How do I handle drag events (e.g., dragstart, dragover, drop)?
Article Introduction：The key to handling drag and drop events is to understand the event flow and correctly set the data delivery and target area response. 1. Drag and drop events include dragstart, drag, dragenter, dragover, drop and dragend. They each trigger and undertake different tasks at different stages. For dragstart, data is set, dragover control allows placement, and drop completes data reception; 2. To make elements draggable, draggable="true" must be set and use e.dataTransfer.setData() to pass data in dragstart; 3. The common reason why drop does not trigger is that it is not in draggo.
