How to use function with different form names, and perhaps diff fields

[WestSide2003]

Hi,

I have this function that verifies credit card info....

I wanted to know....how can I use this same function on other pages in the site with different form names and perhaps different field names... right now I will settle for it working with the same field names but different form names.

Some of my pages have more than 1 form so I can't use document.forms[0].fieldName or whatever......

Currently I hardcoded the name of my form and its fields too

so I have statements like if(myformname.CreditCardNumber.value.length == 0) {
alert("Some Error");
}

However, I want to call this function from other pages and I get an error because its looking for the form "myformname", how can I make it more generic.. I am new to JavaScript, so if you respond, please keep that in mind.

Thanks

pass the form and textfield as parameters:
function Hello(TheForm,TheField)
{
alert(TheForm.name)
alert(TheField.value)
}

call it like this:
Hello(document.myformname,document.myformname.CreditCardNumber)

Known is handfull, Unknown is worldfull
