Expressjs Add Class To Li Element In Partial

I have this menu in a partial:

• Profile

• $(function() {
    // put the possible page titles here
    // they must be in the url also
    var possible_pages = ['profile', 'test'], 
        path = window.location.pathname,
        pattern, page, i, len;
  
    for (i = 0, len = possible_pages.length; i <= len; i++) {
      page = possible_pages[i];
      pattern = new RegExp(page);
      if (pattern.test(path)) {
        $('.submenu .' + page).addClass('selected');
        break;
      }
    }
  });
