Rayna,
Assuming that all of your checkboxes have the same name, but different
values, this script will work.
function countChecked(TheForm)
{
var cChecked = 0;
for( var i=0;i<TheForm.Item.length;i++ )
{
if( TheForm.Item[i].checked == true )
cChecked++;
}
if( cChecked > 5 )
{
alert('You must choose 5 or less items.');
return false;
}
return true;
}
<FORM NAME="ChoiceForm" ACTION="#Wherever#" METHOD="POST" ONSUBMIT="return
countChecked(this);">
<INPUT TYPE="checkbox" NAME="Item" VALUE="#ItemID#">
... end form
If however you have checkboxes of different names then you would want to
change the function to this (assuming that each item checkbox name had the
same name fragment for instance "Choice1,Choice2,Choice3,...").
function countChecked(TheForm)
{
var cChecked = 0;
for( var i=0;i<TheForm.elements.length;i++ )
{
if( TheForm.elements[i].type = 'checkbox' &&
TheForm.elements[i].name.search(/^Choice/) != -1 &&
TheForm.elements[i].checked == true )
cChecked++;
}
if( cChecked > 5 )
{
alert('You must choose 5 or less items.');
return false;
}
return true;
}
HTH as I'm writing without a page to test the code. It should work
though.... <crosses fingers>

Subject: javascript form help
does anyone know where i can find a script that will limit the user from
chosing more than a certain amount of choices in a checkbox form? the user
can only chose up to 5 choices, but there are many choices that they can
chose from.
any help would be greatly appreciated.
