I'm trying to use javascript to do a regular expression on a url (window.location.href) that has query string parameters and cannot figure out how to do it. In my case, there is a query string parameter can repeat itself; for example quality, so here I'm trying to match quality= to get an array with the 4 values (tall, dark, green eyes, handsome):

You can use a regex to do this.

var qualityRegex = /(?:^|[&;])quality=([^&;]+)/g,

    matches,

    qualities = [];



while (matches = qualityRegex.exec(window.location.search)) {

    qualities.push(decodeURIComponent(matches[1]));   

}

jsFiddle.

The qualities will be in qualities.
