class MyClass
defaultOptions:
url: '/photos.json'
constructor: (@element, @options) ->
@photos = []
@init()
addPhotos: (photo) ->
@photos.push photo
request: ->
$.getJSON(this.defaultOptions.url).done((data) ->
@addPhotos data
return
).fail (jqxhr, textStatus, error) ->
err = textStatus + ', ' + error
console.log 'Request Failed: ' + err
return
init: ->
@request()
實例方法。當我從控制檯爲什麼不能調用裏面方法
var myClass = new MyClass("#myElement")
我得到這個錯誤
TypeError: this.addPhotos is not a function. (In 'this.addPhotos(data)', 'this.addPhotos' is undefined)
任何想法,爲什麼我不是能夠調用運行此命令請求方法內部的addPhotos方法,我怎麼稱呼它?
