How do you pass an argument to the Google Apps Script debugger?
提问by Menasheh
Say I have the following broken example function in a google-apps script. The function is intended to be called from a google sheet with a string argument:
假设我在 google-apps 脚本中有以下损坏的示例函数。该函数旨在从带有字符串参数的谷歌表中调用：
function myFunction(input) {
var caps = input.toUpperCase()
var output = caps.substrin(1, 4)
return output
}
While this example script should break on line 3 when you select myFunction and press debug, as there is no such method as "substrin()," it will break on line 2, because you can't put undefined in all caps:
当您选择 myFunction 并按 debug 时，这个示例脚本应该在第 3 行中断，因为没有像“substrin()”这样的方法，它会在第 2 行中断，因为您不能将 undefined 放在所有大写中：
TypeError: Cannot call method "toUpperCase" of undefined. (line 2, file "Code")
类型错误：无法调用未定义的方法“toUpperCase”。（第 2 行，文件“代码”）
Question:Is there an official way to pass a string to a google-apps script for testing/debugging without making an additional function
问题：是否有一种官方方法可以将字符串传递给 google-apps 脚本以进行测试/调试，而无需创建附加功能
function myOtherFunction() {
myFunction("testString")
}
and debugging that?
和调试？

The function as you wrote it does need a parameter and there is no way to avoid that except by including a default value in the function itself. See example below
您编写的函数确实需要一个参数，并且无法避免这种情况，除非在函数本身中包含一个默认值。请参阅下面的示例
function myFunction(input) {
input= input||'test';
var caps = input.toUpperCase();
var output = caps.substrin(1, 4);
return output;
}
