How to Pass Variables from Code.gs to Included Script Snippets in Google Apps Script
When working with Google Apps Script, particularly when combining server-side code with client-side HTML, you might encounter a challenge: how to pass variables from your Code.gs file to included script snippets. This guide will guide you through the steps needed to achieve this efficiently, allowing you to utilize shared data in your HTML templates seamlessly. Let's get started!
Understanding the Problem
First, let's outline the scenario. You have a Google Apps Script that includes HTML templates, and you want to pass variables from your server-side script (Code.gs) to these templates. You typically set a variable like data using the following code:

Then you can call this variable in your HTML template using:

However, this becomes tricky when you include additional script snippets using an include function, which looks something like this:

When you include a script in your HTML, like so:

The big question arises: How do I access that data variable in the included DataHandler script?
The Solution: Modifying the Include Function
To tackle this problem, you need to modify the include function to allow data to be passed along. Here's how you can do it:
Step 1: Change the Include Function
You will need to adjust your include function to accept additional parameters so that you can evaluate the variable inside the template correctly. Here’s the updated function:

Step 2: Pass the Variable When Calling Include
Next, when you call include, you’ll need to provide the variable you want to pass along. Here is an example of how to include your DataHandler script with the data variable:

In this instance, you are not only passing the variable data, but you can also include any other data that you may need within that script snippet.
Example of Usage in DataHandler
Now, with the data passed through, you can access it inside your DataHandler script as follows:
