there is a problem between setinterval and this. how to fix it?

Answer 1

Choice of taste:

$("input").keyup(function () {
    setTimeout(() => {
        $(this).next('input').focus()
    }, 2000);
});

$("input").keyup(function () {
    function onTimeOut() {
        $(this).next('input').focus()
    }
    setTimeout(onTimeOut.bind(this), 2000);
});

$("input").keyup(function () {
    const $input = $(this).next('input');
    setTimeout(function () {
        $input.focus()
    }, 2000);
});

$("input").keyup(function () {
    const $input = $(this).next('input');
    setTimeout(function ($elem) {
        $elem.focus()
    }, 2000, $input);
});

And a couple of options for varying degrees of nausea and hipsterism.
PS At the moment, the problem is that you are not passing a function to setTimeout :)
