How to Filter an HTML Table Based on Multiple Keywords Using JavaScript and jQuery

Filtering through data in an HTML table can sometimes feel like a daunting task, especially when you need to display only the rows that match specific keywords. Whether you are developing a web application or handling datasets on a webpage, this guide walks you through an efficient method to achieve this using JavaScript and jQuery.

The Problem Statement

Imagine you have an HTML table that lists various items, complete with an ID, name, and associated tags. You want to filter this table so that only rows containing all specified keywords are shown. For instance, if you want to filter for the keywords "HIGHER EDUCATION" and "RENOVATION", the output should only include rows that contain both terms, even if there are additional unrelated terms in the tags.

Example Table Structure

Your HTML table might look like this:

The Solution

To filter your HTML table effectively, we will utilize jQuery to create a simple filter mechanism. The process involves setting a filter attribute to buttons that will initiate the filtering of table rows based on keywords provided. Here’s how you can implement this in a few steps.

Step 1: Create Filter Buttons

First, you will need to create filter buttons. Each button will have a filter attribute containing a comma-separated list of keywords.

Step 2: Handle Click Events on the Filter Buttons

Next, you will attach an event listener to these buttons using jQuery. When a button is clicked, it will retrieve the keywords from the filter attribute, split them into an array, and filter the table rows accordingly.

Step 3: Reset Functionality

It’s also important to allow users to reset the filters and show all table rows again. This can be achieved with a button that has an empty filter attribute.
