错误TS2322:类型'()=>字符串"不可分配给“字符串"类型

问题描述：

我是Angular 6的新手.使用以下代码:

I am new to Angular 6. With the following code:

export class DateComponent implements OnInit {

  currentDate: string = new Date().toDateString;

  constructor() { }

  ngOnInit() {
  }
}

我遇到以下错误，但我不知道是什么原因引起的.

I am getting the following error, but I do not know what may be causing it.

错误TS2322:类型'()=>字符串'不能分配给类型'字符串'.

error TS2322: Type '() => string' is not assignable to type 'string'.

答

您应调用函数，而不要分配函数对象.最后添加()应该可以解决

You should invoke the function, not assign the function object. Adding () at the end should fix it

currentDate: string = new Date().toDateString();
