Navigating through Array Elements with ngFor and the Next Button

Just diving into the world of Ionic 3 - I'm interested in using ngFor to loop through an array. So far, I've managed to display one item at a time using the slice method. Now, I want to be able to move on to the next item in the array when the user clicks the "Next" button.

<div *ngFor="let reference of content | slice:0:1;">
<div> {{reference.item}} </div>
<div> {{reference.image}} </div>
<div> {{reference.field2}} </div>

<button ion button> Next </button>

I'm unsure if ngFor is the best solution for this task or if there might be a more efficient alternative. Any suggestions are greatly appreciated!

Answer №1

To avoid displaying all data as a list, you can skip using ngFor in this scenario. Instead, you can simply display the data by specifying the index that will increase with each click of the next button.

reference:any;
currentIndexToShow:number = 0;

nextButtonClick() {

   this.currentIndexToShow++;
   this.reference = content[currentIndexToShow];

}

<div> {{reference?.item}} </div>
<div> {{reference?.image}} </div>
<div> {{reference?.field2}} </div>
