Google Chrome Cookies扩展程序：“Can not call method'set'of undefined” [英] Google Chrome Cookies Extensions: "Cannot call method 'set' of undefined"

问题描述

我在开发Chrome扩展程序时尝试使用Google Chrome Cookie扩展程序。我已按照此处的说明进行操作： http://code.google.com/chrome/ extensions / cookies.html

I'm trying to use the google chrome cookies extension when developing a chrome extension app. I've followed the instructions found here: http://code.google.com/chrome/extensions/cookies.html

我的清单文件已经有权限和cookie。

My manifest file already has the permissions and cookies.

问题现在我似乎无法调用饼干扩展中的任何方法

The problem is now I can't seem to call any of the methods in the cookies extension

var newCookie = {'url:': 'http://*/*', 'name': 'routeCookie', 'value': route.tag[document.boxForm.routeBox.options.selectedIndex]};
chrome.cookies.set(newCookie);

错误：未捕获的类型错误：无法调用方法未定义

Error: UnCaught TypeError: Cannot call method 'set' of undefined

推荐答案

我敢打赌，您正试图从内容脚本运行它。大多数API方法仅在后台页面中可用。

I bet you are trying to run it from a content script. Most API methods are available only in background pages.
