Introduction

ReadOnlyMixin is a mixin that provides basic properties for elements on the page that support readonly mode.

About Mixins

Mixins provide functionality that other elements can inherit and use.

Mixins are not elements. You cannot add mixins to a page in the Editor like other $w elements, and mixins are not meant to be used directly in your code.

For example, you would not write code like this, because it is out of context:

let isReadonly = $w("#ReadOnlyMixin").readOnly;

Instead, you can code the following if myElement is an element that "mixes in" ReadOnlyMixin.

let isReadonly = $w("#myElement").readOnly;
