Using Angular Ionic for a click event that is triggered by a specific class

I am utilizing Highcharts and would like to click on the legend upon loading.

With the use of Angular Ionic, how can I trigger a click on the .highcharts-legend-item class within the ngOnInit() {} method?

I am aiming to click on this class as soon as the page loads using Angular Ionic.

In JavaScript, you can achieve this with

$(.highcharts-legend-item).click();
, but I am unsure about how to do it in Angular Ionic.

Answer №1

When working with Ionic, you are still operating within a browser environment, allowing you to utilize the standard HTML-JS API.

An Approach Using Pure JavaScript

document.querySelector('.highcharts-legend-item').click()

Utilizing Angular Framework

To interact with elements programmatically, use ElementRef.

TypeScript Code:

 constructor(private elem: ElementRef){}

 ngAfterViewInit(){
    this.elem.nativeElement.querySelector('.highcharts-legend-item').click();
 }
