Javascript 如何使用国家代码和产品代码制作数组和for循环

我有国家/地区代码和产品代码，根据选择的国家/地区集，与其他国家/地区集相比，该国家/地区集的产品代码将有所不同

共有13个产品代码，它们都是以下下拉列表中的默认值。（405、406、407、408、409、410、411、412、413、414、415、416、417）这些都是美国、加利福尼亚和PH国家的正确产品代码

因此，如果有人从下拉列表中选择了一个产品代码，但不是来自其中一个国家，那么我需要将产品代码下拉列表中的值对应到与指定国家/地区中的相同产品匹配的另一个值

共有4个国家/地区（默认、nfr、eu和jp）

如何使用数组将国家代码存储在节中，例如：

var usca = ["US", "CA", "PH"];
var nfr = ["AU", "BS", "HK", "MX", "NZ", "SG", "TH"];
var eu = ["AT", "BE", "BG", "CY", "CZ", "DK", "EE"];
var jp = "JP";

然后在下面的javascript函数中检索else语句中的值。我不知道如何为此编写for循环

此外，我还需要在第一条else语句下面再粘贴一些else语句，例如：

var usca = ["US", "CA", "PH"];
var nfr = ["AU", "BS", "HK", "MX", "NZ", "SG", "TH"];
var eu = ["AT", "BE", "BG", "CY", "CZ", "DK", "EE"];
var jp = "JP";

在我下面的JavaScript中，代表AU、BS、HK、MX、NZ、SG和TH的国家/地区的产品代码为410，即485。但位于、比利时、保加利亚、塞浦路斯、捷克、丹麦和EE的国家的相同产品代码410为605

这是我的JavaScript函数和选项选择下拉列表

    function getCodes(){
    var countryCode = document.getElementById("country").value;
    var productCode = document.getElementById("products").value;
    var output = document.getElementById("output");
    if ((countryCode == "US") || (countryCode == "CA") || (countryCode == "PH")) {
        output.innerHTML = productCode + " " + countryCode;
    }else{
        if ((countryCode == "AU") || (countryCode == "BS") || (countryCode == "HK") || (countryCode == "MX") || (countryCode == "NZ") || (countryCode == "SG") || (countryCode == "TH") && (productCode == "410")) {
            productCode = "485";
            output.innerHTML = productCode + " " + countryCode;
        }

    }

}

编辑

更新了上面的脚本，将Else If语句合并为@wavemode

您可能需要手动将所有特殊组合输入到一个数组中，并进行如下检查：

/*将所有特殊组合存储在此处*/
变量特殊代码={
AU410:'485'，
BS410:'485'，
HK410:‘485’
/*等*/
};
/*检查用户的组合是否为特殊情况*/
如果（（国家代码+产品代码）在特殊代码中）{
productCode=specialCode[countryCode+productCode]；
}

编辑：您可以使用类似的技术根据国家指定特殊URL。按国家/地区创建具有特殊URL的对象：

/* put special url changes here */
var urls = {
    AU: "urlnrf.com",
    EE: "urleu.com",
    JP: "urljp.com"
    /* etc */
};

if ("US CA PH".indexOf(countryCode) >= 0) { 
    location.href = "url.com?a=" + productCode + "&c=" + countryCode;
}else{
    if ( (countryCode + productCode) in specialCodes) {
        productCode = specialCodes[countryCode + productCode];

        /* url is set to urls[countryCode] if it exists, otherwise "url.com" */
        location.href = (urls[countryCode] || "url.com") + "?a=" + productCode + "&c=" + countryCode;
    }

}

我将实现这一点，并让你知道，如果所有的工作。之后我会重新发布代码。一切正常，但现在的问题是我无法区分4个国家/地区的唯一URL。else语句引用的是specialCodes数组，所有国家代码和产品代码都位于该数组中。例如：默认国家代码有一个唯一的url//url.com/，nfr国家部分AU、BS、HK、MX、NZ、SG和TH使用url//urlnfr.com/，欧盟国家部分位于BE、BG、CY、CZ、DK和EE使用url//urleu.com/，而jp国家部分jp使用url//urljp.com/，就像现在一样，specialCode数组中的所有内容都在使用//urlnfr.com/您能用您要澄清的代码更新您的问题吗？是的，我试图用代码更新它，但它不允许我发布它。它一直在说无效代码，我确保它缩进了4个空格。我会再试一次。我在上面的原始问题中更新了JavaScript代码。谢谢@wavemode你可以把

else{if{

组合成一个简单的

else-if{

谢谢我想知道@wavemode。
