AngularJS Numbers and Return

Question

is there a way to use AngularJS to only accept Numbers and Return (/n/r) in a textarea? similarly like this:

<textarea>
2344
5335
55555
2222
234
</textarea>

Above is just an example of what I am trying to restrict the text area to. Any suggestions would be great. Thanks!

Theoretically you can use ngPattern like this:

ngPattern="/[0-9\r\n]*/"

With this setting the textarea will enable anything to type, but treats only numbers and returns as valid.

Probably you can use for example ngChange, to filter out anything non-valid.

angularJS does not add a class to the textarea when the pattern is invalid.
