Here is my full implementation of modal bootstrap angular2 component:
I assume that in your main index.html file (with <html> and <body> tags) at the bottom of <body> tag you have:
<script src="assets/js/jquery-2.1.1.js"></script>
<script src="assets/js/bootstrap.min.js"></script>
modal.component.ts:
import { Component, Input, Output, ElementRef, EventEmitter, AfterViewInit } from '@angular/core';
declare var $: any;// this is very importnant (to work this line: this.modalEl.modal('show')) - don't do this (becouse this owerride jQuery which was changed by bootstrap, included in main html-body template): let $ = require('../../../../../node_modules/jquery/dist/jquery.min.js');
@Component({
selector: 'modal',
templateUrl: './modal.html',
})
export class Modal implements AfterViewInit {
@Input() title:string;
@Input() showClose:boolean = true;
@Output() onClose: EventEmitter<any> = new EventEmitter();
modalEl = null;
id: string = uniqueId('modal_');
constructor(private _rootNode: ElementRef) {}
open() {
this.modalEl.modal('show');
}
close() {
this.modalEl.modal('hide');
}
closeInternal() { // close modal when click on times button in up-right corner
this.onClose.next(null); // emit event
this.close();
}
ngAfterViewInit() {
this.modalEl = $(this._rootNode.nativeElement).find('div.modal');
}
has(selector) {
return $(this._rootNode.nativeElement).find(selector).length;
}
}
let modal_id: number = 0;
export function uniqueId(prefix: string): string {
return prefix + ++modal_id;
}
modal.html:
<div class="modal inmodal fade" id="{{modal_id}}" tabindex="-1" role="dialog" aria-hidden="true" #thisModal>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header" [ngClass]="{'hide': !(has('mhead') || title) }">
<button *ngIf="showClose" type="button" class="close" (click)="closeInternal()"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<ng-content select="mhead"></ng-content>
<h4 *ngIf='title' class="modal-title">{{ title }}</h4>
</div>
<div class="modal-body">
<ng-content></ng-content>
</div>
<div class="modal-footer" [ngClass]="{'hide': !has('mfoot') }" >
<ng-content select="mfoot"></ng-content>
</div>
</div>
</div>
</div>
And example of usage in client Editor component:
client-edit-component.ts:
import { Component } from '@angular/core';
import { ClientService } from './client.service';
import { Modal } from '../common';
@Component({
selector: 'client-edit',
directives: [ Modal ],
templateUrl: './client-edit.html',
providers: [ ClientService ]
})
export class ClientEdit {
_modal = null;
constructor(private _ClientService: ClientService) {}
bindModal(modal) {this._modal=modal;}
open(client) {
this._modal.open();
console.log({client});
}
close() {
this._modal.close();
}
}
client-edit.html:
<modal [title]='"Some standard title"' [showClose]='true' (onClose)="close()" #editModal>{{ bindModal(editModal) }}
<mhead>Som non-standart title</mhead>
Some contents
<mfoot><button calss='btn' (click)="close()">Close</button></mfoot>
</modal>
Ofcourse title, showClose, mhead and mfoot ar optional parameters.
[hidden]in the modal ?
