Getting started

CDN

Place the latest production bundle before the closing </body> and call dialog init:

<script src="https://unpkg.com/dimmer"></script>
<script>
  var dialog = dimmer();
  dialog.init();
</script>

Download

Download dimmer.js or minified production ready dimmer.min.js. Place it before the closing </body> and call dialog init:

<script src="script/dimmer.min.js"></script>
<script>
  var dialog = dimmer();
  dialog.init();
</script>

NPM

Install package with npm install dimmer. Call init:

import dimmer from 'dimmer';

const dialog = dimmer();
dialog.init();

Usage

Use data attributes to declare dialog trigger and markup.

<button type="button" data-dialog-open="foo">Open info dialog</button>

<div data-dialog="foo" style="display: none;">
  <h3>Foo dialog</h3>
  <a href="#" data-dialog-close>Close this dialog</a>
</div>

You can pass valid JSON via data-dialog-payload attribute. Below given JSON fields payloads will be injected upon dialog showing.

<button
  type="button"
  data-dialog-open="foo"
  data-dialog-payload='[{"field": "title", "type": "text", "payload": "Foo"}, {"field": "input", "type": "value", "payload": "bar"}]'
>Open foo dialog</button>

<div data-dialog="foo" style="display: none;">
  <h3 data-dialog-field="title"></h3>
  <input
    type="text"
    data-dialog-field="input"
  >
  <a href="#" data-dialog-close>Close this dialog</a>
</div>

See Examples.
