It can be attached to any element, but the event is only sent to the element that has the focus. This is done to ensure that the variable doesn’t contain any pre-existing timeout before assigning a new timeout to it. The keyup event is sent to an element when the user releases a key on the keyboard. Inside the function, the clearTimeout() method is called with the parameter being the variable keyupTimer defined in the first step of the script. We attach a keypress() method to this particular input element with the parameter of the method being an anonymous function. Also, there is a division element that indicates when the keyup with delay effect occurs. Next, there is an input element with an id of “geeks” which accepts any text data. Firstly, a variable keyupTimer with the keyword “ let” is declared such that a timeout can be set with this variable and can be uniquely identified later in the program. There are two ways to achieve the same:Īpproach 1: Using the keypress(), fadeIn(), delay() and fadeOut() methods in the jQuery library and clearTimeout() and setTimeout() methods in native JavaScript.
