<p>该实例演示了如何使用 HTML DOM 向 文档对象添加 "ondragstart", "ondrag", "ondragover" 和 "ondrop" 事件。 </p>
<p>在两个矩形框中来回拖动 p 元素:</p>
<div class="droptarget">
    <p draggable="true" id="dragtarget">拖动我!</p>
</div>
<div class="droptarget"></div>
<p style="clear:both;"><strong>注意：</strong>Internet Explorer 8 及更早 IE 版本或 Safari 5.1 及更早版本的浏览器不支持 drag 事件。</p>
<p id="demo"></p>
<script>
/* 拖动时触发 */
document.addEventListener("dragstart", function(event) {
    event.dataTransfer.setData("Text", event.target.id);
    document.getElementById("demo").innerHTML = "开始拖动 p 元素";
});
/* 拖动完成时触发*/
document.addEventListener("dragover", function(event) {
    event.preventDefault();
});
document.addEventListener("drop", function(event) {
