Hi all,
Is there a way to explicitly pass in undefined to a function for an
argument?
For example, a function:
<cffunction name="getNumArgs" returntype="boolean">
<cfargument name="a" type="numeric" required="no">
<cfargument name="b" type="numeric" required="no">
<cfargument name="c" type="numeric" required="no">
<cfset numArgs = 0>
<cfif isDefined("ARGUMENTS.a")><cfset numArgs=numArgs+1></cfif>
<cfif isDefined("ARGUMENTS.b")><cfset numArgs=numArgs+1></cfif>
<cfif isDefined("ARGUMENTS.c")><cfset numArgs=numArgs+1></cfif>
<cfreturn numArgs>
</cffunction>
The function call:
I know you can do this:
<cfset result = getNumArgs(a=1,c=1)>
But can you do something like this:
<cfset result = getNumArgs(1,undefined,1)>
Where undefined is replaced with some value? I don't want to have to
rewrite the function to look for a string "undefined" or anything like that.
Thanks!
Nat
