rixi.us/post/791257125/get-and-server-free-dynamic-contet
a method to extract any query string parameters
Use::
if (_GET['key']) {
var key = _GET['key']
}

-1. OP specified jQuery (or Javascript) not PHP as the language they are using.

@theringostarrs It actually is not PHP, it is just a small amount of javascript that I wrote a long while back that allows you to extract GET variables from the URL. Vastly outdated, and I'm not sure that link works anymore, but it is/was Javascript.

Why did you mix JavaScript and PHP in literally the same if-block on a JavaScript question
