我正在尝试从图像上的列表复制div，以便将div合并到图像中。拖放工作良好，除非将div拖动到可放置的div之后将无法再次拖动。在示例中，我需要能够多次将“患者名称”拖动到可放置对象。任何帮助是极大的赞赏！这是代码：
<!DOCTYPE html>
<html>
<head>
<style>
.draggable {
width: 250px;
height: 20px;
background: #fff;
padding: 10px;
border: 1px solid black;
margin: 5px;
}
.draggable:hover {
cursor: pointer;
}
.droppable {
border: 1px solid black;
width: 600px;
height: 800px;
background: lightgrey;
margin: 5px;
}
.table {
display: table;
}
.tableRow {
display: table-row;
}
.tableCol {
display: table-cell;
vertical-align: top;
}
.leftCol {
}
.rightCol {
}
</style>
</head>
<body>

</div>
<div class="tableCol rightCol">
<div class="draggable">Patient Name</div>
<div class="draggable">Owner Name</div>
<div class="draggable">Owner Address</div>
</div>
</div>
</div>
<script type="text/javascript">
$('.draggable').draggable({
revert: "invalid",
stack: ".draggable",
helper: function (e, ui) {
return $(this).clone();
},
stop: function (e, ui) {
$('.draggable').draggable().data()["ui-draggable"].cancelHelperRemoval = true;
},
});
$('.droppable').droppable({
accept: ".draggable",
drop: function (event, ui) {
var droppable = $(this);
var draggable = ui.draggable;
var newClone = $(ui.helper).clone();
newClone.draggable();
$(this).append(newClone);
},
});
</script>
</body>
</html>
在运行代码时始终检查调试器。
