Here's a jQuery solution:

HTML

<form ...>
   <input type="text" id="first"/>
   <input type="text" id="second"/>
</form>

JavaScript

$(function ()
{
    $('#first').blur(function ()
    {
        alert('show the popup here');
    });
});

Basic demo .

window.open() demo . Disclaimer: this behavior is extremely annoying to users.
