如何在 CoffeScript 中将两个匿名函数作为参数传递? [英] How to pass two anonymous functions as arguments in CoffeScript?

问题描述

我想传递两个匿名函数作为 jQuery 悬停的参数，如下所示:

I want to pass two anonymous functions as arguments for jQuery's hover, like so:

$('element').hover(
  function() {
    // do stuff on mouseover
  },
  function() {
    // do stuff on mouseout
  }
);

只需一个 - hover -> 就很容易 - 但是 CoffeeScript 中两个的正确语法是什么?我试过 ...hover ->、...hover( ->... 等，但没有任何东西让我得到上述结构.

It's easy with just one – hover -> – but what is the proper syntax in CoffeeScript for two? I tried ...hover ->, ...hover( ->..., etc. but nothing gets me the above structure.

推荐答案

在匿名函数周围加上括号.

Put parentheses around the anonymous functions.
