我对编码很陌生，目前，我正在编写一个 React 本机项目。对不起，如果问题太简单了。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，因为数据将是动态的，并且名称可能会随着时间而改变。例如，我应该怎么做才能访问“SBI PHARMA - 常规计划 -GROWTH”的“_figure”下的“14.9918670876748”，而后者又位于“Equity - Pharma”下。我想检索所有项目的“_figure”。我试过 for..in 循环，但它只返回嵌套对象的索引。有什么方法可以使用索引浏览 JSON 文件？

提前谢谢你。

抱歉英语不好。

【问题讨论】：

  • 你为什么首先使用对象然后使用数组来达到这个目的？
  • 您要访问所有数字吗？
  • 嗨，Nadir，我想访问所有数据。 JSON 数据以这种结构提供给我。
  • 把所有的图都重调成一个数组可以吗？
  • 是的，没问题，Nadir。

If you want to find the specific just change the variables the corresponding 
names [find] i.e "Equity - Pharma" then subFind i.e "SBI PHARMA - REGULAR 
PLAN -GROWTH"

for(var index in values) {
    if(index === find) {
        var nextIndex = values[index];
        for(var nextFind in nextIndex) {

  • 非常感谢，邪恶的猪排博士。

【解决方案2】：

Object.prototype.hasOwnProperty() 应该可以解决问题。这将为您提供迭代时的键和值。 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
  }
}

    【解决方案3】：

    使用它从对象中提取所有 _figure 作为数组。 

    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);
