Question

我有一个班级

Test.ts：

class Test
{
     public property1: string;
     public property2: boolean;
     constructor(property1, property2)
     {
            this.property1 = property1;//will get value while instantiation
            this.property2 = property2;//will get value while instantiation
            this.property3 = somevalue;//want to add fake value here 
     }
}

如上所述，我想为property3提供假值但property1和property2我将从实例化中获取它。我怎样才能做到这一点？

Answer 1

我相信你正在努力宣布property3成员。就像你宣布其他属性一样。如果您需要，可以使用属性初始值设定项：

class Test
{
     public property1: string;
     public property2: boolean;
     public property3 = somevalue;
     constructor(property1, property2)
     {
            this.property1 = property1;//will get value while instantiation
            this.property2 = property2;//will get value while instantiation
     }
}
