I’ve wrote a simple JavaScript function in the <head> tag of the page to validate a form in that page, and it worked well. Then I wrote another function in the same <head> to validate another form, the second function worked but the first stopped working! I deleted the second function but the first stopped working permanently and I don’t know why. The code is listed below
The first function
[CODE]function validate_addproduct_form()
{
c = /^d{1,}$/;
p = /^d{1,}.{0,1}d{0,2}/;
string = ”;
if (!c.test(addproduct.code.value))
{
string += ‘n* The code you entered is not a valid code.’;
}
if (!p.test(addproduct.price.value))
{
string += ‘n* The price you entered is not a valid price.’;
}
if (string != ”)
{
alert (‘The following error(s) occured:n’+string+’nnPlease correct the errors and try again.’);
event.returnValue = false;
}
else if (addproduct.description.value == ”)
{
action = confirm(“You haven’t inserted description. Do you want to continue?”);
if (action == false)
{
event.returnValue = false;
}
}
}
Which validates this form
[CODE]<form name=”addproduct” enctype=”multipart/form-data” method=”post” action=”index.php” onsubmit=”validate_addproduct_form();”>
<table align=”center” width=”80%” border=”0″ cellpadding=”5″ cellspacing=”0″ style=”border-collapse: collapse” id=”AutoNumber1″>

<input type=”hidden” name=”action” value=”add”></td>
<td align=”center”><BR>
<input type=”submit” value=”Add Product” name=”submit”></td>
</tr>
</table>
</form>
The second function
[CODE]function validate_login_form()
{
if (login.user_name.value == ” || login.password.value == ”)
{
alert(‘Please insert the missing fields’);
event.returnValue = false;
}
}
Which validaes this form
[CODE]<form name=”login” method=”post” action=”index.php” onsubmit=”validate_login_form();”>
