How can I detect shift + key down in JavaScript?

Javascript Solutions

Solution 1 - Javascript

event.shiftKey is a boolean. true if the Shift key is being pressed, false if not. altKey and ctrlKey work the same way.

So basically you just need to detect the keydown as normal with onkeydown, and check those properties as needed.

Solution 2 - Javascript

var onkeydown = (function (ev) {
  var key;
  var isShift;
  if (window.event) {
    key = window.event.keyCode;
    isShift = !!window.event.shiftKey; // typecast to boolean
  } else {
    key = ev.which;
    isShift = !!ev.shiftKey;
  }
  if ( isShift ) {
    switch (key) {
      case 16: // ignore shift key
        break;
      default:
        alert(key);
        // do stuff here?
        break;
    }
  }
});
