Angular is set up to showcase every single image that is stored within an array

I am having trouble displaying the images from the "image_url" array using a for loop. The images are not showing up as expected.

Here is the content of the array:
image_url: [
0: "https://xyz/16183424594601618342458.5021539.jpg"
1: "https://xyz/16183424594701618342458.579036.jpg"
2: "https://xyz/16183424594511618342458.4947538.jpg"
3: "https://xyz/16183424594661618342458.566865.jpg" ]

I have assigned this array to this.postImages = res.data.postdata.image_url;

<div class="" *ngFor="let images of postImages">
            <div class="flex items-center justify-between">
                <div class="items-center py-4">
                  <img class="side-image w-56 h-56 mr-4 bg-cover bg-no-repeat border"
                    [src]="images ? images : './assets/profile.svg'">
                </div>
              </div>
        </div>

I cannot figure out why the images are not visible. Can someone please help me understand what I am doing wrong?

Answer №1

It is possible that the first item in the array is a numeric value and the second item is the actual URL. Have you considered trying to access images[1] to see if this returns the desired result? You could also check the compiled HTML to inspect the src attribute and verify the content being displayed.

Answer №2

Ensure to define a variable as a string array or any of the options provided below:

public postImages : any

public postImages : string[];

If there is an issue, it might be related to how the variable is declared, otherwise the code should be functioning correctly.

Answer №3

The issue was fixed after including i=index in my code.

<div class="" *ngFor="let images of postImages; let i = index">
