Question

为什么最新版本的ScrollMagic会在下面给出此错误？

未捕获的ReferenceError：未定义ScrollScene

这是我在guide之后的测试代码：

$(function() {
    // Init Controller
    var scrollMagicController = new ScrollMagic();

    // Create Animation for 0.5s
    var tween = TweenMax.to('#animation', 0.5, {
        backgroundColor: 'rgb(255, 39, 46)',
        scale: 7,
        rotation: 360
    });

    // Create the Scene and trigger when visible with ScrollMagic
    var scene1 = new ScrollScene({
        triggerElement: '#scene',
        offset: 150 /* offset the trigger 150px below #scene's top */
    })
    .setTween(tween)
    .addTo(scrollMagicController);

    // Add debug indicators fixed on right side
    scene1.addIndicators();
});

如果我使用的是最新版本：

<script src="//cdnjs.cloudflare.com/ajax/libs/ScrollMagic/2.0.5/ScrollMagic.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/ScrollMagic/2.0.5/plugins/debug.addIndicators.min.js"></script>

完整错误：

Uncaught ReferenceError: ScrollScene is not defined
    at HTMLDocument.<anonymous> (basic.php:66)
    at c (jquery.min.js:3)
    at Object.fireWith [as resolveWith] (jquery.min.js:3)
    at Function.ready (jquery.min.js:3)
    at HTMLDocument.H (jquery.min.js:3)

但是，如果我使用这个版本（我想更老），它可以正常工作：

<script src="https://cdnjs.cloudflare.com/ajax/libs/ScrollMagic/1.3.0/jquery.scrollmagic.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/ScrollMagic/1.3.0/jquery.scrollmagic.debug.js"></script>

我的HTML：

  <div class="post">
        <span class="glyphicon glyphicon-grain"> </span>
        <h2> Lorem ipsum dolor sit amet, consetetur sadipscing elitr</h2>
    </div>

    <div class="post" id="scene">
        <span class="glyphicon glyphicon-lamp" id="animation"> </span>
        <h2> Lorem ipsum dolor sit amet, consetetur sadipscing elitr</h2>
    </div>

任何想法为什么？

修改

如果我使用github中的指南：

// Init Controller
var scrollMagicController = new ScrollMagic.Controller();

// Create Animation for 0.5s
var tween = TweenMax.to('#animation', 0.5, {
    backgroundColor: 'rgb(255, 39, 46)',
    scale: 7,
    rotation: 360
});

// Create the Scene and trigger when visible with ScrollMagic
var scene1 = new ScrollMagic.Scene({
    triggerElement: '#scene',
    offset: 150 /* offset the trigger 150px below #scene's top */
})janpaepke-ScrollMagic/scrollmagic/minified/plugins/debug.addIndicators.min.js
.setTween(tween)
.addTo(scrollMagicController);

// Add debug indicators fixed on right side
scene1.addIndicators();

我会收到此错误：

Uncaught TypeError: (intermediate value).setTween is not a function
    at HTMLDocument.<anonymous> (basic.php:70)
    at c (jquery.min.js:3)
    at Object.fireWith [as resolveWith] (jquery.min.js:3)
    at Function.ready (jquery.min.js:3)
    at HTMLDocument.H (jquery.min.js:3)

为什么！????他们的文件很糟糕！

编辑2：

所以我使用下载的版本：

<script src="libs/janpaepke-ScrollMagic/js/lib/greensock/TweenMax.min.js"></script>
<script src="libs/janpaepke-ScrollMagic/scrollmagic/minified/plugins/animation.gsap.min.js"></script>

<!-- should be replaced with minified version when development is finished -->
<script src="libs/janpaepke-ScrollMagic/scrollmagic/minified/plugins/jquery.ScrollMagic.min.js"></script>

<!-- should be removed when development is finished -->
<script src="libs/janpaepke-ScrollMagic/scrollmagic/minified/plugins/debug.addIndicators.min.js"></script>

我得到更多错误：

文件名和文件夹结构完全混乱。令人困惑和不一致！

Answer 1

尝试使用

new $.ScrollMagic.Scene

而不是

new ScrollMagic.Scene

应该有所帮助。如果您使用的是1.3.0版本，则无需使用“$。”

Answer 2

您也必须导入gsap插件。检查scrollmagic文件夹。的 animation.gsap.min.js
