Rails spinoffs - Feb 2008 - setTimeout and increment

hi

just a fast question, really dont get it :

_up: function(val,pourcent) {


			this.val = val;
			this.pourcent = pourcent;

				var k=0;
				if(k<=val){
					$(pourcent).update(parseInt(k/3)+''%'');
					z=0;
					while(z<100)
					++z;
					setTimeout(function()
{this._up(this.val,this.pourcent);}.bind(this), 80);
					++k;
				}

	},

just a code to increment and screen a var but stay at zero.
tx for any help :)

yes sry , it s  really mean nothing ;;)


to make a summary
i try to increase a percentage ''k'' limited by
''val'' in the loop.
the setTimout should make a break to display the increase of
''k'' on
screen like this  1.2.3.4 etc etc  till ''val'' is reached..
of course like this, the percentage stuck at 0.

i try so many thing to get it work ,
i try to get out the this by reference

function Ref( o_, fct_){
  return( function(){o_[ fct_]()});
}
setTimout(Ref( this, this_up), 80);
no error and stuck at 0


i really dont know how to do this.
hope yu can figure out sthg!!:)

itself?

I''m not sure if I understand correctly what you want. If it is
something that updates a container element with an increasing number
(from 0 to a provided limit), then this will do it:

var progressIndicator = function(element, upTo) {
  var element = $(element), upTo = upTo || 100, percent = 0;
  new PeriodicalExecuter(function() {
    if (percent >= upTo) this.stop()
    element.update(percent++ + "%");
  }, 0.05);
}

progressIndicator("container"); // will go all the way up to 100%
progressIndicator(someElement, 50); // will finish in 50%

Best,
-Nicolas
