vue能循環一個固定變數嘛？
比如說我num=3
我要循環num次
<!DOCTYPE html>
<html lang="en">

<script src="https://unpkg.com/vue@2.3.3"></script>
</head><body>
<p id="app">
<p v-for="n in full"></p>
<p v-if="ishalf"></p>
<p v-for="n in empty"></p>
</p>
<script>
const MAXSIZE = 5;
var vm = new Vue({
el : '#app',
props: {
score:{
type: Number,
defualt: 4.5
}
},
data:{
num : 3
},
created(){
this.full = Math.floor(this.score);
this.ishalf = this.score!=this.full;
this.empty = Math.floor(MAXSIZE-this.score);
}
})
</script>
</body></html>
