Mobiscroll Instance

When a mobiscroll component is initialized, an instance of the component is created. Through the instance you have access to all methods and properties of the component.

There are multiple ways to access the instance of an individual component.

1. Inside events

The mobiscroll instance is passed as parameter for every event of the component.

@Component({
    selector: 'my-example',
    template: `<input [(ngModel)]="birthday" mbsc-calendar [mbsc-options]="settings" />`
})
export class MyExampleComponent {
    birthday: Date = new Date();
    settings: MbscCalendarOptions = {
        onSet: (event, inst) => {
            const selectedDate = inst.getVal(); // Call the getVal method
        }
    };
}

@Component({
    selector: 'my-inline-example',
    template: `<mbsc-calendar [(ngModel)]="birthday" (onSet)="mySend($event)" />`
})
export class MyExampleComponent {
    birthday: Date = new Date();
    mySend(event: any) {
        const selectedDate = event.inst.getVal(); // Call the getVal method
    }
}

2. Using the instance property of the exported class

The mobiscroll directives and components are exported as 'mobiscroll' for template variables. Every exported object has an 'instance' property.

<mbsc-popup #myPopup="mobiscroll">
    <p>Here is the popup content</p>
</mbsc-popup>
<mbsc-button (click)="myPopup.instance.show()">Show My Popup</mbsc-button>

3. Through active instance

Stores the currently active mobiscroll instance (expcept inline instances), or null if there is no active instance.

mobiscroll.activeInstance

Setting options dynamically

There are two ways to modify options after initalization

1. Using the option method.
   
   The option method always triggers reinitialization. Most of the settings can be updated only this way, updating without initialization has no effect, because the markup is already generated. If the scroller was visible, the reinitialization hides it and it's not shown again automatically (except in inline display mode).
   
   
   Here is an example for the dynamic option change

   import { ViewChild } from '@angular/core';
   @Component({
       selector: 'my-example',
       template: `
           <input mbsc-scroller #myVariable="mobiscroll" [(ngModel)]="myExample"/>
           <button (click)="changeOptions()">Change theme and language</button>
       `
   })
   export class MyExample {
       @ViewChild('myVariable') 
       myRef: any;
   
       // Modify options
       changeOptions() {
           this.myRef.instance.option({
               theme: 'mobiscroll',
               lang: 'de'
           });
       }
   }

2. Modify directly the settings object.
   
   Useful when changing dynamic settings, which do not need redraw (e.g. readonly, calendar marked days).
   
   
   Example

   import { ViewChild } from '@angular/core';
   @Component({
       selector: 'my-example',
       template: `
           <input mbsc-scroller #myVariable="mobiscroll" [mbsc-options]="myOptions"/>
           <button (click)="changeOptions()">Change readonly</button>
       `
   })
   export class MyExample {
       @ViewChild('myVariable') 
       myRef: any;
   
       // get instance and modify a setting
       changeOptions() {
           this.myRef.instance.settings.readonly = true;
       }
       
       // Modify settings in an event
       myOptions: any = {
           onBeforeShow: (event, inst) => {
               inst.settings.readonly = true;
           }
       }
   }
