HMCTS Frontend contains the code you need to start building a user interface for HMCTS.

HMCTSFrontend.removeAttributeValue = function(el, attr, value) {
  var re, m;
  if (el.getAttribute(attr)) {
    if (el.getAttribute(attr) == value) {
      el.removeAttribute(attr);
    } else {
      re = new RegExp('(^|\\s)' + value + '(\\s|$)');
      m = el.getAttribute(attr).match(re);
      if (m && m.length == 3) {
        el.setAttribute(attr, el.getAttribute(attr).replace(re, (m[1] && m[2])?' ':''))
      }
    }
  }
}

HMCTSFrontend.addAttributeValue = function(el, attr, value) {
  var re;
  if (!el.getAttribute(attr)) {
    el.setAttribute(attr, value);
  }
  else {
    re = new RegExp('(^|\\s)' + value + '(\\s|$)');
    if (!re.test(el.getAttribute(attr))) {
      el.setAttribute(attr, el.getAttribute(attr) + ' ' + value);
    }
  }
};
