Angular2 Bootstrap modal user inputs + image - html

I am using a bootstrap model to create and update groups. on the backend side, there are no issues. Below I have my ts and HTML code I used. the modal works fine, but I don't know how to return any values from my form to my ts file so i can use it in an API call.
also for an image I need formdata
in short:
What's the issue: Returning user inputs(+image) in angular 2
!edit! the error i get is:
_co.save is not a function
html:
<app-modal #modal>
<div class="app-modal-header">
header
</div>
<div class="app-modal-body">
<form #modalform="ngForm" (ngSubmit)="save(modalform.value)" >
First name: <input type="text" name="FirstName" ngModel><br>
Last name: <input type="text" name="LastName" ngModel><br>
image: <input type="file" name="image" ngModel><br>
</form>
</div>
<div class="app-modal-footer">
<button type="button" class="btn btn-default" (click)="modal.hide()">Close</button>
<button type="button" class="btn btn-primary" (click)="modal.hide()">Save changes</button>
</div>
</app-modal>
TS:
#Component({
selector: 'app-modal',
template: `
<div (click)="onContainerClicked($event)" class="modal fade" tabindex="-1" [ngClass]="{'in': visibleAnimate}"
[ngStyle]="{'display': visible ? 'block' : 'none', 'opacity': visibleAnimate ? 1 : 0}" style=" background: rgba(0,0,0,0.6);">
<div class="modal-dialog" style="padding-top: 25%;">
<div class="modal-content">
<div class="modal-header">
<ng-content select=".app-modal-header"></ng-content>
</div>
<div class="modal-body">
<ng-content select=".app-modal-body"></ng-content>
</div>
<div class="modal-footer">
<ng-content select=".app-modal-footer"></ng-content>
</div>
</div>
</div>
</div>
`
})
export class ModalComponent {
public visible = false;
public visibleAnimate = false;
public show(): void {
this.visible = true;
setTimeout(() => this.visibleAnimate = true, 100);
}
public save(): void{
}
public hide(): void {
this.visibleAnimate = false;
setTimeout(() => this.visible = false, 300);
}
public onContainerClicked(event: MouseEvent): void {
if ((<HTMLElement>event.target).classList.contains('modal')) {
this.hide();
}
}
}

fixed it by placing the save function in the other component

Cant post the data using Modal with Ajax in Razor Pages

This is the index file code:
public IList<Employee> Employee { get; set; }
public async Task OnGetAsync()
{
Employee = await _context.Employee.ToListAsync();
}
public JsonResult EmployeeList()
{
var data = _context.Employee.ToList();
return new JsonResult(data);
}
[HttpPost]
public JsonResult AddEmployee(Employee e)
{
var emp = new Employee()
{
Name = e.Name,
Age = e.Age,
Email = e.Email
};
_context.Employee.Add(emp);
_context.SaveChanges();
return new JsonResult("Success!!!");
}
Button to open Modal:
<button class="btn btn-info mb-3" id="btn1">Add Employee</button>
The Modal:
<!-- The Modal -->
<div class="modal Add-Emp">
<div class="modal-dialog">
<div class="modal-content">
<!-- Modal Header -->
<div class="modal-header">
<h4 class="modal-title">Add Employee</h4>
<button type="button" class="btn-close" data-bs-dismiss="modal"></button>
</div>
<!-- Modal body -->
<div class="modal-body">
<form method="post">
<div asp-validation-summary="ModelOnly" class="text-danger"></div>
<div class="form-group">
<label>Name</label>
<input type="text" placeholder="Enter Name" class="form-control" id="Name" autocomplete="off"/>
</div>
<div class="form-group">
<label>Age</label>
<input type="text" placeholder="Enter Age" class="form-control" id="Age" autocomplete="off"/>
</div>
<div class="form-group">
<label>Email</label>
<input type="text" placeholder="Enter Email" class="form-control" id="Email" autocomplete="off"/>
</div>
</form>
</div>
<!-- Modal footer -->
<div class="modal-footer">
<button class="btn btn-primary" onclick="AddEmployee();">Save</button> I
<button class="btn btn-danger btn-default" data-bs-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
The Js Code:
$("#btn1").click(function () {
$(".Add-Emp").modal("show")
})
function AddEmployee() { debugger
var objData = { Name: $("#Name").val(), Age: $("#Age").val(), Email: $("#Email").val() }
$.ajax({
url: "Pages/Employees/Index/AddEmployee",
type: "Post",
data: objData,
contentType: "application/xxx-www-form-url-encoded; charset=utf-8",
dataType: "json",
success: function () { alert("Data Saved"); },
error: function () { alert("Error!!!"); }
})
}
Modal opens on click But data does not get posted on clicking the save button it displays alert "Error!!!" defined in failure of ajax requestㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤㅤ
1.You maybe not familiar with Razor Pages, Razor pages uses OnGet and OnPost to deal with the Http Get and Post request. If you need another Get or Post method in current PageModel, you need define the method name like: OnGetHandlerName or OnPostHandlerName.
2.If your .cshtml.cs file located like: Pages/Employees/Index.cshtml.cs, the request url should be:/Employees/Index. If you set the handler in your PageModel, the request url should be:/Employees/Index?handler=xxx.
3.For how to use Ajax in Razor Pages, Razor Pages enable anti-forgery token validation by default, so you need add this token to header in ajax.
If you use form in Razor Pages, it will default generate an input with token. If not, you need add #Html.AntiForgeryToken() manually.
A whole working demo you could follow:
Page(Pages/Employees/Index.cshtml):
#page
#model IndexModel
<button class="btn btn-info mb-3" id="btn1">Add Employee</button>
<div class="modal Add-Emp">
<div class="modal-dialog">

