javascript JSON.stringify（）将数组放在同一行

Question

我正在使用JSON.stringify ，我想知道是否有一种方法可以将数据保持在数组的同一行上。

我希望它看起来像这样：

"bob": {
  "college": "UCLA",
  "favorite_color": "green",
  "favorite_numbers": [12, 42]
},
"fred": {
  "college": "USC",
  "favorite_color": "blue",
  "favorite_numbers": [10, 16]
}

但是它出来像：

"bob": {
  "college": "UCLA",
  "favorite_color": "green",
  "favorite_numbers": [
    12,
    42
  ]
},
"fred": {
  "college": "USC",
  "favorite_color": "blue",
  "favorite_numbers": [
    10,
    16
  ]
}

任何建议都很好。

Answer 1

您可以使用replacer参数来实现：

 var obj = { "bob": { "college": "UCLA", "favorite_color": "green", "favorite_numbers": [12, 42] }, "fred": { "college": "USC", "favorite_color": "blue", "favorite_numbers": [10, 16] } }; console.log('This is what you really want:'); console.log(JSON.stringify(obj, function(a, b) { return (Object.prototype.toString.call(b) === '[object Array]') ? JSON.stringify(b) : b; }, 4)); console.log('This is your result:'); console.log(JSON.stringify(obj, null, 4));
