循环遍历数据并从csv文件加载数据

我很难遍历这两组数据。有了1组数据，它就可以工作了，但现在我想添加更多的3或4组数据。此外，我想从本地csv文件加载数据，我将上传和更新数据，我将保存文件并覆盖它。http://jsfiddle.net/kmc3ohab/7/

var data = {
    "box1": {
        "bar1": "80%",
        "bar2": "60%",
        "bar3": "40%",
        "bar4": "50%",
        "total": "60%",
    },
     "box2": {
        "bar1": "80%",
        "bar2": "60%",
        "bar3": "40%",
        "bar4": "50%",
        "total": "80%",
    },
};
$(document).ready(function() {
    $(".score-text").html(data.box1.total);
    $(".data").each(function( index, value ) {
        width = eval('data.box1.bar' + (index+1));
        value.innerText = width;
        value.style.width = width;
    });
});
