I am trying to execute some code of js when user press key "enter" or "tab". When I alert keycode then showing correct, but when press key "enter or tab" then not showing any response. I tried following code.

<input id="to" onkeypress="checkemail(event);">

function checkemail(evt)
{
    var keycode =  evt.keyCode? evt.keyCode : evt.charCode;
    //alert(keycode);
    if(keycode=='13'|| keycode=='9')
    {
          //MyCode
        }

}

This code is work properly in FireFox, but not showing any result in Google Chrome. Please tell me any solution if have. Thanks in advance.

  • 2 Use keyup instead of keypress, keypress is not guaranteed to fire for all keys. – Esailija Commented Jul 23, 2012 at 14:34

Reset to default 2 
<html>

<body>

<input type = "text" id = "to" onkeydown="check(event)">

<script type = text/javascript>

function check(evt)
{
var keycode = evt.keyCode;
alert(keycode);
}

</script>

</body>

</html>

it works in chrome :)

I remend using jquery's keydown. it will deal with cross browser issues like this for you

function checkemail(evt)
{
    var evt=evt||window.event;
    alert(evt.keyCode);
    if(evt.keyCode==13||evt.keyCode==9)
    {
        //your code
    }
}

I thought my use of keycode in Chrome wasn't working, but it actually does. I used the enter key to trigger opening a new tab in Chrome. With recent Chrome updates, the pop-up blocker prevented me from redirecting in a new tab. The target="_blank" wasn't working & had nothing to do with my condition, event.keycode == 13.

It works in chrome you need to type event.keycode/event.key instead of evt.keycode/evt.keycode.also key press doesn't works for these keys you are using
