[英]Background.js not working Chrome Extension
I'm new to chrome extensions and cannot seem to figure out how the background concept works. 我是Chrome扩展程序的新手,似乎无法弄清楚背景概念是如何工作的。 I am building a counter extension that keeps counting even when the user closes the extension (but not the browser) and wanted to do a simple test to see if I could figure out how to use the background file. 我正在构建一个计数器扩展,即使用户关闭扩展(但不是浏览器),并且想要做一个简单的测试,看看我是否可以弄清楚如何使用后台文件。 Below is my attempt to create a function that activates everytime a user clicks on a tab (outside of my extension) and when they click on 5 tabs, the alert hits. 下面是我尝试创建一个功能,每当用户点击选项卡(我的扩展名之外)时激活该功能,当他们点击5个选项卡时,警报就会响起。 I cannot figure out why this doesn't work. 我无法弄清楚为什么这不起作用。
background.js: background.js:
var counter = 0;
chrome.browserAction.onClicked.addListener(function(tab){
counter++;
if (counter == 5) {
alert("Hi");
}
});
manifest.json: manifest.json的:
{
"name": "Hello World!",
"description": "My first packaged app.",
"version": "0.1",
"permissions": ["tabs", "http://*/*"],
"manifest_version":2,
"content_scripts": [ {
"js": [ "jquery-1.9.1.js", "myscript.js" ],
"matches": [ "http://*/*", "https://*/*"]
}],
"background": {
"scripts": [
"background.js"
]
},
"browser_action": {
"default_title": "10,000 Hours",
"default_icon": "icon16.png",
"default_popup": "index.html"
},
"icons": {
"16": "icon16.png",
"48": "icon48.png",
"128": "icon128.png"
}
}
It is working for me with following code. 它通过以下代码为我工作。
{
"name": "Popping Alert",
"description": "http://stackoverflow.com/questions/15194198/background-js-not-working-chrome-extension",
"background": {
"scripts": [
"background.js"
]
},
"version": "1",
"manifest_version": 2,
"browser_action": {
"default_title": "Click Me"
}
}
var counter = 0;
chrome.browserAction.onClicked.addListener(function (tab) {
counter++;
if (counter == 5) {
alert("Hey !!! You have clicked five times");
}
});
