Using anti-shake technology in Vue can effectively reduce the number of client requests and improve page performance and user experience. Anti-shake technology means that after the same event is triggered multiple times within a period of time, only the last triggered event will be executed, while previously unexecuted events will be ignored.
The anti-shake technology in Vue can be implemented through JS functions. Let us take a look at how to implement anti-shake technology in Vue.
- Introducing the anti-shake function in the Vue instance
The anti-shake function can be used in the Vue instance to delay triggering events. The way to introduce the anti-shake function in the Vue instance is as follows:
import debounce from 'lodash/debounce'; export default { // ... methods: { handler: debounce(function () { // 处理事件 }, 500) } }
In the method of using anti-shake technology, we need to pass in the function that needs to be delayed and the time that needs to be delayed. The 500 here means a delay of 500 Trigger event in milliseconds.
- Using the anti-shake function in the template
The method of using the anti-shake function in the template is similar to introducing the anti-shake function in the Vue instance. You only need to add the anti-shake function Just define it in the template.
<template> <div> <input> </div> </template> <script> import debounce from 'lodash/debounce'; export default { data() { return { search: '' } }, methods: { handler: debounce(function () { console.log('处理事件') }, 500) } } </script>
In the template, we need to add an anti-shake function to the event that requires anti-shake technology. @keyup here means adding an anti-shake function to the keyup event.
- Customized anti-shake function
You can also customize the anti-shake function through Vue's mixin.
import debounce from 'lodash/debounce'; export default { created() { this.$debounce = function (fn, wait) { return debounce(fn, wait); }; } }
Here, we define a function called $debounce through the mixin of the Vue instance. The usage is similar to the method of introducing the anti-shake function before. When using it, we can directly call the $debounce function.
<template> <div> <input> </div> </template> <script> export default { data() { return { search: '' } }, methods: { handler() { console.log('处理事件') } } } </script>
In the template, we can directly call the $debounce function, which will automatically perform anti-shake operations.
Summary:
The use of anti-shake technology in Vue is very simple. You only need to introduce the anti-shake function, and then add the anti-shake function to the events that need to be used. Using anti-shake technology can effectively reduce the number of client requests and improve page performance and user experience.

Using indexes as keys is acceptable in React, but only if the order of list items is unchanged and not dynamically added or deleted; otherwise, a stable and unique identifier should be used as the keys. 1) It is OK to use index as key in a static list (download menu option). 2) If list items can be reordered, added or deleted, using indexes will lead to state loss and unexpected behavior. 3) Always use the unique ID of the data or the generated identifier (such as UUID) as the key to ensure that React correctly updates the DOM and maintains component status.

The article discusses HTML5 audio formats and cross-browser compatibility. It covers MP3, WAV, OGG, AAC, and WebM, and suggests using multiple sources and fallbacks for broader accessibility.

SVG and Canvas are HTML5 elements for web graphics. SVG, being vector-based, excels in scalability and interactivity, while Canvas, pixel-based, is better for performance-intensive applications like games.

HTML5 enables drag and drop with specific events and attributes, allowing customization but facing browser compatibility issues on older versions and mobile devices.