Signaturepad clear property not clearing in modal-bootstrap dialog box

I am working on signature pad dialogue box and for the dialogue box i am using bootstrap modal. In this activity when i click on complete activity a dialogbox should open asking yes or no on clicking yes a dialog box with signaturepad in modal body and clear button in modal footer.
the problem is when clicking on clear button from modal footer the clear method of signaturepad module is not working Any suggestions would be of great help
import { Component, OnInit, ViewChild, Directive } from '#angular/core';

</div>
<button type="button" class="btn btn-primary" (click)="onClear()">clear</button>
</ng-template>
<button class="btn btn-secondary" (click)="openSm(content)">Complete Activity</button>
The reason this happens is because ng-template is not rendered yet and thus the signature pad will be undefined. A way I found to work around this is to create my signature pad in a separate component and then add that component to the ngbModal.
So in your example:
<ng-template #longContent let-modal>
<div class="modal-header">
<button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="col-md-12">
<div class="m-signature-pad">
<div class="m-signature-pad-body">
<!-- <signature-pad #SignaturePad1 [options]="signaturepadoption"></signature-pad> -->
<app-my-signature-pad-component></app-my-signature-pad-component> <!-- In this component you add the above commented out line and then do your functionality for the signature pad there. -->
</div>
</div>
</div>
</div>
<button type="button" class="btn btn-primary" (click)="onClear()">clear</button>
</ng-template>
I found that with this approach, you are able to use the ViewChild and don't get the undefined issue.
Hope this makes sense!

How to hide bootstrap modal form after submitting values, using Angular2 in vs2017

I want to know, how to hide below shown Bootstrap modal form, after submitting the value to the service. I have tried with commented code, but didn't help me. Is there any alternatives.?
settings.component.ts
import { Component, OnInit} from '#angular/core';
import { CategoryVM } from '../view-models/category';
import { AppDataService } from '../services/app-data.service';
import { NgForm } from '#angular/forms';
import { FormControl, FormGroup, Validators } from '#angular/forms';
import { Location } from '#angular/common';
//declare var $: any;
#Component({
selector: 'app-settings',
templateUrl: './settings.component.html',
styleUrls: ['./settings.component.css']
})
export class SettingsComponent implements OnInit {
categories: CategoryVM[] = [];
form: FormGroup;
errorMessage: string;
//visible: boolean;
//private visibleAnimate = false;
// public visible = true;
constructor(private dataService: AppDataService, private location: Location) {
dataService.getCountries().subscribe((data) => this.categories = data);
}
ngOnInit() {
this.dataService.vm = { ParentId: 0, Name: "" };
// this.visible = true;
}
onBack() {
this.errorMessage = null;
this.location.back();
}
onCancel() {
this.onBack();
}
onSubmit(form: NgForm) {
this.dataService.createCategory(form.value)
.subscribe(data => {
alert("Value Added Successfully");
//$("#myModal").hide();
//$("#myModal").modal("hide");
// this.visible = false;
this.categories.push(data);
//document.getElementById("openModalButton").click();
});
}
}
Please focus in OnSubmit() event of form in above and Below is the template
settings.component.html
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">start here</button>
<!--<button id="openModalButton" [hidden]="true" type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">start here</button>-->
<div id="myModal" class="modal fade" role="dialog">
<!--<div id="myModal" class="modal fade" role="dialog" *ngIf="visible">-->
<div class="modal-dialog">
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Login</h4>
</div>
<div class="modal-body">
<form class="cat-form" #categoryForm="ngForm" (ngSubmit)="onSubmit(categoryForm)">
<!--<form class="cat-form" #categoryForm="ngForm" (ngSubmit)="onSubmit(categoryForm);visible=false;">-->
<label>Name</label>
<div class="form-group">
<input class="form-control" name="Name" placeholder="Name" #Name="ngModel" [(ngModel)]="dataService.vm.Name">
</div>
<div class="form-row">
<div class="form-group col-md-8">
<button type="submit" class="btn btn-lg btn-block btn-primary">Create</button>
</div>
<div class="form-group col-md-4">
<button type="button" class="btn btn-lg btn-block" (click)="onCancel()" data-dismiss="modal">Cancel</button>
</div>
</div>
</form>
</div>
</div>
</div>
</div>
If I use commented line of code Modal-form will hide, but opacity remains as shown in this image
Your commented code is a jQuery code, so I assume you don't use an Angular Framework (like ng-bootstrap for example).
You should have a look and integrate one of the abstraction of Bootstrap.
Use jQuery in your component means you manipulate directly the dom and this is really not the good way to do.

