设置值到deletionStatusText在fineuploader中不起作用

Question

这是一个跟进question from.

我正在尝试利用当前的删除过程进行标题更新（在我的情况下）。实现有效，但statusText仍然是默认值（正在删除....）。根据上面链接中的答案，我尝试设置deletionStatusText =＆＃39;正在更新...＆＃39;在DeleteFile选项中。而且，我在DeleteFile中有警告声明。即使在显示警报之前，statusText也已显示“正在删除...”。请参阅screenshot。

我可能会遗漏一些我无法弄清楚缺少的东西。我是否需要在任何其他地方设置状态？
