jQuery.idfy

A simple jQuery-plugin that generates random ids for all elements in the current set that do not yet have one.

Usage

// Generates ids for all elements with class "foo". If they already have an id,
// nothing happens.
$('.foo').idfy();
 
// Like above, but returns the set of ids (i.e., basically an array of strings)
// of each element instead of the element set itself.
$('.foo').ids();
 
// Like above, but returns (and creates if necessary) the id of the first element
// only (or undefined if the set is empty).
$('.foo').id();

Note on ids()

Please note that this function does not really return an array of stings but a jQuery object. If you want a true array, call jQuery's toArray method.
