Omnibox

omnibox 应用程序界面允许向Google Chrome的地址栏注册一个关键字，地址栏也叫omnibox。

A screenshot showing suggestions related to the keyword 'Chromium Search'

当用户输入你的扩展关键字，用户开始与你的扩展交互。每个击键都会发送给你的扩展，扩展提供建议作为相应的响应。

建议可以被格式化多种方式。当用户接受建议，你的扩展被通知可以执行动作。

Manifest

使用omnibox 应用程序界面，必须在 manifest 中包含omnibox 关键字段。需要指定像素为16x16的图标，以便当用户输入关键字时，在地址栏中显示。

如：

{
  "name": "Aaron's omnibox extension",
  "version": "1.0",
  "omnibox": { "keyword" : "aaron" }, 
  "icons": { 
    "16": "16-full-color.png" 
  }, 
  "background_page": "background.html"
}

提示: Chrome 自动创建灰度模式16x16像素的图标。你应该提供全色版本图标以便可以在其他场景下使用。 如：Context menus API

使用全色的16x16像素图标。

示例

从sample page 页面可以找到使用该API的例子。.

应用程序界面参考: chrome.omnibox
