How to do it?

 

I tried: below script

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.1/jquery-ui.js"></script>

 

But the script is shows only first textbox value another text box value is not shown when click the other textboxes
