Code:

document.getElementById(strVal).focus();

Your HTML is invalid (http://validator.w3.org/). It should validate as HTML 4.01 Strict for most applications.

DimX, your code will not work with that markup. The element does not have an ID, so getElementById() should not find it (although it will in IE, another bug).

msg2ajay, the easiest way to do it is to use DimX' code, and give your element an ID. With your existing excuse for markup, you can do:

Code:

document.forms[0].elements[strVal].focus();

... but since your document is so invalid I wouldn't advise it.

The control “empName” has a event “onChange="checkme(this.value)” which passes value of the object. Whereas “focus()” needs object to be focused.
So to focus any object you need to pass it’s object as “onChange="checkme(this);”

May be it will help to you.

<html>
<head>
<script language="JavaScript">

function checkme(strVal){
var id=strVal.id;
alert(id);
//document.all[strVal].focus();---->(IE) FOR IE it is working but not working for mozilla firefox
document.forms[strVal].focus(); //(FIREFOX)
}
</script>
</head>
<body>
<form>
NAME..<input type="text" name="empName" size="5" maxlength="4" onChange="checkme(this)"/><br>
ID....<input type="text" name="id" value=""/><br>
DEPT..<input type="text" name="dept" value=""/><br>
</form>
</body>
</html>
