Time to get anal...
Why do you use the cfoutput? You know that you can do this, right:
<CFSET Foo = ArrayDeleteAt(Session.cart, Itemnum)>
You don't need to do #....#.
You can also do, and this is what I prefer:
<CFSET ArrayDeleteAt(...)>
Or, even better, rewrite the code block in cfscript:
<CFSCRIPT>
for(itemNum=len(session.cart); i gte 1; i = i - 1) {
if(listFind(deleteList, itemArray[itemNum])
arrayDeleteAt(session.cart, itemNum);
}
</CFSCRIPT>
The ArrayResize is not necessary and is only useful for initializing a
large array. The simple act of "ArrayDeleteAt" will change the size.
Of course, the wonderful thing about CF is that there are multiple ways
of doing things, so feel free to ignore me. :)
