Computed property “value1“ was assigned to but it has no setter.

在写 Vue 项目时出现了以上报错信息，特此记录

computed: {value1() {return this.value},
}

意思是说：我在计算属性里修改 value1 这个属性时，没有使用 setter ，导致报错

改成以下写法即可

computed: {value1: {get() {return this.value},set(value) {}},
}

此时属性值已不再是函数写法，变成了对象，其中必须包含 getter 和 setter 两个方法
我使用 getter 先获取到了传过来的 value 值，然后当 value 值发生变化后，由 setter 方法时时改变 value1 的值
