    copied!<p>I don't know if this is the right approach, but I want to do exactly what the title says. I'm missing some jQuery concepts, as I'm new to it.</p> <p>I am using jQuery.rest: <a href="https://github.com/lyconic/jquery.rest" rel="nofollow">https://github.com/lyconic/jquery.rest</a></p> <p>This script periodically checks to see if the online and offline users have been updated:</p> <pre><code>&lt;!-- Online checker --&gt; &lt;script type="text/javascript"&gt; $(function(){ setInterval (checkTrackings, 5000); var js = '&lt;checkTrackings&gt; '; function checkTrackings(){ $.read( '/users/{id}/check', { id: &lt;%= @user.id.to_json %&gt; }, function (response) { $("ul#online").empty(); $("ul#offline").empty(); // Code to add users back to list $("ul#online").html('&lt;%= escape_javascript(render(@online_users)).html_safe %&gt;') $("ul#offline").html('&lt;%= escape_javascript(render(@offline_users)).html_safe %&gt;') console.log(js + 'Check trackings'); } ); } }); &lt;/script&gt; </code></pre> <p>However, instead of @online_users and @offline_users, I need the returned JSON objects and need to convert them to said variables. The method that this script calls is here:</p> <pre><code> # Updates contacts def check @online_users = Array.new @offline_users = Array.new @user = User.find(params[:id]) @followed_users = @user.followed_users @followed_users.each do |followed_user| @online_users.push(followed_user) if followed_user.state.online end @offline_users = @followed_users - @online_users respond_to do |format| format.js { render :json =&gt; { :online_users =&gt; @online_users, :offline_users =&gt; @offline_users } } end end </code></pre> <p>Any other tips would be nice, too. I'm very new to web dev. Thanks for the help!</p>