OnChange Typescript input

I want to be able to trigger an on change when a file is selected from a input(file). I want the triggered event to set a textbox to be the name of the file.
I am using HTML5, Typescript and Angular2. I can't figure out or find an example of exactly how to produce the behavior I am after.
see my code below:
component.ts
import { Component } from '#angular/core';
import { Http } from '#angular/http';
import { Headers, RequestOptions } from '#angular/http';
#Component({
selector: 'testConnection',
// ignore error on require
template: require('./testConnection.component.html')
})
export class TestConnectionComponent {
public http: Http;
public requestData: RequestData;
public constructor(http: Http) {
this.http = http;
(<HTMLInputElement>document.getElementById('fileInput')).onchange = (ev: Event) => {
var fileInput = (<HTMLInputElement>ev.srcElement).files[0];
var fileTextbox = (<HTMLInputElement>document.getElementById('fileTextbox'));
fileTextbox.value = fileInput.name;
}
}
public testButtonClick() {
// Iniatialise Request object
let request: RequestData;
request = { "CountryCode": "", "SiteIDList": "" };
// Get site(s)
var siteIdList = (<HTMLInputElement>document.getElementById('siteIDInput')).value;
// Get selected country
var countryCode = (<HTMLInputElement>document.getElementById('countryDropdown')).value;
// Veryify contents is just site ids.
// TODO
request.CountryCode = countryCode;
request.SiteIDList = siteIdList;
// Set Http POST options
let headers = new Headers({ 'Content-Type': 'application/json' });
let options = new RequestOptions({ headers: headers });
// Call Api with test connection data
this.http
.post('/api/TestConnection/TestConnection', JSON.stringify(request), options)
.subscribe(data => {
// alert request ok
alert('ok');
}, error => {
// Log error
console.log(error.json());
});
}
}
interface RequestData {
SiteIDList: string;
CountryCode: string;
}

Try using (change) event binding
<input type="file" id="fileInput" style="display:none;" (change)="setFileName()"/>
If you need to retrieve the file name before uploading it you can do it this way :
#Component({
selector: 'my-app',
template: `
<div>
<input type="file" (change)="onChange($event)"/>
</div>
<p>Filename : {{filename}}</p>
`,
providers: []
})
export class AppComponent {
filename: string;
constructor() { }
onChange(event) {
this.filename = event.srcElement.files[0].name;
}
}
Here is a working plunker

Populate input using #Input inside Bootstrap 4 modal

I have a main page with a table that when a row is clicked on, it uses #Output to send out that row's data (I've already confirmed the data is being sent properly by using it in another place in the project). I then have a Bootstrap 4 modal that pops up when I click the button on the left below where it says "Data Point Information". What I need to do is take the data from the row that was clicked on, and populate the form inside the modal with it.
Main Page:

}
HTML from the main page that places modal there using it's selector (toSend is of type DataTable which is the data from the row I am sending from the main page's Typescript):
<update-validation [receivedRow]='toSend'></update-validation>
Since I'm using #Output and #Input, I'm not sure why receivedRow in my Typescript is undefined.
The reason is that when your component of modal initialized, there were not any receivedRow. You should control it with *ngIf directive and ngOnChange method like that;
//xyz is just any field on your parent component
//in html
<div *ngIf="xyz">
<update-validation [receivedRow]="xyz"></update-validation>
</div>
//in component of modal
ngOnChanges(){
if(receivedRow){
//do whatever you want
}
}
