Article Introduction：HTML5 natively supports drag and drop function, and interacts by setting draggable attributes and listening to dragstart, dragover, and drop events. 1. Set the element draggable="true" to enable drag; 2. Use dataTransfer.setData() to pass data in dragstart; 3. The target area listens to the dragover and blocks the default behavior to allow placement; 4. Get data and process content in the drop event; precautions include cross-domain restrictions, visual feedback, mobile compatibility and file upload support. Mastering these key points can achieve basic drag-and-drop interaction.

Article Introduction：The key steps to implement the draggable function include: 1. Use the draggable attribute of HTML5 to make the elements draggable; 2. Set drag data through the dragstart event; 3. Listen to the dragover and drop event processing placement logic in the target area; 4. Use the FileList object to implement drag and drop upload. The HTML5 native drag and drop API uses a series of event control processes, such as dragstart, dragover, drop, etc., where draggable custom elements need to be set to set draggable="true" and bind dragstart event, and call setData() to save data. The dr must be blocked when handling drag and drop
