jqueryHow do I use the jQuery keyup enter event?

The jQuery keyup() event is used to detect when a key is released on the keyboard. The enter key is commonly used to submit forms or trigger a search. To use the keyup() event with the enter key, you can use the following code:

$('input').keyup(function(e) {
    if (e.keyCode == 13) {
        // Do something when enter is pressed
    }
});

The keyup() event takes a function as a parameter which will be called when a key is released. Inside the function, the keyCode of the key that was released is checked. If the keyCode is 13, then the enter key was pressed.

The following are the parts of the code:

1. $('input').keyup(function(e) - This part of the code attaches the keyup() event to all <input> elements. The event will call the function passed to it whenever a key is released.

2. if (e.keyCode == 13) - This part of the code checks if the keyCode of the key that was released is 13. If it is, then the enter key was pressed.

3. // Do something when enter is pressed - This part of the code will be executed if the enter key was pressed.
