Question

我在尝试做一个简单的jszip

时遇到错误

未捕获（承诺）ReferenceError：未定义saveAs

很确定我收录了所有正确的文件，所以我不确定我做错了什么，有人可以赐教我吗？

Answer 1

他们的例子中有一条评论：

// see FileSaver.js

如果您想使用saveAs()

，则需要该模块

这是：https://github.com/eligrey/FileSaver.js

Answer 2

在HTML中添加以下脚本标记后

<script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/1.3.8/FileSaver.js"></script>

使用JSzip时未定义saveAs
