Ionic 3 Highcharts不可见

标签： highcharts ionic3 angular2-highcharts

我的应用程序中有以下流程：

firstpage - ＆gt; secondpage（包含高图） - ＆gt; thirdpage - ＆gt; fourthpage - ＆gt; secondpage

当我从firstpage转到secondpage时，图表可见。此外，当我从thirdpage返回secondpage时，我可以看到图表。但是当我从fourthpage转到secondpage时。图表不再存在了。图表的数据是静态的，它没有任何依赖关系：

...
import * as HighCharts from 'highcharts';

@Component({
   ...
})
export class SecondPage {
  ...

  constructor(...) {
   ...
  }

  ionViewDidLoad() {
    console.log('ionViewDidLoad SecondPage');
      this.myChart = HighCharts.chart('container', {
        chart: {
          type: 'line'
        },
        title: {
          text: 'Finanzplan 5 Jahre Mietdauer'
        },
        xAxis: {
          categories: ['1', '2', '3', '4', '5' ]
        },
        yAxis: {
          title: {
            text: 'Euro'
          }
        },
        series: [
          {
            name: 'Jane',
            data: [1, 0, 4]
          },
          {
            name: 'John',
            data: [5, 7, 3]
          }
        ]
      });
  }

}

来自firstoage和fourthpage的来电相同：

this.navCtrl.push(SecondPage);

对于从firstpage到secondpage的来电，我得到：

1 个答案:

答案 0 :(得分：0)

我使用双div containers解决了问题，方法是在到达secondPage之后从调用堆栈中删除thirdPage：

this.navCtrl.remove(this.navCtrl.last().index);

现在它有效......：）
