Question

$("#textbox").one("click", function () {

});

How would I add support for the tab key? If the user on the previous textbox and then clicks the tab key and ends up on #textbox, that’s when the function should be ran, as well as when the user decides to click instead of using the tab key.

Answer 1

You can bind to the focus event instead of the click event:

$("#textbox").one("focus", function () {
    //Do stuff
});

From MDN:

The focus event is used to respond when the focus is given to an
element.

and

The user can change the focus by clicking an element with the mouse or
by pressing the TAB key. When the TAB key is pressed, the next element
is given the focus. To step backwards, the Shift key and Tab key can
be pressed.
