How to sort an array of structs in ColdFusion

Question

I have an array of structs in ColdFusion. I\'d like to sort this array based on one of the attributes in the structs. How can I achieve this? I\'ve found the StructSort fun

Answer 1

Easy solution to sort an array of structures using more than one key using arraySort callback:

It takes array of structs to be sorted as first parameter and array of structs in format of sortkey/sortorder pair as second parameter e.g. [{sortkey: 'FirstName', sortorder: 'asc'}, {sortkey: 'LastName', sortorder: 'desc'}].

    
    
    

    arraySort(
        aOfS,
        function (a, b) {
            for (var i = 1; i lte arrayLen(key_sortOrder); i = i + 1) {
                var prop = key_sortOrder[i];
                var key = prop.key;
                var sortOrder = prop.sortOrder;
                if (a[key] lt b[key]) {
                    if (sortOrder eq 'desc') {
                        return 1;
                    } else {
                        return -1;
                    }
                }
                if (a[key] gt b[key]) {
                    if (sortOrder eq 'desc') {
                        return -1;
                    } else {
                        return 1;
                    }
                }
            }
            return 0;
        }
    );

    return aOfS;

    

Simply call it with:
