Widget Web Component

To facilitate a deeper integration with your website, we provide a the widget as a web component. This allows you to customize the widget experience even further.

To get start, include the widget library:

<script src="https://widget.booker25.com/js/widget25.js"></script>

Then use either the full-fledged button (like the generated script), or the bare widget (comparable to the iframe):

<!-- This displays a button at the bottom of your page -->
<booker-button page="uuid-of-your-page" business="your-business-slug"></booker-button>
<!-- This behaves much like the iframe -->
<booker-widget page="uuid-of-your-page" business="your-business-slug"></booker-widget>

AttributeTokenList

This object mimics the behaviour of DOMTokenList, as we cannot instantiate that directly. This object is a view of the attribute of an element and thus does not have any state of its own. When adding or removing tokens, extra whitespace can be stripped and duplicates can be removed.

Name	Type	Description

Name	Type	Description
add(…tokens: string[])	method	Accepts any number of parameters. Each parameter is treated as a String token to be added to the attribute.
remove(…tokens: string[])	method	Accepts any number of parameters. Each parameter is treated as a String token to be removed from the attribute.
contains(token: string): boolean	method	Returns whether or not token is part of the token list.
toggle(token: string): boolean toggle(token: string, force: boolean): boolean	method	Add or removes the token to the list, depending on the current state or the force parameter. Returns whether the token is in the list after the call.
length: number	property	The amount of tokens in the list.
