[jQuery] Re: callback in a plugin

[Alexandre Plennevaux]

Ok, in the meanwhile i found the plugin documentation (sitting right on the 
homepage, i must had a fit of blindness :)) so i just have to do it as an 
additional option. Thanks a lot for the clear explanation renato ! I know this 
sounded like a stupid question, but i'm just not feeling at home with 
javascript.  Although with jquery, i already feel in my county :)

The principle is quite simple.

When the plugin has completed its processing, and it is up to the 
plugin's author to know when it has, you just call your callback 
function if setted in the options.

Something like this:

var options = {callback:function(){alert("I've finished!");}}
jQuery.fn.my_plugin_with_callback = function(options) {
  this.each(function(){
        ...do some processing
  });
  if(options.callback) callback();
}
