这是 实验性技术
检查 浏览器兼容性表格 要小心谨慎在生产中使用这之前。

origin 只读特性在 WindowOrWorkerGlobalScope interface returns the origin of the global scope, serialized as a string.

句法

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

值

A USVString .

范例

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" .
