Hope that helps If you don't have too many objects in your database and you want to run a quick one-off script in the console you can do this:
desired_product_ids = [801, 808]
User.find_each do |user|
  unless (user.product_ids & desired_product_ids).empty?
    give_gift user

def give_gift(user)
  # your gift logic
User.where(<your condition here>).find_each do |user|
  give_gift user

Hope this helps You can achieve this using jQuery with the jQuery.next function - http://api.jquery.com/next/.
For a set of html like this:
<nav><a class="showNext">Show Next</a></nav>
<div class="content" style="display:none">I'm hidden</div>
<div class="content">I'm Visible</div>
$('.showNext').bind('click', function(e) {
    window.location.hash = $(this).next('.content:visible').attr('id') + 'marker';

fixed the issue. Will look into that further Like @Marc B and @Terry say, you have just to do an intersection.
Here's a version without Jquery :
function intersection(a, b)
  var result = [], ai = 0, bi = 0;
  while( a.length > ai && b.length > bi )
     if(a[ai] < b[bi] ){
     else if(a[ai] > b[bi] ){ 
  return result;

var arr1 = [

var arr2 = ['Supervisor','monitor'];

var arr3 = [];

  if(intersection(value.role, arr2).length === arr2.length){

wish help you to fix your issue You could find the string by using Array#includes.
var blocklist = ['jack', 'mark', 'jhon', 'fox'],
