Sort HTML Tables in a Snap with JavaScript: A 5-Minute Tutorial

In this video, we'll learn how to sort the data in an HTML table using JavaScript and toggle between ascending and normal order. We'll start by getting the reference of the HTML table and its headers. Next, we'll write a function that sorts the data in ascending order when the sort button is clicked and change the button text to "Ascending Order". When the button is clicked again, we'll sort the data in normal order and change the button text back to "Normal". By the end of this video, you'll have a better understanding of how to manipulate HTML tables using JavaScript and toggle between ascending and normal order.

This JavaScript code sorts the data in an HTML table when a sort button is clicked. Here's a step-by-step explanation:

1.Get references to the sort button and the HTML table: The first line gets a reference to the sort button using its id "sortBtn". The second line gets a reference to the table using its id "dataTable".

2.Create a variable for the sort order: A variable named "sortOrder" is created to keep track of the sort order. It is initialized as "asc" for ascending order.

3.Attach a click event to the sort button: The sort button has a click event listener attached to it that calls the "sortTable" function when the button is clicked.

4.Write the sortTable function: The sortTable function takes two arguments, the table and the sort order. It gets the tbody of the table and converts its rows into an array.

5.Write a comparison function: The comparison function is used to compare two rows and determine the order in which they should be sorted. If the sort order is "asc", the function returns the result of subtracting cell2 from cell1. If the sort order is "desc", it returns the result of subtracting cell1 from cell2.

6.Sort the rows: The rows are sorted using the comparison function and the sort method.

7.Remove and append the tbody: The tbody is removed from the table, and the sorted rows are appended back to the tbody. Finally, the tbody is appended back to the table.

8.Update the sort order and button text: If the sort order is "asc", it is changed to "desc" and the button text is updated to "Ascending Order". If the sort order is "desc", it is changed back to "asc" and the button text is updated to "Normal".

This code sorts the first column of the HTML table in ascending or descending order and updates the sort button text accordingly.
