2. var abcdef = ["A", "B", "C", "D", "E", "F"];
3.     var time = 500;
4. 
   
5.     jQuery.each(abc, function(i, item) {
6.         setTimeout( function(){ $("#container").empty().append(item); }, time)
7.         time += 10000;
8.     });
10.          <div id="container"></div>
11.         <input type="button" value="Start" />
12.         <input type="button" value="Stop" />

So all the letters is shown one by one but only but only one round. I need the each loop to continue until I press button "Stop". Then when pressing "Start", then I would want the each function to continue again.
