How to detect Enter key event
At the end of the page add this javascript: function enterPressed(evn) { if (window.event && window.event.keyCode == 13) { alert("IE: Enter is pressed"); } else if (evn && evn.keyCode == 13) { alert("Netscape: Enter is pressed"); } } document.onkeypress = enterPressed; UPDATE Here is modified cross browser version of the code above: function doWhenEnterPressed(evn) { var enterWasPressed = false; if (window.event && window.event.keyCode == 13) { // IE enterWasPressed = true; } else if (evn && (evn.keyCode == 13 || evn.which == 13 )) { // FF enterWasPressed = true; } if (enterWasPressed) { alert('Enter pressed'); // your action code } } document.onkeydown = function(evn) { doWhenEnterPressed(evn); }
