Description
Invokes the handler function for each list element with a single-element list containing only this element. It is very similar to
each(), but instead of giving the element itself it wraps the element in a Minified list. Additionally, you can specify
a sub-selector to iterate over the descendants matches by the selector instead of the list elements.
Example
Create a mouseover toggle for a list:
$('.toggler').per(function(el, i) {
el.onOver(el.toggle('myeffect'));
});
Example
Create click handlers for elements in a list:
$('#list').add(HTML('{{each}}<li>{{this.name}} <a class="del" href="#">Delete</a></li>{{each}}', items)
.per('.del', function(el, index) {
el.on('click', deleteItemByName, [items[index].name]);
}));
