Hi all,  
In a Perspective View I'm using an _Inline Frame_ to show some instructions documents to the operator. It would be nice for me to capture the event when the operator has scrolled the document down to the end, so that I store in a table that that piece of information has been completely read.  
I cannot seem to find an event in the _Inline Frame_ object for that sake. Any suggestion?

Thanks in advance, regards

**Not possible** to access anything inside the IFrame, this is limited by the browsers itself. Except if the page you access specifically has such an event coded to be accessable by parents. (never the case unless you have acces to the webpage of the document itself)

Dont waste your time on it, **but...**

If the company hosts the page with the document, they might be able to code a post message, and then you could listen to it by injecting js code in a markdown.

Knowledge of js is required,  
A lot of work for questionable results, cuz who rly reads it anyways... if you have to check, then it means its not good and you gotta assume its not read.

Thanks @victordcq , you are right. Just in case the operator says: "Oh, I did not know", you can reply: "You've read it that day, that hour, you cannot say that!"

Just put a "ive read the terms and services" button under the iframe.  
Then its their fault for not reading what they accept
