如何格式化我的JSON？

Question

我有这种格式的JSON

[
  {"name":"universityID","value":"454"},
  {"name":"grade","value":"88"},
  {"name":"date","value":"15-Jan-2016"},
  {"name":"address","value":"Washington"}
]

我想要我的JSON

{
  "universityID":"454",
  "grade":"88",
  "date":"15-Jan-2016",
  "address":"Washington"
}

Answer 1

您只需迭代您的数组并将每个属性填充到新对象中：

var input = [
  {"name":"universityID","value":"454"},
  {"name":"grade","value":"88"},
  {"name":"date","value":"15-Jan-2016"},
  {"name":"address","value":"Washington"}
];

var output = {};

input.forEach(function(attr) {
  output[attr.name] = attr.value;
});

console.log(output);

编辑：如果universityID需要是一个数组：

var input = [
  {"name":"universityID","value":"454"},
  {"name":"grade","value":"88"},
  {"name":"date","value":"15-Jan-2016"},
  {"name":"address","value":"Washington"}
];

var output = {};

input.forEach(function(attr) {
  if (attr.name == "universityID") {
    if (!(attr.name in output)) output[attr.name] = [];
    output[attr.name].push(attr.value);
  } else {
    output[attr.name] = attr.value;
  }
});

console.log(output);
