Javascript: 当 url 是 localhost 时加载脚本

Question

当 url 是本地主机时，我需要加载文件。

我预计：

if (location.hostname === "localhost" || location.hostname === "127.0.0.1"){
 <script src="script-local.js"></script>
} else { //
 <script src="https://example.com/script.js"></script>
}

可能吗？

我认为这样的方法可行：

<html>
    <body>
        <script>
            var script = document.createElement("script");

            if (location.hostname === "localhost" || location.hostname === "127.0.0.1") {
                script.src = "http://somedomain.com/somescript.js";
            } else {
                script.src = "http://somedomain.com/someotherscript.js";
            }
  
            document.body.appendChild(script);
        </script>
    </body>
</html>
