Question

所以我正在使用预先构建的Yahoo UI开发一个简单的图像裁剪功能。然而，似乎裁剪框或其他任何东西都在图像下面，或者它可能只是透明的。

这是我的代码，您可以复制并粘贴以进行检查。

<img id="yui_img" src="http://developer.yahoo.com/yui/examples/imagecropper/assets/yui.jpg">
<script>
(function(){var crop = new YAHOO.widget.ImageCropper('yui_img');})();
</script>

以下是Yahoo提供的演示的URL http://developer.yahoo.com/yui/examples/imagecropper/simple_crop_clean.html

请帮帮我。提前谢谢！

<!--there is no custom header content for this example-->

</head>

<body class="yui-skin-sam">


<h1>Simple Crop Interface</h1>

<div class="exampleIntro">
    <p>This example shows how to make an image croppable.</p>

</div>

<!--BEGIN SOURCE CODE FOR EXAMPLE =============================== -->


<img id="yui_img" src="http://developer.yahoo.com/yui/examples/imagecropper/assets/yui.jpg">

<script>
(function() {
    var Dom = YAHOO.util.Dom,
        Event = YAHOO.util.Event;

    var crop = new YAHOO.widget.ImageCropper('yui_img');
})();
</script>

<!--END SOURCE CODE FOR EXAMPLE =============================== -->
</body>
</html>

当我删除最后一个脚本时，

<script>
(function() {
    var Dom = YAHOO.util.Dom,
        Event = YAHOO.util.Event;

    var crop = new YAHOO.widget.ImageCropper('yui_img');
})();
</script>

此代码随后消失，请检查您的代码。也许javascript是必不可少的，或者你可能错过了其他一些东西。最好保留所有js和css并尝试逐个删除调试。您将了解具体点。我的代码有希望工作，如果不是，请告诉我。：）

yui imagecropper出现在图像下？
