Code: add HTML5 form input types, validation constraints & WAI-ARIA/accessibility to Jeditable

[nfreear]

I've just started using Jeditable for a project. I suggest it will continue to be very useful, despite or because of HTML5. The new input types ("number", "email" etc.) and form validation potential may be more powerful and usable in the long term than HTML5's contenteditable.

I'm proposing and implementing a plugin for Jeditable, which will start to implement HTML5 forms. It will also add some accessibility improvements, notably for keyboard accessibility, using WAI-ARIA.

New function:

• $(selector).editableAriaShim()

Other details, see pull request #87.
