<head>
<script language=javascript>
function promptor()
{
  var name=prompt("Please enter your Email","Enter your email");

  // passing javascript
  if (name!=null && name!="")
  {
  location.href="blog_app.php?name=" +name;
  }
  else
  {
   document.writeln("please fill your email");
  }

</head>

<body>
 <input name="Downlaod" type="submit" id="Downlaod" onclick="promptor()"/>
</body>
