【问题描述】：
也许这是构建它的错误方法，但我有很多信息被提供给我的网页，所以我一直在根据用户使用 Ajax 的需要提取信息。我想检索的元素之一是 blueimp 文件上传器。除了我尝试添加文件时从控制台收到的消息之外，一切似乎都很好。
未捕获的类型错误：无法读取未定义的属性“parseMetaData”
处理图像出现，但随后……什么也没有。
如果有人能告诉我为什么我会收到此错误，以及如何解决它，我将非常感激。

仔细检查后，我认为这可能是导致我的一些问题的部分：
loadImageMetaData: function (data, options) {
if (options.disabled) {
return data;
}
var that = this,
dfd = $.Deferred();
loadImage.parseMetaData(data.files[data.index], function (result) {
$.extend(data, result);
dfd.resolveWith(that, [data]);
}, options);
return dfd.promise();
},【问题讨论】：

我们可以看看代码吗？另外，您如何查看此页面：github.com/blueimp/JavaScript-Load-Image
-
我会尽我所能，但它来自很多地方。感谢您的快速回复。
-
一开始是沼泽标准。我只需要它先加载并运行。
-
从不同的目录调用 ajax。当我显示 $_SERVER 信息时，SCRIPT_FILENAME 显示在该文件夹中。这会阻止脚本查找元数据吗？
