我认为你要从html获取价值在完全渲染之前。如果您尝试在按钮单击中打印该值，它将起作用。

I think you are tring to get the value from html before rendering completely. If you try to print the value in a button click, it will works.

取决于您的代码我已经修改了一点。试试下面，它对我有用。

depend on your code I have modified a little.Try the below, it is working for me.

  ngAfterViewInit() {
    console.log("afterinit");
    setTimeout(() => {
      console.log(this.abc.nativeElement.innerText);
    }, 1000);
  }

注意：如果不能正常工作，请增加超时时间再试一次。

Note: If not working, please increase the timeout time and try again.
