Question

我正在尝试创建一个拖放操作，以允许将可拖动对象放置在两个可放置目标之间。两个可放置目标都必须同时接收和接受可拖动对象，并更新其“已拖放！”状态。

我已经使它工作了，但它有一些问题。您必须在两个放置目标之间移动对象并将其重新放置几次，然后它们才能显示放置状态。

这是我想要的结果：

您可以更改可触摸物体的容忍度

http://api.jqueryui.com/droppable/#option-tolerance

$( "#droppablea" ).droppable({
  tolerance: "touch",
  drop: function( event, ui ) {
    $( this )
      .addClass( "ui-state-highlight" )
      .find( "p" )
        .html( "Dropped!" );
  }
});
$( "#droppable" ).droppable({
  tolerance: "touch",
  drop: function( event, ui ) {
    $( this )
      .addClass( "ui-state-highlight" )
      .find( "p" )
        .html( "Dropped!" );
  }
});
