如何在不了解文件内容的情况下解析 javascript 中的 JSON 文件？

How to parse a JSON file in javascript without having any knowledge about the contents of the file?

我想知道如何解析任何 JSON 文件而不考虑其内容。比如我要解析下面的JSON。我如何在不使用 JSON 文件中的 words/keys 的情况下解析它并调用值？

var a = [{
    "Master Row": "P558:15",
    "Prefix*": "5C34",
    "Base*": "1508",
    "Suffix*": "CA",
    "Weight Unit of Measure": "lb"
}, {
    "Master Row": "P558:16",
    "Prefix*": "5C34",
    "Base*": "1508",
    "Suffix*": "CA",
    "Weight Unit of Measure": "lb"
}]

您将需要一个循环来遍历 a 中的每个元素，并需要一个循环来遍历对象中的每个键。（此外，您还缺少第一个对象中前缀和基数之间的逗号）

var a= [ { "Master Row":"P558:15", "Prefix*":"5C34","Base*":"1508", "Suffix*":"CA", "Weight Unit of Measure":"lb" }, { "Master Row":"P558:16", "Prefix*":"5C34", "Base*":"1508", "Suffix*":"CA", "Weight Unit of Measure":"lb" } ];

for(i=0;i<a.length;i++){
  var temp=a[i];
  for(key in temp){
    console.log(key+' '+temp[key]);
  }
}
