我正在尝试获取拖放元素的占位符ID。
在第一次拖放时我可以检索它，但是内容来自数据库，并且大多数都是预先填充的。
我现在面临的问题是，我找不到绑定的drop容器的id。
$('document').ready(init);
function init() {
$('[data-type]').bind('dragstart', function (event) {
event.originalEvent.dataTransfer.setData("text/plain", event.target.getAttribute('id'));
});
// bind the dragover event on the board sections
$('#header-container, #header-storage').bind('dragover', function (event) {
event.preventDefault();
//$(event.target).css({"background-color":"#AA0000"});
});
// bind the drop event on the board sections
$('#header-container, #header-storage').bind('drop', function (event) {
event.preventDefault();
var notecard = event.originalEvent.dataTransfer.getData("text/plain");
event.target.appendChild(document.getElementById(notecard));
var room = document.getElementById(event.target.id).parentNode;
console.log(room);
// Turn off the default behaviour
// without this, FF will try and go to a URL with your id's name
var $id = $(event.target).attr("data-element-id");
alert('you dropped ' + notecard + ' into '+$id+' but into what container i do not know? In header-container or storage container?');
});

var $id = $(event.target).attr("data-element-id");之后添加：
alert( $(event.target).closest('#header-container, #header-storage').attr('id'));
