Find by key deep in a nested array

Question

Let\'s say I have an object:

[
    {
        \'title\': \"some title\"
        \'channel_id\':\'123we\'
        \'options\': [
                    {

Recursion is your friend. I updated the function to account for property arrays:

function getObject(theObject) {
    var result = null;
    if(theObject instanceof Array) {
        for(var i = 0; i < theObject.length; i++) {
            result = getObject(theObject[i]);
            if (result) {
                break;
            }   
        }
    }
    else
    {
        for(var prop in theObject) {
            console.log(prop + ': ' + theObject[prop]);
            if(prop == 'id') {
                if(theObject[prop] == 1) {
                    return theObject;
                }
            }
            if(theObject[prop] instanceof Object || theObject[prop] instanceof Array) {
                result = getObject(theObject[prop]);
                if (result) {
                    break;
                }
            } 
        }
    }
    return result;
}
