我正在学习如何创建Chrome扩展程序.我刚开始开发一个来捕捉YouTube活动.我想将它与YouTube Flash播放器一起使用(稍后我将尝试使其与HTML5兼容).
manifest.json的:
{
"name": "MyExtension",
"version": "1.0",
"description": "Gotta catch Youtube events!",
"permissions": ["tabs", "http://*/*"],
"content_scripts" : [{
"matches" : [ "www.youtube.com/*"],
"js" : ["myScript.js"]
}]
}
myScript.js:
function state() { console.log("State Changed!"); }
var player = document.getElementById("movie_player");
player.addEventListener("onStateChange", "state");
console.log("Started!");
问题是控制台给了我"开始!" ,但没有"状态改变!" 当我播放/暂停YouTube视频时.
将此代码放入控制台时,它可以正常工作.我究竟做错了什么？
javascript google-chrome youtube-api google-chrome-extension content-script
我是谷歌Chrome扩展程序的新手.我在扩展程序中创建了一个按钮.使用该按钮,我想将用户重定向到另一个站点(如"www.example.com").我有以下代码,我为重定向编写,但它不起作用.
相关问题.
