Spinner

AspNet Zero uses ngx-spinner for blocking the UI elements and showing loading effect.

Enable/Disable Full Screen Spinner

To block entire screen, you can use spinner service.

export class DemoUiComponentsComponent extends AppComponentBase implements OnInit {
    constructor(
        injector: Injector
    ) {
        super(injector);
    }
    ngOnInit(): void {
        //show default spinner which cover all page
        this.spinnerService.show();

        setTimeout(() => {
            this.spinnerService.hide();
        }, 1000);
    }
}

Enable/Disable Spinner on Html Elements

To use spinner on specific html elements you can use busyIf directive.

The element which has busyIf directive will be blocked until input is false.

 <div class="kt-portlet kt-portlet--height-fluid">   
     ...
     <div class="kt-portlet__body">
		<div [busyIf]="loading">
            
         </div>
     </div>
     ...
</div>
export class MyComponent extends AppComponentBase implements OnInit {
    constructor(
        injector: Injector
    ) {
        super(injector);
    }
    loading = true;
    ngOnInit(): void {
        setTimeout(() => {
            loading = false;
        }, 3000);
    }
}

Customize Spinner

Since AspNet Zero uses ngx-spinner, you can customize your spinner.

Implementations are located in busy-if.directive.ts and root.component.ts.

Check ngx-spinner documentation for more details.
