Usage

The basic setup for one modal with default options is the following.

<div id="modal-1">
    <!-- the modal content goes here -->
</div>

new Modaly("#modal-1");

To open the modal add the data-modaly-open attribute to any DOM element.

<button data-modaly-open="#modal-1">
    Open Modal
</button>

To close the modal add the data-modaly-close attribute to any element inside the modal.

<div id="modal-1">
    <!-- the modal content goes here -->

    <img src="close-icon.svg" data-modaly-close />
</div>

You can open/close the modal programmatically.

const modal = new Modaly("#offer-modal");

if (offersAvailable) {
    modal.show();
}

const modal = new Modaly("#timeout-modal");

setTimeout(() => modal.hide(), 5000);

Options

You can further customize the behaviour and looks of your modals.

new Modaly("#modal-custom", {
    // Style
    background: "black",
    opacity: 0.75,
    duration: 250,
    animation: "ease-in",

    // Navigation
    escape: true,
    overlay: true,
    accesible: true,

    // Callbacks
    onShow: (modal, trigger) => {},
    onHide: (modal, trigger) => {}
});

If the initial microsecond where the modal flashes is a problem, you can always add the display none attribute.

<div id="modal-1" style="display: none">
    <!-- the modal content goes here -->

    <img src="close-icon.svg" data-modaly-close />
</div>

Callbacks

onShow(modal, trigger)

Fired when the modal it is about to open.

• modal: the modal DOM element.
• trigger: which DOM element openned the modal. null if no DOM element triggered it.

onHide(modal, trigger)

Fired when the modal it is about to close.

• modal: the modal DOM element.
• trigger: which DOM element closed the modal. null if no DOM element triggered it.

Lazy Loading

Since version 0.5.0 you can lazy load the resources inside the modal when it opens. This comes in handy when dealing with image slideshows libraries that do not support this feature.

To use it, as in many other libraries, simple add the data-src attribute to the resource you want to lazy load.

If you use your own lazy loading, you can disable it by setting to false the lazyLoading options parameter.

Accessibility

If the option accesible is true, accessibility attributes will be added to the modal and the close triggers automatically.

It will change from this.

<div id="modal-1">
    <!-- modal content -->

    <img src="close-icon.svg" data-modaly-close />
</div>

To this. The aria-hidden attribute will toggle accordingly to the modal.

<div id="modal-1" role="dialog" aria-modal="true" aria-hidden="true">
    <!-- modal content -->

    <img src="close-icon.svg" data-modaly-close aria-label="close this dialog"/>
</div>
