/**
|
|
* The `Button` component defines an element which, when clicked, performs an
|
|
* action. The button may have the following special props:
|
|
*
|
|
* - `icon` The name of the icon class. If specified, the button will be given a
|
|
* 'has-icon' class name.
|
|
* - `disabled` Whether or not the button is disabled. If truthy, the button
|
|
* will be given a 'disabled' class name, and any `onclick` handler will be
|
|
* removed.
|
|
* - `loading` Whether or not the button should be in a disabled loading state.
|
|
*
|
|
* All other props will be assigned as attributes on the button element.
|
|
*
|
|
* Note that a Button has no default class names. This is because a Button can
|
|
* be used to represent any generic clickable control, like a menu item.
