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.

How to handle mouse events on a canvas?
Article Introduction：To handle mouse events on canvas, you need to manually monitor and judge the trigger area in combination with coordinates. 1. When obtaining the mouse position, you need to convert clientX and clientY to the internal coordinates of canvas. The formula is x=e.clientX-rect.left, y=e.clientY-rect.top; 2. If there is a zoom or transform style, the coordinates need to be adjusted accordingly; 3. To determine whether to click on the graphic, you need to record the graphics information in advance and detect whether the coordinates fall in the corresponding area when clicking; 4. To achieve the hover effect, you can listen to mousemove and clear and repaint canvas or use double buffering technology; 5. Note that the mobile terminal needs to use touch events to replace hove

Debouncing and Throttling Functions for Performance Optimization in JavaScript
Article Introduction：Debounce and throttle are two technologies that optimize the execution frequency of high-frequency events in JavaScript. 1. The core of Debounce is that it only executes the last time after multiple triggers, which is suitable for scenes where input box search, window adjustment, etc. that need to wait for stop operation; 2. The core of Throttle is that it only executes once within a fixed time interval, which is suitable for scenes where scroll monitoring, mouse movement and other scenarios that need to limit the frequency of execution. The difference between the two lies in the triggering timing and applicable situation: the debounce is executed after the trigger is stopped, and the throttle is executed periodically. When using it, you need to pay attention to the functions of context binding, parameter passing and optional immediate execution, and can be implemented with the help of the Lodash library.
