3.设置基本属性和事件

🦋3.1 设置深色模式

通过darkMode()接口可以配置不同的深色模式。

• WebDarkMode.Off模式表示关闭深色模式。

• WebDarkMode.On表示开启深色模式，且深色模式跟随前端页面。

• WebDarkMode.Auto表示开启深色模式，且深色模式跟随系统。

• forceDarkAccess()接口可将前端页面强制配置深色模式，且深色模式不跟随前端页面和系统。配置该模式时候，需要将深色模式配置成WebDarkMode.On。

🦋3.3 在新窗口中打开页面

开发者可以使用multiWindowAccess()接口来设置网页是否可以在新窗口中打开。通过调用此接口并传入相应的参数，可以控制网页是否允许使用新窗口。

当网页请求在新窗口中打开时，应用将收到Web组件的新窗口事件，可以通过onWindowNew()接口来处理此事件。在此接口中，开发者可以根据需要创建新的窗口来处理Web组件的窗口请求。

🦋3.4 管理位置权限

对于某个网站进行位置权限管理的过程中，开发者可以通过onGeolocationShow()接口来向用户请求位置权限。该接口会触发一个位置权限请求对话框，用户可以选择是否授权该网站获取设备的位置信息。

Web组件会根据用户的选择，将权限授予或拒绝。如果权限被授予，前端页面将能够获取设备的位置信息。如果权限被拒绝，前端页面将无法获取设备的位置信息。

在进行位置权限请求之前，开发者需要在应用的配置文件中添加ohos.permission.LOCATION权限，以确保应用有权限获取设备的位置信息。
