这里你会看到两组,每组都有3个可放置的容器。您可以将事件从组1移动到组2,并移动到任何插槽。这很好用。
一旦群组已满,我想让用户通过上下移动事件来对该群组进行排序。如果他们选择的话,他们仍然可以将活动移出小组。
你会看到我注释掉的代码,我开始整合可排序的库,但我的行为很奇怪。
注意:我无法单独替换我的draggable / dropable。我需要明确定义的可放置区域(每组3个),以便事件可以存在于组1的第1和第3槽中。
这是我的代码
$(document).ready(function() {
// $(".sort").sortable({
// revert: true
// });
$(".drag").draggable({
//connectToSortable: ".sort",
revert: true
//helper: clone
});
$(".sort").droppable({
drop: function(event, ui) {
if (!($(this).children(".drag").size() == 1)) {
$(this).append(ui.draggable);
ui.draggable.css({
left: 0,
top: 0
});
}
}
});
});
<div>Group 1:
<ul class="parent">
<li class="sort"><a href="" class="drag">event 1</a></li>
<li class="sort"><a href="" class="drag">event 2</a></li>
<li class="sort"></li>
</ul>
</div>
<div>
Group 2
<ul class="parent">
<li class="sort"></li>
<li class="sort"><a href="" class="drag">event 3</a></li>
<li class="sort"><a href="" class="drag">event 4</a></li>
</ul>
</div>
我真的很挣钱,谢谢大家!
