我有一个Chrome扩展程序,如果window.my_variable_name存在变量,它会尝试查找每个浏览过的网址(以及每个浏览器网址的每个iframe).

所以我写了一小段内容脚本:

function detectVariable(){
    if(window.my_variable_name || typeof my_variable_name !== "undefined") return true;
    return false;
}

在尝试太久之后,似乎Content Scripts在一些沙箱中运行.

有没有办法window从Chrome内容脚本访问该元素？

我正在尝试实现我自己的chrome扩展,在某个特定事件上创建浏览器通知并使用background.js中计算的数据填充弹出窗口

这是mymanifest文件:

{
    "name": "Dummy name",
    "description": "Description",
    "manifest_version": 2,
    "version": "1.1.3",
    "icons": {
        "16": "icon_16.png",
        "48": "icon_48.png",
        "128": "icon_128.png",
        "256": "icon_256.png"
    },
    "browser_action": {
        "default_icon": "icon_48.png",
        "default_title": "Test",
        "default_popup": "popup.html"
    },
    "permissions": ["background","webRequest","webRequestBlocking","webNavigation","tabs","notifications"],
    "background": {
        "scripts":["jquery-1.8.1.min.js","classy.js","background.js"]
    }
}

我在background.js中调用sendMessage

show : function(result) {
    var that = this;
    chrome.extension.sendMessage({greeting: "hello"}, function(response) {
        console.log(response);
    });

    if(window.webkitNotifications) {
        var notification = webkitNotifications.createHTMLNotification('notification.html');
        notification.show();
        setTimeout(function(){
            notification.cancel();
            }, '7000');
        }
    }

我在popup.js中的消息监听器(来自chrome扩展示例)

chrome.extension.onMessage.addListener(
  function(request, sender, sendResponse) {
    console.log(sender.tab ?
                "from a content script:" + …
