jquery get td with class active in javascript

To get the td element with class active using jQuery, you can use the .find() and .filter() methods.

Assuming your td elements are part of a table with id myTable, you can use the following code:

index.tsx
// Select the table and find all td elements with class 'active'
var activeTds = $('#myTable').find('td.active');

// Use the filter() method to get the td element with the 'active' class
var activeTd = activeTds.filter(function() {
    return $(this).hasClass('active');
});

// Now you can access the properties of the active td element
activeTd.css('color', 'red');

In the above example, activeTds will contain all td elements with class active that are descendants of the table with id myTable. We then use the .filter() method to select the td element with the active class, assigning it to the activeTd variable. Finally, we can access any of the td element's properties, in this case changing its text color to red using the .css() method.
