'data-cookie-notice' HTML attribute, other suggestions / wishlist

[nfreear]

Hi,

I've got some suggestions for improvements that I hope will benefit most users ... I'll create pull requests as I work through some of these.

Proposed changes / "wishlist"

1. — DONE. Allow configuration options to be set via JSON in a data-cookie-notice HTML attribute on a <script> element, pull Add support for data-cookie-attribute #5;
2. — DONE. Add Travis-CI build and test (qunit etc.), pull Add Travis-CI automated tests #1, Follow-up to pull #1 - move jQuery to devDependencies for clarity #2;
3. — Add semistandard / ESLint-type tests — Flet/semistandard;
4. — Accessibility testing and fixes, using e.g. pa11y-ci or grunt-rsids-pa11y;
5. — Move CSS from style attribute to <style> element, or separate stylesheet — create <style> or <link> via the Javascript — make it easier to override styles;
6. — Document use of a CDN, e.g. https://unpkg.com in the README;
7. — Improve the language used in the English translation ;);
8. … ?

Aims

While working on the proposed fixes, the aim is to:

1. Maintain the current small size of the Javascript — as near as possible (currently 3.36 kB minified; 9.1 kB un-minified);
2. Keep the existing straightforward Javascript-based API;
3. New easy-to-use non-Javascript API (data attribute);

See notes on Google Docs.

Example HTML

Here is an example of using the proposed data-cookie-notice attribute:

<script
  data-cookie-notice='{ "learnMoreLinkEnabled": true, "learnMoreLinkHref": "/privacy.html" }'
  src="https://unpkg.com/cookie-notice@^1/dist/cookie.notice.min.js"
 ></script>
