我将元素拖放到目标div,也不将其从源div中删除
使用下面的代码拖放工作正常,但我试图保留源div中的元素而不删除它
HTML:
<html>
<head>
</head>
<body>
<p>Drag the elements image into the rectangle:</p>
<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)">
<div id="drag1" draggable="true" ondragstart="drag(event)" width="336" height="69">Input</div>
<div id="drag2" draggable="true" ondragstart="drag(event)" width="336" height="69">Radio</div>
<div id="drag3" draggable="true" ondragstart="drag(event)" width="336" height="69">Checkbox</div>
<div id="drag4" draggable="true" ondragstart="drag(event)" width="336" height="69">Dropdown</div>
</div>
<br>
<div id="div2" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<br>
</body>
</html>
JS:
function allowDrop(ev) {
ev.preventDefault();
}
function drag(ev) {
ev.dataTransfer.setData("text", ev.target.id);
}
function drop(ev) {
ev.preventDefault();
var data = ev.dataTransfer.getData("text");
ev.target.appendChild(document.getElementById(data));
}
CSS:
#div1, #div2 {
width: 350px;
height: 100px;
padding: 10px;
border: 1px solid #aaaaaa;
}
#drag1,#drag2,#drag3,#drag4{
border:1px solid black;
margin:5px;
}
