从HTML输入返回应用程序脚本中的数据 [英] returning data in app script from an HTML input

问题描述

我正在尝试使用HTMLService从Google电子表格中放出html表单，并从选择输入中将数据返回到脚本.我正在使用以下行收集数据: -

I am trying to lauch an html form from a google spread sheet using the HTMLService and return data to the script from a select input. I am collecting the data with this line: -

但是我不确定如何将其返回到脚本文件:我尝试了以下各种迭代: -city = form.Projects_list.text; -city = form.Projects_list [0]; -city = form.Projects_list.[0] [0];

But I am not sure how to get it back to the script file: I have tried various iterations of: - city= form.Projects_list.text; - city= form.Projects_list[0]; - city= form.Projects_list.[0][0];

但是这些似乎都不是选择的正确方法.其他变量将从表格中返回.

but none of these seem to be the right handle to the select. The other variables are coming back from the form as desired.

如何获取最后一个变量?

How can I grab that last variable?

推荐答案

您可以使用value属性.

You can use the value attribute.

document.getElementById("Projects_list").value
