How to Access mainFunction in an Imported JavaScript Object in Odoo

Working with Odoo applications involves extending functionalities, and sometimes, you may encounter challenges when trying to access functions from your imported objects. This guide addresses a common problem: How to run a function from an imported object and access its internal function?

Let's dive into the details and explore the solution step-by-step.

The Problem Explained

Imagine you have two JavaScript files in your Odoo application: file_a.js, which contains a parent function and an internal function, and file_b.js, where you want to access these functions. Below is an illustrative snippet from file_a.js:

In file_b.js, you import file_a.js:

At this point, you recognize that mainFunction is indeed a function, but you're struggling with two critical questions:

How do I access what is being returned by mainFunction?

How do I access _internalFunction from within parentFunction?

Understanding the Solution

To solve these issues, we need to modify the way parentFunction works. This is how you can achieve it:

Step 1: Modify parentFunction

Currently, parentFunction doesn’t return anything. To access _internalFunction, you must return it from parentFunction. Here’s how you can modify it:

Step 2: Accessing Internal Function

After you modify parentFunction as mentioned above, you can now access the internal function like this:

Step 3: Summary of Changes

To recap, you need to follow these steps:

Ensure parentFunction returns the internal function.

When you call mainAction.mainFunction(), it will now give you access to _internalFunction, allowing you to invoke it and get the value of someValue.

Conclusion

By making the described adjustments, you solve the access issues with functions in your Odoo application. This process not only enhances your understanding of JavaScript function scope but also enriches your capability to extend Odoo services effectively.
