Origin nullmeans you are loading the HTML document directly from your file system. You can't use XMLHttpRequest without HTTP.

Originnull意味着您直接从文件系统加载 HTML 文档。如果没有 HTTP,您就不能使用 XMLHttpRequest。

Either install a web server for your development, or dynamically generate a <script src="..."></script>instead.

要么为您的开发安装一个 Web 服务器,要么动态生成一个<script src="..."></script>
