JavaScript: Parsing the Querystring
Projects » JavaScript » Querystring
Parsing a Querystring in JavaScript
28 May 2008
The Querystring class parses "name=value" pairs from a querystring with client-side JavaScript.
In web browsers you can access the querystring with client-side JavaScript, but there is no standard way to parse out the name/value pairs.
This code provides a "Querystring" object that can parse the current document's querystring, or any querystring passed to the constructor. When passing a string, do not include an initial "?".
This object may be useful for "Ajax" coding, either for getting values for the current page or parsing results sent back in querystring form.
API Reference
- new Querystring([querystring])
-
Creates a new Querystring object, optionally passing a string
qsto parse. Ifqsis omitted, the querystring from the current page is used. - If
querystringis passed, it should not begin with a"?".// Parse the current page's querystring var qs = new Query
