Ruby on Rails unobtrusive scripting adapter.
|
|
========================================
|
|
|
|
This unobtrusive scripting support file is developed for the Ruby on Rails framework, but is not strictly tied to any specific backend. You can drop this into any application to:
|
|
|
|
- force confirmation dialogs for various actions;
|
|
- make non-GET requests from hyperlinks;
|
|
- make forms or hyperlinks submit data asynchronously with Ajax;
|
|
- have submit buttons become automatically disabled on form submit to prevent double-clicking.
|
|
|
|
These features are achieved by adding certain ["data" attributes][data] to your HTML markup. In Rails, they are added by the framework's template helpers.
|
|
|
|
Requirements
|
|
------------
|
|
|
|
- HTML5 doctype (optional).
|
|
|
|
If you don't use HTML5, adding "data" attributes to your HTML4 or XHTML pages might make them fail [W3C markup validation][validator]. However, this shouldn't create any issues for web browsers or other user agents.
|
|
|
|

|
|
------------
|
|
|
|
Run `npm install rails-ujs --save` to install the rails-ujs package.
