@oddbird/popup-polyfill v0.0.2

popup polyfill

Explainer

This polyfills the HTML popUp attribute and showPopUp/hidePopUp methods onto HTMLElement.

Polyfill Installation

Download a copy

The simplest, recommended way to install the polyfill is to copy it into your project.

Download popup.iife.min.js from unpkg.com and add it to the appropriate directory in your project. Then, include it where necessary with a <script> tag:

<script src="/path/to/popup.iife.min.js" type="module"></script>

You will also likely need the CSS file, which supplies some default styles. Download the popup.css from unpkg.com and add it to the appropriate directory in your project. Then, include it where necessary with a <link rel=stylesheet> tag:

<link rel="stylesheet" src="/path/to/popup.css" />

With npm

For more advanced configuration, you can install with npm:

npm install @oddbird/popup-polyfill

After installing, you’ll need to use appropriate tooling to use node_modules/@oddbird/popup-polyfill/dist/index.js (or .min.js).

You will also likely need to include the CSS stylesheet which is found in node_modules/@oddbird/popup-polyfill/dist/popup.css.

If you want to manually apply the polyfill, you can also import the isSupported and apply functions from node_modules/@oddbird/popup-polyfill/dist/popup.js file.

Via CDN

For prototyping or testing, you can use the npm package via a Content Delivery Network. Avoid using JavaScript CDNs in production, for many good reasons such as performance and robustness.

<script
  src="https://cdn.jsdelivr.net/npm/@oddbird/popup-polyfill@latest"
  crossorigin="anonymous"
  defer
></script>

Usage

After installation the polyfill will automatically add the correct methods and attributes to the HTMLElement class.
