使用requirejs加载blue-imp fileupload会在blobSlice上抛出错误

Question

我正在使用requirejs

加载fileupload插件

我正在加载插件如下：

define([
        'jquery',
        'jquery.iframe-transport',
        'jquery.fileupload-ui'
    ], function(
        jquery,
        itransport,
        fileupload_ui
    )
    {

此stackoverflow问题确认了这一点：

requireJS with fileupload plugins

当＆＃34; load-image-meta＆＃34;在那些行执行：

    loadImage.blobSlice = hasblobSlice && function () { 

未捕获的TypeError：无法设置属性＆＃39; blobSlice＆＃39;未定义的。

这是因为loadImage作为参数传递为未定义，一旦我们已经在line 23上定义了依赖性，我就无法找出原因。

有人可以帮助我吗？

附加信息（下）

以下是requirejs.config.paths

中为每个插件定义的路径列表

Answer 1

正如@ant_Ti所提及的那样，对我的问题发表评论我必须强制requirejs在加载load-image之前加载load-image-meta因为这个原因我将以下代码添加到我的requirejs中。 config.shim对象：

require.config({
    shim: {
        'jquery.fileupload-ui': {
            deps: ['load-image']
        }
    }
});

这可确保在我们尝试加载jquery.fileupload-ui时，load-image已经可用。
