chrome.tabs.onUpdated.addListener为每个页面获得两次或更多的完整状态 [英] chrome.tabs.onUpdated.addListener is getting complete status twice or more for each page
问题描述
这是我的脚本，它使用onUpdated.addListener检查每个url：
chrome.tabs.onUpdated.addListener（函数（tabId，changeInfo，tab）{
alert（changeInfo.status）;
if（changeInfo.status =='complete'）{
if（tab.url.indexOf（in .yahoo.mail）！== -1）{
alert（tab.url）;
chrome.tabs.update（tabId，{url：https://accounts.google.com/ ServiceLogin}）;
// injectToTab（tab）;
}
}
}）;
这里是Manifest代码：
{
name：LeoPlugin For Test，
version：1.6，
manifest_version：2，
content_security_policy：script-src'self'; object-src'self'，
description：自动扩展名，
background：{
脚本：[js / eventPage.js]，
persistent：false
}，
content_scripts：[
{
matches： [http：// * / *]，
js：[js / eventPage.js]
}
]，
图标：{ 48：images / bob48.png，128：images / bob128.png}，//定义任何图标大小以及您想要使用的文件。 48/128等
browser_action：{
default_icon：images / bob.png，//你想在chrome工具栏上显示什么图标
default_popup ：testwatch.html//点击按钮时弹出的页面。
}，
permissions：[
tabs，http：// * / *，https：// * / *//跨站点访问请求

预先感谢您的时间。
这是Chrome Issue 162543 ，它在2012年12月5日标记为已修复。
解决方法： strong>（不再需要）
将活动页面设为后台页面通过更改
background中的代码：{
scripts：[js /eventPage.js]，
persistent：false
}，
到
background：{
scripts：[js / eventPage.js]，
persistent：true
}，
并使用后台页面开发直到修复交付。
其他要点： 看看你的manifest.json为什么 让我知道如果你需要更多信息。 Here is my Script, which uses onUpdated.addListener to check each url: And here is the Manifest code: Anything missing in the above code that can prevent getting 'complete' status more than once. And also here is my HTML code: Thanks in advance for your time. This was a known bug in Chrome Issue 162543 which was marked as fixed on 2012-12-05. Workaround: (not needed anymore) Make Event Page to Background Page by changing code from to and moving ahead by using background pages for development till the fix is delivered. Other Points: After a look at your manifest.json why does Let me know if you need more information. 这篇关于chrome.tabs.onUpdated.addListener为每个页面获得两次或更多的完整状态的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
background：{
scripts：[js / eventPage.js]，
persistent：false
}，
content_scripts：[
{
：[http：// * / *]，
js：[js / eventPage.js]
}
]，
js / eventPage.js 是内容脚本以及background \event脚本;获取 chrome.tabs.onUpdated.addListener（）的代码将无法在内容脚本，请删除此代码
chrome.tabs.onUpdated.addListener(function (tabId, changeInfo, tab) {
alert(changeInfo.status);
if (changeInfo.status == 'complete') {
if (tab.url.indexOf("in.yahoo.mail") !== -1) {
alert(tab.url);
chrome.tabs.update(tabId, { url: "https://accounts.google.com/ServiceLogin" });
//injectToTab(tab);
}
}
});
