javascript - 遍历数据并从 csv 文件加载数据

Question

我很难遍历这 2 组数据。使用 1 组数据它可以工作，但现在我想添加更多 3 或 4 。此外，我想从我将上传的本地 csv 文件加载数据并更新数据，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;
    });
});

您必须在文档就绪函数中处理框索引。在您的代码中有一个修复程序“box1”，但 .data 的索引将上升到 7。因此，将索引除以 4，然后您可以计算 box-indexes。您还必须遍历 score-text-elements。

$(document).ready(function() {
   $(".score-text").each(function( index, value ) { 
       value.innerText = data['box'+(index+1)].total;
   });

   $(".data").each(function( index, value ) {  
       var boxIndex = Math.floor(index/4);
       width = data['box'+(boxIndex+1)]['bar'+(index+1-boxIndex*4)];
       value.innerText = width;
       value.style.width = width;
   });
});

我也更新了你的例子。 http://jsfiddle.net/kmc3ohab/11/
