虽然该方式大幅度的提高了之前dragula带来的性能问题。但是经过测试 还是会在初始化的时候bind event。即在鼠标未点击的时候 事件就绑定了。带来了额外的性能开销。所以此种方案也不是最佳方案 虽然当时觉得性能还行。但是始终不是完全之策,万幸的是material2 cdk 出来了一款高性能组件 drag and drop 。 阅读源码之后...
The Angular Drag and Drop library allows you to choose to show a Drag Hint instead of the entire element when dragging. When the user grabs and drags an element, they will see the image or element that you designate as the Drag Hint rather than the entire element. This is essentially a ...
