Adding a function call on the end of function in coffeescript

问题

Any ideas on how to write this as coffeescript?

Person = Ember.Object.extend({
  // these will be supplied by `create`
  firstName: null,
  lastName: null,

  fullName: function() {
    var firstName = this.get('firstName');
    var lastName = this.get('lastName');

   return firstName + ' ' + lastName;
  }.property('firstName', 'lastName')
});

I'm particularly interested in the }.property part of the code. I can't figure out how to write this in coffeescript.

回答1:

personally, i like braces around my functions:

Person = Ember.Object.extend(
  firstName: null
  lastName: null
  fullName: (->
    firstName = @get("firstName")
    lastName = @get("lastName")
    firstName + " " + lastName
  ).property("firstName", "lastName")
)

my head can better parse this ;-)

first jsbeautifier it, then js2coffee it:

Person = Ember.Object.extend(
  firstName: null
  lastName: null
  fullName: ->
    firstName = @get("firstName")
    lastName = @get("lastName")
    firstName + " " + lastName
  .property("firstName", "lastName")
)

As they say,make your code right.
