I know it is me but i can not get this condition to work. Regardless of
Check or credit card it always defaults to else portion of the script.
I can't get if (login.PMT_INDICATOR.value == "C") to be true. What i am
doing wrong? please help







<html>

<form method="post" name="login" id="login" >
<input type="hidden" Value ="Account Balance"
name="PMT_TYPE_DESC" >
<input type="radio" Value ="" name="PMT_INDICATOR"> Check
(Checking/Saving Account)<p>
] <input type="radio" Value ="C" checked name="PMT_INDICATOR" >
Credit Cards</p><p>
<input type=button name=submit1 value="Login"
Onclick="SubmitForm(login);">
</p>
</form>

<script type="text/javascript">
<!--

function SubmitForm(login)
{

if (login.PMT_INDICATOR.value == "C")
{
login.action = "https://creditcard.gateway.com/Gateway.aspx";
}
else
{
login.action = "https://Check.gateway.com/Gateway.aspx";
}
login.submit(); // Submit the page
return true;

Use:

document.login.PMT_INDICATOR.value

Or:

document.forms['login'].elements['PMT_INDICATOR'].value

OTOH, you could fix it by changing the call to submitForm into:

<input type=button name=submit1 value="Login"
Onclick="SubmitForm(this.form);">

If an expression that you think should be true, isn't, add an alert()
to show you what the value really is.
In this case:

alert(login.PMT_INDICATOR.value)

will show you that the value is never "C".

same. I tried that before. It is not that. Any other idea.

Lee,
When i did that it tells me PMT_INDICATOR is undefined. It tried this
but did not work either.



<form id="login" name="login" method="post"><input type="hidden"
value="Account Balance" name="PMT_TYPE_DESC"><input type="radio"
value="" name="PMT_INDICATOR"> Check (Checking/Saving Account)

<p>] <input type="radio" checked value="C" name="PMT_INDICATOR"> Credit
Cards</p>

<p><input onclick="SubmitForm(this.form, login.PMT_INDICATOR.value);"
type="button" value="Login" name="submit1"></p>
</form>
<script type="text/javascript">
<!--

function SubmitForm(login, PMT_INDICATOR)
{
var pmt = PMT_INDICATOR
if (pmt == "C")
{
alert(pmt)
login.action = "https://creditcard.gateway.com/Gateway.aspx";
}
else
{
alert(pmt)
login.action = "https://Check.gateway.com/Gateway.aspx";
}
login.submit(); // Submit the page
return true;
}

//-->
</script>

<input type="radio" value="" name="PMT_INDICATOR"> Check
(Checking/Saving Account)
<input type="radio" checked value="C" name="PMT_INDICATOR"> Credit
Cards

After taking this a part, it turns out the problem is with two check
boxes with same name. is there any way to get around this problem?

thanks

I don't even see one checkbox, much less two.

Yes, but you have many more problems than just that.
Try this, which includes several fixes [untested]:

<form id="login" name="login" method="post"
action="https://Check.gateway.com/Gateway.aspx"
onsubmit="return checkform(this)">
<input type="hidden" value="Account Balance" name="PMT_TYPE_DESC">
<input type="radio" value="" name="PMT_INDICATOR"> Check (Checking/Saving
Account)
<input type="radio" checked value="C" name="PMT_INDICATOR"> Credit Cards
<input type="submit" onclick="SubmitForm(this.form,
login.PMT_INDICATOR.value);" type="button" value="Login" name="submit1">
</form>

<script type="text/javascript">
function checkform(f) {
if (f.PMT_INDICATOR[0].checked) {
f.action = "https://creditcard.gateway.com/Gateway.aspx";
}
return true;
}
</script>

But, as a general rule, changing the action attribute of a form points to
bad design. If script is disabled, for example, your form breaks. Business
logic should be done on the server side.

As a final suggestion, see
