Well that doesn’t sound like something a beginner would be doing. I mean when you asked your question you were extremely vague and said “can I get the HTML tags of the page?” and then left it at that. Now all of a sudden you have quite the vocabulary in order to properly explain your problem, such as “looking to get the dynamically generated HTML code when I make an HTTP request” which demonstrates you know exactly what you’re talking about.
Perhaps you should have said that in the first place then? But if you are a beginner then that’s probably why you’re not familiar with the innerHTML property in JavaScript (except jQuery has a simple wrapper too). So even though this has nothing to do with web-based user interfaces for video games, I guess I’ll answer your question since it seems applicable, which is that this is probably what you’re looking for…
ue4('myeventname', document.body.innerHTML);
or with jQuery…
ue4('myeventname', $('body').html());
You should obviously be able to apply this to any HTML tag that you’d like to query. I’m not going to sit here and explain to you how jQuery works, but I’ll at least give you raw JavaScript just in case:
document.getElementById('myidname').innerHTML
And that will work for any HTML ID. If you don’t even know what those are, then same answer, I’m not going to sit here and explain all that to you. Go read, learn, ect.
