This provides asynchronous alternatives to alert, confirm and prompt.

If you're not using Rails, just grab the sources from lib/assets. If you're not using CoffeeScript, you can always convert the sources to JavaScript in the "Try CoffeeScript" tab in coffeescript.org.

Otherwise, just add "gem 'common-dialogs'" to your Gemfile and run bundle.

It also depends on jQuery-UI being installed. I recommend the jquery-ui-themes gem.

Then require the bundled assets after requiring jQuery UI.

For example, if you're using the jquery-ui-themes gem, your application.js would look like this:

//= require jquery
//= require jquery_ujs
//= require jquery-ui
//= require common-dialogs
CommonDialogs.require() // remove this if you don't want to add the helpers to the window object

And in application.css (see the supported themes list in the link above):

/*
= require jquery-ui/smoothness
= require common-dialogs
*/

showMessage 'Any message' # Dialog title is "Message" by default
showMessage 'Any message', title: 'Dialog Title', onClose: (-> console.log 'closed'), additionalClasses: 'success popup'
# the CSS classes in additionalClasses will be added to the dialog div
# All dialogs support those options.
showError 'An error message with alert icon'
confirmDialog 'Really remove task?', (-> console.log 'confirmed'), noAction: -> console.log 'answered no - this option is not required'
inputDialog 'What is your name?', ((name)-> console.log "Your name is #{name}"),
  initialValue: 'Optional initial value'
  required: false # true by default, which means that an empty string is not allowed by default
  cancelAction: (-> console.log 'cancel was called - this option is not required')

Feel free to change the default messages and button names by changing the CommonDialogs.defaults object. Just inspect it (console.log(CommonDialogs.defaults)) to see what keys to change and what are their default values.
