• php
• javascript
• jquery
• html

• You need to use the Event interface (first parameter or window.event). – Marcel Korpel Commented Mar 7, 2013 at 11:57
• This could be acplished without it being inline. – Jeff Shaver Commented Mar 7, 2013 at 12:07

If you want to use inline js, just put event.keycode instead of keycode you can use:

<input type="text" id="tt" name="tt" onkeydown="javascript: if(event.keyCode == 13) alert(1);"/>

why inline?? when you can call event in jquery

try this

$('#tt').keydown(function(e){
    if (e.keyCode == 13) 
    {
      alert(1);
    }
}

and if incase you need inline... you need to call event.keyCode to get the keycode of key pressed

 <input..name="tt" onkeydown="yourFuncName(event)"....>

 function yourFuncName(e){
     if (e.keyCode == 13) 
     {
        alert(1);
    }
 }

<input type="text" id="tt" name="tt" onkeydown="myFunction(event)"/>

<script type="text/javascript">
    function myFunction(e) {
        if (e.which === 13 || e.charCode === 13 || e.keyCode === 13)
            alert(1);
    }
</script>

Please not that not all browsers support keyCode. Some use which and others use charCode.
