javascript - coffeescript class - calling calling one class method from an other -

i have rewritten embedded js in rails app coffeescript..and new coffeescript...

my approach mix of these articles:

• approach one

• approach two

my code:

s = undefined class app.photolike    settings:     modalelement: $('#mymodal')     likebuttonid: '#like'     photo_id: $('.image_info').attr('photo_id')     numberoflikes: $('#likes_num')    constructor: (@el) ->     console.log('constructor called')     s = @settings     @binduiactions()     return     binduiactions: ->     console.log('binduiactions called')     $('#mymodal').on 'click', '#like', -> likephoto()     $(document).on "page:change", -> pagechange()     pagechange: ->     console.log('pagechange called')     photo = new app.photo    likephoto: ->     console.log('likephoto called')     url = '/photos/' + s.photo_id + '/like'     $.get url, (data) ->       s.numberoflikes.html data['likes'] + ' likes'       $(s.likebuttonid).toggleclass 'btn-success' 

this part of model gets loded ajax , once call succeeds create above class (instance of):

new (app.photolike) 

my problem. modal gets loaded seems good. when trigger event:

$('#mymodal').on 'click', '#like', -> likephoto() 

i get:

photo.like.self-942fcd8….js?body=1:25 uncaught referenceerror: likephoto not defined 

so, not know likephoto function. have tried calling this.likephoto , @likephoto, refers button element triggers event.

so how do this? other approaches welcome. not sure need classes...but want structured code...

likephoto() function of our object/class app.photolike. , you're calling local function.

you can instead

binduiactions: ->   _this = #this change inside, have have reference our object here   console.log('binduiactions called')   $('#mymodal').on 'click', '#like', -> _this.likephoto()   ... 

let me know if works.
