Introduction

CheckedMixin is a mixin that provides basic properties for elements on the page that can be checked.

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 isChecked = $w("#CheckedMixin").checked;

Instead, you can code the following, because checkboxes are elements that "mix in" CheckedMixin.

let isChecked = $w("#myCheckbox").checked;
