Question

<script>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));}</script>

上面的

script部分在头之间添加！DOCTYPE HTML html头样式。机身下方

<div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"></div>
<div id="drag1" class="drag2" draggable="true" ondragstart="drag(event)" width="336" height="69">Aa</div>

这是实现拖放的正确方法吗？

Answer 1

创建一个from django.db.models import Func class Round2(Func): function = "ROUND" template = "%(function)s(%(expressions)s::numeric, 2)" # Then use it as ,e.g.: # queryset.annotate(ag_roi=Round2("roi")) # qs.aggregate(ag_sold_pct=Round2(Sum("sold_uts") / (1.0 * Sum("total_uts"))) * 100标记并复制span并使用它。请查看代码段。

inner text

#div1 { 
    border: 1px solid blue;
    width: 100px;
    height: 100px;
    display: inline-box;
    overflow-wrap: break-word;
}

#drag1 { 
  border: 1px solid red;
  width: 100px;
  height: 100px;
  display: inline-box;
  overflow-wrap: break-word;
}
