"Is there a JavaScript code snippet that can retrieve information from a JSON file

Is there a way to create a custom JavaScript function that can extract specific data from a JSON object based on certain keywords? I am working with a Task Manager API and would like to automatically populate fields based on the task title. Here is an example of the JSON data:

{
 "data": {
    "boards": [
      {
        "owner": {
          "id": 555555555
        },
        "groups": [
          {
            "id": "new_group",
            "title": "Forecasts",
            "items": [
              {
                "id": "355670938",
                "name": "PIPE: Production & Client Management | STAGE: New Support Intake | NAME: TESTY | DATE: 10/27/2019 | TIME: 8:00 am | TIME ZONE: Central Time | DURATION: 60 minutes | TYPE: All Virtual | AUDIENCE VIEW:"
              }
            ]
          }
        ]
      }
    ]
  },
  "account_id": 55555555
}

I specifically want to retrieve the information for DATE, TIME, DURATION, and TYPE from items.name. How can I create a function to extract only this data?

Answer №1

To begin, you must first pinpoint the exact location from which you wish to extract the information.

Next, simply separate the content using pipes, followed by colons.

let targetStr = getTree().data.boards[0].groups[0].items[0].name;
let fields = ['DATE', 'TIME', 'DURATION', 'TYPE'];

console.log(extractData(targetStr, fields));

function extractData(str, fields) {
  return str.split(/\s*\|\s*/).reduce((res, entry) => {
    let dat = entry.split(/\s*:\s*/);
    return fields.indexOf(dat[0]) > -1 ? Object.assign(res, { [dat[0]]: dat[1] }) : res;
  }, {});
}

function getTree() {
  return {
    "data": {
      "boards": [{
        "owner": {
          "id": 555555555
        },
        "groups": [{
          "id": "new_group",
          "title": "Forecasts",
          "items": [{
            "id": "355670938",
            "name": "PIPE: Production & Client Management | STAGE: New Support Intake | NAME: TESTY | DATE: 10/27/2019 | TIME: 8:00 am | TIME ZONE: Central Time | DURATION: 60 minutes | TYPE: All Virtual | AUDIENCE VIEW:"
          }]
        }]
      }]
    },
    "account_id": 55555555
  };
}

.as-console-wrapper {
  top: 0;
  max-height: 100% !important;
}

One possible solution is to split the items' names using a pipe character without ever using it in the data. Then, you can filter out only the elements that start with "DATE:", "TIME:", "DURATION:", or "TYPE:".

items.name.split('|').filter(data => /^(DATE:|TIME:|DURATION:|TYPE:)/.test(data));
