vue实现类似淘宝商品评价页面星级评价及上传多张图片功能

// 评分
 rating: function (index, string) {
  var total = this.stars.length // 星星总数
  var idx = index + 1 // 这代表选的第idx颗星-也代表应该显示的星星数量
  // 进入if说明页面为初始状态
  if (this.scoreStartNum === 0) {
   this.scoreStartNum = idx
   for (var i = 0; i < idx; i++) {
   this.stars[i].src = starOnImg
   this.stars[i].active = true
   }
  } else {
   // 如果再次点击当前选中的星级-仅取消掉当前星级，保留之前的。
   if (idx == this.scoreStartNum) {
   for (var i = index; i < total; i++) {
    if (i != 0) {
    this.stars[i].src = starOffImg
    this.stars[i].active = false
    }
   }
   }
   // 如果小于当前最高星级，则直接保留当前星级
   if (idx < this.scoreStartNum) {
   for (var i = idx; i < this.scoreStartNum; i++) {
    if (i != 0) {
    this.stars[i].src = starOffImg
    this.stars[i].active = false
    }
   }
   }
   // 如果大于当前星级，则直接选到该星级
   if (idx > this.scoreStartNum) {
   for (var i = 0; i < idx; i++) {
    this.stars[i].src = starOnImg
    this.stars[i].active = true
   }
   }

   var count = 0 // 计数器-统计当前有几颗星
   for (var i = 0; i < total; i++) {
   if (this.stars[i].active) {
    count++
   }
   }
   this.scoreStartNum = count
  }
  if (this.scoreStartNum === 1) {
   this.scoreInfo = '很差'
  } else if (this.scoreStartNum === 2) {
   this.scoreInfo = '差'
  } else if (this.scoreStartNum === 3) {
   this.scoreInfo = '一般'
  } else if (this.scoreStartNum === 4) {

<textarea v-bind:maxlength="Surplus" @input="descArea" v-model="inputText" name="abstract" id="abstract" placeholder="宝贝满足你的期待吗？说说你的使用心得，分享给想买的他们吧！"></textarea>

<input type="file" class="input-file" multiple="multiple" name="avatar" ref="avatarInput" @change="changeImage($event)" accept="image/gif,image/jpeg,image/jpg,image/png">

let reader = new FileReader()
   let that = this
   reader.readAsDataURL(file)
   reader.onload = function (e) {
   console.log(this.result)
   that.imgUrls.push(this.result)
   }

<mt-swipe :auto="0" :show-indicators="false" @change="handleChange" :continuous="false" :defaultIndex="num">
   <mt-swipe-item v-for="(item,index) in imgUrls" :key="item.id">
    <div class="num" >{{index+1+'/'+imgUrls.length}}</div>
    <img :src="/UploadFiles/2021-04-02/imgUrls[index]">

:auto="0"为不自动播放，:show-indicators="false"表示不展示下面的圆点，:defaultIndex="num"默认展示第几张图片，:continuous="false" 是否重复播放。
关键代码为：


methods: {
 //拿到图片信息转化为图片流
 changeImage: function (e) {
  if (e.target.files.length <= (this.maxImages - this.imgUrls.length)) {
  for (var i = 0; i < e.target.files.length; i++) {
   let file = e.target.files[i]
   this.file = file
   console.log(this.file)
   let reader = new FileReader()
   let that = this
   reader.readAsDataURL(file)
   reader.onload = function (e) {
   console.log(this.result)
   that.imgUrls.push(this.result)
   }
  }
  // 剩余张数
  this.leftImages = this.maxImages - (this.imgUrls.length + e.target.files.length)
  this.pictureNums = String(this.maxImages - (this.imgUrls.length + e.target.files.length)) + '/' + String(this.maxImages)
  } else {
  Toast('只能选择' + (this.maxImages - this.imgUrls.length) + '张了')
  }
 },
 //删除
 delect (index) {
  this.imgUrls.splice(index, 1)
  this.leftImages++
  console.log('数量' + this.leftImages)
  if (this.leftImages == this.maxImages) {
  this.pictureNums = '上传图片'
  } else {
  this.pictureNums = String(this.leftImages) + '/' + String(this.maxImages)
  }
 },
 //轮播图滑动改变index
 handleChange(index){
  this.num = index
 },
 //看大图
 bigImg (index) {
  this.showBigImg = true
  this.num = index
 }
 }


样式如下


<template>
 <div class="avatar">
  <!--展示图片-->
  <div class="hasPic" v-if="imgUrls.length>0" v-for="(item,index) in imgUrls">
  <img class="seledPic" ref="picture" :src="/UploadFiles/2021-04-02/item">

注意点：
1.项目中用到了mint -ui，转移项目中录播图代码时，会报错，在终端项目中输入：npm i mint-ui -S
 用到了px和rem自动转化  https://www.jb51.net/article/149721.htm
