css3 实现数字滚动的动画组件 （react版）

 

 

 

在写前端页面的时候，经常会遇到需要写数字滚动动画的需求，那我们今天就来实现一个。先去官网看下demo的效果吧：官网

懒得写html版了，有需要的就给我留言吧，就直接贴一个react组件版，直接拿去用。

react 组件JSX:

import React, { Component } from "react" import "./index.scss" export default class NumbersCount extends Component { constructor(props) { super(props) this.state = { visible: true } } render() { const { showValue } = this.props const numberList = (showValue + "").split("") return <div className="numbers-container" style={this.props.numberContainerStyle}> { numberList.map((number, index) => { let scrollClass = "" if (number === "0") { scrollClass = "numbers-scroll0" + Math.ceil(Math.random * 5) } else { scrollClass = "numbers-scroll" + number } return <div className="numbers-box" key={index}> { showValue > 0 ? <span className={scrollClass} style={this.props.numberStyle}>
                <label>0</label>
                <label>1</label>
                <label>2</label>
                <label>3</label>
                <label>4</label>
                <label>5</label>
                <label>6</label>
                <label>7</label>
                <label>8</label>
                <label>9</label>
                <label>0</label>
              </span> : <span>
                <label>0</label>
              </span> } </div> }) } </div> } }

css3 动画样式：
