在Chrome擴展中顯示警告對話框

Question

我想在用戶單擊我的擴展名圖標時顯示簡單的alert。我曾嘗試這樣的代碼：chrome.browserAction.onClicked.addListener( alert(1) );， 這裏是我manifest：

{ 
    "manifest_version": 2, 

    "name": "sample", 
    "description": "des", 
    "version": "1.0", 

    "browser_action": { 
    "default_icon": "icon.png" 
    }, 
    "permissions": [ 
    ] 
} 

如何顯示警報onClick事件？

更新：

根據documention它是這樣的：

chrome.browserAction.onClicked.addListener(function() { 
    alert('Hello, World!'); 
}) 

這裏是sample from Google (zip-file)：

// Copyright (c) 2011 The Chromium Authors. All rights reserved.

var min = 1; 
var max = 5; 
var current = min; 

function updateIcon() { 
    chrome.browserAction.setIcon({path:"icon" + current + ".png"}); 
    current++; 

    if (current > max) 
    current = min; 
} 

chrome.browserAction.onClicked.addListener(updateIcon); 
updateIcon();
