从Youtube视频评论页面获取所有用户ID /作者

问题描述：

As the title says I want to get all the users ids who posted a comment on specific Youtube videos. I have looked all over for something like this, the Youtube data API comes close but I can only get it to pick up the comments and not the user it came from. The other method I've looked at doing is using greasemonkey + jquery to get them but jquery doesn't run on Youtube properly and alot of javascript functions don't either. Can anyone suggest a way this can be done?

Here is part of a script I was testing in greasemonkey:

var elem = document.getElementsByClassName('author')[1];
var mystring = elem.nextSibling;
var mynewString = mystring.innerHtml;

document.getElementById('google-cookie-alert').innerHTML = mynewString;

But it comes back undefined.

正如标题所示，我希望获得所有在特定Youtube视频上发表评论的用户ID。我已经看了很多这样的东西，Youtube数据API接近但我只能得到它来接收评论而不是它来自的用户。我看过的另一种方法是使用greasemonkey + jquery来获取它们，但是jquery不能正确地在Youtube上运行，而且很多javascript函数也没有。任何人都可以建议这样做吗？ p>

这是我在greasemonkey中测试的脚本的一部分： p>

  var elem =  document.getElementsByClassName（'author'）[1]; 
var mystring = elem.nextSibling; 
var mynewString = mystring.innerHtml; 
 
document.getElementById（'google-cookie-alert'）。innerHTML = mynewString; 
   code>  pre> 
 
 但它未定义。 p> 
  div>

答

Here you go. This will log out all the usernames for each of the commenters displayed.

var elements = document.getElementsByClassName("author");
for (var i = 0; i < elements.length; i++){
    if(elements[i].children.length > 0)
         console.log(elements[i].children[0].text)
}
