Sorting URL Change formatting

[Shannon]

I need to be able to have a GET request as follows:  

http://localhost:8080/api/leads?page=2&size=20&sort=firstName,desc -> or asc

This is for Server Side sorting for a Spring Data Rest project.  Currently the Sorting portion is showing up as an array.  How do you change the way the sorting URL is formed?

Have something that is working now, not sure if this is good or bad.  Any comments more than welcome.

<script>
    function parameterMap(data, operation) {

        if (operation == "read") {

            if (data.sort && data.sort.length > 0) {

                var values = {};
                values["page"] = data.page;
                values["size"] = data.pageSize;
                values["sort"] = data.sort[0]['field'] + ',' + data.sort[0]['dir'];
                return values;

            }

        }

    }
</script>

Found that the above worked for sorting but killed pagination.  Below if the fix for both.

<script>
    function parameterMap(data, operation) {

        if (operation == "read") {

            if (data.sort && data.sort.length > 0) {

                var values = {};
                values["page"] = 1;
                values["size"] = data.pageSize;
                values["sort"] = data.sort[0]['field'] + ',' + data.sort[0]['dir'];
                return values;

            } else {

                var values = {};
                values["page"] = data.page;
                values["size"] = data.pageSize;
                return values;

            }

        }

    }
</script>
