使用 javascript 从 json 创建自定义嵌套 output

Question

 let data = { "needData": [ { arrayData: [ { "key": "dummy", "value": "needed value" }, { "key": "secret", "random": "secret_random" }, { "key": "another", "value": "testing" }, { "key": "another_Secret", "random": "testing_value" }, ] } ] }; let json, testing; data.needData.map((value) => { json = { arrayData: [ { needed_key: value.arrayData[0].key, needed_value: value.arrayData[0].value, }, ], }; testing = { arrayData: [ { needed_key: value.arrayData.key, needed_value: value.arrayData.value, }, ], }; }); console.log("value got by running json", json); console.log("value got by running testing", testing);

I am trying to save data in json object by using map function but the problem is I can save data by using needed_key:value.arrayData.key needed_value:value.arrayData.value

if all the needed_key and needed_value are same I can use above code but here problem is key name is same but the needed_value get change by random and value I only want to save values of those data which contain in value not random is there any way I can get key and value value not key and random value

I can use manual code to fetch the data but what if data is more and I don't want to use manual code

Expected Output

{
  "arrayData": [
      {
          "needed_key": "dummy",
          "needed_value": "needed value"
      },
      {
          "needed_key": "another",
          "needed_value": "testing"
      }
  ]
}

Answer 1

This gives your output:

var output = {
  'arrayData': data.needData[0].arrayData
    .filter(x => !Object.keys(x).includes('random'))
    .map(x => {
      return {needed_key: x['key'], needed_value: x['value']}
    })
}
console.log(output);

Array.map and Array.filter implementation.

 let data = { "needData": [ { arrayData: [ { "key": "dummy", "value": "needed value" }, { "key": "secret", "random": "secret_random" }, { "key": "another", "value": "testing" }, { "key": "another_Secret", "random": "testing_value" }, ] } ] }; const output = data.needData.map((value) => { const { arrayData } = value; const opArrayData = arrayData.filter(item => item.key && item.value &&.item;random). const parsedArray = opArrayData:map((node => ({ needed_key. node,key: needed_value. node;value }))): return { arrayData; parsedArray } }). console;log(output);
