Hi the following code is working in IE, but the focus is not working in Netscpe.
If i am entering a number that is not integer, the cursor should be again in the text field.
But the netscape is not supporting the functionality. Pls help me .

<html>
<head>

</head>
<body>
<form name="myform" action="http://www.mydomain.com/myformhandler.cgi" method="POST">
<input type="text" name="text" maxlength="50" value="12" onblur="validateText(this,'text')">
</form>
</body>
</html>
<script language="JavaScript">
function validateText(form,pro){
var integer = /^\d+$/;
var numb=document.forms[0].text.value;

if(parseInt(numb)!=numb-0) {
alert("Please Enter Integer Only ok")
document.forms[0].text.focus();
}else{
if (window.RegExp &&!integer.test(myform.text.value)) {

Hello ksvijay, welcome to WebmasterWorld.

Generally it's not a good idea to use names like 'text', 'hidden' or 'submit' for form elements, as they may refer to other elements or properties. Maybe that's why Netscape doesn't do what you want.

By the way, you have a regular expression defined that will test for an integer.
You don't seem to be using it.

Change this:

if(parseInt(numb)!=numb-0)

To this:

if(! integer.test(numb) )

Try changing the order of these two statements (after using a new name for 'text').

document.forms[0].text.focus();
alert("Invalid integer value entered (regular expression)");

Any good?

Two remarks:

1. it may be smarter to use onchange() instead of onblur(). My Firefox gets into an endless loop with the combination of onblur() and alert().

2. valid HTML: put the <script> block in the <head> section of your page, or in the <body>, if you prefer.

No solution for the focus()-issue, sorry...
