Question

我正在尝试解决此练习，其中所有输出必须显示在终端上。

任务

您仍然会获得要转换的输入字符串。但是，这一次，您还可以使用套管样式。以下代码块将描述要支持的所有外壳样式。您可能还会收到一系列套管样式，并且应该应用每种样式。

每种套管样式的优先顺序如下，应首先处理列表中较高的值：

骆驼，帕斯卡，蛇，烤肉串，头衔元音辅音上，下

测试和输出应如下：

makeCase("this is a string", "camel") === "thisIsAString";

makeCase("this is a string", "pascal") === "ThisIsAString";
makeCase("this is a string", "snake") === "this_is_a_string";
makeCase("this is a string", "kebab") === "this-is-a-string";
makeCase("this is a string", "title") === "This Is A String";
makeCase("this is a string", "vowel") === "thIs Is A strIng";
makeCase("this is a string", "consonant") === "THiS iS a STRiNG";
makeCase("this is a string", ["upper", "snake"]) ==="THIS_IS_A_STRING";

这是我到目前为止提出的代码。道歉很长。我正在学习javascript并且是一个菜鸟。

      // **************************************TIER 2 AND 3 FONTS ********************************

      else if (font.constructor === Array)
      {
        switch (font)
        {
          // How do I join cases togather and combine my functions when multiple styles are needed?
        }
      }


      }

基本上我需要弄清楚当要求2种样式/字体时如何应用正确的字体。提前致谢

Answer 1

在同一输入上调用多个功能

var functions = {
    pascal: (input) ->
       ...
    uppercase: (input) ->
       ...
}

if (typeof font !== 'array') {
    font = [font]
}

$.each(
    font,
    (fontType) ->
        input = functions[fontType]();
);

旁注：

所有函数基本上都是一样的，所以字体应该只定义是否需要保持字母大小写和分隔符（思维边缘情况，如camelCase）
