私はあなたがこのようなものが好きだと思います:
HTML:
<div id="container">
<ul>
<li>
<span class="title">Title of the article</span>
<span class="date" data-value="2012/05/01">2012/05/01</span>
</li>
</ul>
<ul>
<li>
<span class="title">Title of the article</span>
<span class="date" data-value="2012/05/05">2012/05/05</span>
</li>
</ul>
<ul>
<li>
<span class="title">Title of the article</span>
<span class="date" data-value="2012/04/10">2012/04/10</span>
</li>
</ul>
</div>
jQuery:
var mainlists = $('#container ul'),
min = 550;
function merge_lists() {
if (!$('#container').hasClass('merged')) {
var temp = mainlists.clone(true),
lists = $('li', temp);
lists.sort(function(a, b) {
var d1 = $('span.date', a).data('value'),
d2 = $('span.date', b).data('value');
if (new Date(d1).getTime() > new Date(d2).getTime()) return 1;
});
$('#container').empty().append($('<ul>', {
html: lists
}));
$('#container').addClass('merged');
}
}
function restore_lists() {
if ($('#container').hasClass('merged')) {
$('#container').empty().append(mainlists.clone(true));
$('#container').removeClass('merged');
}
}
$(window).resize(function() {
var winWidth = $(window).width(),
winHeight = $(window).height();
$('#resolution').html(winWidth + 'px x ' + winHeight + 'px');
if (winWidth < min) {
merge_lists();
$('body').css('background', '#ddd');
} else {
restore_lists();
$('body').css('background', '#fff');
}
});
