推荐答案
ejs -模板在您的节点服务器上呈现，其中没有对 navigator 的引用(或 window ).但是，您可以做的是将上述代码包含在< script> -标签中，并将其返回到模板中:
The ejs-template is rendered on your node-server, where no reference to navigator (or window for that matter) exists. What you can do, however, is to include above code in a <script>-tag and return this in your template:
// your-template.ejs
<h1>Hello EJS World </h1>
<script>
if ('geolocation' in navigator) {
console.log("geolocation supported");
} else {
console.log("Geolocation is not supported by this browser.");
}
</script>
