How to use the Dictionary javascript class in Google Apps Script?
提问by user1935166
I am trying to make and use a Dictionary object in Google Apps Script. Before, I used a very long switch statement for my script the first time around, and when I submitted it to the Gallery, the person who approved it asked why I didn't use a Javascript Dictionary object instead. I looked into how to use Dictionary objects, but now my script wont' work because Google Apps Script doesn't understand the command:
我正在尝试在 Google Apps Script 中创建和使用 Dictionary 对象。之前，我第一次在我的脚本中使用了很长的 switch 语句，当我将它提交给 Gallery 时，批准它的人问我为什么不使用 Javascript Dictionary 对象来代替。我研究了如何使用 Dictionary 对象，但现在我的脚本无法运行，因为 Google Apps 脚本不理解命令：
Components.utils.import("resource://gre/modules/Dict.jsm");
This 'import' line of code was copied straight from this Javascript Reference webpage: http://developer.mozilla.org/en-US/docs/Mozilla/JavaScript_code_modules/Dict.jsm
这行“导入”代码直接从这个 Javascript 参考网页复制而来：http: //developer.mozilla.org/en-US/docs/Mozilla/JavaScript_code_modules/Dict.jsm
How do I include this javascript library needed to make it work, or what is the Google Apps Script alternative to a javascript Dictionary object?
我如何包含使其工作所需的这个 javascript 库，或者什么是 javascript Dictionary 对象的 Google Apps Script 替代方案？

Any time you've got a switchstatement that looks something like:
任何时候你有一个switch看起来像这样的语句：
switch ( someValue ) {
case "string1": doSomething( valueForString1 ); break;
case "string2": doSomething( valueForString2 ); break;
// ...
case "stringN": doSomething( valueForStringN ); break;
}
you can replace that with:
您可以将其替换为：
var dict = {
"string1": valueForString1,
"string2": valueForString2,
// ...
"stringN": valueForStringN
};
doSomething( dict[ someValue ] );
The values can be anything, of course: strings, numbers, objects, functions, whatever. And you probably would want to check for a value being missing from the dictionary:
当然，值可以是任何东西：字符串、数字、对象、函数等等。您可能想要检查字典中是否缺少某个值：
if (dict[someValue]) doSomething(dict[someValue]);
