You said components above - although we are talking about script based
udfs. For a CFFUNCTION type UDF or METHOD, any <CFARGUMENT> tag w/o a
required setting will default to NOT being required. In a script based
udf, any argument declared is required. For example:
function add(x,y) {
return x+y;
}
In this UDF, both x and y are required because they are declared. To use
optional arguments, you simply check the size of the arguments array.
function addMore(x,y) {
var c = 0;
if(arrayLen(arguments) gte 3) c = arguments[3];
return x+y+c;
}
Or even
function addALotOfCrap() {
var total = 0;
var i = 1;
for(;i lte arrayLen(arguments);i=i+1) {
total = total + arguments[i];
}
return total;
}
Or even better, if you trust all arguments are numeric: return
arraySum(arguments);
Anyway, you get the idea. For more examples of UDFs, check out
