我被這個問題困住了，並沒有找到任何解決方案，因爲大多數人都有他們的ID的問題。jquery sortable serialize返回一個空字符串
我有多個可排序的divs，所有與connectwith連接，它工作正常。
現在我希望每次更改順序（也在不同的級別）以獲得新的排列順序。
這裏是我的代碼：
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"
});
});
這裏是HTML輸出：
<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)">

因此，大家可以看到，排序元素所要的ID node_number。 排序工作正常，但序列化字符串總是空的...
任何幫助非常感謝！
謝謝
