Let us now see an example illustrating the order of events keydown() and keyup(). In the above example, we saw that as soon as the key is released, the keyup event is triggered which in turn executes the attached function that changes the background color.

Background color changes to yellow once this button is clicked.

The reset button is clicked to try entering the value again in the text box.

This function on execution changes the background color to coral.

The keyup event occurs once a key is released, which in turn makes the keyup() method to execute the attached function.

The reason behind this color change is that the jQuery keyup() method attaches a function to the selected input box as soon as the keyup event is triggered on releasing the key.

Now, as we press any key and release it, the background color of the input box changes to coral as shown in the screenshot below.

At this point, the background color of the text field is white with no input provided.
