How to Dynamically Display Values from Multiple Input Fields in a Form

When developing web applications, you might encounter scenarios where users need to enter multiple sets of information. For example, imagine a scenario where users can dynamically add multiple address sections for their different office locations. But how do we display all these dynamically entered values for previewing before submission? In this guide, we will explore a solution to this common problem in web development, especially using JavaScript and jQuery.

The Challenge

You have a form that allows users to enter multiple office locations dynamically. While it's easy to display the information from the pre-defined fields, capturing and displaying values from dynamically generated fields can be tricky. The main goals are to:

Allow users to add multiple address fields dynamically.

Collect and display all the entered data including dynamically created sections when the user previews their input.

The Solution

To achieve this, we’ll use jQuery to manage adding new fields and capturing the data. Let’s break down the solution into several key components:

1. Dynamic Input Field Creation

First, we need to set up a way for users to add new address sections dynamically. Here’s how the script can be implemented:

Here, when the "Add Location" button is clicked, new sections for addresses are appended to the form, which allows users to enter multiple addresses.

2. Capturing Data from Input Fields

Next, to display this data when a user clicks on the preview button, you can capture the inputs like this:

In this snippet:

We are using jQuery to select all input fields, mapping their name and value to a string format, and joining them for display.

You could append this string directly to the body or use a modal or designated preview area.

3. Handling Deletions

Users can also remove locations they no longer need. Implementing a simple delete button with the following jQuery will make it seamless:

Conclusion

By structuring dynamic forms using jQuery, we can enhance user experience through easy data entry and validation. The solution shared will allow users to:

Dynamically add and remove address input sections.

Preview all entered values before submission, ensuring accuracy.

Using these techniques, you can effectively manage dynamic input fields in any web application. If you have any questions about this implementation, feel free to leave a comment, and happy coding!
