var $selected = $();
var $itemLv1 = $("#create-summary .lv1");
$itemLv1.click(function(){
$selected = $(this);
$(this).toggleClass('clicked').siblings().removeClass('clicked');
});
$("#moveUp").click(function(){
$selected.add($selected.nextUntil(":not(.lv2)"))
.insertBefore($selected.prevAll(".lv1:first"));
});
$("#moveDown").click(function(){
$selected.add($selected.nextUntil(":not(.lv2"))
.insertAfter($selected.nextAll(".lv1:first"));
});

.lv2, .lv3 {
margin-left:15px;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="create-summary">
<div class="lv1"> Introduction</div>
<div class="lv1">1. AAA</div>
<div class="lv1">2. BBB</div>
<div class="lv1">3. CCC
<div class="lv2">3.1 aaa</div>
<div class="lv2">3.2 bbb</div>
<div class="lv2">3.3 ccc</div>
<div class="lv2">3.4 ddd
<div class="lv3">3.4.1 xxxxx</div>
<div class="lv3">3.4.2 yyyyy</div>
<div class="lv3">3.4.3 zzzzz</div>
</div>
</div>
<div class="lv1">4. DDD</div>
<div class="lv1">5. EEE</div>
</div>
<button type="button" id="moveUp">Up </button> /
<button type="button" id="moveDown">Down</button>
现在,我可以使用其子元素向上或向下移动lv1元素。
但是,如何只在子div中移动div元素?(仅限lv3或lv4甚至lv5或lv6)
Fir示例,我想仅在lv2中移动“ccc”或仅在lv3中移动xxxxx。 有什么方法可以做到吗?

我认为您需要这样的功能,
var $selected = $();
var $itemLv1 = $("#create-summary [class^=lv]");
$itemLv1.click(function (e) {
$selected = $(this);
var x = $(this).toggleClass('clicked');
$("[class^=lv]").not(x).removeClass("clicked child").addClass("child");
x.siblings().removeClass('clicked');
e.stopPropagation();
});
$("#moveUp").click(function () {
$selected.insertBefore($selected.prev("[class^=lv]"));
});
$("#moveDown").click(function () {
$selected.insertAfter($selected.next("[class^=lv]"));
});
