Form validation - undefined field

[tm]

I am trying to reference a table entry (qtyonhand) populated from a
recordset. There is only one record displayed on this table. When i try to
compare this displayed field to an input field (orderqty) i get an (error on
this page or no result at all ). When just comparing the input field to a
set of "" everything works fine. This is an ASP file with a javascript
function. Thanks in advance.

code below...

<SCRIPT LANGUAGE="JavaS cript" TYPE="text/javascript">
function btnValidate_onc lick()
{
var myform = document.form1;
var qtyonhand = myform.qtyonhan d.value;
alert( myform.orderqty .value + " ");
if(myform.order qty.value=='' || myform.orderqty .value > qtyonhand)

{alert(" Qty ordered is missing or greater than Qty on hand. ");
myform.orderqty .focus();
}
}

You say that qtyonhand is a "table entry".
That's not a very precise description.
Is it a form field?
Maybe you need to show the relevant HTML.

Re: Form validation - undefined field

The field qtyonhand is a form field displayed within the table, sorry
for the confusion.

Relevant HTML.

This seems to be the only occurance of "qtyonhand" .
It's not HTML or Javascript, so I don't know for sure
that it's creating a form element by that name.

Response.Write FormatNumber(rs tINMST("qtyonha nd"),0)
qtyoh = rstINMST("qtyon hand")

To see problems with the javascript, your best bet is to look at the actual
source that the browser sees - the View Source of the browser. NOT the ASP
code you used to generate it.

It's possible that the ASP isn't writing what you expect it to (the fields
aren't there at all).
Post the source from the view source if the following doesn't fix the
problem.

I fixed the following to be more cross-browser instead of using shortcut
syntax. That includes making the variable names different from the names in
the form, JIC. I also used parseInt to make sure the values are used as
numbers, not text. I put in checks for the form fields for your testing
purposes. They can be removed for production.

<SCRIPT LANGUAGE="JavaS cript" TYPE="text/javascript">
function btnValidate_onc lick()
{
if (! document.forms["form1"].elements["qtyonhand"])
{
alert("Form field missing: qtyonhand");
return false;
}

if (! document.forms["form1"].elements["orderqty"])
{
alert("Form field missing: orderqty");
return false;
}

var v_qtyonhand = parseInt(docume nt.forms["form1"].elements
["qtyonhand"].value,10);
var v_orderqty = parseInt(docume nt.forms["form1"].elements
["orderqty"].value,10);

if (isNaN(v_qtyonh and) || isNaN(v_orderqt y))
{
alert("Not a number!");
return false;
}

if(v_orderqty == 0 || v_orderqty > qtyonhand)
{
alert(" Qty ordered is missing or greater than Qty on hand. ");
document.forms["form1"].elements["orderqty"].focus();
}
}
</SCRIPT>

This is untested. Watch for word-wrapping.

Re: Form validation - undefined field

Thanks for cleaning up the code.
The javascript does indicate that the qtyonhand field is missing. I know
i am missing something here.
Got to go thru the learning curve. Thanks for your help.

Yeah, a form field with it in there. ;)

And from looking at it, it should be obvious that the field is indeed
missing. *grins*

So, the error has nothing to do with your javascript.
It's the ASP that's supposed to be generating the field.

Your ASP is generating invalid html. You've got a missing end table cell tag
(very important) and no end form tag (pretty important). I cleaned up the
code, removing style and other stuff I didn't need, to see it properly. What
I saw was an absolute mess.

You've also got some odd spans with nothing in them and stuff (just odd).
You've got style attributes in a font tag (this might be bad).
You need to fix your ASP to make valid html.
Then you need to fix it so it puts the form field where it belongs. It put
the number 3 there instead. ;)

<input name="orderqty" id="orderqty" size="13" maxlength="7">
<TD BGCOLOR="#FFFFC C" ALIGN=middle><d iv align="right">< FONT SIZE=2[color=blue]
>[/color]
3
<STRONG><FONT face="Trebuchet MS"><FONT
style="BACKGROU ND-COLOR:
#ffffff"></FONT></STRONG></FONT></div></TD>

Put the end table cell (</td>) tag after the orderqty input box.
Whatever made this put a 3 in that table cell when I suspect you wanted a
form field, not the value.
If you wanted the value as it is, it still has to be in a form field the way
your script is written. Put it in a hidden form field if you want it not to
display as such.

Looking at your other post, I see this:
<input name="orderqty" id="orderqty" size="13" maxlength="7">
<TD BGCOLOR="#FFFFC C" ALIGN=middle><d iv align="right">< FONT SIZE=2[color=blue]
>[/color]
<%
Response.Write FormatNumber(rs tINMST("qtyonha nd"),0)
qtyoh = rstINMST("qtyon hand")
%>
<STRONG><FONT face="Trebuchet MS"><FONT
style="BACKGROU ND-COLOR:
#ffffff"></FONT></STRONG></FONT></div></TD>

Change that to (no line breaks intended watch for word-wrap):
<input name="orderqty" id="orderqty" size="13" maxlength="7">
</td>
<TD BGCOLOR="#FFFFC C" ALIGN=middle><d iv align="right">< FONT SIZE=2>
<%
v_qtyonhand = FormatNumber(rs tINMST("qtyonha nd"),0)
Response.Write v_qtyonhand
qtyoh = rstINMST("qtyon hand")
%>
<input type="hidden" name="qtyonhand " id="qtyonhand" value="<%
=v_qtyonhand%>" >
<STRONG><FONT face="Trebuchet MS"><FONT style="BACKGROU ND-COLOR:
#ffffff"></FONT></STRONG></FONT></div></TD>

Oh, but ditch the weird font thing while you're at it. Use span for the
background color. This is just too odd looking, even if it does work in IE.
;)
