从控制台调用 coffeescript 函数
使用 coffeescript 和 Rails 3.1.0.rc4.有这个代码:
Playing a little with coffeescript and Rails 3.1.0.rc4. Have this code:
yourMom = (location) ->
console.log location
yourMom "wuz hur"
当页面加载时，这会正确输出wuz hur".但是当我尝试打电话时
When the page loads, this outputs "wuz hur" properly. But when I try to call
yourMom("wuz hur")
从 chrome js 控制台(就像我有时测试正常的 JS 函数一样)，我收到ReferenceError: yourMom is not defined"
from the chrome js console (as I do sometimes to test normal JS functions), I get a "ReferenceError: yourMom is not defined"
coffeescript 生成的函数可以这样使用吗?
Are functions generated by coffeescript available in this way?
推荐答案
共享全局方法/变量的更简单方法是使用@，这意味着.
an easier way to share global methods/variables is to use @ which means this.
@yourMom = (location) ->
console.log location
yourMom "wuz hur"
更好的语法和更容易阅读，但我不鼓励你创建全局方法/变量
Nicer syntax and easier to read, but I don't encourage you to create global methods/variables
