This is my url to codepen : https://codepen.io/CreatorInCloud/pen/qoYmKR/
The code in $.JSON() is not working and i was using the url ‘https://en.wikipedia.org/w/api.php?action=query&format=json&list=search&srsearch=adams%20brian&srwhat=text&callback=?&origin=*’
Finally it worked 
Sorry, my network was slow at that time, so sorry for wasting your time.
