How to Extract Values from a Dynamic HTML Table in Node.js Express

If you're working on a Node.js Express project and you have a Dynamic Table in your application where users can add or remove rows and input values into cells, you might find yourself wondering how to extract those values. This guide will walk you through a straightforward solution to retrieve values from your dynamic HTML table and prepare them for MySQL database insertion.

Problem Overview

Dynamic tables are incredibly useful in web applications, allowing users to input and manage data flexibly. However, extracting values from these tables can be challenging, particularly if you're looking for a clean way to organize this data without relying on jQuery. In this post, we'll show you how to capture the values and arrange them into a format ready for database insertion.

Solution Breakdown

Step 1: Modify Your HTML Table

To extract values effectively from your HTML table, you need to make sure that the input fields in the table cells have the same name attribute. This allows you to gather all entries easily into a single array.

Here’s a sample structure of your HTML table:

Step 2: Add Dynamic Rows with Input Fields

Next, we need to implement a JavaScript function to add rows to the table. Each input field will share the same name attribute (cellCargo), which enables us to collect these values later.

Here’s how to implement the addRow function:

Step 3: Extracting Values from the Table

To gather the data from the input fields, we will create a function called documentTableData. This function will iterate through all input fields with the name cellCargo and compile their values into an array.

Step 4: Inserting Data into MySQL

After gathering the data into an array, you can use your preferred method to insert this data into your MySQL database. Typically, you might structure an HTTP request on your backend to handle the incoming data from the front end, enabling seamless data entry into your database.

Conclusion

With these steps, you can efficiently extract values from a dynamic HTML table in your Node.js Express application without relying on jQuery. Using clear attribute names allows you to handle user input seamlessly and prepare it for your database needs.

By following this guide, you will have a robust way of managing user inputs that can adapt to the growing complexity of your forms and data structures. Happy coding!
