 <html>
 <body>
 <p>
 Click the button to replace "Microsoft"
 with "jb51.net" in the paragraph below:
 </p>
 <p id="demo">Visit Microsoft!</p>
 <button onclick="myFunction()">Try it</button>
 <script>
 function myFunction()
 {
 var str=document.getElementById("demo").innerHTML;
 var n=str.replace("Microsoft","jb51.net");
 document.getElementById("demo").innerHTML=n;
 }
 </script>
 </body>
 </html>
