Find match in JSON Object


This code sample will allow you to look through an array of JSON objects and extract a specific property.


function findInJSON(el, key, id, toReturn) {
for (var q = 0; q < el.length; q++) {
if (el[q][key] == id) {
return el[q][toReturn];
}
}
return false;
}

Directions:

- call findInJSON(el, key, id, toReturn);

- el is the array of JSON objects

- key is the property to be used when searching

- id is the value you are searching for

- toReturn is the property you want to be returned from the matching object
