Overview

Sets the readonly attribute on the element, if the expression inside ngReadonly is truthy. Note that readonly applies only to input elements with specific types. See the input docs on MDN for more information.

A special directive is necessary because we cannot use interpolation inside the readonly attribute. See the interpolation guide for more info.

Directive Info

</INPUT>
