safari - 为什么在 Safari 6 和 Mobile Safari (iOS 6) 中的所有属性上未定义 window.location

Question

当我输入

window.location

我在所有属性上都不确定。

这是我的控制台：

Answer 1

此代码适用于 Safari (6.0.1) 及更早版本

    // Get location for REST TARGETS

    lcnURI = window.location.protocol + "//" + window.location.hostname + ":"
            + window.location.port + "/rest/";

当您查看日志时，window.location 似乎“脱离了上下文”。但是在使用的地方还好。

Answer 2

I can confirm this (Version 6.0 (8536.25)). Seems to be a Safari bug, as far as I can tell.

Tested on jsbin (http://jsbin.com/enugoj/1/):

console.log(window.location);
console.log(window.location.pathname);​

Results in Safari's console:

Location
  ancestorOrigins: undefined
  hash: undefined
  host: undefined
  hostname: undefined
  href: undefined
  origin: undefined
  pathname: undefined
  port: undefined
  protocol: undefined
  search: undefined
  __proto__: LocationPrototype

Results in Chrome (Version 21.0.1180.89):

Location
  ancestorOrigins: DOMStringList
  assign: function () { [native code] }
  hash: ""
  host: "jsbin.com"
  hostname: "jsbin.com"
  href: "http://jsbin.com/enugoj/1"
  origin: "http://jsbin.com"
  pathname: "/enugoj/1"
  port: ""
  protocol: "http:"
  reload: function () { [native code] }
  replace: function () { [native code] }
  search: ""
  toString: function toString() { [native code] }
  valueOf: function valueOf() { [native code] }
