URL.origin - Web API 接口参考 编辑

URL.origin 是一个只读属性，返回一个 USVString 类型值，包含 URL 源经过 Unicode 序列化之后的值, 也就是：

• 对于使用 http 或者 https 协议的 URL, 返回协议名, 然后是 '://', 然后是域, 然后是 ':', 最后是端口号 (默认端口是 80 和 443);
• 对于使用 file: 协议的 URL, 返回值因浏览器而异;
• 对于使用 blob: 协议的 URL, 返回值是 blob: 后跟随的源地址. 例如 "blob:https://mozilla.org" 将会返回 "https://mozilla.org".

Note: 此特性在 Web Worker 中可用。

语法

string = URLObject.origin;

示例

var result = new URL("blob:https://mozilla.org:443/").origin;
// 返回:'https://developer.mozilla.org:443'

[1] Though not grouped in a single abstract interface, this method is directly available on the interfaces that implement it, if this interface is supported.

[2] From Gecko 26 to Gecko 44, this property was on the URLUtils mixin. It has been moves either on the HTMLHyperlinkElementUtils mixin, or directly on the interface.

[3] Before Gecko 49, results for URL using the blob scheme incorrectly returned null.
