click a link or click submit without refreshing

user634850

i have header, main_content, footer, right, and left content

my right content has a random link

i don’t want my right content to be refresh when I click a random link
and the main_content would be the output

is it possible that a web page without refreshing the page when you click a link or click submit button and still you can see the url on your browser what you have clicked? how do to that?

thanks!
