being a newbie to the angular 6 I am having a issue in passing data from one component to another component.
Actually i am opening child component bootstrap modal from parent modal and want to pass string parameter to child modal component and also want to call function as soon as modal opens and functions returns a array which is shown in table only.
Parent Component HTML
<div class="parent-comp">
<div id="ext-modal" class="modal fade" role="dialog">
<!-- Modal content Starts-->
<app-f-ext [Id]="Id"></app-f-ext>
<!-- Modal content Ends-->
</div>
</div>
Child component TS
import { Component, Input } from '#angular/core';
#Component({
selector: 'app-premium-extension',
templateUrl: './premium-extension.component.html',
styleUrls: ['./premium-extension.component.css']
})
export class ExtensionComponent implements OnInit {
#Input() Id: string;
constructor() {
}
ngOnInit() {
}
callThisFunctionOnOpeningModal(){
console.log(Id)
}
}
Child component HTML
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Ext {{Id}}</h4>
</div>
<div class="modal-body">
</div>
</div>
</div>
Parent Component TS
import { Component, OnInit } from '#angular/core';
#Component({
selector: 'ap-detail',
templateUrl: './p-details.component.html',
styleUrls: ['./p-details.component.css']
})
export class PDetailsComponent implements OnInit {
Id: string;
constructor(){
this.Id = "test";
}
}
When i open the modal it shows in the modal header but how to on call function on modal loads and passing the Id in that function.
Please don't down mark the question as i am in really big issue with this. Thanks in advance for the help.
You have to use the right selector to call your child component. So replace:
<!-- Modal content Starts-->
<app-f-ext [Id]="Id"></app-f-ext>
<!-- Modal content Ends-->
By:
<!-- Modal content Starts-->
<app-premium-extension [Id]="Id"></app-premium-extension>
<!-- Modal content Ends-->
And make sure to declare and initialize the Id var in your parent.component.ts file
You can then have access to the Id property in the ngOnInit function:
ngOnInit() {
console.log(Id);
}

I am trying assign unique id to my bootstrap modal as it's being using ngFor. Following is my code.
<div class="container shadow lead-container" data-toggle="modal" [attr.data-target]="customId"> -------------------------> . Data-target is set to customId
<div class="row text-left">
----------------------> Other Content goes here
</div>
</div>
<!--Lead Popup-->
<div class="modal fade" [attr.id]="customId" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true"> -----------> [attr.id] is set to customid
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="container popup-container">
<div class="row text-left">
-------------------------------------> Modal Content Goes Here
</div>
</div>
</div>
</div>
Following is my component.ts:
import { Lead } from './../models/lead';
import { Component, OnInit, Input } from '#angular/core';
#Component({
selector: 'app-lead',
templateUrl: './lead.component.html',
styleUrls: ['./lead.component.css']
})
export class LeadComponent implements OnInit {
#Input() public lead: Lead;
#Input() public index;
public customId: string;
constructor() {
}
ngOnInit() {
this.customId = "custom".concat(this.index);
}
}
When i click on div. The modal doesnt popup for some reason. Any help would be much appreciated
add "#" to the id.
[attr.data-target]="'#'+customId"
Similar questions have been asked before but I can't seem to apply their solution to this specific use case.
I'm trying to increase the width of my modal window, the most common solutions are to encase the content in a <div class="modal-dialog"></div> However, when I try this solution the modal becomes completely unresponsive, the formatting gets strange and the buttons stop working.
I used this ng-bootstrap guide for making the component and my desired end-result is a 90% width modal window in which I can place other components based on situation.
Here is the containing component code:
<p>You can pass an existing component as content of the modal window. In this case remember to add content component
as an <code>entryComponents</code> section of your <code>NgModule</code>.</p>
<button class="btn btn-lg btn-outline-primary" (click)="openModal()">Launch demo modal</button>
Here is the containing component.ts:
import { Component, OnInit } from '#angular/core';
import {NgbModal, NgbActiveModal} from '#ng-bootstrap/ng-bootstrap';
import {ModalInvoicePopupComponent} from '../modal-invoice-popup/modal-invoice-popup.component';
#Component({
selector: 'app-about-us',
templateUrl: './about-us.component.html',
styleUrls: ['./about-us.component.css']
})
export class AboutUsComponent implements OnInit {
constructor(private modalService: NgbModal) {}
openModal() {
const modalRef = this.modalService.open(ModalInvoicePopupComponent);
}
ngOnInit() {
}
}
Here is the modal-component html:
<div class="modal-header">
<h4 class="modal-title">myModal title</h4>
<button type="button" class="close" aria-label="Close" (click)="activeModal.dismiss('Cross click')">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<p>myModal body</p>
<p>Size differences when a large string is inserted, test of scaling</p>
<p>Importing an existing app into the modal, what happens then?</p>
<app-invoices></app-invoices>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-outline-dark" (click)="activeModal.close('Close click')">Close</button>
</div>
If I try to encase the modal-component inside a modal-dialog div it just breaks, and starts looking like this:
And becomes completely unresponsive.
