从控制台调用coffeescript函数 [英] Calling coffeescript functions from console

问题描述

使用coffeescript和Rails 3.1.0.rc4玩一点。有此代码：

  yourMom =（位置） - > 
 console.log location 
 
 yourMomwuz hur
  

当页面加载时，这将正确输出wuz hur。但是当我尝试调用

  yourMom（wuz hur）
  pre> 
 
 
从chrome js控制台（我有时测试正常的JS函数），我得到一个ReferenceError：yourMom未定义
 
 
 
由coffeescript生成的函数是否可以这种方式提供？ 
解决方案
一个更简单的方法来共享全局方法/变量是使用@这意味着这。
  @yourMom =（位置） - > 
 console.log location 
 
 yourMomwuz hur
  
 Nicer语法和更容易阅读，但我不鼓励你创建全局方法/变量
 
Playing a little with coffeescript and Rails 3.1.0.rc4.  Have this code:
yourMom = (location) ->
  console.log location

yourMom "wuz hur"
When the page loads, this outputs "wuz hur" properly.  But when I try to call
yourMom("wuz hur")
from the chrome js console (as I do sometimes to test normal JS functions), I get a "ReferenceError: yourMom is not defined"

Are functions generated by coffeescript available in this way?  
解决方案
an easier way to share global methods/variables is to use @ which means this.
@yourMom = (location) ->
  console.log location

yourMom "wuz hur"
Nicer syntax and easier to read, but I don't encourage you to create global methods/variables
