这篇文章主要介绍了vue项目之数量占比进度条实现方式,具有很好的参考价值,希望对大家有所帮助。如有错误或未考虑完全的地方,望不吝赐教
vue数量占比进度条实现
功能说明:
1、点击开始,滚动条自动加;
2、点击停止,滚动条停止加;
封装如下
<template> <div> <div class="progress-bar"> <div class="progress" :style="{ width: progressRatio + '%' }" > {{ surplusProgress }} </div> {{ totalProgress }} </div> {{ surplusProgress }} <button @click="start()">开始</button> <button @click="stop()">停止</button> </div> </template> <script> export default { name: 'index', components: {}, props: { total: { type: Number }, surplus: { type: Number } }, data() { return { totalProgress: 0, surplusProgress: 0, progressRatio: 0, clearInt: null // 定时器名 } }, computed: { // 用于监听两个值同时存在的情况 progress() { const { surplus, total } = this return { surplus, total } } }, watch: { progress(newVal) { this.totalProgress = newVal.total this.surplusProgress = newVal.surplus // 注意这里是当前剩余的值比上总值的一个比例显示 this.progressRatio = (newVal.surplus / newVal.total) * 100 } }, methods: { start() { let _this = this // 增加的值 = 总数量 / 100 let addNum = _this.totalProgress / 100 clearInterval(_this.clearInt) _this.clearInt = setInterval(function () { _this.progressRatio = _this.progressRatio + 1 // 这里剩余的值 必须按照比例去增加 才可以最终到达总值 _this.surplusProgress = ((_this.surplusProgress * 100 + addNum * 100) / 100).toFixed(1) if (_this.progressRatio >= 100) { clearInterval(_this.clearInt) _this.progressRatio = _this.progressRatio _this.surplusProgress = parseInt(_this.surplusProgress) } }, 100) }, stop() { clearInterval(this.clearInt) } } } </script> <style lang="scss" scoped> .progress-bar { width: 500px; height: 30px; color: #000; text-align: center; line-height: 30px; box-sizing: border-box; margin-top: 50px; margin-bottom: 20px; border: 1px solid gray; box-shadow: -1px -1px 1px #000; background: rgb(177, 174, 174); position: relative; .progress { height: 100%; background: #3165c5; color: #fff; overflow: hidden; position: absolute; opacity: 0.5; text-align: center; } } </style>
组件使用
<template> <div class="content-box"> <div class="container"> <Progress :total="total1" :surplus="surplus1" /> <Progress :total="total2" :surplus="surplus2" /> </div> </div> </template> <script> import Progress from '@/components/ProgressBar' export default { name: 'record', components: { Progress }, data() { return { surplus1: 0, total1: 0, surplus2: 0, total2: 0 } }, activated() { let _this = this // 模拟请求情况 setTimeout(() => { _this.surplus1 = 30 _this.total1 = 100 _this.surplus2 = 60 _this.total2 = 220 }, 3000) }, methods: {}, mounted() {} } </script> <style scoped> </style>
效果如下:
遇到问题
在到达终点时,总数和剩余值不一致问题,查明问题原因是小数点的问题,目前保留一位小数点;
vue实现进度条效果
这里实现进度条用到了es6语法的模版字符串,通过更改css样式实现正常显示进度的进度条和一种显示剩余余额的进度条:
html代码不需要改变:
<div class="scheduleCont_1_left_1" :class="10 >= 100 ? 'nobg' : ''"> //10为展示的进度,100为总的进度数量 <div :style="{ width: `${(10 / 100).toFixed(2) * 100}%` }" class="un_xg_1_3_1"></div> </div>
正常显示进度的进度条:
.scheduleCont_1_left_1{ position: relative; width: 100%; height: 0.36rem; background: #E9BBFF; border-radius: 50px; overflow: hidden; .un_xg_1_3_1 { position: absolute; top: 0; left: -1px; width: 0; height: 0.36rem; border-radius: 50px; background-image: linear-gradient(to right, #B72DF7); } }
显示剩余余额的进度条:
.scheduleCont_1_left_1 { position: relative; width: 100%; height: .24rem; background: #ebebeb; border-radius: 50px; overflow: hidden; .un_xg_1_3_1 { float: right; height: .24rem; border-radius: 50px; background-image: linear-gradient(to right, #ff6666); } }
总结
以上为个人经验,希望能给大家一个参考,也希望大家多多支持脚本之家。
