Answer 1

您可以使用Array.map和Number

let arr = [{ "call_time": "0", "total_inc_traffic": "1363.10", "total_out_traffic": "88.70" }, { "call_time": "1", "total_inc_traffic": "479.57", "total_out_traffic": "36.98" }, { "call_time": "2", "total_inc_traffic": "239.57", "total_out_traffic": "13.43" }, { "call_time": "3", "total_inc_traffic": "190.28", "total_out_traffic": "8.20" }, { "call_time": "4", "total_inc_traffic": "223.80", "total_out_traffic": "0.00" }, { "call_time": "5", "total_inc_traffic": "158.87", "total_out_traffic": "19.58" }];

let result = arr.map(v => Number(v.total_inc_traffic));

console.log(result);
