Question

在加载仪表板期间（在Chrome上运行）我在IE / Firefox上工作时遇到问题。
使用其他浏览器（例如Chrome）加载页面时，页面未加载。
该问题似乎与以下代码 ColorScale.js.pre-build-optimizer.js 有关：

  /**
   * Setup color scale properties
   * @param {Object} props - The properties to initialize the color scale
   * @param {Array} props.colors - The array of colors
   */
  constructor(props) {
    props = {
      ...props
    };
    this.length = props.length || 15;
    this.colors = props.colors || this.generateColorMatrix(this.length);
  }

如果我收到了“ ... props”，则与IE或类似内容不兼容。仪表板以这种方式启动：

ng serve --host 0.0.0.0 --port 443 --public-host IP-ADDR --ssl --ssl-key /run/secrets/dashboard.key --ssl-cert /run/secrets/dashboard.cert --proxy-config server.js --prod

，它基于以下模块：

我在index.html页面中放置了以下元数据：

<!doctype html>

</head>
<body class="light">
  <app-root></app-root>  
</body>
</html>

控制台输出打印：

 HTML1300: Navigation occurred.

Answer 1

constructor()是es6的es6语法，在IE 11中为not supported。您需要添加polyfill以使angular app与IE 11兼容。您可以参考this thread。

此外，从控制台中的错误消息来看，似乎您使用的是IE 11的not supported的webp图像。您还需要使用polyfill。您可以使用webp-hero来填充以在IE中呈现Webp图像。

角度应用程序不适用于IE / Firefox
