Javascript JSON Stringify清空我的数组

Question

我正在尝试通过stringyfing将数组发送到服务器端，但是操作后结果为空[]。有我的代码：

let calculatePriceOfMultipleFields = (model, field, select, computable) => {
        if(computable.length === 0){
            return false
        }
        let priceArray = fillPriceArray(model, computable)
        console.log(priceArray)
        console.log(JSON.stringify(priceArray))
        let ajaxData = {
            id: select.value,
            model: model,
            field: field,
            priceArray: priceArray
        }
        $.ajax({
            url: "/erp/currencyhandler/multiple-currency-handler/get-price-by-currency",
            data: ajaxData,
            success: function ( data ) {

                console.log(data)
                return false
            }
        })
    }

    let fillPriceArray = (model, computable) => {
        let price = []
        computable.forEach((name) => {
            let id = model.toLowerCase()+"-"+name
            let input = document.getElementById(id)
            price[id] = input.value
        })
        return price
    }

我从console.log得到的是：

[crmorder-amount: "6.22", crmorder-delivery_price: "5", crmorder-discount_percentage: "15", crmorder-total_amount: "10.29"]

在第一个填充数组的位置，第二个简单地为[]。 我的弦乐舞怎么了？我的错在哪里？谢谢！
