Question

我想知道如何解析任何JSON文件而不管内容如何。例如，我必须解析以下JSON。如何在不使用JSON文件中的单词/键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"
}]

你需要一个循环来遍历a中的每个元素，并循环遍历对象中的每个键。（另外你在第一个对象中缺少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]);
  }
}

如何在javascript中解析JSON文件而不了解文件内容？
