我目前有一个swf，允许您选择并显示一个文件并使用FileReference将其上传到服务器。这很好，但我需要能够选择和显示多个（在某些情况下最多可以显示25个），然后在最后将它们全部上传。Flash AS3 FileReference - 一次选择并上传多个文件
我知道你可以使用FileReferenceList在弹出的对话框中同时选择多个文件，但我的问题是用户需要一次选择一个，做一些东西到那个图像，然后选择另一个，做东西等等......然后在最后他们按下上传时将它们全部上传到服务器上。
是否有可能或有办法让我可以将每个新选定的文件添加到数组中，然后最后它会一次性上传数组中的所有文件或循环遍历每个文件直到数组是否完整？
任何人都可以帮忙吗？我将在下面发布我的工作单文件上传的完整代码。
请，请帮帮忙，我很有限的闪光灯和只学了3-4个月，我一直在坚持，现在一个多星期:(
