Question

我在cookie中存储了货币代码。这个值看起来像（EUR，USD，GBP，THB ...）我向免费的API（exchangeratesapi.io）发出AJAX请求，我想在其中将一定数量的THB（泰铢）转换为用户在Cookie中设置的任何货币。

    // Set currency cookie to GBP
    $.cookie("Currency", "GBP");

    // AJAX request to exchangeratesapi
    $.ajax({
        url: "https://api.exchangeratesapi.io/latest?base=THB",
        dataType: 'json'
    })
    .done(function(data) {
        // Set cookie value to var "tocur"
        var tocur = $.cookie("Currency");
        // Get exchange rate for GBP and store it in var "exchangerate" 
        var exchangerate = (data.rates.tocur);
        // Amount of THB to be exchanged to GBP
        var amount = 250;
        // Result for THB amount * exchangerate
        var sum = (amount * exchangerate);
        // Insert result into HTML element, roundet to 2 decimals, replace "." with ","
        $('#responsedata').html(amount + " THB = " + sum.toFixed(2).replace(".", ",") + " " + tocur);
    })
    .fail(function() {
        alert( "Could not fetch exchange rates" );
    });

这很好，只要我将变量“ exchangerate”手动设置为（data.rates.GBP）。尝试将其设置为（data.rates.tocur）时，结果就是NaN。

我想念什么吗？如何获取存储在var“ tocur”中的cookie值以在var exchangerate中工作？我需要以某种方式解析它吗？提前非常感谢您！
