Uniform
I present to you a ViewController for the browser. A
ViewController (in this case) is a class that describes the
behaviour of an element and it's children. It goes well with
jQuery but can use whatever you like.Here's an example:
# Let's describe a contact form
class ContactForm extends Uniform
# The HTML template
template: """
<form>
<textarea></textarea>
<button>Send</button>
</form>
"""
# On initialise we want to add the form to the body
init: -> $('body').append(@el)
# We cache some children to properties on this object
elements:
msg: 'textarea'
btn: 'button'
# We delegate the submit event to @sendResponse()
events:
'': # This empty string means attach to thyself
'submit': 'sendResponse'
# Do the sending :)
sendResponse: (el, e) ->
e.preventDefault()
@btn.text('Sending...')
$.post 'index.html', msg: @msg, =>
@msg.val('')
@btn.text('Send')
# Initialise
jQuery -> new ContactForm
You can also use your ViewControllers on elements already in the DOM like so:
# Or use on an existing element
jQuery -> new ContactForm(el: $('#contact'))
CoffeeScript in the browser?
Uniform is best used in compiled CoffeeScript browser environments. Since Uniform is a CoffeeScript class it is easiest to extend and use it if your front end code is also CoffeeScript.Use it how you like though.
