如何在不实际拖放的情况下使用 jQuery UI Droppable 触发 Drop 事件? [英] How do I trigger the Drop event with jQuery UI Droppable without actually dragging and dropping?

问题描述

我有一个带有放置事件处理程序的 droppable:

I have a droppable with a drop event handler:

$(this).droppable({
  drop:function(){
    console.log('OMG You Dropped It!');
  }
});

我有一个可拖动:

$(this).draggable();

我想要做的是在 droppable 上触发放置事件处理程序，而无需实际拖放 draggable.我想在不实际执行行为的情况下模拟实际行为.

What I want to do is trigger the drop event handler on the droppable without actually dragging and dropping the draggable. I want to simulate the actual behavior without physically performing the behavior.

我认为这样的事情会做:

I thought something like this would do:

$(droppable).trigger('drop', [draggable]);

不幸的是，事情并没有那么简单.有谁知道我如何才能做到这一点?

Unfortunately, it's not quite that simple. Does anyone know how I can accomplish this?

推荐答案

您应该将 drop 处理程序中的代码移动到单独的函数中.
然后，您可以在处理程序和其他地方调用该函数.

You should move the code in your drop handler to a separate function.
You can then call the function both in the handler and elsewhere.
