我有可拖動的元素（draggable =「true」），以改變它們的順序，我想添加到這些元素與jQuery的「點擊」事件，我已經嘗試過但我無法得到它。是否可以將點擊或雙擊事件添加到本機HTML5可拖動元素？有人可以幫助我。本機HTML5拖放和點擊事件
var dragSrcEl = null;
function handleDragStart(e) {
// Target (this) element is the source node.
dragSrcEl = this;
e.dataTransfer.effectAllowed = 'move';
e.dataTransfer.setData('text/html', this.outerHTML);
this.classList.add('dragElem');
}
function handleDragOver(e) {
if (e.preventDefault) {
e.preventDefault(); // Necessary. Allows us to drop.
}
this.classList.add('over');
e.dataTransfer.dropEffect = 'move'; // See the section on the DataTransfer object.
return false;
}
function handleDragEnter(e) {
// this/e.target is the current hover target.
}
function handleDragLeave(e) {
this.classList.remove('over'); // this/e.target is previous target element.
}
function handleDrop(e) {
// this/e.target is current target element.
if (e.stopPropagation) {
e.stopPropagation(); // Stops some browsers from redirecting.
}
// Don't do anything if dropping the same column we're dragging.
if (dragSrcEl != this) {
// Set the source column's HTML to the HTML of the column we dropped on.
//alert(this.outerHTML);
//dragSrcEl.innerHTML = this.innerHTML;
//this.innerHTML = e.dataTransfer.getData('text/html');
this.parentNode.removeChild(dragSrcEl);
