I need to submit a form coming from a payment gateway. Our backend guy asks me to either put the innerHtml and send after it rendered. I got it to work on Chrome, but failed on Firefox.
Now I'm trying to fix it on our testing environment, the backend added a JSON return of all the properties I need to replicate the form he was sending me so I can make my own form. But still failing to submit on Firefox.
Does someone have the same experience? Please shed me some light.
Is there any Firefox specific fixes I need to know?
Below is the working code on Chrome and Safari
import { Component, OnInit, AfterViewInit, ViewChild, ElementRef,DoCheck, ViewChildren, QueryList } from '#angular/core';
import { BrowserModule, DomSanitizer, SafeResourceUrl, SafeUrl} from '#angular/platform-browser';
import { PaymentService } from '../../_services/payment.service';
import { Loader } from '../../_services/loader.service';
#Component({
selector: 'bdf-payment-form',
templateUrl: './payment-form.component.html',
styleUrls: ['./payment-form.component.scss']
})
export class PaymentFormComponent implements OnInit,DoCheck, AfterViewInit {
form : SafeResourceUrl;
// #ViewChild('paymentFormContainer') container: ElementRef;
#ViewChild('paymentForm') myForm: ElementRef;
loader;
constructor(private paymentService:PaymentService,
private sanitizer: DomSanitizer,
private loaderService: Loader,
private elRef:ElementRef) { }
ngDoCheck(){
}
ngOnInit() {
console.log(this.paymentService.paymentForm);
this.paymentService.paymentForm ? this.form = this.sanitizer.bypassSecurityTrustHtml(this.paymentService.paymentForm) : null
this.loader = true;
}
ngAfterViewInit() {
let test;
if(this.form){
test = this.elRef.nativeElement.querySelector('form')
console.log(test)
test.submit();
}
}
}
You shouldn't use submit() method to avoid redirection with page refresh.
The http service is used to submit the form data serialized to json from the form. If you have form elements bound to the model then it would be easier to send the model back to the backend.

I'm learning Angular 9 and have gone through the Tour of Heroes app and tutorial. I've used this tutorial as a base to add new features such as CRUD operations on a remote resource and I have added #ng-bootstrap/ng-bootstrap to the projects but I cannot get angular-bootstrap-toggle to work.
The instructions on Bootstrap Toggle don't match what I have learned so far and I can't find a solution anywhere.
For example, I don't know how this command angular.module('myApp', ['ui.toggle']); fits in with Angular 9 and the tutorial I have used.
How can I get the system to call onChange() when I click the toggle?
angular.json
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.min.css",
"node_modules/bootstrap4-toggle/css/bootstrap4-toggle.min.css",
"src/styles.css"
],
"scripts": [
"node_modules/jquery/dist/jquery.min.js",
"node_modules/bootstrap/dist/js/bootstrap.bundle.js",
"node_modules/bootstrap4-toggle/js/bootstrap4-toggle.min.js"
]
navigation-bar.component.html This displays correctly and toggles as expected
<input id="local-browse" (change)="onChange()" type="checkbox" checked="" data-toggle="toggle" data-on="Local" data-off="Remote" data-onstyle="success" data-offstyle="danger" data-size="sm">
navigation-bar.component.ts If I put in a standard checkbox the onChange() does work as expected but not with angular-bootstrap-toggle
import { Component, OnInit } from '#angular/core';
declare var $: any;
#Component({
selector: 'app-navigation-bar',
templateUrl: './navigation-bar.component.html',
styleUrls: ['./navigation-bar.component.css'],
})
export class NavigationBarComponent implements OnInit {
localUrl = 'http://192.168.253.53';
remoteUrl = 'https://remoteaddress.com';
local = true;
constructor() {}
ngOnInit(): void {
$(document).ready(() => {
console.log('The document ready for jQuery!');
});
}
onChange() {
if (this.local === true) {
this.local = false;
} else {
this.local = true;
}
}
}
I dont think it is compatible with Angular 2+ (or at least angular 9).
You may like to use ng-toggle from https://www.npmjs.com/package/#nth-cloud/ng-toggle
Which is tested on Angular 9.

I wanted to know how I can hide a header in Ionic 4 by scrolling down the page, and re-show it when scrolling up.
I found many solutions on how to do that, but they all turned out to not working or being out-of-date.
So I collected all piece of information I could find to provide this answer.
Thanks to this video I got it to work.
