javascript - 将数组值转换为对象键

Question

我做了一个 get，它返回一个 json 对象，如下所示:

"data": [
  [
    "2016 Pass/Fail Rates by Test Centre",
    "",
    "",
    "",
    "",
    "",
    "",
    "",
    "",
    ""
  ],
  [
    "",
    "Passes",
    "",
    "No ID",
    "",
    "Fails",
    "",
    "Fail Dangerous",
    "",
    "Total"
  ],
  [
    "Sometown",
    "8,725",
    "53.40%",
    "140",
    "0.90%",
    "7,417",
    "45.40%",
    "48",
    "0.30%",
    "16,330"
  ],
  [
    "Some Other Town",
    "12,778",
    "44.80%",
    "193",
    "0.70%",
    "15,422",
    "54.10%",
    "103",
    "0.40%",
    "28,496"
  ],
  [...many more identically formatted arrays...]

最后我想:

[{
    "Location": "Sometown",
    "Passes": 8,
    725,
    "Pass%": 53.40 % ,
    "No ID": 140,
    "NoID%": 0.90 % ,
    "Fails": 7,
    417,
    "Fail%": 45.40 % ,
    "Fail Dangerous": 48,
    "FailDangerous%": 0.30 % ,
    "Total": 16,
    330
  }, {
    "Location": "Some Other Town",
    "Passes": 8,
    725,
    etc etc...

所以我想忽略“数据”数组中的第一个数组，使用第二个数组的值作为键(并用更有用的东西替换空字符串)，并将所有剩余数组中的值作为结果中的值对象。

所以这是一个多部分问题，尽管我怀疑这是一个相当简单的问题。最简单的方法是什么 - 如果不同，在处理/页面加载方面最精简的方法是什么？

您可以在将索引和值添加到对象中时遍历数组...

您可以找到有关如何迭代对象和数组的示例 here和一个例子 here

Generally, to add an item to object

var array = [{"Location":"Sometown"}, {"Location2":"Sometown2"},    {"Location3":"Sometown3"}],
object = {};
array.forEach(function(element, index) {
    object[index] = element;
});
console.log(object);
