Creating an Editable HTML Table

In this tutorial, we will learn how to create an editable HTML table using plain JavaScript. We will not be using any libraries or jQuery for this. The table will allow users to click on individual cells and edit the information inside them. We will also add styling to the table to make it visually appealing. So let's get started!

2. Creating an Editable HTML Table

To create an editable HTML table, we will first need to create the HTML structure for our table. This can be a basic table with some data or you can customize it to your taste. Once we have the table structure, we can proceed with adding the necessary JavaScript code.

3. Styling the Table

You can add different styles to your table to make it visually appealing. This will depend on your personal preference and the overall design of your website. You can set the background color, font family, font size, and text alignment of the table cells to match your desired style.

4. Obtaining Table Cells

To make the table cells editable, we need to obtain all the cells from our table using JavaScript. We can do this by using the getElementByTagName() method and passing it the argument "td". This will return an HTML collection of all the table cells.

5. Adding Event Listener to Cells

Once we have obtained the table cells, we can add an event listener to each cell using a for loop. This will allow us to trigger a function when a cell is clicked. In this function, we will replace the text inside the cell with an input element so that it can be edited.

6. Replacing Text with Input Element

When a cell is clicked, we will replace the text inside the cell with an input element. This will allow the user to edit the content of the cell. We will create the input element dynamically using the createElement() method and set its attributes such as type and value. We will then style the input element to match the size and appearance of the cell.

7. Styling the Input Element

To style the input element, we can set its width and height to match the dimensions of the cell. We can use the offsetWidth and offsetHeight properties to obtain the width and height of the cell. We will also set the font family, font size, text alignment, and background color of the input element to match the cell.

8. Handling Cell Focus and Blur

When a cell is clicked, it becomes selected and the input element is displayed. We need to handle the focus and blur events of the input element to ensure that it behaves correctly. When the focus is lost, we will check if there are any changes in the text. If there are changes, we can save the new data to a database using Ajax.

9. Checking for Changes in Text

To check if there are any changes in the text of a cell, we can compare the original text with the current text entered by the user. If there are differences, we can save the new data to a database. We will remove the custom attributes that we added to the cell and replace the input element with the new text.

10. Saving Data to Database

In this section, we can save the new data entered by the user to a database using Ajax. We can make an Ajax request to the server with the updated data and update the database accordingly. However, this tutorial does not cover the server-side implementation. You can add your own code to save the data to the database.

And that's it! You have successfully created an editable HTML table using JavaScript. Now users can click on the cells, edit the content, and save the changes. Feel free to customize the table further or add additional functionality as per your requirements.
