Custom Events

Same as jQuery, but...

//When filter by professor/e-resources is selected
$('#filters').delegate('a', 'click',function(){
var filter = $(this).attr('id');
$('#listInfo').html('Refreshing list...');
if (filter.indexOf("Prof") !== -1 ) {
ajax_filter_professor(courseNum);
$('#showItems').removeClass('books courses
booksProf eitems').addClass('profs');
}


Custom Events

Same as jQuery, but... Click
TAP
TAPHOLD
SWIPE
VCLICK
(one event to rule them all)

“Multiple click events causing navigation and form element issue –
In certain situations, when tapping an element, tap/click events
seem to fire twice on links and is due to edge
cases where the target of the touch event and mouse event don’t
match due to how the browsers calculate tolerances for these
events. This is most pronounced on Android 2.1”

$('[data-role=page]').live('pageshow',
