javascript - 在 $.each() 函数之外访问 JavaScript 变量

Question

我在将 $.each() 函数中声明的变量传递给 Prototype 函数时遇到问题。我收到错误Uncaught ReferenceError:价格未定义

Compare.prototype.results = function (answers) {

    $.ajax({
        type: 'POST',
        dataType: 'json',
        data: {
            answers: answers
        },

        success: function (data) {

            $.each(data, function (index, dataItem) {

                var prices = [],
                    priceData = dataItem.pricing_term,
                    priceObj = JSON.parse(priceData);

                $.each(priceObj, function (term, pricing) {
                    prices.push(term, pricing);
                });

            });
            Compare.prototype.show(data, prices);
        }

    });
}

我希望能够填充价格变量并将其传递给最初从 ajax 调用返回的数据。我是 javascript 新手，如果有更简洁的方法来编写此内容，请告诉我。

超出范围

Compare.prototype.results = function (answers) {

    $.ajax({
        type: 'POST',
        dataType: 'json',
        data: {
            answers: answers
        },

        success: function (data) {

            var prices = [];


            $.each(data, function (index, dataItem) {
                var priceData = dataItem.pricing_term,
                    priceObj = JSON.parse(priceData);

                $.each(priceObj, function (term, pricing) {
                    prices.push(term, pricing);
                });

            });

            // same scope

            Compare.prototype.show(data, prices);
        }

    });
}
