【问题描述】:
我在循环这两组数据时遇到了困难。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;
});
});

【问题讨论】:
-
您应该避免使用
eval,而是尝试使用array of object,因为您当前的方法限制了您的可能性。 -
如何将其从 eval 更改为对象数组?
-
例如:
var data = { boxes: [{ "bar1": "80%", "bar2": "60%", "bar3": "40%", "bar4": "50%", "total": "60%", },{ "bar1": "80%", "bar2": "60%", "bar3": "40%", "bar4": "50%", "total": "60%", }]}这样您就可以拥有无限数量的盒子,只是不再有唯一的名称。 -
@bash.d 不需要那个 [] 数组。基于文本的索引访问也是可能的。
-
@JosephZammit - 我已经更新了我的答案,向您展示了一种避免 eval 的可能方法。 (记住:eval() == evil)
