JavaScript의 옵션을 사용하여 프로그래밍 방식으로 선택 요소를 채우는 방법은 무엇입니까?

<code class="javascript">var min = 12;
var max = 100;
var select = document.getElementById('mainSelect');

for (var i = min; i <= max; i++){
    var opt = document.createElement('option');
    opt.value = i;
    opt.innerHTML = i;
    select.appendChild(opt);
}</code>

<code class="javascript">function populateSelect(target, min, max){
    if (!target){
        return false;
    }
    else {
        var min = min || 0;
        var max = max || min + 100;

        var select = document.getElementById(target);

        for (var i = min; i <= max; i++){
            var opt = document.createElement('option');
            opt.value = i;
            opt.innerHTML = i;
            select.appendChild(opt);
        }
    }
}</code>

<code class="javascript">HTMLSelectElement.prototype.populate = function (opts) {
    var settings = {};

    settings.min = 0;
    settings.max = settings.min + 100;

    for (var userOpt in opts) {
        if (opts.hasOwnProperty(userOpt)) {
            settings[userOpt] = opts[userOpt];
        }
    }

    for (var i = settings.min; i <= settings.max; i++) {
        this.appendChild(new Option(i, i));
    }
};</code>
