Change HTML value based on dragging position

Recommended Posts

Initially, the green box is moving from left to right and the counter number is decreasing from 47,650 to 14,000 but after green box reach to right position, the drag feature is enabled and user can drag green box from right to left and vice versa. The problem I am facing is after dragging, the counter number should also increase and decrease respective to the position of greenbox. Like if I drag greenbox from right to left, the value of counter should increase from 14,000 to 47,650 and if I drag from left to right, the value should decrease from 47,650 to 14,000. Any help will be appreciated

Hey Pro C and welcome to the forums. Thanks for being a club GreenSock member!

 

You were very close. The main thing is that you need to change your shadowUpdate function. 

function shadowupdate() {
  console.log(this.x / 920);
  var value = 33650 - (33650 * this.x / 920) + 14000;
  document.getElementById("eclipse__counter").innerHTML = formatter.format(value);
}

I also changed your draggable a bit:

Draggable.create(".eclipse__drag--sun", {
  type: "x",
  edgeResistance: 0.9,
  bounds: { minX: 0, maxX: 920 },
  throwProps: true,
  overshootTolerance: 0,
  onDrag: shadowupdate,
  onThrowUpdate: shadowupdate
});

If you don't want the number to ever be able to be outside of your bounds, set the edgeResistance to 1.
