jQuery Event - keyup() Method
Example
Change the text field color when a key is pressed:
$("input").keyup(function(){ $("input").css("background-color","#D6D6FF"); });
Definition and usage
The complete key press process is divided into two parts: the key is pressed, and then the key is released and reset.
The keyup event occurs when a button is released. It occurs on the element currently in focus.
The keyup() method triggers the keyup event, or specifies the function to be executed when a keyup event occurs.
Note:If set on a document element, the event will occur regardless of whether the element is focused or not.
Tip:Please use .which propertyTo determine which key is pressed (Try it yourself)。
