jQuery 拖放模拟不适用于最后一个可拖动对象
jQuery drag and drop simulation does not work for the last draggable
我正在尝试使用 jquery-simulate-ext plugin of jquery-ui 来模拟拖放模拟。
在我给出场景的细节之前，让我给你看一下 js fiddle here .
我有 3 列 divs。在第一列中，我有 3 个带有国家名称的可拖动对象，在第二列中有 3 个空白 divs 的可拖动对象，在第三列中有 3 个带有城市名称的普通 divs。因此，在第 1 列的所有可拖动对象都被放到第 2 列后，第 2 列和第 3 列的行将具有国家-城市关系的意义。
但问题是模拟完成后，第一个和第二个可拖动对象被放置在预期的可放置对象上，但第三个可拖动对象只是粘在鼠标上而不是放置在可放置对象上。要找到行为，在加载上述 js fiddle 页面后，只需将鼠标光标移动到结果部分，您将看到一个可拖动对象也随着鼠标移动。您必须单击某处才能使可拖动对象位于可放置或可拖动部分（取决于您单击的区域）。这种情况 仅在 Firefox 中发生，而 在 chrome 中，可拖动对象仅在适当的可放置部分内随光标一起移动，然后位于里面自动。
我想要的是：和其他draggables一样，第三个draggable不应该随着鼠标的移动而移动，应该自动坐在所需的 droppable 上。
代码解释：
每个具有 class draggable_div 的可拖动 div 都有一个属性 data-index（值 1、2、3 等）。同样的情况也适用于可放置的 divs （class droppable_blank）。现在在 JS 代码的开头，我有一行：
answers_found='[1,2,3]';
这些基本上是来自可拖动对象的 data-index 值。值的顺序仅显示 data-index 可拖动对象位于可放置对象上时的值的顺序。在上述情况下，第一个值为 1，因此它将是第一个（不是第二个或第三个）可拖动对象，它位于第一个可放置对象上。同样，第二个和第三个可拖动对象将连续位于第二个和第三个可拖动对象上。
代码执行下面的for循环
for(var i =0; i<answers_found.length; i++){
从 answers_found 数组中获取每个值。该值是可拖动的 data-index 属性值。然后 call_trigger_drop 函数被赋予 2 个参数：
call_trigger_drop(parseInt(answer_found_indiv),droppable_index);
第一个是可拖动索引，第二个是 对应的 可放置索引，即可拖动将位于可放置上。实际模拟发生在以下行中：
draggable.simulate("drag", {
dx: dx,
dy: dy
});
TL;DR:
模拟第 1 列的可拖动对象落在第 2 列的可拖动对象上，而第 3 列只是正常的 divs。在拖放模拟之后，第 3 个可拖动对象不会位于 Firefox 中的第 3 个可拖动对象上，而是随着光标移动，直到发生点击。 如何让它像其他可拖动对象一样自动放置在可拖动对象上？

因为它只模拟drag事件，没有drop，所以用drag-n-drop代替。
