jQuery .each 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.

The best solution is to use the .slice method in jQuery. 

var limit = 5;
$("somelement").slice(0, limit).each(function(i, val) {
    // do stuff
});

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

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

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

var limit = 5;

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

or

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