Creating sortable lists using the HTML5 Drag and Drop API.
Article Introduction：The key to implementing the sortable list lies in the HTML5 drag and drop API. The following points should be noted: 1. Set the draggable attribute to make the elements draggable and prevent the default behavior of the dragover to allow placement; 2. Listen to dragstart to record drag data, and update the DOM structure when dropping; 3. Use the dragover event to judge the insertion position in combination with coordinates to realize the sorting logic; 4. Add style optimization experience and handle mobile compatibility issues.

What is the HTML Drag and Drop API?
Article Introduction：The working principle of HTMLDragandDrop API includes the following steps: 1. Set elements to be dragged, set draggable="true" and handle dragstart events to define the behavior at the beginning of the drag; 2. Process events during the dragging process, such as dragover and dragleave to control the drag interaction; 3. Get data in the drop event and perform placement operations, while canceling the default behavior to allow placement; 4. Add visual feedback to improve the user experience. Common use cases include list sorting, file uploading and building kanban interfaces. When using it, you need to pay attention to calling e.preventDefault(), controlling effects and avoiding performance-affecting operations.

How to get the mouse position in JavaScript?
Article Introduction：In web development, there are three main methods for JavaScript to obtain mouse position: 1. Use clientX and clientY to obtain the browser's visual area coordinates, which are suitable for following the cursor or judging areas; 2. Use pageX and pageY to obtain the entire page coordinates including the scrolling part, which is suitable for scenes where absolute positions are required; 3. Use offsetX and offsetY to obtain the relative position of the mouse inside the element, which is often used for canvas or hot zone detection. In addition, after obtaining the mouse coordinates, it can be used to customize the interactive functions such as cursor, drag and drop sorting, drawing tools, hover judgment and game control. Selecting the appropriate coordinate system and debugging multiple values ??can avoid confusion.
