空值应用程序脚本 google 表单
Empty Values apps script google forms
我有一个 google 表单的触发器 onFormSubmit。我想知道某个特定的下拉列表是否有答案。假设我有以下形式的代码和我的形式中名称为 Country2
的下拉列表
function onFormSubmit(e) {
var AnswerObject = e.namedValues();
var NumCountries = 1;
if (namedValues("Country2") != // something goes here {
NumCountries++;
}
这个值应该是 "" 或 null 还是其他?
来自https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/if...else
Any value that is not undefined, null, 0, NaN, or the empty string
(""), and any object, including a Boolean object whose value is false,
evaluates to true when passed to a conditional statement.
考虑到以上情况,尝试类似的方法:
if (namedValues("Country2")) {
NumCountries++;
}
