Chrome-Extension: iterate through all tabs?
提问by Skizit
How would I iterate through all tabs a user has open and then check if they have a particular HTML item with id = 'item'?
我将如何遍历用户打开的所有选项卡，然后检查他们是否有特定的 HTML 项目id = 'item'？

You can make it like this :
你可以这样做：
chrome.tabs.getAllInWindow(null, function(tabs){
for (var i = 0; i < tabs.length; i++) {
chrome.tabs.sendRequest(tabs[i].id, { action: "xxx" });
}
});
After that to look after your item, if you can make it like this :
在那之后照顾你的物品，如果你能做到这样：
document.getElementById('item')
Don't forget that you can't manipulate the HTML by using the "background page" So the first code snip is for the background page, and the second have to be on a content script ;)
不要忘记你不能通过使用“背景页面”来操作 HTML 所以第一个代码片段是用于背景页面，第二个代码必须在内容脚本上；)

It appears this method has been deprecated in favor of chrome.tabs.query:
似乎此方法已被弃用，以支持chrome.tabs.query：
http://developer.chrome.com/extensions/tabs.html#method-query
http://developer.chrome.com/extensions/tabs.html#method-query
So now you'd want to do:
所以现在你想做：
chrome.tabs.query({}, function(tabs) { /* blah */ } );
Passing an empty queryInfoparameter would return all of the tabs.
传递空queryInfo参数将返回所有选项卡。

This is a not deprecated vanilla way (may 2019):
这是一种未弃用的香草方式（2019 年 5 月）：
chrome.tabs.query({}, function(tabs){
tabs.forEach(tb => {
chrome.tabs.sendMessage(tb.id, { action: "xxx" });
});
});

I use this one
我用这个
chrome.tabs.getAllInWindow(null, function(tabs) {
$.each(tabs, function() {
// u can use 'this.id' to work with evey tab
});
});
