有什么想法或建议吗？谢谢。

试试这个：

JQuery：

标记：

这只是一个基本示例，但它将生成所需的HTML

jsIDLE:

FYI，TypeList是一个值为数组的对象。@Andy好的，但如何生成我正在谈论的输出。谢谢您的帮助，但您在选项中显示的数字是不可能的。我无法使用循环显示数字。啊，很抱歉，没有注意到您需要递增的数字。让我来换一下。@Manan，现在检查一下。

var TypeList = {
    'One': ["Any", "Abigail", "Adam", "Jake", "Michael"],
    'Two': ["Any", "Gavin", "Amanda", "Donna", "Irene"],
    'Three': ["Any", "Sarah", "Nicholas", "Ellison", "Cornish", "Neil"],
    'Four': ["Any", "Rebecca", "Sophie", "Yvonne", "William", "Hill"]
}; 

var counter = 1;
addFromArray(TypeList.One, "one");
addFromArray(TypeList.Two, "two");
addFromArray(TypeList.Three, "three");
addFromArray(TypeList.Four, "four");


function addFromArray(arrayItems, dropdown)
{
    for(var i = 0; i < arrayItems.length; i++)
    {
        $("#" + dropdown).append("<option value='" + (i===0?"Any":counter) + "'>" + arrayItems[i] + "</option>");
        if (i!==0)
            counter++;
    }
}

<select id="one"></select>
<select id="two"></select>
<select id="three"></select>
<select id="four"></select>
