javascript - removing duplicates from html elements

what's the best way to remove the grapes duplicate from this? there are tons of ways of removing duplicates from simple arrays, but this would be an array with html elements

 <div class="fruit">
      grapes
 </div>
 <div class="fruit">
      bananas
 </div>
 <div class="fruit">
      grapes
  </div>

I've tried using something like

 $('.fruit').each(function () {
      $('.fruit:has("' + $(this).text() + '"):gt(0)').remove();  
 });

Try

var obj = {};
$('.fruit').each(function(){
    var text = $.trim($(this).text());
    if(obj[text]){
        $(this).remove();
    } else {
        obj[text] = true;
    }
})

Demo: Fiddle
