Error:

Uncaught TypeError: Cannot call method 'getSelected' of undefined

清单

    "name": "YouTube Fix", 
    "version": "0.0.1", 
    "manifest_version": 2, 
    "description": "Fix some of the annoying little things in YouTube.", 
    "icons": {

Background.js

//this is what is giving me the error: 
chrome.tabs.getSelected(null, function (tab) { 
    myFunction(tab.url); 
}); 

function myFunction(tablink) { 
    if (tablink == "http://www.youtube.com") { 
     window.location = "http://www.youtube.com/feed/subscriptions/u"; 
    } 
    document.getElementById("comments-textarea").disabled = false; 
}

从这里引：https://groups.google.com/a/chromium.org/forum/?fromgroups=#!topic/chromium-extensions/A5bMuwCfBkQ

chrome.tabs.getSelected() is deprecated. The following page explains how to use chrome.tabs.query instead: http://code.google.com/chrome/extensions/whats_new.html#16 The relevant bit of text is: """ The methods getAllInWindow() and getSelected() have been deprecated. To get details about all tabs in the specified window, use chrome.tabs.query() with the argument {'windowId': windowID}. To get the tab that is selected in the specified window, use chrome.tabs.query() with the argument {'active': true}. """

chrome.tabs.getSelected是deprecated。使用chrome.tabs.query代替：

chrome.tabs.query({ 
    "active": true 
}, function(tab){ 
    console.log(tab[0]); //selected tab 
});

另外，内容脚本can not accesschrome.tabs的API。这样做：

chrome.extension.getBackgroundPage().chrome.tabs.query(...

（。这可能无法正常工作未测试）

被弃用并不意味着它被删除。 “chrome.tabs.getSelected”在测试后台页面中工作得很好。此外，如果问题是getSelected已被删除，错误将会是“Uncaught TypeError：Object＃
