Need to implement mobile-friendly popup email disclaimer on website

I'm currently in the process of converting a client's static HTML website to Wordpress.

On the following page, .. notice that when you click on the email links, a disclaimer message is displayed in a popup window:

http://wordpress.silvermanacampora.com/contact-us/

When you click on the "Agree" button in the popup -- only then is the mailto link fired off.  

How would you recommend that I replicate this functionality in a way that's more mobile-friendly?  A javascript confirm dialog?  A lightbox/shadowbox popup?  Please advise .. and provide code samples if possible.  

Thanks,
- Yvan

I would be surprised that your theme does not already utilize jquery or another library like bootstrap (which has modal's built in).   To answer your question, here is one pure js solution http://jsmodal.com/docs/usage.php

To answer your 2nd question, it would be the same way you adjust for any other object on your page.  If your site is responsive, then you would use media queries.

What you are looking for is a modal.  The pop up currently does not work in chrome browser anyway.  

Using jquery ui modal example from http://jqueryui.com/dialog/#modal I have modified to work with your example

  <div id="dialog-modal" title="Basic modal dialog">
    <div class="mailto"></div>
 
  </div> 
</body>
</html>

Open in new window

$(function() {
  $('.emailaddress').click(function(){
    var mailto_name=$(this).text();
    var mailto_link='<a href="mailto:'+mailto_name+'?Subject=Help%20me" target="_top">'+mailto_name+'</a>';
    $('div.mailto').html(mailto_link);
    $( "#dialog-modal" ).dialog({
      height: 140,
      modal: true
    });
  });
  });

Open in new window

1)
$('.emailaddress').click(function(){
This listens for the click on the element that has a class of emailaddress

2)
var mailto_name=$(this).text();
This extracts the the email address from the a link

3)
   var mailto_link='<a href="mailto:'+mailto_name+'?Subject=Help%20me" target="_top">'+mailto_name+'</a>';
Here we create the full mailto link

4)
$('div.mailto').html(mailto_link);
This code places the link we just created into the div with class mailto that is in the body of the modal

5)
$( "#dialog-modal" ).dialog({
      height: 140,
      modal: true
    });

The code above calls the modal to open

Thanks for your reply.  What you've suggested seems as though it might work well on a mobile device.  However .. I have a couple of questions:

1) Is there any way to accomplish this same type of functionality without having to use the JQuery UI library?   I ask because I'm not too keen on the idea of adding more code bloat to my Wordpress site just to accommodate for these disclaimer popups.  

2) Assuming that I have to use JQUery UI for this .. how would I go about increasing the width of the modal window when the website is being viewed on a device other than a mobile device (ie: desktop PC / IPad, etc) ?  Ideally, I'd like for the modal window to be displayed a bit wider/taller when viewed on larger displays.

I am using JQuery .. but I would prefer to not have to also use JQuery UI .. which is a distinctly separate library (and CSS stylesheet) that adds another 250k to the page.  

Thanks for the Pure JS solution, btw.  I will likely use that.

Cheers!

For jquery ui, you don't have to have all of it, you can get just what you need. I am using bootstrap in just about everything I do (or foundation) and I  have been using the modal code built in.
