jQuery select first x items of specific class

Share this article

I have written a little jQuery function call .getRange() which returns a specific number of DOM elements
against a jQuery selector (ie elements based on a specified class or id). It uses the jQuery.get() function and is basically an extension of that but allows for a range of elements to be returned. Firstly, you should know to get the first and last elements like so:
var firstSpan = $('span.class:first'),
    lastSpan = $('span.class:last');
To get all the elements that match a specified class like so:
var allSpans = $('span.class').get();
or the nth element like so:
var firstSpan = $('span.class').get(0),
    secondSpan = $('span.class').get(1);
    //etc...
But how to get say the first 10 elements or elements 10-20? It would be nice to go something like:
var mySpans = $('span.class').get(0,10);
Unfortunately, the .get() function doesn’t allow for a range to be passed, but just a single index. So here is my attempt to use the jQuery .get() function to include a range of elements.
(function($)
{
  //function that gets a range of dom elements against a jQuery selector
  //returns an array of dom elements
  $.fn.getRange = function(start,end)
  {
    var elems = [];
    for ( var i = start; i < = end; i++ )
    {
      elems.push(this.get(i));
    }
    return elems;
  };

  //testing
  console.log($('div').getRange(1,10));
  console.log($('div').getRange(10,20));

})(jQuery);
Output: get-range It works this way, but i’m thinking it’s not an optimal solution so does anyone know of a better way to achieve this?
