在NativeScript 6 Angular中无法获取透明WebView (设置backgroundColor transparent & layertype软件)

npm install -g nativescript

tns create my-app-name --ng
cd my-app-name

npm install nativescript-webview-interface --save

import { Component, OnInit } from "@angular/core";
import { WebViewInterface } from 'nativescript-webview-interface';

@Component({
  selector: "my-app",
  template: `
    <GridLayout>
      <WebView #webView></WebView>
    </GridLayout>
  `
})
export class AppComponent implements OnInit {
  private webViewInterface: WebViewInterface;

  constructor() {}

  ngOnInit() {
    const webView = this.webView.nativeElement;
    this.webViewInterface = new WebViewInterface(webView);
  }
}

import { Component, OnInit, ViewChild, AfterViewInit } from "@angular/core";
import { WebViewInterface } from 'nativescript-webview-interface';

@Component({
  selector: "my-app",
  template: `
    <GridLayout>
      <WebView #webView></WebView>
    </GridLayout>
  `
})
export class AppComponent implements OnInit, AfterViewInit {
  @ViewChild("webView", { static: false }) webView;

  private webViewInterface: WebViewInterface;

  constructor() {}

  ngOnInit() {}

  ngAfterViewInit() {
    const webView = this.webView.nativeElement;
    this.webViewInterface = new WebViewInterface(webView);

    this.webViewInterface.callJSFunction(`
      document.body.style.backgroundColor = 'transparent';
      document.body.style.setProperty('-webkit-backdrop-filter', 'blur(10px)');
    `);
  }
}
