<script src='js/jquery-1.10.2.min.js'></script>
<script>
$(function(){
$('#form1').on('keydown','input',function(e){
e = e || window.event;
var key = e.keyCode || e.which || e.charCode;
if(key == 13){
var inputarray = $('#form1 input');
nextindex = inputarray.index(this)+1;
if (nextindex>=inputarray.length)
{
nextindex=nextindex-1;
}
next = inputarray[nextindex];
next.focus();
}
return false;
});
})
</script>
</head>
<body>
<form action="" name='form1' id='form1' method="post" >
<input type="text" name='user1' value='admin1' /><br/>
<input type="text" name='user2' value='admin2'/><br/>
<input type="text" name='user3' value='admin3'/><br/>
