微信小程序使用template标签实现五星评分功能

<template name="starsTemplate">
 <view class='stars-container'>
  <view class='stars'>
  <block wx:for="{{stars}}" wx:for-item="i" wx:key="position">
   <image wx:if="{{i}}" src='/images/icon/star.png'></image>
    <!-- <image wx:elif="{{i==2}}" src='/images/icon/none-star.png'></image> -->
    <image wx:else src='/images/icon/none-star.png'></image>
  </block>
  </view>
  <text class='star-score'>{{score}}</text>
 </view>
</template>

.stars-container {
 display: flex;
 flex-direction: row;
}
.stars {
 display: flex;
 flex-direction: row;
 height: 17rpx;
 margin-right: 24rpx;

}
.stars image {

}
.star-score {

}

<import src="../stars/stars-template.wxml" /> <!--这里引用模板文件最好使用相对路径-->

<template is="starsTemplate" data="{{stars:stars,score:average}}" /> <!--is指定使用模版的名称-->

function convertToStarsArray(stars) {
 var num = stars.toString().substring(0, 1);
 var array = [];
 for (var i = 1; i <= 5; i++) {
  if (i < num) {
   array.push(1);
  } else {
   array.push(0);
  }
 }
 return array;
}

<import src="stars/stars-template.wxml" />
<view style='margin:100rpx'>
 <template is="starsTemplate" data="{{stars:stars,score:average}}" />
</view>
