Reading information from another site?
Thanks for the reply declan.
About the iframe: that's not an option for me as I have to do some calculations with the numbers you saw on the site...
About the server-side language: should i use php then?
if yes: how do i move this topic? what would this php script look like?
Well, you can still use the information from the iFrame, but the PHP solution would be my preferred anyway.
Include tutorial. From what I know of PHP, that will work for an internal file, but you can read all about that at php.net.
Declan - I have asked this question and seen similar posts and they all said it was impossible on client-side. Is the hidden IFRAME wheeze an exception to received wisdom?
I will try it soon anyway.
I was going to hide my IFRAME during the inspection phase to speed the process, but I found that rendering proceeds after onLoad fires anyway. So I guessed it would not improve anything.

$raintime = split("[\n| ]+",$raintimestr);
I keeps saying that -9 is the answer and that is not right...
And how could we know which is the correct value? We don't know what is the response. We don't know which are the values of your variables...

What exact calculation are you trying to do? The present one is this, which I somehow doubt is what you want. Though that's not -9 so the values on the page must have changed recently.
Kor is correct; access is denied.
I was under the impression that you could access the contents of an iFrame on the page
The outcome of the calculation is a rainfall depth, so in mm/h. That's always positive, and -9 isn't .
If $raintime is 0, the outcome should be 3.9E-4 mm/h (so almost nothing...)
$raintime is a value between 000 and 255 i think... But i think the problem is that its still a string, not a number.
I tried to convert the raintime to a number using:
but that didn't work.
I hope you guys can help me. Thanks for the effort so far!
Iframe wont work
But you can get the content of a particular text box/div/button etc you can get it. Still the src of the iframe should be in your application. 3rd parties link wont work.
