代码很简单：

chrome的插件主要是放在一个文件夹里面 然后在chrome浏览器里面打包就ok了。

这样：

开始看代码：

==

主控代码

manifest.json

{

"name":"a",

"version": "1.0",

"manifest_version": 2,

"description": "1",

"permissions":[

"tabs",

"https://*/*",

"http://*/*"

],

"browser_action":{

"default_icon":"icon.png",

"default_popup":"popup.html"

},

"background": {

"scripts": ["bg.js"],

"persistent": false

}

}

==

bg.js

console.log("background")

chrome.tabs.onUpdated.addListener(function(tabId , info) {

if (info.status == "complete") {

chrome.tabs.query({'active': true, 'lastFocusedWindow': true}, function (tabs) {

var url = tabs[0].url;

console.log(url)

//if(url=="https://www.baidu.com/"){

// chrome.tabs.executeScript(null,{code:'alert("Hello World!")'});

// }http://user.qzone.qq.com/ removeEventListener

//window.addEventListener("scroll", function(){console.log(8)});

// window.οnscrοll=function(){console.log(123)}

if(url.match('user.qzone.qq.com')){

var strjs='var items=document.getElementsByClassName("item");'+

'for(var i=0;i

// chrome.tabs.executeScript(null,{code:' window.οnscrοll=function(){setTimeout( '+strjs+', 3000) }'});

//ok chrome.tabs.executeScript(null,{code:'window.οnscrοll=function(){ console.log(8888);var items=document.getElementsByClassName("item"); console.log(items)}'});

chrome.tabs.executeScript(null,{code:'window.οnscrοll=function(){ console.log(8888);var items=document.getElementsByClassName("item"); for(var i=0;i

//var items=document.getElementsByClassName("item")

//for(var i=0;i

//var s=items[i].innerHTML

//!s.match('赞')||s.match('取消赞')||items[i].click();

// }

//chrome.tabs.executeScript(null,{code:});

}

});

}

});

==

popup.js

document.getElementById("p1").innerHTML="空间点赞"

==

popup.html

空间点赞

body {

min-width: 100px;

overflow-x: hidden;

}

img {

border: 2px solid black;

vertical-align: middle;

width: 75px;

height: 75px;

}

空间点赞

打包后的效果是：
