Are you able to see the coding of a Javascript function on a webpage your viewing? Is there a way using Google Chrome DevTools for example?
Specifically, I want to figure out how to code something like this !Example 1
from this page http://www.indeed.com/cmp/Bruce-Productions/jobs/Graphic-Designer-0a8d9cff06bf2790
Thanks in advance for any help!
In the browser you do right click to open a menu and select "View Source Code". Then you can read or save that page to analyze the content for any image or script.
But your question is so generic maybe you should try something basic and try to builds thing from there. Otherwise make a more specific question of what you want to do.
