Exploring Angular2's DOMContentLoaded Event and Lifecycle Hook

Currently, I am utilizing Angular 2 (TS) and in need of some assistance:

     constructor(public element:ElementRef){}  
     ngOnInit(){
       this.DOMready()
     }  

     DOMready() {
       if (this.element) {
         let testPosition = this.element.nativeElement.getElementsByClassName("_mypost");
         console.log(testPosition);
         for (let i = 0; i < testPosition.length; i++) {
         console.log(testPosition[i]);
         }
     } else {
        setTimeout(this.DOMready, 100)
    }

I am facing the following issues:
1) I am struggling to accurately determine when the document is fully loaded and ready for manipulation (I have tried using Angular 2 lifecycle Hooks without success)
2) When I use console.log(testPosition), it displays a list as expected with a length of 10. However, accessing individual elements such as console.log(testPosition[0]) returns undefined. Additionally, running console.log(testPosition[i]) produces no output.
Thank you in advance)

Answer №1

To interact with the DOM, it is recommended to utilize the following methods:

ngAfterViewInit(){
   this.handleDOMManipulation()
 }

If working with projected content:

ngAfterContentInit(){ // or ngAfterContentChecked
   this.handleDOMManipulation()
 }

There are more efficient techniques available for accessing elements within your view.
