使用 JSzip 时未定义 saveAs

Question

我在尝试执行简单的 jszip 时遇到错误

Uncaught (in promise) ReferenceError: saveAs is not defined

很确定我包含了所有正确的文件，所以我不确定我做错了什么，有人能告诉我吗？

Answer 1

他们的例子中有一条评论：

// see FileSaver.js

如果你想使用 saveAs()

，你需要那个模块

这里是：https://github.com/eligrey/FileSaver.js

Answer 2

在 HTML

中添加以下脚本标签后有效

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

使用 JSzip 时未定义 saveAs

saveAs is not defined when using JSzip

html

javascript
