checkbox problems?

[Rabel]

I have a shopping cart that I am having a few problems with. I am
mostly a flash developer with basic if not little javascript knowledge,
I need for my checkout to have a checkbox that if clicked on will
populate my shipping addresses with my billing addresses, I have this
somewhat working with a code I got off of here thats like this

<script>
function copy(checked, source, target) {
if (checked) {
target.value = source.value
} else {
target.value = '';
}
}
</script>
//then like this in the form
<input type=checkbox onClick="copy(this.checked, this.form.bname,
this.form.sname)">

but the problem with that is that I have to put a checkbox with its own
code on each part of the form. I would like to have one that would
then populate the whole form. The other question I have is I need to
have a validate script from the form, the fields are

Name-text
address-text
city-text
state-select
zip-text
country-selected US
Phone-text
email-text

credit card number-text- just need it to check if its numbers and over
12

Any help is greatly appreciated, thanks in advance

I think the problem may be that you didn't actually ask a question. This
isn't a place to get people to write your code for you from scratch, it
is a place to ask questions when you get stuck. Try showing us what you
have tried so far, say what you expected it to do and what it actually
does and then maybe someone will suggest where you are going wrong.

On the face of it you stated that you wanted to do something pretty
obvious so my response would be 'so do it'.

You are an idiot duncan, I did ask a question, and I was only asking
for help I believe I said
'Any HELP is greatly appreciated, thanks in advance'
but you decided that I knew what I was doing and suggested 'so do it'
well thanks man you were a lot of help. Who sits there and complains
about someones question anyway, get a life.

For everyone else out there who may have the same problem this is what
I used to solve it

<script>
function doit(obj,name,address,cityv,statev,zipcode)
{
if(obj.checked)
{
document.frm.elements[name].value = document.frm.bname.value
document.frm.elements[address].value = document.frm.baddr1.value
document.frm.elements[cityv].value = document.frm.bcity.value
document.frm.elements[statev].value = document.frm.bstate.value
document.frm.elements[zipcode].value = document.frm.bzip.value
}
else
{
document.frm.elements[name].value = ""
document.frm.elements[address].value = ""
document.frm.elements[cityv].value = ""
document.frm.elements[statev].value = ""
document.frm.elements[zipcode].value = ""
}
}
function validate()
{
var frm = document.frm

if(frm.bname.value == "" )
{
alert("Please enter valid billing first and last name");
return false;
}
if(frm.sname.value == "" )
{
alert("Please enter valid shipping first and last name");
return false;
}
if(frm.baddr1.value == "" )
{
alert("Please enter valid billing address");
return false;
}
if(frm.saddr1.value == "" )
{
alert("Please enter valid shipping address");
return false;
}
if(frm.bcity.value == "")
{
alert("Please enter valid billing city");
return false;
}
if(frm.scity.value == "")
{
alert("Please enter valid shipping city");
return false;
}
if(isNaN(frm.bzip.value) || (frm.bzip.value.length != 5 ))
{
alert("Please enter a valid zip code");
return false;
}
if(isNaN(frm.szip.value) || (frm.szip.value.length != 5 ))
{
alert("Please enter a valid zip code");
return false;
}
if(isNaN(frm.cardnumber.value) || frm.cardnumber.value.length <13)
{
alert("Please enter valid creditcard number");
return false;
}
if(isNaN(frm.phone.value) || frm.phone.value.length <10)
{
alert("Please enter a valid telephone number");
return false;
}
if(trimit(frm.email.value) != "")
{
return emailTest(frm.email)

}
}
function emailTest(obj){
reg=
/^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
if (!reg.test(obj.value) ){
alert('Invalid email address')
obj.focus()
return false;
}
}

function trimit(strInput)
{
return strInput.replace(/^\s*/,"").replace(/\s*$/,"");

}
</script>
//in the form tag
onsubmit="return validate()
//then on the checkbox
<input type = "checkbox" name = "chk" onclick =
"doit(this,'sname','saddr1','scity','sstate','szip ');">

Hope that helps

That's rather crude validation - it will accept 0xFeedBeef and
0xDeadFade, for example. Similarly for other answers.

Better to test with a RegExp such as /^\d{10,}$/.test(frm.phone.value)
which calls explicitly for 10 or more decimal digits. OTOH, it would be
sensible to permit customary punctuation.

See <URL:http://www.merlyn.demon.co.uk/js-valid.htm>.

Replacing everything like

if(frm.bcity.value == "")
{
alert("Please enter valid billing city");
return false;

with like

if (Bad(frm.bcity, "Please enter valid billing city")
return false;

and a function like

function Bad(C, S) { var B = C.value == ""
if (B) alert(S)
return B }

would make your code more readable, more maintainable, and probably
shorter.
The function in your first article,

function copy(checked, source, target) {
if (checked) {
target.value = source.value
} else {
target.value = '';
}
}

could be written as

function copy(checked, source, target) {
target.value = checked ? source.value : '' }

Code presented for others to read should be indented to show intended
structure.

Your code serves well as an example not to be followed.
