Не выходит проверка на наличие в json нужного мне значения

Так должно работать :)

 function searchInObj(o, f) { 
      return o.filter(function(o) {
           return Object.keys(o).some(function(k) {
                return o[k] == f ? o[k].includes(f) : null;
           })
      });
  }
   $('#saveVideoBtn').click(function(evt) {
      var cmo = document.getElementById("videoLink").value;
  var keks = JSON.parse('[{"videoLink":""},{"videoLink":""},{"videoLink":""},{"videoLink":"https:\/\/www.ustream.tv\/embed\/9600798"},{"videoLink":"https:\/\/www.rt.com\/on-air\/embed\/"},{"videoLink":"https:\/\/www.ustream.tv\/embed\/13659436"},{"videoLink":"https:\/\/www.ustream.tv\/embed\/9948292"},{"videoLink":"https:\/\/cabinet.glazok.kz\/embed\/v2\/?server=100-pSVOGsxeGuQkxVOnCv6GHk&camera=393216&width=&height=&lang=ru"},{"videoLink":"https:\/\/www.youtube.com\/embed\/5nn_vtDSBWo"},{"videoLink":"http:\/\/www.youtube.com\/embed\/21X5lGlDOfg"},{"videoLink":"https:\/\/www.youtube.com\/watch?v=taD9hqwCb1o"},{"videoLink":""},{"videoLink":""},{"videoLink":"https:\/\/www.youtube.com\/embed\/YAmqhZHb4lw"}]');
