JSON到多维Javascript对象

Question

I'm loading an external JSON file into javascript, the JSON file looks like this:

[
  {
    "name":"Apple",
    "year":8,
    "records_lost":12367232
  },
  {
    "name":"178.com",
    "year":7,
    "records_lost":10000000
  },
  {
    "name":"Accendo Insurance Co. ",
    "year":7,
    "records_lost":175350
  }
]

Eventually, I want to access the data via a Javascript object like this (don't mind the syntax). The point is that name will be a parent with its own meta-data.

"Apple":
  "year":8,
  "records_lost":12367232
"178.com":
  "year":7,
  "records_lost":10000000

This is the code I've already written for this part, which doesn't make name parent yet and only saves the last row of the JSON file into the array ( += instead of = would fix this, but delivers ugly values, obviously).

  function initJSON() {
    loadJSON(function(response) {
      var JSONParse = JSON.parse(response);
      var i;
      for (i in JSONParse) {
        JSONdata.name.i = JSONParse[i].name;
        JSONdata.year = JSONParse[i].year;
        JSONdata.recl = JSONParse[i].records_lost;
      }
    });
  }
  initJSON();

Thanks in forward.

Answer 1

it should be :

var i;
for (i in JSONParse) {
    JSONdata.name = i.name;
    JSONdata.year = i.year;
    JSONdata.recl = i.records_lost;
}

unless your loop was different:

var i;
for (i = 0; i < JSONParse.length; i++) { 
    JSONdata.name = JSONParse[i].name;
    JSONdata.year = JSONParse[i].year;
    JSONdata.recl = JSONParse[i].records_lost;
}

Try utilizing Array.prototype.map() , delete operator

 var data = [{ "name": "Apple", "year": 8, "records_lost": 12367232 }, { "name": "178.com", "year": 7, "records_lost": 10000000 }, { "name": "Accendo Insurance Co. ", "year": 7, "records_lost": 175350 }]; var res = data.map(function(val, key) { var obj = {}; obj[val.name] = val; delete obj[val.name].name; return obj }); document.getElementsByTagName("pre")[0].textContent = JSON.stringify(res, null, 4); 

 <pre></pre>
