离子4侧菜单不更新其内容

Question

我已经创建了一个离子4应用程序。

• 我正在使用本地谷歌地图和自定义标记。
• 当我点击一个标记时，我想打开边菜单上的位置详细信息.

我所做的，

- I have disabled the menu at first on app.component.ts
- When ionViewWillEnter() on Map Tab, I have disabled the side-menu
- When ionViewWillLeave() on Map Tab, I have disabled the side-menu
- Side-menu only will enable when to click on the place marker
- I have triggered the event when clicking on place marker
- This event carries the data of place
- I have used the variable 'business' to fill the side-menu
- I have subscribed the event on app.component.ts and assign the 
place data to 'business' variable

问题：-

• 我的边菜单不更新它的内容当我点击标记
• 当我在选项卡之间切换时更新，我想当刷新选项卡

时

“业务”变量的数据更新了吗？如果是这样，也许您可以尝试在ngzone中运行赋值代码。

// import zone in your app.component.ts
import { NgZone } from '@angular/core';
// add zone provider to the component constructor
  constructor(private zone: NgZone) {
   // ...
  }

// cath click event, then
this.zone.run(() => { 
// update data here
});
