How to Get EJS Value Based on a JavaScript Variable in Your Booking System

Creating an appointment booking website can be a bit tricky when it comes to managing dynamic data between your server and client-side. If you’re using Express, EJS, and Axios, you might have encountered a situation where you need to access certain values based on user interaction. For instance, you want to get the doctor_id from your EJS-rendered content when the user clicks a 'Book' button. In this guide, we’ll break down how to achieve this using a structured approach.

The Challenge

When working with EJS and JavaScript, it's important to remember that EJS is a templating engine that renders HTML on the server-side before it reaches the client. This means that accessing dynamically loaded values—you might want a doctor_id associated with a button click—can present some challenges. The original approach of trying to fetch the ID directly using the i index from your JavaScript might not work as expected.

The Solution

To effectively get the doctor_id when a 'Book' button is clicked, you can add some additional data attributes to the buttons and utilize JavaScript to fetch and use those values. Here’s how to tackle this step-by-step.

Step 1: Modify Your Button with Data Attributes

Firstly, you need to include the doctor_id as an attribute on your button. This can be achieved using the data-doctor-id attribute.

Step 2: Retrieve the Doctor ID in JavaScript

In your JavaScript, you can now easily access this value when a button is clicked. Here’s how to implement that:

Step 3: Consume the Doctor ID in Your Date Selection Method

When the user selects a date, you’ll want to send the doctor_id alongside the selected date. This can be done in the sendSelectedDate function:

Conclusion

By efficiently leveraging data attributes and modifying your JavaScript functions, you can dynamically manage data between your EJS and client-side code. This approach not only resolves the issue of accessing doctor_id dynamically but also streamlines user interaction within your appointment booking system.

Implementing these strategies will significantly enhance the way you handle event-based data management in your web applications. Happy coding!
