如何从接口外部访问变量。在这个Example2代码中,我期望得到与Example1相同的结果。建议我怎么做?
// Example 1
class Sample1{
data?:string;
}
const d1 = new Sample1()
d1.data = "hai"
console.log(d1)// Result Sample1 { data: 'hai' }
// Example 2
interface Sample2{
dat1?:any;
}
class Sample3 implements Sample2{
dat1:any
constructor(dat1:Sample2){
this.dat1 = dat1
}
}
const d2 = new Sample3({dat1:"hai"})
console.log(d2) // Sample3 { dat1: { dat1: 'hai' } }
最佳答案

使用价差运算符:
// Example 2
interface Sample2{
dat1?:any;
}
class Sample3 implements Sample2{
dat1:any
constructor(dat:Sample2){
this.dat1 = {...dat}
}
}
const d2 = new Sample3({dat1:"hai"})
