AJAX Tutorials

There are many ways AJAX can enhance user experience, such as adding, editing, or deleting records without reloading the page. With only PHP, deleting records often involves submitting the page or sending values via URL, resulting in page reloads with each deletion.

However, jQuery AJAX offers a more seamless solution. By passing the record ID via AJAX, you can delete records without reloading the page.

A live editable table offers a swift and efficient way to update content directly while viewing it, eliminating the need to navigate to separate edit form pages. This user-friendly feature saves valuable time, as users can modify either specific details or entire records seamlessly within the table itself.

To implement this functionality, use jQuery AJAX, which allows for dynamic and interactive data manipulation. In this guide, we’ll explore two distinct approaches to make table columns editable:

1. Using the contentEditable Attribute:
By adding the contentEditable attribute, you enable quick and in-place editing directly within table cells. This method is perfect for scenarios where rapid updates are preferred, as it removes the necessity for additional input elements.

2. Displaying Input Elements on Cell Click:
The second method provides a structured editing experience. Upon clicking a cell, an input element dynamically appears, pre-populated with the cell’s content. This approach is ideal when you desire a more controlled editing process with standardized input.

By the end of this tutorial, you will have gained valuable insights into creating live editable tables, empowering you to build user-friendly interfaces that optimize productivity and engagement. Let’s dive in and explore the limitless possibilities of jQuery AJAX for crafting exceptional and editable tables.
