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。但是，裁剪框或其他名称似乎位于图像下方，或者它只是透明的。

这是我的代码，您可以复制并粘贴以进行检查。

<script type="text/javascript" src="http://yui.yahooapis.com/2.9.0/build/imagecropper/imagecropper-min.js"></script>
<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>

这是雅虎提供的演示 URL http://developer.yahoo.com/yui/examples/imagecropper/simple_crop_clean.html

请帮我。提前致谢！

<!--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，即

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

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

此代码然后框消失请检查您的代码。也许javascript是必不可少的，或者您可能缺少其他东西。最好保留所有的js和css，并尝试调试删除。您将了解具体点。我的代码有希望工作，如果不是，请告诉我。:)
