Move through the fields below and watch the events that are sent by the browser. For example, use with AT to find out what events are being fired.

  • onfocus, onblur, onclick, ondbclik, onmouseup, onmousedown, onmouseover
  • onkeypress, onkeydown, onkeyup, touchstart, touchend, touchmove, touchcancel

Event types and their target object will be displayed in the section below. Raw event objects will also be logged to the browser console, and may be reviewed with the developer tools.
