Joshua, thank you for taking the time to answer this ... I tried following
your advice below, but ran into a problem ... got an error when I tried to
put my array in the function call, I get an error cause it's not a string
... let me show you what I've got going ...
On the content page, I have a series of check boxes for item deleltion that
look like this:
<input type="checkbox" name="remove" value=""
onClick="removeSubmit('#cart[ThisOrder].ITEM_ID#');">
This calls the following javascript:
<cfoutput>
<script language="JavaScript">
function removeSubmit(removeVar) {
var removeThis = removeVar
document.removeForm.action = "index.cfm";
document.removeForm.saction.value = "remove_cart";
document.removeForm.CFID.value = "#URL.CFID#";
document.removeForm.CFTOKEN.value = "#URL.CFTOKEN#";
document.removeForm.remove.value = removeVar;
document.removeForm.submit();
}
</script>
</cfoutput>
<form name="removeForm">
<input type="hidden" name="saction">
<input type="hidden" name="CFID">
<input type="hidden" name="CFTOKEN">
<input type="hidden" name="remove">
</form>
On the remove page, I'm trying to do this:
<CFSCRIPT>
function removeItem(remove){
var removeprice = 0;
var i = 1;
for(i=1; i lte arrayLen(cart); i=i+1) {
if (cart[i].ITEM_ID IS url.remove) {
removeprice=cart[i].PRICE;
ArrayDeleteAt(cart, i);
break;
}
}
return cart;
client.subtotal=client.subtotal-request.removeprice;
client.totalitems=client.totalitems-1;
}
</CFSCRIPT>
<cfwddx action="CFML2WDDX"
input="#cart#"
output="client.cartItems"
usetimezoneinfo="No">
The whole thing then passes back to the content page to which redisplays the
updated cart.
So, as I said, for loop doesn't seem to be executing.
I guess I'm having a hard time seeing how I'm going to pass the arguments to
the removeItem() function, when it is a javascript function (to make the
page submit to the remove template) that is actually in the checkbox.
