Filtering Multiple Tables on an HTML Page

When building an HTML page containing multiple tables, you might find it essential to allow users to filter each table's data independently. This means each table should have its own search input, and filtering should only apply to the relevant table. In this guide, I will guide you through the process of achieving this using JavaScript, ensuring your search functionalities are user-friendly and efficient.

The Problem

Imagine you have a webpage with several tables. Below each table, there’s an input box intended for filtering that specific table's content. When attempting to implement the filtering feature, you may find that when you type into any input, all tables are being filtered at once; this isn't the desired outcome. The goal is for each search input to filter only the table that is directly linked to it.

The Solution

To solve this, we will implement a more structured JavaScript function that links specific input fields to their respective tables, enabling independent filtering. Below is a step-by-step process for implementing this solution.

Step 1: Setting Up Your HTML

First, you need to set up an HTML structure with multiple tables and their corresponding input fields. Here's an example:

Step 2: Writing the JavaScript Function

Next, we will create the JavaScript functions to handle the filtering. Here’s the complete code snippet to accomplish that:

Explanation of the Code

filterTable Function: This function accepts a table and a query string. It checks each row's text content against the query using Regular Expressions. If the row does not match the query, it hides the row.

linkInputToTables Function: This function links an input to the desired tables based on the input's associated label. When the user types in the input, it calls the filterTable function on the corresponding table.

Event Listener: We add an event listener for inputs in each label, ensuring that only the relevant table is filtered based on the user's input.

Conclusion

By implementing the JavaScript functions outlined above, you can effectively filter multiple tables on a single HTML page with independent search inputs. This approach not only enhances user experience but also makes your web applications considerably more manageable and interactive.
