history.state's Issues

API 文档

API 文档

JavaScript 接口  

historyState.isSupported()  

判断当前环境是否支持通过 history.state 属性获取当前 state。

这是一个非常重要的方法,如果你的业务需要使用 history.state 特性,务必先使用此方法探测其是否可用。

参数

(无)

返回值

布尔值。

示例

// 在 iOS 5.x 或 Android 4.0~4.3 下运行:
historyState.isSupported()  // => false

historyState.polyfill()
historyState.isSupported()  // => true

[已弃用] historyState.polyfill()  

初始化方法。

(注:从 2.0 版开始,此方法会自动执行,无需手动调用。)

新增构建机制

要实现以下需求:

  • 发布 UMD 包
  • 在发布版中滤除调试代码

单元测试中的探测 Android 系统版本的部分应该改为探测 WebKit 版本

在 Android 平台下,浏览器对 HTML5 特性的实现与否实际上取决于其使用的 WebKit 版本,而非 Android 版本。由于 Android 各版本原生内置 WebKit 引擎的版本是固定的,由 Android 系统版本来推测其内置浏览器的行为是可行的。

但 Andriod 系统下的第三方浏览器(比如 QQ 浏览器等)有可能自带内核,其 WebKit 版本可能超越系统。在这种情况下,现有测试是通不过的。

_hasHistoryAPI

function _hasHistoryAPI() {
        return 'onpopstate' in window &&
            'replaceState' in history && typeof history.replaceState === 'function' &&
            'replaceState' in history && typeof history.replaceState === 'function'
    }

应该是检测pushState 和 'replaceState' 吧,代码里面2个'replaceState'
