javascript - ScrollMagic 插件正在运行，但不是 "tying"滚动动画

Question

我正在尝试使用 scrollmagic 插件实现 SVG 文本滚动，如下所示:

http://janpaepke.github.io/ScrollMagic/examples/advanced/svg_drawing.html

但是，当我从此处获取示例代码并将其合并到我的站点中时，SVG 动画有效，但 svg 动画是同时发生的，而不是与窗口滚动的 1:1 关系。

我假设一定有某种场景或 Controller 属性必须启用此功能？这是我为此使用的特定代码，从我的元素中裁剪出来:

HTML:

<div class="resume-block-3 container">
            <svg version="1.1" xmlns="http://www.w3.org/2000/svg" width="350" height="200">
                <path id="word" style="stroke-linecap: round; stroke-linejoin: round; stroke-dasharray: 1009.23px; stroke-dashoffset: 1009.23px;" fill="none" stroke="#fff" stroke-width="5" d="M22.328,70.018c9.867-7.4,10.724,20.434,13.014,28.694c-0.08-9.105-1.308-31.463,11.936-31.886

                <path id="dot" style="stroke-linecap: round; stroke-linejoin: round; stroke-dasharray: 44.2974px; stroke-dashoffset: 44.2974px;" fill="none" stroke="#fff" stroke-width="5" d="M247.003,38.567c-7.423,1.437-11.092,9.883-1.737,11.142c14.692,1.978,13.864-13.66,1.12-8.675"></path>
            </svg>
        </div>

JS:

function pathPrepare ($el) {
        var lineLength = $el[0].getTotalLength();
        $el.css("stroke-dasharray", lineLength);
        $el.css("stroke-dashoffset", lineLength);
    }

    var $word = $("path#word");
    var $dot = $("path#dot");

    // prepare SVG
    pathPrepare($word);
    pathPrepare($dot);

    // init controller
    var controller = new ScrollMagic.Controller();

var thirdBlockEntrance = new TimelineMax()
        .add(TweenMax.to($word, 0.9, {strokeDashoffset: 0, ease:Linear.easeNone})) // draw word for 0.9
        .add(TweenMax.to($dot, 0.1, {strokeDashoffset: 0, ease:Linear.easeNone}))  // draw dot for 0.1
        .add(TweenMax.to("path", 1, {stroke: "#33629c", ease:Linear.easeNone}), 0);         // change color during the whole thing


var tweenScene3 = new ScrollMagic.Scene({
        triggerElement: '.container.resume-block-3',
        offset:200
    })
    .setTween([thirdBlockEntrance])
    .addIndicators()
    .addTo(controller);

我再说一遍，这是从更大的元素中裁剪出来的，所以如果有什么遗漏，请先在评论中询问我，我会更新帖子。

感谢您的帮助。

您需要在场景选项中包含持续时间。这将决定控制时间轴进度的滚动过程的长度:

     triggerElement: '.container.resume-block-3',
            offset:200,
            duration: 800
