【问题描述】：

将 forEach 转换为 Forloop 的正确方法是什么。这是我的示例代码。

$.get('/files/foods.txt', function (data) {
    var build = "";
    build += "<tr>";
    build += "<th>Pizza</th>";
    build += "<th>Ice cream</th>";
    build += "</tr>";
    build += "<tr>\n";

    var rows = data.split("\n");
    rows.forEach(function getvalues(thisRow) {
        var foodArray = thisRow.split(",");
        for (var i = 0; i < foodArray.length; i++) {
            build += "<td class=''>" + foodArray[i] + "</td>";
        }
        build += "</tr>\n";
    })

    display.innerHTML = build;
});
