How to get an Key value pair from a array of objects in angular

Question

Sample array of objects:

{"29": "DTE Queue", "30": "Services Reporting Sales", "31": "Services Reporting Ops", "41": "UPLOAD", "55": "Support Report"}.

I'm getting input from user as 'sup'. Then output should be {"55": "Support Report"}.

function getKeyByValue(object, value) {
  return Object.keys(object).find((key) => object[key] === value);
}

Answer 1

You can convert the object to an array of entries, find the entry and convert it back to an object:

const obj = {"29": "DTE Queue", "30": "Services Reporting Sales", "31": "Services Reporting Ops", "41": "UPLOAD", "55": "Support Report"};

function getObjectByValue(object, value) {
  try {
    return Object.fromEntries([Object.entries(object).find(([key, val]) => val.toLowerCase().includes(value.toLowerCase()))]);
  } catch (err) {
    console.error('Object not found');
    return {};
  }
}

console.log(getObjectByValue(obj, 'sup'));
console.log(getObjectByValue(obj, 'sup2'));
