_this.testFormEl.nativeElement.submit is not a function for Form Post - post

Question

I have a hidden form in a dialog which I want to submit automatically.
HTML Code :
<form #formVal method="POST" [action]="urlvalue">
<p *ngFor="let item of redirectData.RedirectData.Form.Parameter;
let pindex = index;">
<input type="hidden" [name]="item.name" [value]="item.value">
</p>
</ form>
`
In my previous angular 1.5 code I was doing
$timeout(() => {
angular.element('#3DSForm').submit();
}, 100);
and it was working but here in Angular 6 I tried using ViewChild in ngAfteronInit but still no luck I am getting error for native element, I even used ngNoform in my HTML but didn't work out.
#ViewChild('formVal') form: ElementRef;
setTimeout(() => {
this.form.nativeElement.submit();
}, 200);
Kindly suggest what am I missing

Answer 1

You probably have some element called submit.
Example:
<input type="hidden" name="submit">
Rename it to something else, e.g btnSubmit.

Answer 2

You should call click event for submit button like this,
<form #formVal method="POST" [action]="urlvalue">
<div *ngFor="let item of redirectData.RedirectData.Form.Parameter; let pindex = index;">
<input type="hidden" [name]="item.name" [value]="item.value">
</div>
<input type="hidden" name="submit" #submitBtn>
</ form>
in ts file
#ViewChild('submitBtn') submitBtn: ElementRef;
submitForm() {
this.submitBtn.nativeElement.click();
}
after that call the submitForm() function from where you want to submit the function.

Answer 3

I was able to achieve it using HTMLFormElement.
<form ngNoForm name="myForm" id="myForm" [action]="urlvalue" method="POST">
<button type="submit" class="test" style="visibility: hidden;"></button>
</form>
This code in the component.
const form: HTMLFormElement = document.getElementById('myForm');
form.submit();
