Definition and Usage
The ng-maxlength
directive adds a restriction to an input field,
and to the validator of the form.
The ng-maxlength
is not the same as the maxlength
attribute in HTML, which will prevent users from typing more than the restricted
number of characters.
The ng-maxlength
directive will not prevent users from typing
more than the restricted number off characters, but the form will be invalid if
they do so.
