Codigo funcional apenas no perfil

Olá, estou tentando fazer um codigo com jQuery que funcione apenas no perfil, tentei utilizar este codigo:

Código:

var url = document.location.href;
if (url.indexOf("/u") > -1) {}

Ele funcionou no console do firefox, mas quando coloco no forum ele nao funciona

Código:


console.clear();
var url = location.pathname;
if (url.indexOf('/u') == 0) {
  console.log('Estou dentro do perfil!');
} else {
  console.log('Estou fora do perfil!');
}


Código:

var url = location.pathname;
if (url.indexOf('/u') == 0) {
var link = $('#profile_field_13_3').val();
   if (link == '') {
      $('body').css('background', 'url("http://i.imgur.com/iRy6KFn.png") no-repeat scroll center 0px, url("http://i.imgur.com/OIzFUbN.png") repeat-x scroll center 28px, url("http://i.imgur.com/faKwhot.png") repeat scroll center top rgba(0, 0, 0, 0)');
      $('.ipsBox').css('background-color', 'rgba(238, 238, 238, 1)');
      $('#field_id3').css('display', 'none');
   } else {
      $('body').css('background', 'url("http://i.imgur.com/iRy6KFn.png") no-repeat scroll center 0px, url("http://i.imgur.com/OIzFUbN.png") repeat-x scroll center 28px, url("' + link + '") repeat fixed center top rgba(0, 0, 0, 0)');
      $('.ipsBox').css('background-color', 'rgba(238, 238, 238, 0.7)');
      $('.ipsBox_container').css('background-color', 'rgba(255,255,255,0.8) !important');
      $('.ipsVerticalTabbed_tabs li').css('background', 'rgba(246,248,251,0.8');
      $('.ipsVerticalTabbed_tabs li.active a').css({
'background': 'rgba(255, 255, 255, 0.85)',
'border-right': '1px solid rgba(255, 255, 255, 0.85)',
      });
    $('#field_id3 .field_uneditable').on('click', function(){window.open(link, '_blank')});
   }
}


Código:


 jQuery(function () {
    var url = location.pathname;
    if (url.indexOf('/u') == 0) {
        var link = $('#profile_field_13_3').val();
        if (link == '') {
            $('body').css('background', 'url("http://i.imgur.com/iRy6KFn.png") no-repeat scroll center 0px, url("http://i.imgur.com/OIzFUbN.png") repeat-x scroll center 28px, url("http://i.imgur.com/faKwhot.png") repeat scroll center top rgba(0, 0, 0, 0)');
            $('.ipsBox').css('background-color', 'rgba(238, 238, 238, 1)');
            $('#field_id3').css('display', 'none');
        } else {
            $('body').css('background', 'url("http://i.imgur.com/iRy6KFn.png") no-repeat scroll center 0px, url("http://i.imgur.com/OIzFUbN.png") repeat-x scroll center 28px, url("' + link + '") repeat fixed center top rgba(0, 0, 0, 0)');
            $('.ipsBox').css('background-color', 'rgba(238, 238, 238, 0.7)');
            $('.ipsBox_container').css('background-color', 'rgba(255,255,255,0.8) !important');
            $('.ipsVerticalTabbed_tabs li').css('background', 'rgba(246,248,251,0.8');
            $('.ipsVerticalTabbed_tabs li.active a').css({
                'background': 'rgba(255, 255, 255, 0.85)',
                'border-right': '1px solid rgba(255, 255, 255, 0.85)',
            });
            $('#field_id3 .field_uneditable').on('click', function () {
                window.open(link, '_blank')
            });
        }
