无法绑定到＆＃39;查看＆＃39;因为它不是“div”的已知属性。 Ionic3

Question

我是Ionic的新手，我正在尝试在我的Ionic3应用程序中使用Angular Calendar。但它引起了一个错误说明，

无法绑定到＆＃39;查看＆＃39;因为它不是“div”的已知属性。屏幕截图为enter image description here

这是我的app.module文件

＆＃13;

＆＃13;

我的typecscript看起来像这样

＆＃13;

＆＃13;

  activeDayIsOpen: boolean = true;
  
  ngOnInit() {

  }

＆＃13;

＆＃13;

最后我的组件如下所示：

＆＃13;

＆＃13;

        (viewDateChange)="activeDayIsOpen = false">

＆＃13;

＆＃13;

现在，当我渲染组件时，它给出了错误：

Can't bind to 'view' since it isn't a known property of 'div'. ("
        class="btn btn-primary"
        mwlCalendarPreviousView
        [ERROR ->][view]="view"
        [(viewDate)]="viewDate"
        (viewDateChange)="activeDayIsOpen = false">
"): ng:///CalendarnewPageModule/CalendarnewPage.html@24:8

有什么我可能错过的东西。请帮忙。

Answer 1

看起来您正在尝试使用属性绑定。在属性绑定中，您只能绑定该元素上存在的属性。由于view不是div的属性，即<div class="my-class" view="my-view"></div>（div标签上的视图无效html），它将抛出此错误。

documentation建议使用<button>。

Answer 2

您需要添加

/* angular-cli file: src/styles.css */
@import "../node_modules/angular-calendar/css/angular-calendar.css";

这不是自动完成的，angular.json 中的样式条目可能会以某种方式被覆盖，
