ModalService
ModalService
This service is responsible for instantiating a ModalDialog component and embedding the specified component within.
class ModalService {
constructor(overlayHostService: OverlayHostService)
fromComponent(component: Type<T> & Type<Dialog<R>>, options?: ModalOptions<T>) => Observable<R | undefined>;
dialog(config: DialogConfig<T>) => Observable<T | undefined>;
}
constructor
(overlayHostService: OverlayHostService) => ModalService
fromComponent
(component: Type<T> & Type<Dialog<R>>, options?: ModalOptions<T>) => Observable<R | undefined>
Create a modal from a component. The component must implement the Dialog interface. Additionally, the component should include templates for the title and the buttons to be displayed in the modal dialog. See example:
Example
class MyDialog implements Dialog {
resolveWith: (result?: any) => void;
okay() {
doSomeWork().subscribe(result => {
this.resolveWith(result);
})
}
cancel() {
this.resolveWith(false);
}
}
Example
<ng-template vdrDialogTitle>Title of the modal</ng-template>
<p>
My Content
</p>
<ng-template vdrDialogButtons>
<button type="button"
class="btn"
(click)="cancel()">Cancel</button>
<button type="button"
class="btn btn-primary"
(click)="okay()">Okay</button>
</ng-template>
dialog
(config: DialogConfig<T>) => Observable<T | undefined>
Displays a modal dialog with the provided title, body and buttons.
Dialog
Any component intended to be used with the ModalService.fromComponent() method must implement this interface.
interface Dialog<R = any> {
resolveWith: (result?: R) => void;
}
resolveWith
(result?: R) => void
Function to be invoked in order to close the dialog when the action is complete. The Observable returned from the .fromComponent() method will emit the value passed to this method and then complete.
DialogConfig
Configures a generic modal dialog.
interface DialogConfig<T> {
title: string;
body?: string;
translationVars?: { [key: string]: string | number };
buttons: Array<DialogButtonConfig<T>>;
size?: 'sm' | 'md' | 'lg' | 'xl';
}
title
string
body
string
translationVars
{ [key: string]: string | number }
buttons
Array<DialogButtonConfig<T>>
size
'sm' | 'md' | 'lg' | 'xl'
ModalOptions
Options to configure the behaviour of the modal.
interface ModalOptions<T> {
size?: 'sm' | 'md' | 'lg' | 'xl';
verticalAlign?: 'top' | 'center' | 'bottom';
closable?: boolean;
locals?: Partial<T>;
}
size
'sm' | 'md' | 'lg' | 'xl'
Sets the width of the dialog
verticalAlign
'top' | 'center' | 'bottom'
Sets the vertical alignment of the dialog
closable
boolean
When true, the "x" icon is shown and clicking it or the mask will close the dialog
locals
Partial<T>
Values to be passed directly to the component being instantiated inside the dialog.
