如图  ## 代码 这里主要用到了`push` ``` var paylist = [ {"id":"1","paymode": '1', "payname": "现金", "paymoney": "20"} , {"id":"3","paymode": '2', "payname": "支付宝", "paymoney": "50"} , {"id":"2","paymode": '1', "payname": "现金", "paymoney": "40"} ]; var newPaylist = []; for (var i = 0; i < paylist.length; i++) { newPaylist.push(paylist[i]); } ```
