A better user script for HKEJ.com
Last time I have shown a very simple/stupid user script to auto login hkej.com ( 信報財經新聞網站 ）
In fact, what it does is not auto log in, but check if you are checked out and try to log-in once. It does not safe you ( me ) from cookie expires. Although it does re-log and so user can go back and click on the link to escape.
I find no way to manipulate cookie with GreaseMonkey directly. This is not too bad in terms of security. I don’t have to steal cookies. I just want to revive them.
1) The simplist trick is to reload the page:
window.setTimeout(window.location.reload,29min_later);
It works. But what if the user left some valuable words in forms ?
All such data will be vanished.
2) Do some minimal ajax load
I cannot sure why, but it does not work. It seems the ajax load within Greasemonkey is bounded by some shields.
3) Load some data into an iframe, and reload the iframe from time to time.
It works. Rather than expected, I can hide those iframe without anyharm.
So I rewrite the code a little bit. This time, I have also taken reference from a famous user script to handle username and password.
Wondering if I shall submit it to userscripts.org ….
Would do so if anyone interested.
