I am trying to display a random array of images in the UI, but I'm encountering an error with innerHTML when using the code below in TypeScript.
randomPic(){
this.randomNum= Math.floor(Math.random() * this.myPix.length);
console.log(this.randomNum)
return document.getElementById('myPicture').innerHTML= '<img src="'+this.myPix[randomNum]+'" />';
}
Could someone please assist me in identifying where I may be going wrong?
Avoid using document.getElementById within an angular environment. It is preferable to achieve your desired outcome by connecting data from your component to your template (and vice versa).
import { Component } from '@angular/core';
@Component({
selector: 'app-foobar',
template: `
<img [src]="myPix[randomNumber]" />
`,
})
export class FoobarComponent {
readonly myPix = [
'https://via.placeholder.com/150',
'https://via.placeholder.com/200',
'https://via.placeholder.com/350',
'https://via.placeholder.com/400',
];
randomNumber = Math.floor(Math.random() * this.myPix.length);
}
In the above example, we utilize property binding ([src]).
