本文实例讲述了微信小程序实现的五星评价功能。分享给大家供大家参考，具体如下：

实现五星评价功能，效果图如下：

.wxml文件：

<view class="star-title">1、品质效果</view><view class="star-pos"> <image class='stars' bindtap="changeColor" data-index='0' data-no="{{item}}" wx:for="{{stardata}}" src="{{flag[0]>=item? '../../images/icon/star1.png': '../../images/icon/star0.png'}}" /> <view style='margin-left: 30rpx;'>{{startext[0]}}</view></view><view class="star-title">2、服务质量</view> <view class="star-pos"> <image class='stars' bindtap="changeColor" data-index='1' data-no="{{item}}" wx:for="{{stardata}}" src="{{flag[1]>=item? '../../images/icon/star1.png': '../../images/icon/star0.png'}}" /> <view style='margin-left: 30rpx;'>{{startext[1]}}</view></view><view class="star-title">3、综合管理</view><view class="star-pos"> <image class='stars' bindtap="changeColor" data-index='2' data-no="{{item}}" wx:for="{{stardata}}" src="{{flag[2]>=item? '../../images/icon/star1.png': '../../images/icon/star0.png'}}" /> <view style='margin-left: 30rpx;'>{{startext[2]}}</view></view>

.js 文件：

page: ({ data: { flag:[0, 0, 0], startext: ['', '', ''], stardata: [1, 2, 3, 4, 5], }, // 五星评价事件 changeColor: function (e) { var index = e.currentTarget.dataset.index; var num = e.currentTarget.dataset.no; var a = 'flag[' + index + ']'; var b = 'startext[' + index + ']'; var that = this; if(num == 1) { that.setData({ [a]: 1, [b]: '非常不满意' }); } else if (num == 2){ that.setData({ [a]: 2, [b]: '不满意' }); } else if (num == 3) { that.setData({ [a]: 3, [b]: '一般' }); } else if (num == 4) { that.setData({ [a]: 4, [b]: '满意' }); } else if (num == 5) { that.setData({ [a]: 5, [b]: '非常满意' }); } },})

.wxss文件：

.star-pos { margin: 10rpx; display: flex; flex-direction: row;}.stars{ width: 40rpx; height: 40rpx; margin-left: 30rpx;}

希望本文所述对大家微信小程序开发有所帮助。
