Let's say I have a list that looks like this:
<ul>
<li id="q"></li>
<li id="w"></li>
<li id="e"></li>
<li id="r"></li>
<li id="t"></li>
<li id="y"></li>
<li id="u"></li>
<li id="i"></li>
<li id="o"></li>
</ul>
I need to do something like this:
function get_important_elements() {
// completely contrived;
// elements are guaranteed to be contained within same ul
// but nothing else unique in common (class, attrs, etc)
return $('#q, #w, #r, #u, #i, #o');
}
function group_adjacent($elems) {
return $elems; //:(
}
$(function () {
var $filtered_list = get_important_elements();
var groups = group_adjacent($filtered_list);
// groups should be
// (shown by ID here, should contained actual elements contained
// within jQuery objects):
// [$([q, w]), $([r]), $([u, i, o])]
});
How could I go about this?
Note that the IDs and classes used in the list are 100% contrived. In the real code upon which I'm basing this, I have a collection of li elements that are a subset of the lis contained in a single ul. This subset was determined by their contents, which are not important to the question at hand, not by class. They only share a class in the example for ease of getting my point across.
function group_adjacent($elems) {
var rArr = [],
currArr = $([]);
$elems.each(function() {
var $this = $(this);
currArr = currArr.add($this);
if (!$elems.filter($this.next()).length) {
rArr.push(currArr);
currArr = $([]);
}
});
return rArr;
}
