Get text from web

I make small games in Construct 2, and I need a little help with javascript, ajax, or something. I need to search for something in a specific internal web page.

I need to search if my 'pub-id' is in the 'ads.txt' of each domain where my game is. The problem is that I can't figure out how to crawl to other internal pages, because using 'document' didn't help me out.

What i've tried:

var id='2314121'; //my id var found = document.documentElement.innerHTML.indexOf(id); //it's searching my id in the HTML code if(found >= 0) //it will return -1 if it's not there, and position if's there { alert('Found it at position: '+found); }

The problem is that this will search just on the current page, and I need to search in a specific one. I need to search in 'www.domainexample.com/ads.txt'.

I found how to tell on which site I am with 'window.location.host', but I'm stuck here. I can't crawl from the index to ads.txt.

Anybody knows how to make this?

Thank you! :)

Ok, I found how to do that.

The next question is: I can output the result in Construct 2? Like, if I have a variable "aux" in Construct 2 and the variable "found" from the Javascript code, it's there a way for me to transfer the information from the code to my variable, like ex: "aux = found".

Javascript code:

var found;
$.get(
 'http://domain-example.com',
 {paramOne : 1, paramX : 'abc'},
 function(data) {
 found = data.indexOf('your-text');
 if(found >=0)
 {
 alert('Your text was found at position: '+found);
 }
 }
);

Done.

Here is the Javascript code:

var found = -1;
$.get(
 'http://domain-example.com',
 {paramOne : 1, paramX : 'abc'},
 function(data) {
 gasit = data.indexOf('the word are you looking for');
 if(found >= 0)
 { 
 c2_callFunction('cauta_pub_id', [found]);
 
 }
 }
);