Is there a good way to increase the size of a modal popup when used as a component in Angular?
Change your function like below :
openModal() {
const modalRef = this.modalService.open(ModalInvoicePopupComponent, {
width: '78vw'
});
}
It will give the width of modal 78vw and you can change it according to your mobile devices.
You have used NgbModal, in that case for defining the size of modal you can go for NgbModalOptions.
There you can define the size of the modal while opening it, say
this.modalService.open(content,{
size: 'xl'
});
refer https://ng-bootstrap.github.io/#/components/modal/api for detailed information.
I am trying to create a cancel function that cancels a specific viewing based on its id. I have a viewings model that I retrieve from firebase as an observable, I then input it into a child div. The problem being that when I click cancel, it always cancels the first viewing on the page, not the specific one that I click.
The strange thing is, that I created a new component on the same level as my modal component, Input the data in the exact same way, and that works perfectly. It only seems to be with the modal that It does not work.
<div class="col-md-3 buttons" [hidden]='!hidden' [#sliderDiv]="out">
<button class="button button-primary button-sm button-green text-center" (click)="updateViewingStatus()">Update Time</button>
<button data-toggle="modal" data-target="#cancelModal" class="button button-primary button-sm button-previous text-center">Cancel Viewing</button>
</div >
<viewings-cancel-modal [viewings]="viewings"></viewings-cancel-modal>
<testing-cancel [viewings]="viewings"></testing-cancel>
</div>
this is where I input viewings property into the child components. Both identical.
this is my test logic (using just a button) that works perfectly:
export class TestingCancelComponent implements OnInit {
#Input() viewings: TenantViewingModel;
private viewingsId;
constructor(private _viewings: ViewingsService) { }
ngOnInit() {
this.viewingsId = this.viewings.viewings_id;
console.log(this.viewings.viewings_id)
}
updateViewingStatus() {
this._viewings.updateViewingStatus(this.viewingsId);
}
}
And this is my modal logic (that doesnt work) :
export class PropertyViewingsCancelModalComponent implements OnInit {
#Input() viewings: TenantViewingModel;
private viewingsId;
constructor(private _viewings: ViewingsService) { }
ngOnInit() {
this.viewingsId = this.viewings.viewings_id;
// console.log(this.viewings.viewings_id)
}
updateViewingStatus() {
this._viewings.updateViewingStatus(this.viewingsId);
}
}
Which again are identical. The html for the working button is as follows:
<button (click)="updateViewingStatus()"></button>
and the non-working modal:
<div class="modal" id="cancelModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="text-center modal_title"> Are you sure you want to </div>
<h1 class="text-center" id="exampleModalLongTitle">Cancel Viewing? {{viewingsId}}</h1>
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
</button>
</div>
<div class="modal-body">
<div class="container">
<img src="/assets/img/site/cancel.svg" alt="" style="height: auto; width: 100%; padding: 25px">
<div class="row">
<div class="col-md-6">
<button data-dismiss="modal" class="button button-primary button-xs button-previous text-center" (click)="updateViewingStatus()">confirm</button>
</div>
<div class="col-md-6 text-right">
<button data-dismiss="modal" (click)="logViewings()" class="button button-primary button-xs button-blue text-center">back</button>
</div>
</div>
</div>
</div>
</div>
</div>
</div>
So just as a re-cap:
The button test works perfectly, removing the specific viewing that I want to remove or cancel. But with the modal, it only removes the first viewing on the page, even though the logic is identical, and I pass the data through to each child component in the exact same way.
