Using JavaScript you can do check working jsfiddle



document.onkeydown = function(evt) {

    evt = evt || window.event;

    if (evt.keyCode == 27) {

        alert('Esc key pressed.');

    }

};

Using jQuery you can do check working jsfiddle



jQuery(document).on('keyup',function(evt) {

    if (evt.keyCode == 27) {

       alert('Esc key pressed.');

    }

});

check for keyCode && which & keyup || keydown



$(document).keydown(function(e){

   var code = e.keyCode || e.which;

   alert(code);

});

Note: keyCode is becoming deprecated, use key instead.



function keyPress (e) {

    if(e.key === "Escape") {

        // write your logic here.

    }

}
