Clearing checkboxes

I have a form that contains several radio buttons and checkboxes that correspond with the radios.

For instance:

(radio) Supreme Pizza
<checkbox> no onions <checkbox> no sausage <checkbox> no cheese ....
(radio) Meat Lovers Pizza
<checkbox> no sausage <checkbox> no canadian bacon...

and so on.

You select Supreme Pizza initially and select the "no onions" chechbox.

But then you change your mind and click the MeatLovers. The radio button is reset correctly but how can I automatically clear the "no onions" checkbox from the Supreme Pizza?

Thanks for you help.

basically you are going to have to make a function to clear all of the resets for all check boxes on the page when they click the button.

document.FormName.checkboxname.checked=false;

basically you can make a look and look through each one

document.FormName[checkboxNameVariable].checked = false;

Need more help just give a hollar...

Thanks Eric,

I thought I could figure it out but I'm stumped (and new to script)

here is some code -i'm sure its something simple.

As I understand it - when you click on the radio button (named "item") it runs the ClearCheckBoxes fuction - which should set all checkboxes (check1, check2 ...) to off.

Why isn't it working?

NOTE - i cut a lot of table formatting stuff out so you wouldn't have to sift through it.

Thanks

your form name is order

An easier way to do it would be

See if that helps you out.

I think I'm close but I keep getting an error "document.order.a'is null ornot an object". What am I doing wrong?

<SCRIPT>
var a = new Array(17);
a[0]="Supremeonion";
a[1]="Supremebellpepper";
a[2]="Suprememushrooms";
a[3]="Supremepepperoni";
a[4]="Supremeitaliansausage";
a[5]="Veggiemaxonion";
a[6]="Veggiemaxbellpepper";
a[7]="Veggiemaxmushrooms";
a[8]="ClassicPepperonipepperoni";
a[9]="Prosciutto&Arugulaprosciutto";
a[10]="Prosciutto&Arugulaarugula";
a[11]="AmericanClassicpepperoni";
a[12]="AmericanClassicItalianSausage";
a[13]=A"mericanClassicbellPepper";
a[14]="Eggplant&Garliceggplant";
a[15]="Eggplant&Garlicgarlic";
a[16]="BBQChickenBBQChicken";

function ClearCheckBoxes() {
for(var yy = 0;yy < a.length; yy++){
document.order.a[yy].checked=false;
}
}
</SCRIPT>
 
 
<H2><Center>Menu</Center></H2>
 
<FORM ACTION=confirm.jsp NAME=order>
<TABLE>
<TR><TD>
<TABLE>
 
<TR>
<TD><INPUT TYPE=RADIO NAME="item" OnKlick="ClearCheckBoxes();" VALUE="Supreme" ><B>Supreme </B></TD>
</TR>
 
<TR>
<TD>

<TABLE>
<TR>

 
<TD><INPUT TYPE=CHECKBOX NAME=Supremeonion>86 onion</TD>

add quotes around all of the words in your array a[X]="blah";

also change this
document.order.a[yy].checked=false;
to
document.order[a[yy]].checked=false;

Excellent!!!

Thanks!!!

Halleluia!!
