i would like to add this to the jqUploader plugin, so that i could do 
something like:
 
 
function pleaseDoTheseThings (params){
    $("#dothis").show();
}
 
$("input#example1").jqUploader({ 
        background:     "FF9900", 
        barColor:       "FFDD00", 
        allowedExt:     "gif",
        callBack: pleaseDoTheseThings 
    }); 
 
 
Thanks a lot!

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();
}
