Vue computed 传参
参考文章:vue computed传参
✅ 计算属性不能直接传参
✅ 计算属性传参需要返回一个函数实现 (而不是单单返回一个值),通过调用返回的函数,传入具体参数来计算返回数据
export default {
data () {
return {}
},
computed: {
test() {
return function(index){
return this.data[index].num
}
}
}
}
// computed() 里的写法
const isIconActive = computed(() => (id: number) => (id === currentIconId.value))
