CoffeeScript 中的解析错误 +骨干保存功能
我正在尝试将 CoffeeScript 与 Backbone.js （通过 Brunch）结合使用，并且想在模型中实现保存功能，但它拒绝编译，我一直无法弄清楚原因。我需要将参数传递到保存函数并实现回调。
下面的代码在第二行给出了 Unexpected ':' 错误，但我不确定为什么：
class exports.Tag extends Backbone.model
defaults:
id: null
tagId: null
found: false
location: "Not yet found..."
finders: []
pointValue: 0
unlockCode: ""
verifyCode = ( code ) ->
@save { tagId: @get 'tagId', unlockCode: code },
success: ( model, response ) ->
@trigger 'verifySuccessful', response
error: ( model, response ) ->
@trigger 'verifyFailed', response
任何帮助表示赞赏...谢谢！
I'm trying to use CoffeeScript with Backbone.js (via Brunch) and I want to implement a save function in my model, but it refuses to compile and I have been unable to figure out why. I need to both pass parameters into the save function and implement callbacks.
The code below gives an Unexpected ':' error on the second line, but I'm not sure why:
class exports.Tag extends Backbone.model
defaults:
id: null
tagId: null
found: false
location: "Not yet found..."
finders: []
pointValue: 0
unlockCode: ""
verifyCode = ( code ) ->
@save { tagId: @get 'tagId', unlockCode: code },
success: ( model, response ) ->
@trigger 'verifySuccessful', response
error: ( model, response ) ->
@trigger 'verifyFailed', response
Any help appreciated...thanks!

就在这里，你正在混淆解析器
是这个吗？
还是这个？
两者都可以修复错误，但它们显然意味着不同的事情。
我想补充一点，隐式括号确实很棒，但只有在最简单的情况下才能利用它。我通常使用的规则是省略一行中第一个函数调用的括号，并将它们用于所有其他函数。这条规则可以让你完全摆脱这个问题。
It's here, you are confusing the parser
Is that this?
Or this?
Either will fix the error, but they obviously mean different things.
And might I add, implicit parens are indeed awesome, but take advantage of that awesome only in the most simple of circumstances. A rule I usually use is that omit parens for the first function invocation in a line, and use them for all others. This rule would have saved you from this issue entirely.
