How to Retrieve Edited Data from an HTML Table in Angular 2

In the world of web development, tables are an essential element for displaying data. However, making the data editable can introduce complexity, especially when you need to gather the updated information upon a user's action, like clicking an update button. In this guide, we'll tackle a common requirement in Angular 2 applications: how to retrieve edited data from an HTML table and send it back to your database efficiently.

The Problem

Imagine you have an Angular 2 application with a table showcasing data fetched from a database. Your goal is to allow users to edit specific cells in the table and then save those changes upon clicking an "Update" button. The issue arises when you need to fetch the edited values along with the associated row ID. You might have initially tried using a contenteditable attribute on the table cells, but this approach will not help in capturing the edited values effectively.

The Solution

Step 1: Using Input Elements

Instead of relying solely on the content editable property of table cells, we can enhance our solution by incorporating input elements into the table. By doing so, we can easily capture user input. Below is a revised code snippet to achieve this:

Step 2: Key Changes Explained

Input Elements: Replace the contenteditable attribute with <input type="text">. This enables the two-way data binding feature in Angular, allowing you to retrieve values more efficiently.

Template References: Use the # data1 and # data2 template reference variables to reference the input elements for editableData1 and editableData2.

'updatetoDB' Method: Modify the button's click event to pass the values of data1 and data2 directly to the updatetoDB function along with the row ID. This function can now access the state of the input fields when the button is clicked.

Step 3: Updating the Data in the Database

In your component's TypeScript file, implement the updatetoDB method to handle the data update logic:

Conclusion

By integrating input elements into your HTML table, you can effortlessly capture edited values alongside their respective IDs upon user interaction. This approach not only simplifies the data retrieval process, but also enhances the user experience by providing a clear and intuitive interface. With this method, you'll ensure that your Angular 2 application handles data updates smoothly and efficiently.

Now go ahead and give it a try in your Angular application, and enjoy the seamless editing of table data!
