对于带有查询字符串的完整URL：

document.location.toString()

对于主机URL:

window.location

获取当前页面URL:

window.location.href

对于那些想要一个实际的URL对象的人，可能是一个以URL为参数的实用程序：

const url = new URL(window.location.href)

https://developer.mozilla.org/en-US/docs/Web/API/URL

Use:

window.location.href

正如评论中所指出的，下面这行行是有效的，但它对Firefox来说是错误的。

document.URL

请参阅DOMString类型的URL，只读。

location.origin+location.pathname+location.search+location.hash;

and

location.href

也一样。
