The speed of the fading effects of fadeIn() and fadeOut() are both specified as вЂњfastвЂќ. The setTimeout() method has an anonymous function as its parameter which changes the opacity of the division element from hidden to visible using the fadeIn() method and after some delay again changes the opacity of the division element, this time from visible to hidden using the fadeOut() method. Thereafter, a new timeout is created with the setTimeout() method to add the delay after the keypress() function which generates the desired effect i.e. If the code of the key pressed code is 13 then the ENTER key was pressed Otherwise some other key. This is done to ensure that the variable doesnвЂ™t contain any pre-existing timeout before assigning a new timeout to it. LetвЂ™s see an example 2 with demonstrate jQuery keypress () as shown below: To check whether the user has pressed the ENTER key on the webpage or on an input element, you can tie a keyup or keydown event to that element or document object. 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 вЂњgeeksвЂќ which accepts any text data. Firstly, a variable keyupTimer with the keyword вЂњ letвЂќ 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:ДЄpproach 1: Using the keypress(), fadeIn(), delay() and fadeOut() methods in the jQuery library and clearTimeout() and setTimeout() methods in native JavaScript.
