load() function 's problem - Cross sites issue?

load() function 's problem - Cross sites issue?

in my html page, i have a .load function to load a page from a public page on the Internet.
it works when i preview it  in my computer.

it does not work when i put it on the server..

How can i solve? is that something like the server is blocking the cross site request? i don't  know if this issue would happen to .load() function
