Overlay

Description

It represents an overlay module. This module is responsible to create an overlay without predefining any inner overlay template.

It should be used by other modules to display their content in an overlay.

JIRA

Usage

The overlay component will be initialized without any markup reference. Next to that, it’s only purpose is to open and close itself and display provided content.

How do you work with the overlay?

It is really simple by using the publish/subscribe pattern. The overlay listens to:

EVENTS.overlay.open
EVENTS.overlay.close.

That means you only need to trigger the event and provide the content as a parameter.

Example

Let’s display an image in our overlay component. As long as all requirements are fulfilled you can execute the following:

Veams.Vent.publish(Veams.EVENTS.overlay.open, { content: '<img src="https://placehold.co/400x200" />' });

That’s it.

`overlay-usage.hbs`

Here you will find an onclick event which is just inlined to open the overlay. It is an easy way to show you a working example.

But we suggest to use @veams/component-cta for triggering global events out of the markup.

Requirements

@veams/core - Veams Core Framework.
@veams/query or jquery - Veams Query or jQuery.
@veams/component - Veams Component.

Installation

Installation with Veams

veams install component overlay

veams -i c overlay

JavaScript Options

The module gives you the possibility to override default options:

Option	Type	Default	Description
classes.open	String	`'is-open'`	Define the open class to open the overlay.
classes.noScroll	String	`'isnt-scrollable'`	Define the class that prevents scrolling of the page in the background.
selectors.closeBtn	String	`'[data-js-item="overlay-close"]'`	Define the element for close button.
selectors.figureImage	String	`'[data-js-item="figure-image"]'`	Define the element for figure image.
selectors.footer	String	`'[data-js-item="footer"]'`	Define the element for footer.
selectors.header	String	`'[data-js-item="header"]'`	Define the element for header.
selectors.main	String	`'[data-js-item="main"]'`	Define the element for main.
selectors.overlay	String	`'[data-js-item="overlay"]'`	Define the element for overlay.
selectors.regionContent	String	`'[data-js-item="overlay-content"]'`	Define the element for region content.
selectors.skipLinks	String	`'[data-js-item="skip-links"]'`	Define the element for skip links.
templates.default	String	`'OVERLAY__CONTENT'`	Define the template for overlay content.
