下面我就为大家分享一篇vue-star评星组件开发实例，具有很好的参考价值，希望对大家有所帮助。
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>
<p class="star" :class="starsize">
<span v-for="(itemclass,key) in itemclasses" :class="itemclass" class="star-item"></span>
</p>
</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

</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')
上面是我整理给大家的，希望今后会对大家有帮助。
