How To Stop The User Editing The Country Code In A Html Page Using Ngx-international-phone-number In Angular 6

Can we stop the user editing the country code in ngx-international-phone-number using angular 6 imported ngx-international-phone-number in appmodule.ts

Solution 1:

you can make this non editable. I have taken the example of Singapore country code. I have used keydown event. and I am checking the last position of country code.so if I have country code +65 then I am considering selectionStart greater than equal to 3.

My Html Code

<formname="sample-form" (ngSubmit)="submit(f)" #f="ngForm"><international-phone-numberngModel (keydown)="testInput($event)"name="phone_number"placeholder="Enter phone number" [maxlength]="20" [defaultCountry]="'sg'" [required]="true" #phoneNumber="ngModel"name="phone_number" [allowedCountries]="['sg']"></international-phone-number><div *ngIf="f.submitted && !phoneNumber.valid"class="help-block">Phone number is required and should be valid</div><buttontype="submit">Submit</button></form>

and my .ts file code is as below.

    testInput(event) 
{
  if (!(event.target.selectionStart >= 3) || (event.target.selectionStart < 4 && event.key === 'Backspace')) 
  {
    event.stopPropagation();
    event.preventDefault();
  }
}

code to get the value on form submit.

submit(f: NgForm) {
  console.log(f.value);
} 

Solution 2:

Best and simplest way you can stop a user editing an input is by adding the disabled attribute to the input.

For example <input type="text" name="countrycode" disabled>>

Let me know if that helps!
