Question

我试图通过使用CoffeeScript拆分逗号将字符串拆分为数组元素。

stringArray = string.split(',')
for element in stringArray
    console.log element

我遇到的问题是，在迭代数组时，某些组件没有得到控制台记录。我期望输出9个子串，因为有8个逗号。

相反，输出5个元素，而不输出4个元素。它们不会附加到其他元素或类似的东西上，只是缺失。

这是我试图解析的字符串，粗体元素是行为不端的元素：

非常感谢任何输入！

解决

原来这是一个下游问题。我有if语句使用'return'，认为它会继续迭代，而它实际上只是终止它。用'continue'替换那些'return'语句并且它有效。感谢所有关于问题和问题格式的输入！

您的代码按原样运行。这是编译好的JS：

  console.log(element);
}

我只是将您的代码投入CoffeeScript.org's "Try It" feature。
