如何获取动态节点JSON值

Question

   {       
        noteCount_xxx:
              {
              favorite:"favorite-border",
              id:"noteCount_xxx",
              note:"noteContent",
              title: "notetitle",
            }
    }

• 这个在运行时创建的JSON数据,
• 父母noteCount_xxx是动态的
• 我想获得该父节点的值

• 输出将是

  {favorite:"favorite-border",id:"noteCount_xxx",注意:"noteContent",标题:"notetitle"}

我无法从动态节点获取数据,获取该数据的最佳方法是什么？

Answer 1

您可以使用Object.keys来查找nodeCount_xxx值:

const yourJSON = {       
  noteCount_xxx:  {
    favorite:"favorite-border",
    id:"noteCount_xxx",
    note:"noteContent",
    title: "notetitle",
  }
}

const firstKey = Object.keys(yourJSON)[0]

console.log(yourJSON[firstKey])

或者如果你已经知道了它的价值nodeCount_xxx,那么简单地访问你的对象:

yourJSON[noteCount]
