Peter,
What I would like to do is loop through a few records but not the
entire table. Here are my musings on it as I have been trying to get
something to work.
What I am attempting to do is set an optional parameter in the next()
method of the IBO that will accept a numeric value. Then, I var a
variable in the next() method called LimitedRecords. Next I do a check
to see if the argument was passed in and if so I set LimitedRecords to
that number, otherwise I set it to variables.NumberofRecords.
Take a look at this code with my next() function:
<cfargument name="limit" type="numeric" required="false" hint="number
of records to return">
<cfscript>
var ReturnValue = "";
var LimitedRecords = "";
if(structKeyExists(arguments, "limit") AND
len(arguments.limit)){
LimitedRecords = arguments.limit;
}else{
LimitedRecords = variables.NumberofRecords;
}
If (variables.IteratorRecord GTE LimitedRecords)
{
ReturnValue = False;
variables.IteratorRecord = LimitedRecords;
}
Else
{
ReturnValue = True;
variables.IteratorRecord = LimitedRecords + 1;
};
</cfscript>
<cfreturn ReturnValue>
For some reason it does not seem to work. However, I can't really say
if it is working or not because both FF and IE freeze on me when I run
it (the problem I have been having with my implementation of the IBO
has now spread to IE as well).
Thanks,
Aaron
