 Javascript
Guys help me in identifying the errors in the following code and hence writing the code that validate form
<html>
<head>
<meta http-equiv="Content-Language" content="en-us">
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">

function validate()
{
var fname = document.getElementById("fname").value
var lname = document.getElementById("lname").value

var address = document.getElementById("address").value
var cellNumber = document.getElementById("cell").value
var regExp = (/[A-Za-z0-9]+\@[A-Za-z0-9]+(\.[A-Za-z0-9])*\.[A-Za-z]/)
var email = document.getElementById("email").value
var reg= (/[A-Za-z]\*/)
var c = (/[0-9]*/)
submitOK = "true"
if(fname <reg)
{
alert("Enter a valid first name")
submitOK = "false"
}
else if(lname<reg)
{
alert("Enter a valid surname")
submitOK = "false"
}
else if (omang.length!=9||isNaN(omang))
{
alert ("Please enter a valid ID Number")
submitOK = "false"
}
else if(chief<reg)
{
alert("Enter a valid Chief's name")
submitOK = "false"
}
else if(address<reg)
{
alert("Enter a valid Address")
submitOK = "false"
}
else if(cellNumber<c && cellNumber.length!=8)
{

}

return false

}

As far as the validation goes, you never return true, so the form probably won't submit. You also don't need to getElementById for all those, but it's not wrong to do so.
There is nothing to fear, but life itself.

I did not use return true for validating, I only used return true in the confirmation msg, that is if the user enters information into the form and then by mistake he clicks reset confirmation msg will pop up, asking him whether he want to reset or not, and if he clicks ok it will return true (a fresh form) and if he clicks cancel nothing will happen..........
The following is the code....... and it is working well
<script>
function Confirm()
{
var agree = confirm ("Are you sure you want to resert");
if (agree)
{
return true
}
else{
return false
}
}
</script>
<input type="reset" value="Reset" name="B2" onclick="return Confirm()">

But you have to return true on the validation function somewhere, or the form will never submit. That's not the validation function.

Omang in Botswana means ID Number, so the field is going to capture on a nine digits number, and currently I have set the First Name fields to accept only lower case alphabets....
Thanx guys en enjoy JS
