Is it possible to switch a background image without the need for live reloading?

Currently, I am developing an Angular pick-ban overlay for organizing League of Legends tournaments. However, I have stumbled upon some fundamental challenges and am unsure if the task is achievable. My main issue is: Can I dynamically alter the background of a div without requiring a component reload?

Within the pick-ban-component.html file:

<div class="blueTeam">
   <app-player-card *ngFor="let player of blueTeam" [bluePlayer]="player"></app-player-card>
</div>

Inside the pick-ban-component.ts file:

public blueTeam = [{
        name: 'playerOne',
        champion: 'Teemo',
        spells: ['Flash', 'Burn']
    },...
];

Within the player-card.html file:

<div [ngClass]="bluePlayer ? 'bluePlayerCard bluePlayer.champion' : redPlayer ? 'redPlayerCard redPlayer.champion' : 'noSelection'"></div>

In the player-card.css file:

.Teemo {
    background-image: url('../../assets/champions/Teemo_0.jpg') !important;
    background-size: cover;
    background-position: top center;
}...

Each champion is registered in my player-card.css file in the same manner as Teemo. Is there a way to avoid reloading the component when changing playerOne's champion to another one, while still achieving a background change?

Answer №1

To make things easier in your situation, consider updating the following line of code:

<div [ngClass]="bluePlayer ? 'bluePlayerCard bluePlayer.champion' : redPlayer ? 'redPlayerCard redPlayer.champion' : 'noSelection'"></div>

You can change it to:

<div [ngClass]="bluePlayer ? 'bluePlayerCard ' + bluePlayer.champion : redPlayer ? 'redPlayerCard ' + redPlayer.champion : 'noSelection'"></div>

Answer №2

To implement dynamic styling in Angular, you can utilize the ngStyle directive

<div class='DynamicStyle' [ngStyle]="{'background-color': 'blue', 'font-size': '16px'}"></div>
