ScrollMagic+TweenMax:同时绘制多个SVG路径?

ScrollMagic

 // Prepare SVG
  function pathPrepare_journey($el) {
    var lineLength_journey = $el[0].getTotalLength();
    $el.css("stroke-dasharray", lineLength_journey);
    $el.css("stroke-dashoffset", lineLength_journey);
  }

  var $journey1 = $("path#path1");
  var $journey1_2 = $("path#path2");
  var $journey1_3 = $("path#path3");

  pathPrepare_journey($journey1);
  pathPrepare_journey($journey1_2);
  pathPrepare_journey($journey1_3);

  // Reference to container
  var container = $("#section1");
  var containerHeight = $(container).height();
  var vpHeight = $(window).height();

  // Init controller
  var SVGcontroller_journey = new ScrollMagic.Controller();

  // Build tween
  var tween_journey = new TimelineMax().add(
    TweenMax.to($journey1, 1, { strokeDashoffset: 0, ease: Linear.easeNone })
  );

  // Build scene
  var scene = new ScrollMagic.Scene({
    triggerElement: container,
    duration: containerHeight - vpHeight / 2,
    tweenChanges: true
  })
    .setTween(tween_journey)
    .addIndicators({
      name: "Draw Journey Lines#1",
      colorTrigger: "brown",
      colorStart: "brown",
      colorEnd: "brown",
      indent: 600
    })
    .addTo(SVGcontroller_journey);

它工作得非常好,但是正如您所看到的,我的SVG中有三条单独的路径( $journey1 $journey1_2 $journey1_3 ),而ScrollMagic场景目前只画其中一个, $行程1 ,因为我只能在 TimelineMax()

$行程1 ?

我可以添加其他路径,但它们是连续绘制的:

// Build tween
  var tween_journey = new TimelineMax()
    .add(
      TweenMax.to($journey1, 1, { strokeDashoffset: 0, ease: Linear.easeNone })
    )
    .add(
      TweenMax.to($journey1_2, 1, { strokeDashoffset: 0, ease: Linear.easeNone })
    );