Here some working example let's try this,
Html File,
<!--Pass your id as argument to your method.-->
<button (click)="onCancel(id)" class="button button-primary button-sm button-previous text-center">Cancel Viewing</button>
<!--This button has been hiden element is used to call your method -->
<button type="button" class="hideElement" data-toggle="modal" data-target="#cancelModal" #cancelModal></button>
<viewings-cancel-modal [viewings]="viewings"></viewings-cancel-modal>
Typescript File,
import { ElementRef, ViewChild } from '#angular/core';
#ViewChild('cancelModal') private cancelModal: ElementRef;
public onCancel(id:number) {
//set some global variable has been id value
localstorage.setItem("Id",id); //here set value as local storage.
this.viewings.viewings_id=id;
this.cancelModal.nativeElement.click(); //then here iam doing call that modal
}
Modal typescript File,
export class PropertyViewingsCancelModalComponent implements OnInit {
#Input() viewings: TenantViewingModel;
private viewingsId;
constructor(private _viewings: ViewingsService) { }
ngOnInit() {
//this.viewingsId = this.viewings.viewings_id;
this.viewingsId = localstorage.getItem("Id"); //here iam getting id value in localstorage
console.log("View Id",this.viewingsId) //here you getting your id you can proceed your process in modal button click time.
}
updateViewingStatus() {
this._viewings.updateViewingStatus(this.viewingsId);
}
}
It is a simple logic you have to implement your convenient. I hope it's helpful to solve your problem.
Thanks,

Hi, as seen above, creating modal with template will destro the template when, it is hidden. However; I don't want to be hidden. That is because, I use the modal for selecting some property multiple times from a list. Thus, every time, I have to load the modal. That causes a performance issue. Thus, Is there any way to stop it removing the modal from the dom.
I have a php page person.php that includes 2 vueJs components: person-details.vue and phones.vue. Each of these components include the same third component notify-delete. This notify-delete component includes a bootstrap modal dialog to confirm a deletion action of the parent component (person or phone).
I use props to set a message in the modal confirmation dialog and $refs to show it.
Problem:
When this props is set the msg props from the component person and the dialog is shown, the message is correctly set. However when I set from the phones component, the dialog shows the message set by person. as if person is constantly overriding the value of the msg props.
here is a sample of the code:
person.php:
<person-details details="<?= json_encode($person) ?>"></person-details>
<phones details="<?= json_encode($phones) ?>"></phones>
Person-details.vue:
<template>
<notify-delete ref="modalDeletePerson" :entity="'person'" :msg="deleteMsg" #confirmed="deleteMe"></notify-delete>
<button type="button" #click="confirmDelete">Delete this person</button>
</template>
<script>
export default {
data () {
return {
deleteMsg: ''
}
},
methods: {
confirmDelete() {
this.deleteMsg = 'Are you sure you want to delete this person?'
this.$refs.modalDeletePerson.show()
},
deleteMe() {
// delete person
}
}
}
</script>
</template>
Phones.vue:
<template>
<notify-delete ref="modalDeletePhone" :entity="'phone'" :msg="deleteMsg" #confirmed="deleteMe($event)"></notify-delete>
<button type="button" #click="confirmDelete">Delete this phone</button>
</template>
<script>
export default {
data () {
return {
deleteMsg: ''
}
},
methods: {
confirmDelete() {
this.deleteMsg = 'Are you sure you want to delete this phone?'
this.$refs.modalDeletePhone.show()
},
deleteMe() {
// delete phone
}
}
}
</script>
Notify-delete.vue:
<template>
<div id="modalDelete" class="modal fade" tabindex="-1" role="dialog">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-body">
{{msg}}
</div>
<div class="modal-footer">
<button type="submit" data-dismiss="modal" #click="confirm">Delete</button>
<button type="button" data-dismiss="modal">Cancel</button>
</div>
</div>
</div>
</div>
</template>
<script>
export default {
props: ['entity', 'msg'],
methods: {
show() {
$('#modalDelete').modal('show')
},
confirm() {
this.$emit('confirmed')
}
}
}
</script>
Any idea how I can have two distinguish instances of the same component?
The problem is here
show() {
$('#modalDelete').modal('show')
}
You are rendering two modals with the same id, then using jQuery to show them. Specifically, $('#modalDelete') will contain two elements. I expect the modal method just picks the first one and shows it.
Try
<div ref="modal" class="modal fade" tabindex="-1" role="dialog">
and
show() {
$(this.$refs.modal).modal('show')
}
This should give each instance of the Notify-delete.vue component it's own reference.
