Enable Sequential Button Clicks in Django Forms

Managing user interactions with forms can be complex, especially when specific sequences of actions are required. If you have a Django form with two buttons, "Get Price" and "Order Now", you may face a situation where users bypass the necessary first step. This post addresses how to enforce a click sequence—ensuring users get the price before proceeding to place an order.

The Problem

Imagine you have a form where users fill in their details, and at the bottom, there are two buttons:

Get Price: Fetches the pricing information based on user input.

Order Now: Redirects users to place an order.

However, some users might directly click Order Now without first clicking Get Price. This disrupts the flow and could lead to confusion. We need a solution to ensure that when users click Order Now, it automatically triggers the "Get Price" action first.

The Solution

To provide a seamless experience without requiring page reloads, we can utilize jQuery to manage the button clicks and AJAX for getting the price. Here’s how to approach this step-by-step.

Steps to Implement

Basic HTML Structure: Start by creating a simple form structure with the necessary buttons.

2. Add jQuery for Button Interactivity

Next, we need to include jQuery and add a script to handle the button actions.

3. Explanation of the Script

get-price and order-now: Both buttons are now types of button instead of submit to prevent page reloads on click.

getPrice function: This function simulates an API call to fetch pricing information and updates the price displayed in the span. Once the price is fetched, it resolves the promise.

Order Logic: After getting the price, clicking Order Now will redirect the user to the order page.

Conclusion

By implementing the outlined solution, you ensure that users must click Get Price before moving on to place an order. This approach leverages jQuery and AJAX to create a more responsive user experience without unnecessary page reloads.

Enforcing user behavior like this can greatly enhance usability and reduce confusion. Feel free to adapt the scripts to fit the specifics of your Django application and enjoy a smoother user journey!
