Hello /g/ I want to make some kind of a script in a website that

Wh...what?

What is it that needs explanation ?

You need to use JavaScript to perform an XMLHttpRequest.

>>58875303
That doesn't work across domains, but it would be a useful tool to update your own website with incoming data

OP use servlets or whatever you use for Java web development

There's a 60% chance this thread is bait, and a 40% chance OP is stone cold retarded, but Ill bite anyway.

If you want a website to run your script at all, it needs to be your website, or a site with a xss vulnerability.

As for getting that script to read you info from another site, you can write a program in C that makes an html request, and process the data that is returned by the server. Or you can write a js script to do the same thing.

To be honest, I'm not sure what you are really asking for, but I hope this illuminated something for you in your dark, dark world.

It does if you use YQL.

OP here.
My apology for everyone in this thread. I'll explain more.
When I said I know C, C++ and Java I meant that I never programmed a website before.
Now I want to make a website. My website would require some information from another website that I don't own but the information is public.
What should I learn to be able to accomplish this ?

YQL seems to rely on a (now defunct?) yahoo api/proxy

>>58875387
Google Java scraper, apache tomxat, servlets

Learn a bit if html and you should be able to do something

It still works as it always has.

>>58875440
all right this seems simple enough. Thanks

>>58875387
research what scraping is, and find out how to do it in one of the languages you know

The languages I know aren't useful in making a website.
