Building a Pricing Calculator with Selects and Webflow Form

In this tutorial, we will walk through the process of creating a pricing calculator using select inputs and a Webflow form. This calculator will allow users to select various options, add up the total cost, and then submit the total cost along with the form.

Setting Up Select Inputs in Webflow

Adding Select Inputs

To begin, let's create two select field inputs on the web page within Webflow. These select inputs will allow users to make selections that will contribute to the total cost calculation.

To add a select input in Webflow:

1. Drag and drop a dropdown component onto the canvas.
2. Customize the options within the dropdown to reflect the various choices available for selection.

Applying Values to Select Options

Next, for each option within the select inputs, we need to assign a value to them. This value will be used to calculate the total cost based on the user's selections.

In Webflow:

1. Click on each select input to access its options.
2. For each option, set both the display text and the value. The display text is what the user will see, and the value will be used for calculations.
3. Ensure that each option has a value assigned. These values will be used to tie the selections to their respective costs.

By assigning values to the select options, we can effectively correlate the user's choices to their associated costs.

Creating the Pricing Calculator Functionality

Select Classes and Data Attributes

In order to implement the pricing calculator functionality, we need to use custom classes and data attributes within Webflow.

Select Classes

The following classes are essential for implementing the pricing calculator:

• hack-44-select: This class needs to be applied to both select input fields. It serves as an identifier for the selects that the JavaScript will target.
• hack-44-added-value: This class will display the total cost calculated based on the user's selections.
• hack-44-send-value: This class is used for a hidden input field that will store the total cost and submit it along with the form.

Data Attributes for Select Options

For each option within the select inputs, we need to assign a value using the data attribute feature in Webflow. These values will be utilized for the total cost calculation.

• Open the options for the select inputs and set the values for each option by utilizing the data attribute feature in Webflow.

By applying the necessary classes and data attributes to the select inputs and their options, we are setting the stage for the JavaScript to perform the total cost calculation based on the user's selections.

Custom Code for Total Cost Calculation

To enable the pricing calculator functionality, we will utilize JavaScript code that interacts with the select inputs and performs the total cost calculation.

// JavaScript for Total Cost Calculationdocument.addEventListener('DOMContentLoaded', function() {  // Target the hack-44-select class and run a function when there is a change in the select field  document.querySelectorAll('.hack-44-select').forEach(select => {    select.addEventListener('change', function() {      // Initialize sum as zero      let sum = 0;      // Iterate through each select input and add its value to the sum      document.querySelectorAll('.hack-44-select').forEach(select => {        sum += parseFloat(select.value) || 0;      });      // Format the sum (optional step for money format)      let formattedSum = new Intl.NumberFormat().format(sum);      // Update the visible total cost display      document.querySelector('.hack-44-added-value').textContent = formattedSum;      // Update the hidden input value for form submission      document.querySelector('.hack-44-send-value').value = formattedSum;    });  });});

Let's break down this JavaScript code step by step:

1. The DOMContentLoaded event listener ensures that the JavaScript is executed once the page has fully loaded.
2. The code targets the select inputs with the class hack-44-select and runs a function when a change occurs.
3. Within the function, a variable sum is initialized to zero to hold the total cost.
4. For each select input, its value is added to the sum.
5. The formattedSum variable formats the total cost using the Intl.NumberFormat function, allowing for comma separation for thousands.
6. The visible total cost display with the class hack-44-added-value is updated with the formatted total cost.
7. The hidden input value for form submission with the class hack-44-send-value is also updated with the formatted total cost.

By incorporating this JavaScript code, the total cost calculation functionality is seamlessly integrated with the select inputs and form submission in Webflow.

Conclusion

In this tutorial, we have demonstrated how to create a pricing calculator with select inputs and a Webflow form. By setting up the select inputs with values and utilizing JavaScript, we have empowered the form to calculate the total cost based on the user's selections. This pricing calculator will enhance user interaction and streamline the process of capturing and submitting total costs through a Webflow form.

With the step-by-step guidance provided, you can now implement a pricing calculator within your own Webflow projects, offering users a seamless and dynamic way to calculate and submit total costs based on their selections.
