Article Introduction：TheDragandDrop API is a browser built-in feature for drag-and-drop interaction. It supports multiple use cases: 1. Reorder to-do lists; 2. Build UI components that can place elements; 3. Implement drag-and-drop file uploads. When using it, you need to set draggable="true" and listen for dragstart event to enable drag, and set dropzone and handle dragover and drop events to receive drag and drop content. Note: Not all elements can be dragged by default, the data types need to be unified, and there may be restrictions on cross-domain and mobile terminals.

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

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：In the drag-and-drop operation, the dataTransfer object realizes data transfer through setData() and getData(). 1. Use setData() to set data in the dragstart event. You need to specify the MIME type and content, such as 'text/plain' and 'text/uri-list'; 2. Use getData() to extract data according to the same type in the drop event, and you can also use the type attribute to determine the available types; 3. You can control the drag effect prompts through effectAllowed and dropEffect, such as copying or moving; 4. When dragging multiple items, you can use JSON format to encapsulate and drag text
