我的错误

我试过了两个
bindAll (因上述错误而失败)和 bind(不工作)window.test = Backbone.View.extend({
collection: null
initialize: ->
console.log('initialize()')
console.log(this)
# _.bindAll(this, ["render", "foo"])
_.bind(this.render, this) # these don't throw errors, but binding won't work
_.bind(this.foo, this)
@collection = new Backbone.Collection()
@collection.bind "add", @render
@collection.bind "add", @foo
@render()
foo: ->
# won't be bound to the view when called from the collection
console.log("foo()")
console.log(this)
console.log(this.collection) # undefined (since this is the collection, not the view)
render: ->
console.log("render()")
console.log(this)

尝试转换字符串会产生以下结果:
Iconv.conv("UTF-8", "ISO-8859-2", "Stefan,Engstr\232m")
=> "Stefan,Engstrm"

如果我应该提供更多信息或详细说明某些事情,请告诉我.
什么样的 JSON 可能导致 Opera 12(在其他浏览器中不会发生)抛出以下错误:
SyntaxError: JSON.parse: Illegal number format (trailing decimal dot)
客户告诉我他们收到了这个错误,但由于他们的技术水平不是很高,所以我无法引导他们足够远来挖出字符串。我尝试自己重现该错误,但到目前为止还没有成功。因此,我不知道导致此问题的 JSON 字符串。
