Hello to all, welcome to therichpost.com. In this post, I will tell you, Angular 10 Bootstrap modal popup registration and login forms with validations.
Post Working:
Hi friends, after watching the above video, on what topic this video will based upon so that is why I make the videos for better understating of working.
Friends Angular 10 came and if you are new then please check below two links:
Here is the proper code snippet for Angular 10 Bootstrap modal popup registration and login forms with validations:
1. Very first, you need to run below commands to get angular 10 fresh setup and also you have latest nodejs version on your machine:
npm install -g @angular/cli //Setup Angular10 atmosphere ng new angularloginregisterforms //Install New Angular App /**You need to update your Nodejs also for this verison**/ cd angularloginregisterforms //Go inside the Angular 10 Project
2. Now run below commands to install bootstrap and jquery modules for modal pop working:
npm install jquery --save npm install bootstrap --save
3. Now add below code inside your angular.json file to get the bootstrap and jquery styles and scripts:
"styles": [ ... "node_modules/bootstrap/dist/css/bootstrap.min.css", ], "scripts": [ ... "node_modules/jquery/dist/jquery.min.js", "node_modules/bootstrap/dist/js/bootstrap.min.js", ]
4. Now add below code inside your src/app/app.module.ts file to declaration of modules:
...
import { ReactiveFormsModule } from '@angular/forms';
...
imports: [
...
ReactiveFormsModule
],
5. Now very important, add below code carefully inside your src/app/app.component.ts file for login register forms working and actions:
...
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
declare var $: any;
...
export class AppComponent {
...
//Declare forms variable for actions
registerForm: FormGroup;
submitted = false;
loginForm: FormGroup;
loginsubmitted = false;
//Register form actions
get f() { return this.registerForm.controls; }
onSubmit() {
this.submitted = true;
// stop here if form is invalid
if (this.registerForm.invalid) {
return;
}
//True if all the fields are filled
if(this.submitted)
{
$("#registermodal").modal("hide");
}
}
// Login form actions
get ff() { return this.loginForm.controls; }
onLoginSubmit() {
this.loginsubmitted = true;
// stop here if form is invalid
if (this.loginForm.invalid) {
return;
}
//True if all the fields are filled
if(this.loginsubmitted)
{
$("#loginmodal").modal("hide");
}
}
ngOnInit(){
//Login form validations
this.loginForm = this.formBuilder.group({
email: ['', [Validators.required, Validators.email]],
password: ['', [Validators.required]]
});
//Register form validations
this.registerForm = this.formBuilder.group({
email: ['', [Validators.required, Validators.email]],
password: ['', [Validators.required, Validators.minLength(6)]],
firstname: ['', [Validators.required]],
mobile: ['', [Validators.required, Validators.pattern(/^-?(0|[1-9]\d*)?$/), Validators.minLength(10)]]
});
}
}
6. Here is the code you need to add inside your src/app/app.component.html file and this will show the proper output on browser:
<div class="container">
<!--Login Register Forms Buttons-->
<button type="button" class="btn btn-primary mr-5" data-toggle="modal" data-target="#registermodal">Register</button>

Thanks

Property ‘formBuilder’ does not exist on type ‘AppComponent’.
50 this.loginForm = this.formBuilder.group({
Did you import formBuilder?
Yes, I did. Still it is showing the same error.
I declared that property and assigned type as any. And now, the modal wont appear on screen.