First of all call ionic g directive directives/hide-header. You can of course replace directive/hide-header with your own path and name.
hide-header.directive.ts
import { Directive, HostListener, Input, OnInit, Renderer2 } from '#angular/core';
import { DomController } from '#ionic/angular';
#Directive({
selector: '[appHideHeader]'
})
export class HideHeaderDirective implements OnInit {
#Input('header') header: any;
private lastY = 0;
constructor(
private renderer: Renderer2,
private domCtrl: DomController
) { }
ngOnInit(): void {
this.header = this.header.el;
this.domCtrl.write(() => {
this.renderer.setStyle(this.header, 'transition', 'margin-top 700ms');
});
}
#HostListener('ionScroll', ['$event']) onContentScroll($event: any) {
if ($event.detail.scrollTop > this.lastY) {
this.domCtrl.write(() => {
this.renderer.setStyle(this.header, 'margin-top', `-${ this.header.clientHeight }px`);
});
} else {
this.domCtrl.write(() => {
this.renderer.setStyle(this.header, 'margin-top', '0');
});
}
this.lastY = $event.detail.scrollTop;
}
}
After that, in your template:
<ion-header #header>
<ion-toolbar><ion-title>Test</ion-title></ion-toolbar>
</ion-header>
<ion-content scrollEvents="true" appHideHeader [header]="header">
</ion-content>
Take care of the scrollEvents, appHideHeader and the [header] attributes! The last one takes the header element as argument, in this case #header.
Most of the code is the same as shown in the video. I changed the host-property from the #Directive and used the more up-to-date HostListener.
If you want to use the directive in more than one directive, you need to create a SharedModule.
To do so, create the module with ng g module shared. After that, add the HideHeaderDirective to the declarations and the exports array.
shared.module.ts
import { NgModule } from '#angular/core';
import { CommonModule } from '#angular/common';
import { HideHeaderDirective } from './directives/hide-header.directive';
#NgModule({
declarations: [HideHeaderDirective],
exports: [HideHeaderDirective],
imports: [
CommonModule
]
})
export class SharedModule {}
Now add the shared module to all the modules you want to use the directive in.
Note: You cannot import the directive in app.module.ts and use it in a submodule! You have to import the shared module in every direct module you want to use the directive in.
My current versions of node, npm and ionic:
For this you can just place the ion-header before the ion-content. this is the simple answer for that.
I have two ngx-bootstrap modals created as a standalone components (not with template variables) - Login modal and Register modal. Each of the modals are have separate components which are located in my shared module and can be called from other modules. But the thing is that there is an option these modals to call each other - you can click a button from the login modal which has to bring you the Register modal and vice versa. When I try doing this using the BsModalService I get circular dependency errors since I have imported the login component in the register component and the register component in the login component.
I've tried to put this modal switching logic in a service with the hope that I won't get a circular dependency but it didn't help.
import { Component, OnInit } from '#angular/core';
import { FormGroup, FormBuilder, Validators } from '#angular/forms';
import { BsModalRef, BsModalService } from 'ngx-bootstrap/modal';
import { UserService } from 'src/app/core/services';
import { User } from 'src/app/core';
import { RegisterModalComponent } from '../register-modal/register-modal.component';
#Component({
selector: 'app-login-modal',
templateUrl: './login-modal.component.html',
styleUrls: ['./login-modal.component.css']
})
export class LoginModalComponent implements OnInit {
loginForm: FormGroup = this.fb.group({
// form definition
});
constructor(
public loginModalRef: BsModalRef,
private fb: FormBuilder,
private router: Router,
private user: UserService,
private modalService: BsModalService
) { }
ngOnInit() {
}
onSubmit() {
// form submit code ...
// hide the current modal
this.loginModalRef.hide();
}
openRegisterModal() {
// hide the current modal
this.loginModalRef.hide();
// open the new modal
this.modalService.show(RegisterModalComponent, {
animated: true,
class: 'modal-lg'
});
}
}
I have included only the code from the login modal since the situation on the other side is similar.
Just to mention that as a temporary solution I just made one modal component to serve the purpose as modal and I refactored the login and the register components to be like a regular components so I can include them inside the modal and switch them with ngIf depending on the parameters that I'm calling the modal with.
There is some components in Ionic that do not provide an event that is emitted when focus is lost.
For example ion-input provides ionBlur. On the other hand there is other elements like ion-content where I need to detect an outside click, but without knowing which event to use.
Is there a way to achieve that without being limited to the proposed events in the documentation?
I found this article that shows a way to use a custom directive to detect an outside click:
import {Directive, ElementRef, Output, EventEmitter, HostListener} from '#angular/core';
#Directive({
selector: '[clickOutside]'
})
export class ClickOutsideDirective {
constructor(private _elementRef : ElementRef) {
}
#Output()
public clickOutside = new EventEmitter();
#HostListener('document:click', ['$event.target'])
public onClick(targetElement) {
const clickedInside = this._elementRef.nativeElement.contains(targetElement);
if (!clickedInside) {
this.clickOutside.emit(null);
}
}
}
The directive can then be used this way, after declaring it in the concerned module:
<!-- HTML Template -->
<ion-content (clickOutside)="handleOutsideClick()"><!-- ... --></ion-content>
<!-- Typescript code -->
handleOutsideClick() {
//Handle My outside Click
}
Yeah, It's been 7 months since asked.
