Input validation with pattern Angular 2

Question

I\'m currently writing a simple form in ionic 2 (Angular 2). I was wondering how I\'d add a simple regular expression pattern to the validation:

I basically have this:

Answer 1

Add the pattern to a variable

var pattern=/06([0-9]{8})/;

and bind the attribute to it

Seems this PR https://github.com/angular/angular/pull/6623/files needs to land first.

There is still an open issue https://github.com/angular/angular/issues/7595 This prevents pattern being bound to. The pattern needs to be statically added to the DOM (without binding) to work.
