我遇到了这个问题并且找不到任何解决办法，因为大多数人的ids都有问题。
我有多个可排序的div，都与connectwith连接，并且工作正常。
现在我希望每次更改顺序（也在不同级别）以获得新的排列序列化。
这是我的代码：
var saveNewOrder = function(){
$( ".level" ).sortable( "refreshPositions" );
var sorted = $( '.level' ).sortable('serialize');
document.getElementById("nodeid_input2").setAttribute("value", sorted);
//document.getElementById("j_idt70:change_order").click();
};
$(document).ready(function(){
levelWidthUpdate();
$('.level').sortable(
{
connectWith: ".level",
update: function(event, ui){
levelWidthUpdate();
saveNewOrder();
},
handle: ".node-heading, .cloud-center, .cloud-left"
});
});
这是html输出：
<div class="level"><span class="node node-default">
<div class="node-heading">first change ever in db</div>
<div class="node-body" id="node_0" onclick="openNode(0)">

如您所见，可排序元素始终具有id node_number。 排序工作正常，但序列化字符串始终为空......
非常感谢任何帮助！
谢谢
答案 0 :(得分：0)
我发现了错误： 首先：带有id的那些不是直接在sortable内的conatiner 第二，如果你有几个可排序的div，由connectwith连接，并且都具有相同的类，它也不起作用......
