JavaScript函数未执行



我需要一双额外的眼睛。我已经克服了很多次,但都没有成功。问题是getFilename函数,顾名思义,它应该获取上传文件的文件名。不管我做什么,它似乎都不起作用,所以我一定错过了什么。

好的,所以我删除了最后一个答案,因为我终于花时间执行了您的代码。正如你所拥有的,它对我有效。

以下是我建议你做的。删除你的HTML和JavaScript,将它们放在一个独立的HTML文件中,然后加载到你的浏览器中。添加必要的标记以使其完整。(另外,你缺少了一个"身体"标签,并不是说这是你问题的根源。)

然后测试它。如果它有效,那么你的问题来自其他地方,而不是你提供的代码。你有页眉和页脚代码吗?

如果它不起作用,开始部分删除HTML和JavaScript,直到它起作用。使用它可以隔离错误的原因。

祝你好运。
