getChildren

getChildren( nested:Boolean, tweens:Boolean, timelines:Boolean, ignoreBeforeTime:Number ) : Array

Returns an array containing all the tweens and/or timelines nested in this timeline.

Parameters

  • nested: Boolean

    (default = true) - Determines whether or not tweens and/or timelines that are inside nested timelines should be returned. If you only want the "top level" tweens and timelines, set this to false.

  • tweens: Boolean

    (default = true) - Determines whether or not tweens should be included in the results.

  • timelines: Boolean

    (default = true) - Determines whether or not timelines should be included in the results.

  • ignoreBeforeTime: Number

    Number (default = -Infinity) - All children with start times that are less than this value will be ignored.

Returns : Array​

An Array of child tweens and timelines.

Details​

Returns an array containing all the tweens and/or timelines nested in this timeline that match the provided criteria. Callbacks (delayed calls) are considered zero-duration tweens.

//first, let's set up a master timeline and nested timeline:
var master = gsap.timeline({ defaults: { duration: 1 } }),
  nested = gsap.timeline();

//drop 2 tweens into the nested timeline
nested.to("#e1", { duration: 1, x: 100 }).to("#e2", { duration: 2, y: 200 });

//drop 3 tweens into the master timeline
master
  .to("#e3", { top: 200 })
  .to("#e4", { left: 100 })
  .to("#e5", { backgroundColor: "red" });

//nest the timeline:
master.add(nested);

//get only the direct children of the master timeline:
var children = master.getChildren(false, true, true);

console.log(children.length); //"3" (2 tweens and 1 timeline)

//get all of the tweens/timelines (including nested ones) that occur AFTER 0.5 seconds
children = master.getChildren(true, true, true, 0.5);

console.log(children.length); //"5" (4 tweens and 1 timeline)

//get only tweens (not timelines) of master (including nested tweens):
children = master.getChildren(true, true, false);

console.log(children.length); //"5" (5 tweens)
