这是一个实验中的功能
此功能某些浏览器尚在开发中,请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订,所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

WindowOrWorkerGlobalScope 接口的 origin 只读属性返回全局范围的 origin, 序列化为一个字符串。

Syntax

let myOrigin = self.origin; // or just origin

Value

A USVString.

Examples

Executed from inside a worker script, the following snippet will log the worker's global scope's origin to the console each time it receives a message

onmessage = function() {
  console.log(self.origin);
};

If the origin is not a scheme/host/port tuple (say you are trying to run it locally, i.e. via file:// URL), origin will return the string "null".
