How to add a loading spinner to an Angular Material button (Step-by-step Guide)
24. Oct. 2020
The 2 minute complete guide to adding a loading spinner to the Angular Material Button
Say, wouldn't it be dandy if the Angular Material button had a loading state option?
Err…
…wouldn't it be nice if Angular Material had a button with a loading spinner?
Like maybe a CSS class or attribute that we could add to put our material button into a loading state?
Instead of ranting I decided to try to build my own solution - and succeeded!
With no further ado, I've included the code below.
Our spinner (CSS).
@keyframes spinner {
to {transform: rotate(360deg);}
}
.spinner:before {
content: '';
box-sizing: border-box;
position: absolute;
top: 50%;
left: 50%;
width: 20px;
height: 20px;
margin-top: -10px;
margin-left: -10px;
border-radius: 50%;
border: 2px solid #ffffff;
border-top-color: #000000;
animation: spinner .8s linear infinite;
}Our button (HTML).
<div style="text-align:center">
<button mat-raised-button color="primary" [class.spinner]="loading" [disabled]="loading" (click)="save()">Save</button>
</div>Our .ts file (the logic)
export class AppComponent{
title = 'hello-world';
loading = false;
save(): void {
this.loading = true;
}
}Done!
I told you this was simple. You're welcome. Hope you enjoyed it!
