Turn array of jQuery elements into jQuery wrapped set of elements

Question

Is there any elegant way of turning [$(div), $(span), $(li)] into $(div, span, li)?

Answer 1

You can use the add method to copy the elements in a jQuery object to another. This will copy all elements from each of the jQuery objects in the array source into the jQuery object items:

// Create an empty jQuery object
var items = $([]);
// Add the elements from each jQuery object to it
$.each(source, function(){ items = items.add(this); });

(Prior to version 1.3.2 the add method doesn't support adding a jQuery object, so you would need to use items.add(this.get()); instead.)
