问题描述

I have a deep nested array of objects and arrays in my project and I want to find a object that has a value in nested array child of itself;我的项目中有一个深层嵌套的对象数组和 arrays，我想找到一个 object，它在其自身的嵌套数组子项中有一个值； Below is a simple example of my json (For a better understanding, I simplified it a bit):下面是我的 json 的简单示例（为了更好理解，我简化了一点）：

                    }
                ]
            }
        ]

for example I want find an object that its child has col-e0a56604-196a-4dcc-a04e-a56968a2f8aa value (in size in i key and I want its parent that's mean a object of cols array with name equal of searched characters)例如，我想找到一个 object，它的孩子有 col-e0a56604-196a-4dcc-a04e-a56968a2f8aa 值（在 i 键中的大小，我想要它的父级，这意味着一个 object 的 cols 数组，名称等于搜索字符）

You have to based the seach on your object structure.您必须根据 object 结构进行搜索。 In your case it could look like this.在您的情况下，它可能看起来像这样。

Your question is a bit hard to understand, but here is a possible solution using object-scan .你的问题有点难以理解，但这里有一个使用object-scan的可能解决方案。 Note that all parents are present in the parents array, so pick whichever one you desire.请注意，所有父母都存在于parents数组中，因此请选择您想要的任何一个。 

 // const objectScan = require('object-scan'); const sections = [{"id":"e9904688-fd8a-476d-8f46-930bc4d888d1","name":"sec-e9904688-fd8a-476d-8f46-930bc4d888d1","rows":[{"id":"2f1bc178-d2bf-4283-ae9c-868513af789f","name":"row-2f1bc178-d2bf-4283-ae9c-868513af789f","cols":[{"id":"adad03c8-60f3-4db1-8c6c-a125bbd7f114","name":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","isEmpty":false,"size":{"lg":{"i":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","x":1,"y":0,"w":12,"h":4},"md":{"i":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","x":1,"y":0,"w":12,"h":4},"sm":{"i":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","x":1,"y":0,"w":12,"h":4},"xs":{"i":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","x":1,"y":0,"w":12,"h":4},"xxs":{"i":"col-adad03c8-60f3-4db1-8c6c-a125bbd7f114","x":1,"y":0,"w":12,"h":4}},"controles":[{"id":"37619580-6ba6-4058-a39b-2d57d23007d6","name":"control name","type":"control type","options":[{},{}]}]}]}]},{"id":"f3f5522c-0b7f-4d6f-84a7-50cce4e92775","name":"sec-f3f5522c-0b7f-4d6f-84a7-50cce4e92775","rows":[{"id":"8263d5fc-4445-4243-8cb2-3853b3918994","name":"row-8263d5fc-4445-4243-8cb2-3853b3918994","cols":[{"id":"e0a56604-196a-4dcc-a04e-a56968a2f8aa","name":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","isEmpty":false,"size":{"lg":{"i":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","x":1,"y":0,"w":12,"h":4},"md":{"i":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","x":1,"y":0,"w":12,"h":4},"sm":{"i":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","x":1,"y":0,"w":12,"h":4},"xs":{"i":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","x":1,"y":0,"w":12,"h":4},"xxs":{"i":"col-e0a56604-196a-4dcc-a04e-a56968a2f8aa","x":1,"y":0,"w":12,"h":4}},"controles":[{"id":"37619580-6ba6-4058-a39b-2d57d23007d6","name":"control name","type":"control type","options":[{},{}]}]}]}]}]; objectScan(['**[*].name'], { filterFn: ({ value, parents }) => { if (value === 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa') { console.log(parents[2]); } } })(sections); // => { id: '8263d5fc-4445-4243-8cb2-3853b3918994', name: 'row-8263d5fc-4445-4243-8cb2-3853b3918994', cols: [ { id: 'e0a56604-196a-4dcc-a04e-a56968a2f8aa', name: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', isEmpty: false, size: { lg: { i: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', x: 1, y: 0, w: 12, h: 4 }, md: { i: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', x: 1, y: 0, w: 12, h: 4 }, sm: { i: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', x: 1, y: 0, w: 12, h: 4 }, xs: { i: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', x: 1, y: 0, w: 12, h: 4 }, xxs: { i: 'col-e0a56604-196a-4dcc-a04e-a56968a2f8aa', x: 1, y: 0, w: 12, h: 4 } }, controles: [ { id: '37619580-6ba6-4058-a39b-2d57d23007d6', name: 'control name', type: 'control type', options: [ {}, {} ] } ] } ] }
