options( obj )

Deep merge of options objects

Whenever a property is an object on both options objects the two properties will be merged using vjs.obj.deepMerge.

This is used for merging options for child components. We want it to be easy to override individual options on a child component without having to rewrite all the other default options.

Parent.prototype.options_ = {
  children: {
    'childOne': { 'foo': 'bar', 'asdf': 'fdsa' },
    'childTwo': {},
    'childThree': {}
  }
}
newOptions = {
  children: {
    'childOne': { 'foo': 'baz', 'abc': '123' }
    'childTwo': null,
    'childFour': {}
  }
}

this.options(newOptions);

RESULT

{
  children: {
    'childOne': { 'foo': 'baz', 'asdf': 'fdsa', 'abc': '123' },
    'childTwo': null, // Disabled. Won't be initialized.
    'childThree': {},
    'childFour': {}
  }
}

  • obj Object Object whose values will be overwritten
RETURNS:
  • Object NEW merged object. Does not return obj1.
