type x与type缺少以下属性，但这两个type值是不同的类型

Question

type _VariableTypes = "propertyA"|"propertyB"
interface _VariableValues {
propertyA?: {
value: string
type: "INCLUDE"|"EXCLUDE"
}
propertyB?: {
value: number
type: "INCLUDE"|"EXCLUDE"
}
}
class Achievement {
private Data:_VariableValues
constructor () {
this.Data = {}
}
addVariable ( type:_VariableTypes, value:_VariableValues ) {
this.Data[type] = value
}
}

(parameter) type: _VariableTypes
Type '_VariableValues' is not assignable to type '{ value: string; type: "INCLUDE" | "EXCLUDE"; } & { value: number; type: "INCLUDE" | "EXCLUDE"; }'.
Type '_VariableValues' is missing the following properties from type '{ value: string; type: "INCLUDE" | "EXCLUDE"; }': value, typets(2322)

我不知道为什么这会给我一个错误，我使用的是相同的类型，但它说缺少了一些东西。我尝试将interface更改为type，但它无法解决错误

Answer 1

可以用这种方法解决。

type Propertytypes = "propertyA"|"propertyB"
type Type = "INCLUDE" | "EXCLUDE"
type VariableTypeA = {
value: string,
type: Type
}
type VariableTypeB = {
value: number,
type: Type
}
type VariableTypes = VariableTypeA | VariableTypeB
type DataType = Record<Propertytypes, VariableTypes>
class Achievement {
private Data: DataType
constructor () {
this.Data = {} as DataType
}
addVariable ( type: Propertytypes, value: VariableTypes ) {
this.Data[type] = value
}
}
