当我将容器缩放到 0.5 时，DND 无法正常运行。 请任何人帮我解决这个问题。
HTML:
<div id="container">
<div id="dragContainer">
<div class="draggable">drag1</div>
<div class="draggable">drag2</div>
</div>
<div id="dropContainer">
<div class="droppable">drop1</div>
<div class="droppable">drop2</div>
</div>
</div>
JS:
$(".draggable").draggable({
revert: 'invalid'
})
$(".droppable").droppable()
我已经创建了该问题的 fiddle 链接:https://jsfiddle.net/7eqnhsp3/
最佳答案
我创建了在任何缩放情况下都可以运行的演示
