ユーザー指定の数値に基づいて入力フォーム要素を動的に作成する方法

<code class="javascript">function addFields(){
    // Get user input for number of elements
    var number = document.getElementById("member").value;

    // Get the element where inputs will be placed
    var container = document.getElementById("container");

    // Remove any existing elements
    while (container.hasChildNodes()) {
        container.removeChild(container.lastChild);
    }

    // Create and append input elements
    for (i=0; i<number; i++){
        container.appendChild(document.createTextNode("Member " + (i+1)));
        var input = document.createElement("input");
        input.type = "text";
        input.name = "member" + i;
        container.appendChild(input);
        container.appendChild(document.createElement("br"));
    }
}</code>
