jquery-rails

jQuery! For Rails! So great.

This gem provides:

• jQuery 1.9.0
• jQuery UI 1.9.2 (javascript only)
• the jQuery UJS adapter
• assert_select_jquery to test jQuery responses in Ruby tests

下面还有

For jQuery UI, we recommend the jquery-ui-rails gem, as it includes the jquery-ui css and allows easier customization. This gem still packages the jQuery UI javascript for compatibility. To use it, add the following line to your application.js:

//= require jquery-ui

推荐 jq-ui 的地址
