我正在玩一些chrome扩展,我发现了这个例子:http://src.chromium.org/viewvc/chrome/trunk/src/chrome/common/extensions/docs/examples/api/pageAction/pageaction_by_url/
一切正常,但我想创建自己的扩展,我想在特定网站上看到page_action图标,而不是在网址中看到'g'的图标.所以我试着简单地从这个改变脚本:
// Copyright (c) 2011 The Chromium Authors. All rights reserved.

// Called when the url of a tab changes.
function checkForValidUrl(tabId, changeInfo, tab) {
// If the letter 'g' is found in the tab's URL...
if (tab.url.indexOf('g') > -1) {
// ... show the page action.
chrome.pageAction.show(tabId);
}
};
// Listen for any changes …
