Angular2和TweenMax - 無法在'窗口'上執行'scrollTo'：參數1（'選項'）不是對象

我有一些問題。我想創建按鈕，將整個頁面滾動到頂部。這是我的代碼。Angular2和TweenMax - 無法在'窗口'上執行'scrollTo'：參數1（'選項'）不是對象

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

無法執行「scrollTo」上「窗口」：參數1（「選項」）是不是一個對象

你知道，怎麼了？任何想法？

哦，我已經找到了解決方案！它非常簡單。只需將window更改爲document.body即可。這是一個例子。

滾動（）函數

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}); 
    } 
}

我希望它能幫助
