This plugin is utility for convinience of communication between iframes in
HTML page,
it is mimicking from Qt’s signal/slot concept.

you can do with jquery.sigslot.js:

• send signal to N-depth iframe page
• async. or sync. communication
• exclude or include particular iframe
• allow multiple slot or just one

Usage

([ .. ] for opton , ‘|’ for seperator)

1. slot

• $.slot.add( 'sig/slot id', function [,repeatable] )
  repeatable = true | false
  false: allow only one slot function for signal-id (default)
  true: allow every slot function for signal-id, even it is identical. so, slot function is called as many as times you registered
  ex) $.slot.add( ‘test’, [a,b,c,d], true );
• $.slot.remove( 'sig/slot id'[, function]);
  • if function is omitted, remove all slot functions for signal-id
• $.slot.countOf( 'sig/slot id');
  • return number of registered slot function for signal-id

2. signal

• $.signal( 'sig/slot id', args, [, options ] );

  • args: arguments passing to slot function. wrap by [] if you want to pass more than one.
  • options : simple object, for …

  direction = $.signal.SELF | $.signal.UPLINK | $.signal.FOLLOWLINK | $.signal.OTHER | $.signal.BROADCAST
  purpose: direct where to pass signal. default for all iframes include window.self
  - $.signal.SELF (send signal only to current page that the signal occur)
  - $.signal.UPLINK (send signal only to parents iframes EXCLUDE current page that the signal occur)
  - $.signal.FOLLOWLINK (send signal only to child iframes EXCLUDE current page that the signal occur)
  - $.signal.OTHER (send signal to all iframe pages EXCLUDE current page that the signal occur)
  - $.signal.BROADCAST (send signal to all iframes INCLUDE current page that the signal occur)

  sync = true | false
  purpose: select async or sync call. boolean type. default is sync.

  * $.signal will NOT cause error, if there’s no slot function for signal-id. It will do nothing.
