如何从子'；javascript/vuejs中的s Id

所以我有这个json

                "checked": false
            }],
            "nest_uid": "17_15_1536914882_hwzB7dIn9x",
            "checked": false
        }
    ]
}

您可以看到，每个级别上都有两个属性

nest\u uid

已被选中

现在我得到了子元素的

嵌套uid

，因此我需要将所有

都标记为false，除了选中的一个及其父元素

比如说

如果
nest_id='17_15_1536914882_yhHDzQsDSK'

输出

递归确实是这里的答案。这样的东西应该有用，即使它不是最漂亮的：

function selectInJSON(uid, current) {
  current.is_selected = current.nest_uid === uid

  Object.values(current).forEach((child) => {
      if (Array.isArray(child)) {
        child.forEach((item) => {
          selectInJSON(uid, item)
          if (item.is_selected) current.is_selected = true
        })
      }
      else if (Object(child) === child) {
        selectInJSON(uid, child)
        if (child.is_selected) current.is_selected = true
      }
  })
}

你必须采取递归的方法，不能用简单的过滤器解决。这个JSON结构是否像你在问题中发布的那样固定？@SivcanSingh是的，嵌套uid是固定的，选择的是我为了创建场景而添加的hwat，所以基本上我只想向用户显示立即树，隐藏所有其他内容你必须采用递归方法，不能用简单的过滤器解决。这个JSON结构是否如你在问题中所发布的那样固定？@SivcanSingh是的，嵌套uid是固定的，所选的是为了创建场景而添加的hwat，所以基本上我只想向用户显示即时树，隐藏所有其他元素该代码是否也会使所有其他元素为false？它是否会返回任何内容？它会在适当的位置修改对象。如果您想返回它，您必须使其不可变或进行深度克隆。如果它对你有用，别忘了把答案标为正确！这段代码是否也会使其他所有元素都为false？它是否会返回任何内容？它会就地修改对象。如果您想返回它，您必须使其不可变或进行深度克隆。如果它对你有用，别忘了把答案标为正确！
