API

.getPathValue(path, object)

  • @param {String} path
  • @param {Object} object
  • @returns {Object} value or undefined

Retrieve the value in an object given a string path.

var obj = {
    prop1: {
        arr: ['a', 'b', 'c']
      , str: 'Hello'
    }
  , prop2: {
        arr: [ { nested: 'Universe' } ]
      , str: 'Hello again!'
    }
};

The following would be the results.

goodwin.getPathValue('prop1.str', obj); // Hello
goodwin.getPathValue('prop1.att[2]', obj); // b
goodwin.getPathValue('prop2.arr[0].nested', obj); // Universe

.setPathValue(path, value, object)

  • @param {String} path
  • @param {Mixed} value
  • @param {Object} object

Defining the value in an object at a given string path.

var obj = {
    prop1: {
        arr: ['a', 'b', 'c']
      , str: 'Hello'
    }
  , prop2: {
        arr: [ { nested: 'Universe' } ]
      , str: 'Hello again!'
    }
};

The following would be acceptable.

goodwin.setPathValue('prop1.str', 'Hello Universe!', obj);
goodwin.setPathValue('prop1.arr[2]', 'B', obj);
goodwin.setPathValue('prop2.arr[0].nested.value', { hello: 'universe' }, obj);
