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，所以我一直在使用Ajax根据需要提取位。我想要检索的元素之一是blueimp文件上传器。除了我在尝试添加文件时从控制台获得的消息外，一切似乎都很好。
未捕获的TypeError：无法读取属性＆＃39; parseMetaData＆＃39;未定义的
显示处理图像，但随后......没有。
如果有人能够告诉我为什么我会收到这个错误，也许还有如何解决它，我将非常感激。

希望这就是你所需要的。
仔细观察后，我认为这可能是造成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();
},

确保您没有在模式等中加载load-image-all，这是我的问题。无论我等多久，我都会得到90％的时间：
未捕获的TypeError：无法读取属性＆＃39; parseMetaData＆＃39;未定义的
另外10％的时间它奇迹般地工作......
所以，再次 - 在主模板上放置脚本是我的修复。

-- my fault was that I should have added `https://` in front of [BlueImp][1] . Apologies for the same

jquery.fileuploader-image 收到loadImage（第41行）：
}(function ($, loadImage) {
如果在该脚本之前未包含 load-image.all.min.js ，则会发生此错误（第275行）：
loadImage.parseMetaData
