Some helper methods to perform standard JS library tasks from js.erb without having to write actual javascript
To install the plugin in your Rails 2.3 application, simply run
ruby script/plugin install https://github.com/Stex/rjs_helpers.git
This will automatically load the Rails helper into all your controllers. As explained below, the plugin ships with a default JS adapter for jQuery which can be automatically copied to your public/javascripts directory with the following line:
ruby script/generate rjs_helpers js
Now you only have to include this js file into your application layout and you're good to go.
The plugin consists of two parts:
- A Rails helper which is available in application views
- A JS helper library which has to be included into your application scripts / layout
The JS file which is part of this plugin uses jQuery to perform its tasks. If your application is using a different framework, feel free to write an own adapter for it.
The Rails helper does not directly generate code for just one library, as jQuery might not be used for all applications. Instead, it will generate calls to an own API which can be found in the included javascript file.
