如何将整数转换为罗马数字？

function romanNumeralGenerator (int) {

}

例如,请参阅以下示例输入和输出:

1 = "I"
5 = "V"
10 = "X"
20 = "XX"
3999 = "MMMCMXCIX"

警告:仅支持1到3999之间的数字

我正在尝试存档的是克隆我的"盒子"并拥有一个没有值的克隆.所以输入应该是空的.我有这个小提琴,只有函数和HTML.希望很清楚,你们可以帮助我.

addAddress: function() {
    var cloneCount = 0;
    $copy = $("#scroll .first").first().clone().attr("id", "to-add-first_Clone" + cloneCount).addClass('cloned'); //add a new class cloned to the cloned outerDivs
    $(".clone", "#to-add-first_Clone" + cloneCount).attr("id", "clone_Clone" + cloneCount);
    cloneCount++;
    //check breakpoints
    var $last_bp = $('#scroll .wrap .breakpoint').last();
    var $first = $(".first", $last_bp).length;
    if ($first > 2) {
        //move this into a new breakpoint
        $('#scroll .wrap').append('<div class="breakpoint"/>');
        $last_bp = $('#scroll .wrap .breakpoint').last();
    }
    $last_bp.append($copy);
    this.drawNavigation();
},

我有4个选项,我希望能够选择多个选项或通过第二次单击删除所选类.

jQuery的

$('.contact-method li a').click(function(e) {
        $('.contact-method li a').removeClass('selected');
        $(this).parent('a').addClass('selected');
        e.preventDefault();
});

HTML

<ul class="contact-method">
<li class="sms"><a href="javascript:void(0);">SMS</a></li>
<li class="telephone"><a href="javascript:void(0);">Telephone</a></li>
<li class="email"><a href="javascript:void(0);">Email</a></li>
<li class="post"><a href="javascript:void(0);">Post</a></li>
</ul>
