Question

When creating a plugin in jquery, i am creating my configurable settings like this:

var settings = $.extend( {
    'setting_one'  : 'setting_one_value',
    'setting_two'  : 'setting_two_value'
}, options)

What i would like to do is create another setting which depends on the value of either setting_one or setting_two.

For example:

var settings = $.extend( {
    'setting_one'    : 'setting_one_value',
    'setting_two'    : 'setting_two_value',
    'setting_three'  : setting_one + setting_two,
}, options)

How can i do this?

Answer 1

var ops = (function (){
  var one, two, three
  one = 'foo'
  two = 'baz'
  three = one + ' ' + two
  return {
    one: one,
    two: two,
    three: three
  }
}())

var o = $.extend(ops, options)
