提交第二个下拉框 url javascript

Question

我的 JavaScript 有点生疏了。我有一个下拉菜单，其中包含所有汽车品牌，每个品牌的所有型号都有 URL link 可供选择。

选择品牌后，第二个下拉菜单中会出现一个型号。在 JavaScript 中有 URL link 提交后应该转到所需的 link.

所有代码都在JS里Fiddlelink

好了：

fiddle

HTML

<div class="box">
<p>
    <form name="myform" class="myform" id="myForm">
        <select name="brand" id="select">
            <option value="">CHOOSE YOUR VEHICLE</option>
            <option value="isuzu">Isuzu</option>
            <option value="ford">Ford</option>
            <option value="nissan">Nissan</option>
            <option value="mitsubishi">Mitsubishi</option>
            <option value="toyota">Toyota</option>
            <option value="vw">VW</option>
        </select>
        <button type="submit" id="submit">Search</button>
    </form>
</p>
</div>

JS:

(function($) {

//your model
var urls = {
    isuzu: "https://www.direct4x4.co.uk/catalog/category/view/s/d-max-2012-onwards-canopies-hard-tops-accessories/id/17174/*_blank",
    ford: "https://www.direct4x4.co.uk/catalog/category/view/s/ranger-t6-2012-canopies-hard-tops-onwards/id/17175/*_blank",
    nissan: "",
    mitsubishi: "",
    toyota: "",
    vw: "",
}

//updating the currentUrl
var currentUrl = "";

$("#select").on("change", function(e) {
    var val = $("#select").find('option:selected').attr("value");
    currentUrl = urls[val];
});

$("#myForm").on("submit", function(e) {
    e.preventDefault();
    console.log(currentUrl);
    window.open(currentUrl);

});

}(jQuery));

说明

我主要做的是存储 url 的地图并更新用户 select 的当前 url。

一旦触发提交事件（点击搜索），我就会停止其默认行为并重定向到最后更新的 url（来自 select 'change' 事件'）

只需更新地图中其余的 url，它应该可以完美运行。而且，这样更容易维护。
