keydown() Method
Events in jQuery are the actions that the user performs on the web page. It can be anything – related to mouse clicks, keyboard presses, etc. Using jQuery, we can control these events in the order we want and can also attach some custom functions to it if needed. That means, we can use predefined event methods for the actions and also define a function that gets fired when the event method is triggered. Overall, this makes the website more dynamic on the user's end. Let's learn about the keydown() method here.
The keydown() method is a built-in jQuery method. It gets triggered whenever the user presses down any key on the keyboard. Therefore, it executes the attached function, if any, when it detects any key pressed down for the selected element.
Generally, the keydown event is used along with keyup event or keypress event to show some result.
keydown() Method Syntax

$('selector').keydown(function);
It takes one optional parameter – function. The function is the custom function that can be defined to do some tasks when this method gets triggered.
The below example shows how the keydown() method gets triggered when the user starts typing in the given input box.
