实现某组件传入 prop 需要校验，该校验依赖于传入的其他 props：
方案如下：
class Validator {
constructor(min, max) {
this.min = min
this.max = max
}
validator(val) {
return val <= this.max && (this.max - this.min) % val === 0
}
}
const validator = new Validator()
export default {
name: 'Home',
props: {
min: {
default: 0,
validator: val => {
validator.min = val
return typeof val === 'number'
}
},
max: {
default: 100,
validator: val => {
validator.max = val
return typeof val === 'number'
}
},
step: {
type: Number,
default: 1,
validator: val => validator.validator(val)
}
}
}
