jQuery .each question

Question

Is it possible to run a jQuery .each statement a certain amount of times rather then for each of the items being iterated? The JSON being iterated is a last.fm feed, and of course, they ignore the "limit" request often. I would like to bypass this error by only running the .each statement so many times.

Answer 1

Return false out of the iterator when you want to stop. The first parameter to your iterator is the index (when looping through arrays).

Answer 2

var limit = 5;

$("somelement").each(function(i, val) {
      if(i > limit) return false;
      // do stuff
});

or

$("somelement:lt(5)").each(function() {
      // do stuff
});

Answer 3

Rather than modify the .each, modify your selector to select only the first 'n' elements.

Answer 4

Define a variable before your loop, increment it within the each, and if(myvar == 10){return false;}

Returning 'false' from within the each function completely stops the loop http://docs.jquery.com/Core/each
