A CasperJS wrapper for remote jQuery calls (untested)

gistfile1.coffee

class jQueryCasperWrapper
  constructor: (@selector) ->
    wrappedMethods = ['data', 'visible'] # ... plus all the other jQuery functions being wrapped
    
    _.each(wrappedMethods, (method) => # lodash/underscore foreach -- just from my own preferences
      wrapper = (args...) => @RemotejQuery(method, args)
      @[method] = wrapper
    )

  RemotejQuery: (methodName, args) ->
    remote_fn = (_selector, _methodName, _args) ->
      jobj = jQuery(_selector)
      return jobj[_methodName].apply(jobj, _args)
      
    casper.evaluate(remote_fn,
      _selector: @selector
      _methodName: methodName
      _args: args
    )
      

jQueryInCasper = (selector) ->
  return new jQueryCasperWrapper(selector)
  
casper.$ = jQueryInCasper

# now we can do casper.$("hello").data() or casper.$("#header").text()
