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 .

A slight variation of @alex 's answer for those who want to be able to match non-predetermined parameter names in the url.

var getUrlValue = function(name, url) {
  var valuesRegex = new RegExp('(?:^|[&;])' + name + '=([^&;]+)', 'g'),
      matches,
      values = [];

  while (matches = valuesRegex.exec(url)) {
      values.push(decodeURIComponent(matches[1]));   
  }

  return values;
}

var url = 'http://www.somedomain.com?id=12&names=bill&names=bob&names=sally';

// ["bill", "bob", "sally"]
var results = getUrlValue('names', url);

jsFiddle
