Easily Filter Rows in a Table using jQuery
Filtering data in a table can significantly enhance the user experience by allowing users to quickly sift through large amounts of information and find what they're looking for. Typically, you might encounter jQuery code that filters through list items (<li>), but adjusting this for table rows (<tr>) is straightforward. In this guide, we will guide you through modifying jQuery code to filter rows in a table.
The Basics: jQuery Filter for List Items
Here's a common jQuery snippet used to filter list items:

In this code, we have an input field where users can type their search query. The jQuery on("keyup") method listens for every keystroke, takes the input value, and checks it against the list items. Only matching items are displayed.
Adjusting for Table Rows
To filter rows in a table, you'll need to adapt the logic slightly. Instead of filtering through <li> elements, you will target the <tr> elements.
Here is how you can modify the code to work with table rows:

In this version:
The filterInput remains the same.
The table is identified by its id (myTable). We target the rows inside the <tbody>.
The filtering function still uses the indexOf method combined with toggle, to display only those rows where the cell content matches the search query.
Conclusion
Filtering table rows with jQuery is remarkably similar to filtering list items. By making small modifications to the selector and the context of the filter function, you can transition from list item filtering to table row filtering seamlessly. Implementing this simple, yet powerful feature could greatly improve the usability of your web application, particularly when dealing with large datasets.
We hope this guide has clarified how you can view and manipulate data presented in table form more effectively using jQuery.
