I am designing a web page. When we click the content of div named mail, how can I show a popup window containing a label email and text box?

Check out jQuery UI Dialog. You would use it like this:

The jQuery:

$(document).ready(function() {
    $("#dialog").dialog();
});

The markup:

<div id="dialog" title="Dialog Title">I'm in a dialog</div>

Done!

Bear in mind that's about the simplest use-case there is, I would suggest reading the documentation to get a better idea of just what can be done with it.

Here is a very simple popup:

<!DOCTYPE html>
<html>
    <head>
        <style>
            #modal {
                position:absolute;
                background:gray;
                padding:8px;
            }

            #content {
                background:white;
                padding:20px;
            }

            #close {
                position:absolute;
                background:url(close.png);
                width:24px;
                height:27px;
                top:-7px;
                right:-7px;
            }
        </style>
        <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
        <script>
            var modal = (function(){
                // Generate the HTML and add it to the document
                $modal = $('<div id="modal"></div>');
                $content = $('<div id="content"></div>');
                $close = $('<a id="close" href="#"></a>');

                $modal.hide();
                $modal.append($content, $close);

                $(document).ready(function(){
                    $('body').append($modal);                       
                });

                $close.click(function(e){
                    e.preventDefault();
                    $modal.hide();
                    $content.empty();
                });
                // Open the modal
                return function (content) {
                    $content.html(content);
                    // Center the modal in the viewport
                    $modal.css({
                        top: ($(window).height() - $modal.outerHeight()) / 2, 
                        left: ($(window).width() - $modal.outerWidth()) / 2
                    });
                    $modal.show();
                };
            }());

            // Wait until the DOM has loaded before querying the document
            $(document).ready(function(){
                $('a#popup').click(function(e){
                    modal("<p>This is popup's content.</p>");
                    e.preventDefault();
                });
            });
        </script>
    </head>
    <body>
        <a id='popup' href='#'>Simple popup</a>
    </body>
</html>

First the CSS - tweak this however you like:

a.selected {
  background-color:#1F75CC;
  color:white;
  z-index:100;
}

.messagepop {
  background-color:#FFFFFF;
  border:1px solid #999999;
  cursor:default;
  display:none;
  margin-top: 15px;
  position:absolute;
  text-align:left;
  width:394px;
  z-index:50;
  padding: 25px 25px 20px;
}

label {
  display: block;
  margin-bottom: 3px;
  padding-left: 15px;
  text-indent: -15px;
}

.messagepop p, .messagepop.div {
  border-bottom: 1px solid #EFEFEF;
  margin: 8px 0;
  padding-bottom: 8px;
}

And the JavaScript:

function deselect(e) {
  $('.pop').slideFadeToggle(function() {
    e.removeClass('selected');
  });    
}

$(function() {
  $('#contact').on('click', function() {
    if($(this).hasClass('selected')) {
      deselect($(this));               
    } else {
      $(this).addClass('selected');
      $('.pop').slideFadeToggle();
    }
    return false;
  });

  $('.close').on('click', function() {
    deselect($('#contact'));
    return false;
  });
});

$.fn.slideFadeToggle = function(easing, callback) {
  return this.animate({ opacity: 'toggle', height: 'toggle' }, 'fast', easing, callback);
};

And finally the html:

<div class="messagepop pop">
  <form method="post" id="new_message" action="/messages">
    <p><label for="email">Your email or name</label><input type="text" size="30" name="email" id="email" /></p>
    <p><label for="body">Message</label><textarea rows="6" name="body" id="body" cols="35"></textarea></p>
    <p><input type="submit" value="Send Message" name="commit" id="message_submit"/> or <a class="close" href="/">Cancel</a></p>
  </form>
</div>

<a href="/contact" id="contact">Contact Us</a>

Here is a jsfiddle demo and implementation.

Depending on the situation you may want to load the popup content via an ajax call. It's best to avoid this if possible as it may give the user a more significant delay before seeing the content. Here couple changes that you'll want to make if you take this approach.

HTML becomes:

<div>
    <div class="messagepop pop"></div> 
    <a href="/contact" id="contact">Contact Us</a>
</div>

And the general idea of the JavaScript becomes:

$("#contact").on('click', function() {
    if($(this).hasClass("selected")) {
        deselect();               
    } else {
        $(this).addClass("selected");
        $.get(this.href, function(data) {
            $(".pop").html(data).slideFadeToggle(function() { 
                $("input[type=text]:first").focus();
            });
        }
    }
    return false;
});