Stucked with the same issue; this solved the issue
TS
#ViewChild('content') content: ElementRef
#HostListener('document:click', ['$event'])
andClickEvent(event) {
if (!this.content.nativeElement.contains(event.target)) {
if (!this.navCtrl.isTransitioning() && this.navCtrl.getActive()) {
this.close()
}
}
}
HTML
<ion-content #content>
What is the method for redirecting the user to a completely external URL in Angular 2. For example, if I need to redirect the user to an OAuth2 server in order to authenticate, how would I do that?
Location.go(), Router.navigate(), and Router.navigateByUrl() are fine for sending the user to another section (route) within the Angular 2 app, but I can't see how they could be used to redirect to an external site?
You can use this-> window.location.href = '...';
This would change the page to whatever you want..
An Angular approach to the methods previously described is to import DOCUMENT from #angular/common (or #angular/platform-browser in Angular
< 4) and use
document.location.href = 'https://stackoverflow.com';
inside a function.
some-page.component.ts
import { DOCUMENT } from '#angular/common';
...
constructor(#Inject(DOCUMENT) private document: Document) { }
goToUrl(): void {
this.document.location.href = 'https://stackoverflow.com';
}
some-page.component.html
<button type="button" (click)="goToUrl()">Click me!</button>
Check out the platformBrowser repo for more info.
The solution, as Dennis Smolek said, is dead simple. Set window.location.href to the URL you want to switch to and it just works.
For example, if you had this method in your component's class file (controller):
goCNN() {
window.location.href='http://www.cnn.com/';
}
Then you could call it quite simply with the appropriate (click) call on a button (or whatever) in your template:
<button (click)="goCNN()">Go to CNN</button>
I think you need à target="_blank", so then you can use window.open :
gotoGoogle() : void {
window.open("https://www.google.com", "_blank");
}
If you've been using the OnDestry lifecycle hook, you might be interested in using something like this before calling window.location.href=...
this.router.ngOnDestroy();
window.location.href = 'http://www.cnn.com/';
that will trigger the OnDestry callback in your component that you might like.
Ohh, and also:
import { Router } from '#angular/router';
is where you find the router.
---EDIT---
Sadly, I might have been wrong in the example above. At least it's not working as exepected in my production code right now - so, until I have time to investigate further, I solve it like this (since my app really need the hook when possible)
this.router.navigate(["/"]).then(result=>{window.location.href = 'http://www.cnn.com/';});
Basically routing to any (dummy) route to force the hook, and then navigate as requested.
in newer versions of Angular with window as an any
(window as any).open(someUrl, "_blank");
There are 2 options:
if you want to redirect in same window/tab
gotoExternalDomain(){
window.location.href='http://google.com/'
}
if you want to redirect in new tab
gotoExternalDomain(){
(window as any).open("http://google.com/", "_blank");
}
After ripping my head off, the solution is just to add http:// to href.
Go somewhere
I used window.location.href='http://external-url';
For me the the redirects worked in Chrome, but didn't work in Firefox.
The following code resolved my problem:
window.location.assign('http://external-url');
I did it using Angular 2 Location since I didn't want to manipulate the global window object myself.
https://angular.io/docs/ts/latest/api/common/index/Location-class.html#!#prepareExternalUrl-anchor
It can be done like this:
import {Component} from '#angular/core';
import {Location} from '#angular/common';
#Component({selector: 'app-component'})
class AppCmp {
constructor(location: Location) {
location.go('/foo');
}
}
You can redirect with multiple ways:
like
window.location.href = 'redirect_url';
another way Angular document:
import document from angular and the document must be inject as well as bellow otherwise you will get error
import { DOCUMENT } from '#angular/common';
export class AppComponent {
constructor(
#Inject(DOCUMENT) private document: Document
) {}
this.document.location.href = 'redirect_url';
}
None of the above solutions worked for me, I just added
window.location.href = "www.google.com"
event.preventDefault();
This worked for me.
Or try using
window.location.replace("www.google.com");
To use #Inject, you must import it. I didn't see this in any of the answers.
TS file:
import { Component, Inject } from '#angular/core';
import { DOCUMENT } from '#angular/common';
#Component({
selector: 'app-my-comp.page',
templateUrl: './my-comp.page.component.html',
styleUrls: ['./my-comp.page.component.scss']
})
export class MyCompPageComponent {
constructor(
#Inject(DOCUMENT) private document: Document
) { }
goToUrl(): void {
this.document.location.href = 'https://google.com/';
}
}
HTML file:
<button type="button" (click)="goToUrl()">Google</button>
In your component.ts
import { Component } from '#angular/core';
#Component({
...
})
export class AppComponent {
...
goToSpecificUrl(url): void {
window.location.href=url;
}
gotoGoogle() : void {
window.location.href='https://www.google.com';
}
}
In your component.html
<button type="button" (click)="goToSpecificUrl('http://stackoverflow.com/')">Open URL</button>
<button type="button" (click)="gotoGoogle()">Open Google</button>
<li *ngFor="item of itemList" (click)="goToSpecificUrl(item.link)"> // (click) don't enable pointer when we hover so we should enable it by using css like: **cursor: pointer;**
Just simple as this
window.location.href='http://www.google.com/';
