如何在javascript中使用索引浏览嵌套的JSON文件？

我对编码非常陌生，目前，我正在编写一个React原生项目。对不起，如果问题太简单的话。我尝试了很多导航方法，但都失败了。 我有一个JSON文件，数据如下

我想使用索引浏览JSON，因为数据是动态的，名称可能会随着时间的推移而改变。例如，我应该如何访问“SBI PHARMA-定期计划-增长”的“U图”下的“14.9918670876748”，而“Equity-PHARMA”下的“14.9918670876748”。我想检索所有项目的“\u figure”。我在循环中尝试了..，但它只返回嵌套对象的索引。是否有任何方法可以使用索引浏览JSON文件

先谢谢你

很抱歉英语不好。

Object.prototype.hasOwnProperty应该可以做到这一点。这将在迭代时获得键和值。 例如：

var buz = {
  fog: 'stack'
};

for (var name in buz) {
  if (buz.hasOwnProperty(name)) {
    console.log('this is fog (' + 
      name + ') for sure. Value: ' + buz[name]);
  }
  else {
    console.log(name); // toString or something else
  }
}

使用此链接从对象as数组中提取所有图形

var figures=[];
Object.keys(data.values).forEach(function(val){
 Object.keys(data.values[val]).forEach(function(_val){
    if(data.values[val][_val]&&data.values[val][_val]._figure){
       figures.push(data.values[val][_val]._figure[0]);
    }
  });
})

console.log(figures);

控制台。对数图形；为什么首先要使用object，然后使用array？是否要访问所有图形？hi Nadir，我要访问所有图形。JSON数据是在这个结构中提供给我的。如果所有数据都在一个数组中重新调整，可以吗？是的，没问题，Nadir。非常感谢，Nadir。我会试试这个的。非常感谢，邪恶的波克肖医生~~
