api

location = LocationHistory()

Create a new location history instance.

location.current()

Returns the current page object.

location.url()

Return the current page object's url property.

location.go(page, [callback])

Navigate to a new page. page should be an object with a url property.

Optionally, specify a setup function property to be called before the page becomes the current one. setup will be passed a callback function that should be called with a null or Error object as the first property.

location.go({
  url: 'my-url',
  setup: function (cb) {
    setTimeout(function () { // ... do any async operations
      cb(null)
    }, 100)
  }
})

Optionally, specify a destroy function property to be called after the page is replaced with another one.

location.go({
  url: 'my-url',
  destroy: function () {
    // ... do any cleanup operations
  }
})

location.back([callback])

Navigate to the previous page. If there is no previous page, this does nothing.

Optionally, specify a callback function to be called after the next page is loaded (in case it has a setup function).

location.forward([callback])

Navigate to the forward page. If there is no forward page, this does nothing.

Optionally, specify a callback function to be called after the next page is loaded (in case it has a setup function).

location.cancel([callback])

Navigate to the previous page, and remove the current page from the history. If there is no previous page, this does nothing.

If you want the current page to stay in history (accessible via forward()), see back().

Optionally, specify a callback function to be called after the next page is loaded (in case it has a setup function).

location.hasBack()

Returns true if there is a previous page, else false.

location.hasForward()

Returns true if there is a forward page, else false.

location.backToFirst([callback])
