Question

In the example code below I have a button that when clicked reloads the page, but hitting enter does not do so, how would one amend it so that hitting enter would also refresh the page?

<h3>click to refresh page</h3>
<input type="button" value="Refresh" onClick="history.go(0)">

You could set a key handler on the page itself if you want to catch any ENTER keypress anywhere:

function catchCR(e) {
  if (!e) {
    e = window.event; // for IE
  }
  var key = 0;
  if (e.keyCode) { key = e.keyCode; } // IE
  if (e.which) { key = e.which; } // FF

  if (key == 13 /* enter key */) {
    history.go(0);
  }
}
if (document.addEventListener) {
  document.addEventListener("keydown", catchCR, true);
} else if (document.attachEvent) {
  document.attachEvent("onkeydown",catchCR);
}
