star文件夹下建立star.vue,及相关的图片信息。便于组件的就近维护

star.vue:

<template>
 <div class="star" :class="starsize">
 <span v-for="(itemclass,key) in itemclasses" :class="itemclass" class="star-item"></span>
 </div>
</template>
<script>
 const length = 5;
 const cls_on = 'on';
 const cls_half = 'half';
 const cls_off = 'off';
 export default{
 props:{
  size:{ //尺寸,24,36,48
  type: number
  },
  score:{
  type: number
  }
 },
 computed:{
  starsize(){
  return 'star-'+ this.size;
  },
  itemclasses(){
  let result = [];
  let score = math.floor(this.score*2)/2; //将数值调整为整数及.5的形式,例:4.3 => 4;4.6 => 4.5
  let hasdecimal = score %1 !==0;
  let integer = math.floor(score);
  for(let i =0;i<integer;i++){
   result.push(cls_on);
  }
  if(hasdecimal){
   result.push(cls_half);
  }
  while(result.length<length){
   result.push(cls_off);
  }
  return result;
  }
 }
 }
</script>
<style lang="stylus" rel="stylesheet/stylus">
@import "../../common/stylus/mixin.styl";
.star
 font-size: 0
 .star-item
 display: inline-block
 background-repeat: no-repeat
 &.star-48
 .star-item
  width: 20px
  height: 20px
  margin-right: 22px
  background-size: 20px 20px
  &.last-child
  margin-right: 0
  &.on
  bg-image('star48_on')
  &.half
  bg-image('star48_half')
  &.off
  bg-image('star48_off')
 &.star-36
 .star-item
  width: 15px
  height: 15px
  margin-right: 6px
  background-size: 15px 15px
  &.last-child
  margin-right: 0
  &.on
  bg-image('star36_on')
  &.half
  bg-image('star36_half')
  &.off
  bg-image('star36_off')
 &.star-24
 .star-item
  width: 10px
  height: 10px
  margin-right: 3px
  background-size: 10px 10px
  &.last-child
  margin-right: 0
  &.on
  bg-image('star24_on')
  &.half
  bg-image('star24_half')
  &.off
  bg-image('star24_off')
</style>

header.vue:

<star :size="48" :score="3.5"></star>
<script>
import star from '../star/star.vue'
export default{
 components:{
 star
 }
}
</script>

mixin.styl:

bg-image($url)
 background-image: url($url + '@2x.png')
 @media (-webkit-min-device-pixel-ratio: 3),(min-device-pixel-ratio:3)
 background-image: url($url + '@3x.png')
