如何使用jQuery对这样的JSON数组元素求和:

"taxes": [ { "amount": 25, "currencyCode": "USD", "decimalPlaces": 0,"taxCode": "YRI",
{ "amount": 25, "currencyCode": "USD", "decimalPlaces": 0,"taxCode": "YRI",
{ "amount": 10, "currencyCode": "USD", "decimalPlaces": 0,"taxCode": "YRI",}],

结果应该是:

totalTaxes = 60

    }

    $( "#city" ).autocomplete({
        source: function( request, response ) {
            $.ajax({
                url: "http://airportcode.riobard.com",
                dataType: "jsonp",
                data: {
                    fmt: "JSONP",
                    q: request.term
                },
                success: function( data ) {
                    response( $.map( data.geonames, function( item ) {
                        return {
                            label: item.code + (item.name ? ", " + item.location : "") + ", " + …
