How to use splice

Code:

.content {display: flex; width: 600px; height: 50px; margin: 100px auto;} .list-complete-item {transition: all 1s; display: inline-block; width: 100px; text-align: center; line-height: 50px; font-size: 18px;} .list-complete-enter,.list-complete-leave-to {opacity: 0; transform: translateX (- 30px);} .list-complete-leave-active {position: absolute } {{item.name}} export default {name: "slideanimation", data () {return {list: [{name: "Apple", value: "1.68",}, {name: "Orange", value: "0.9",} {name: "banana", value: "2.58",}, {name: "kiwifruit", value: "3.2",}, {name:" Lingmeng ", value:" 1.2",} {name: "plum", value: "13.2",},],} }, mounted () {/ / timed simulated socket push data, requirements: only 6 nodes are displayed on the page, and several new data are pushed, then delete the header array. SetInterval (() = > {this.animation ();}, 3000);}, methods: {/ / generate integers randomNum (minNum, maxNum) {switch (arguments.length) {case 1: return parseInt (Math.random () * minNum + 1,10) of the specified random range; break Case 2: return parseInt (Math.random () * (maxNum-minNum + 1) + minNum, 10); break; default: return 0; break;}}, animation () {let newItems = [... this.list]; / / A random number, random array let randomCount = 1, addItems = [] RandomCount = this.randomNum (1,3); console.info ("generate Random number-tail add-header deletion", randomCount) Array.from (new Array (randomCount), (n, I) = > I). ForEach (()) = > addItems.push ({name: (Math.random (0,1) * 1000) .tofixed (0), value: Math.random (0,1),})); / / delete several item newItems.splice (0, randomCount) in the head of the array / / add several item newItems.splice (newItems.length, 0,.. addItems) at the end of the array; / / trigger transition-group animation this.list = [... addItems];},},}; dynamic data use wowjs to display animation 1. Install npm install wowjs-- save-dev through npm

Animate.css is installed automatically.

two。 Introducing animate.cssimport 'wowjs/css/libs/animate.css into main.js

Introduce wowjs where the component needs it

There are two ways to use it:

The first kind:

Import {WOW} from 'wowjs' mounted () {new WOW () .init ()}

The second kind:

Import WOW from 'wowjs' mounted () {new WOW.WOW () .init ()}

Configuration parameters in wow instantiation

Add your own configuration parameters selectively

Infinite unlimited playback

If the rendering data of the animated element requests the interface to render, then instantiating wow must be executed in this function using this.$nextTick () after the end of the interface request.
