Angular2和TweenMax - 无法在'窗口'上执行'scrollTo'：参数1（'选项'）不是对象

我有一些问题。我想创建按钮，将整个页面滚动到顶部。这是我的代码。Angular2和TweenMax - 无法在'窗口'上执行'scrollTo'：参数1（'选项'）不是对象

app.component.html

<p>lorem...</p> <!-- 100 times --> 
<div (click)="scroll()">Scroll to top</div>

app.component.ts

import { TabHeaderComponent } from './components/tab/tab-header/tab-header.component'; 
import { Component, OnInit } from '@angular/core'; 
import { TweenLite } from 'gsap'; 
import ScrollToPlugin from "gsap/ScrollToPlugin"; 

@Component({ 
    selector: 'app-root', 
    templateUrl: './app.component.html', 
    styleUrls: ['./app.component.sass'] 
}) 
export class AppComponent implements OnInit { 

    constructor() {} 
    ngOnInit(): void {} 


    public scroll() { 
    TweenLite.to(window, 1, { 
      scrollTo: 0 
    }); 
    } 
}

的package.json

无法执行“scrollTo”上“窗口”：参数1（“选项”）是不是一个对象

你知道，怎么了？任何想法？

哦，我已经找到了解决方案！它非常简单。只需将window更改为document.body即可。这是一个例子。

滚动（）函数

public scroll() { 
    // can you tell me why 'document.body.scrollTop' is always equals to 0 
    // in Chrome ??? 
    if(document.body.scrollTop !== 0) { 
     TweenLite.to(document.body, 1, {scrollTop: 0}); 
    } 
    else { 
     TweenLite.to(document.documentElement, 1, {scrollTop: 0}); 
    } 
}

我希望它能帮助
