Since you haven't made it clear what we are validating on, you will have to make up your own rule for the highlighted part. Or you could tell me what we are validating on, and I could tell you what to put there:

Code:

<script type="text/javascript">
function val_many(f, n){
for (var e = f.elements, i = e.length - 1; i > -1; --i)
if (e[i].type && e[i].type == 'text' && e[i].name && e[i].name == n && !(e[i].value something)){
alert('Some Message');
e[i].focus();
return false;
}
return true;
}
</script>

Then in the opening tag of your form:

HTML Code:

<form action="whatever" onsubmit="return val_many(this, 'some_name');">

Hi..
Thanks for your kind reply.
I need to validate some conditions .
They are...1.not to be empty field,2.Only numerical,3.Fixed decimal of 4 digits only. These were the validation i have to do.

return val_many(this, 'some_name');">

is it some_name should be text box name or wat?.

Thanks in advance,

I'm not clear on 3:

Fixed decimal of 4 digits only

Would:

1

be OK?

How about:

1.352

?

What would be an example of the smallest number allowed? The largest? Is it that if decimals are used, only 4 places are allowed, or are 4 decimal places required?

To answer your question, yes. You would replace some_name with the name of your text fields.

3. point is to fixed maximum number of 4 digits only e.g: 1234
No fraction s are allowed like 1.234.

Its working fine.i just taken out the

Code:

e[i].focus();

But again i have a small problem.some text boxes are disabled in the same name.
If i filled out correctly for all enabled text box,its being alerting for disabled text box too.HOw i can cure this too.

Here (addition red):

Code:

if (e[i].type && e[i].type == 'text' && e[i].name && e[i].name == n && !e[i].disabled && (e[i].value == ''
|| isNaN(e[i].value - 0) || /\./.test(e[i].value) || e[i].value > 9999)){
