title: After the mouse has changed the div custom value to the background?
body: <p>I hope that jquery can get the value of DIV change_picture="http://web.com/1.png" when the div class is article-image, and then become the css background. When the mouse is removed, continue. Show the original background <a href="http://web.com/2.png" rel="nofollow noreferrer">http://web.com/2.png</a>.</p>
  
  <p>How to write jquery, ask for guidance. thank you very much</p>
