How to change a timeline parameter that has already been set?

[Mr Pablo 6 Likes (Newbie)]

I have a basic timeline where I am setting the X parameter based on the width of a DIV.

 

After the timeline completes, I am changing the DIV content, and the width changes.

 

How would I go about changing what the X parameter is, now that I have changed what it's initial value was.

 

Pseudo-code example:

 

var width;

 

width = $(div).width();

 

timeline =  timeline.fromTo( ($(div), time, { x: 0 }, { x: width } );

 

function ontimelinecomplete {

    $(div).content(new content), width = $(div).newWidth()

}

 

This is what I have currently, but the timeline still uses the original width.

Hi Mr Pablo 

 

you need to use .invalidate() method : http://greensock.com/docs/#/HTML5/GSAP/TimelineMax/invalidate/

 

pls check this out : 

See the Pen bddvgy by MAW (@MAW) on CodePen

What if I'm using fromTo?

 

That uses two sets of values and I only need to change the second, "to", value.

You can see here, I am trying to get timeline.vars.css, but it returns undefined.

for .fromTo() tweens do like this :

var Tween = TweenMax.fromTo(".red",10,{x:0},{x:100});

var tl = new TimelineMax();
tl.add(Tween)
  .to(".blue", 2, {x:100});

$("#change").on("click", function() {
  Tween.vars.startAt.x = 200; // from value
  Tween.vars.css.x = 500; // to value
  tl.seek(0).invalidate().restart();
});

Please see my edit above, I cannot access vars.css or vars.startAt either, for my timeline.

I don't see in your code where you're trying to access the vars.

Crap, the jsfiddle didn't save, I have fixed it.

towards the bottom, in the changeFeedContent function, I get undefined for timeline.vars.startAt and css

You are trying to read properties of the timeline that don't exist. But why don't you just clear the timeline and start over.
