为什么ngDraggable只能在角度ng-repeat中工作一半

Question

对于我的生活，我无法弄清楚为什么我的图像有时只能拖放。看起来当我无法放下时，在开始拖动之前单击图像一次（有时）。我原以为这是一个焦点问题，所以我尝试使用jQuery专注于调用drop-success函数中的ng-drag div。 我也一直在改变css，我感觉可能与它有关，但是我再次不确定它是否有某种类型的广播问题。 我根本没有碰到ngDraggable.js文件...... 移动似乎很好，但在桌面上这是非常奇怪的，似乎是间歇性的。请帮忙。链接到我的github回购： https://github.com/TransientCW/BabyBox-Angular

不幸的是，它工作正常。我在触摸屏笔记本电脑上，并得到了奇怪的行为。在普通的笔记本电脑上，拖动功能运行良好，在桌面上，它也很好用.....
