I'm using jquery's .each() to iterate over a group of li's. I need a total of all the li's matched. Is the only way to create a count variable outside the .each() and increment this inside the .each()? It doesn't seem very elegant.
var count; $('#accordion li').each(function() { ++count; });

each() jQuery's each() function is used to loop through each element of the target jQuery object — an object that contains one or more DOM elements, and exposes all jQuery functions. It's very useful for multi-element DOM manipulation, as well as iterating over arbitrary arrays and object properties.
You can stop the loop from within the callback function by returning false . $( this ). addClass( "foo" ); });
each(), which is used to iterate, exclusively, over a jQuery object. The $. each() function can be used to iterate over any collection, whether it is an object or an array. In the case of an array, the callback is passed an array index and a corresponding array value each time.
each() function, jQuery's foreach equivalent. jQuery's foreach equivalent can be very useful for many situations. These examples will get you started and teach you how you can loop through arrays, objects and all kinds of HTML elements.
Two options:
$('#accordion li').size(); // the jQuery way $('#accordion li').length; // the Javascript way, which jQuery uses Since jQuery calls length under the hood, it's faster to use that instead of the size() call.
