Dependencies

• Angular 4+
• Bootstrap 4+

Installation

Install above dependencies via npm.

Now install ngx-multi-modal via:

npm install --save ngx-multi-modal

SystemJS

Note:If you are using SystemJS, you should adjust your configuration to point to the UMD bundle. In your systemjs config file, map needs to tell the System loader where to look for ngx-multi-modal:

map: {
  'ngx-multi-modal': 'node_modules/ngx-multi-modal/bundles/ngx-multi-modal.umd.js',
}

Once installed you need to import the main module:

import { NgxMultiModalModule } from 'ngx-multi-modal';

The only remaining part is to list the imported module in your application module. The exact method will be slightly different for the root (top-level) module for which you should end up with the code similar to (notice NgxMultiModalModule .forRoot()):

import { NgxMultiModalModule } from 'ngx-multi-modal';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [NgxMultiModalModule.forRoot(), ...],  
  bootstrap: [AppComponent]
})
export class AppModule {
}

In the root level you can specify base settings to all modals inside app providing them to forRoot method.

import { NgxMultiModalModule } from 'ngx-multi-modal';

@NgModule({
  declarations: [AppComponent, ...],
  imports: [
    NgxMultiModalModule.forRoot(
      {
        backdrop: false, // Whether a backdrop element should be created for a given modal (true by default)
        container: '#modal_container', // CSS selector of an element to which to attach newly opened modal windows ('body' by default)
        size: 'lg', // Size of a new modal window.
        keyboard: false, // Whether to close the modal when escape key is pressed (true by default).
        windowClass: '' // Custom class to append to the modal window
      }
    )],  
  bootstrap: [AppComponent]
})
export class AppModule {
}

Other modules in your application can simply import NgxMultiModalModule:

import { NgxMultiModalModule } from 'ngx-multi-modal';

@NgModule({
  declarations: [OtherComponent, ...],
  imports: [NgxMultiModalModule, ...], 
})
export class OtherModule {
}

Example

For detailed usage examples see demo app code.

Usage

To use modals you have to inject NgxModalStack service.

constructor(public modalService: NgxModalStack);

Via NgxModalStack service you gain full control over Modal Stack.

You have three ways to open modal dialogs:

/**
* data: string - plain string which will be shown inside modal
* options: NgxModalOptions (see NgxModalOptions interface for details)
*/
let ngxStringModal: StringModalRef = this.modalService.openFromString(data, this.options);

/**
* template - reference to ng-template
* context - template context, should be used inside ng-template via let-* syntax
* options: NgxModalOptions (see NgxModalOptions interface for details)
*/
let ngxTemplateModal: TemplateModalRef = this.modalService.openFromTemplate(template, context, this.options);
// Template context can be accessed via 
ngxTemplateModal.context;

/**
* TestModalComponent - component class (don't forget to register component inside ngModules entryComponents)
* options: NgxModalOptions (see NgxModalOptions interface for details)
*/
let ngxComponentModal: ComponentModalRef = this.modalService.openFromComponent(TestModalComponent, this.options);
// Component instance can be accessed via 
ngxComponentModal.instance;
