Momentjs with Typescript : "type string is not assignable to type 'Date'"
提问by undefined
Till now I was using momentjs library like this:
到目前为止，我一直在使用这样的 momentjs 库：
import * as moment from 'moment'; // import moment.
@Component({..});
export class TestClass {
lastUpdated = Date
constructor(private myService: MyService){
this.lastUpdated = this.getCurrentTime(); **// this shows error.. that type string is not assignable to type 'Date'**
}
var getCurrentTime(){
return moment().format('DD MMM YYYY HH:mm:ss');
}
}
Above code shows me this error: that type string is not assignable to type 'Date'**
上面的代码向我显示了这个错误：该类型字符串不可分配给类型 'Date'**
But same code exactly working fine when I use this line in place of the import module, evenn other resturent os
但是当我使用这一行代替导入模块时，相同的代码完全正常工作，甚至其他餐厅操作系统
declare var moment: any;
声明 var 时刻：任何；
But I canot use above statement as it is using "var": and 'any' is not suggested by Lint.
但是我不能使用上面的语句，因为它使用的是“var”：并且 Lint 不建议使用“any”。
Why getCurrentTime is returning String? Should not this return Date
为什么 getCurrentTime 返回 String？应该不是这个返回日期

“type string is not assignable to type 'Date'”
“类型字符串不能分配给类型'日期'”
lastUpdated = Dateshould be lastUpdated: string.
lastUpdated = Date应该是lastUpdated: string。

Fixed a few other things as well:
还修复了其他一些问题：
import * as moment from 'moment'; // import moment.
@Component({..});
export class TestClass {
lastUpdated: string;
constructor(private myService: MyService){
this.lastUpdated = this.getCurrentTime();
}
getCurrentTime(){
return moment().format('DD MMM YYYY HH:mm:ss');
}
}

Can avoid calling one more function by the below code
可以避免通过下面的代码再调用一个函数
import * as moment from 'moment'; // import moment.
@Component({..});
export class TestClass {
lastUpdated: string;
constructor(private myService: MyService){
this.lastUpdated = moment(this.lastUpdated).format('DD MMM YYYY HH:mm:ss');
}
}
