Display A Popup Only Once Per User

There have already been answers to this question but I am still unsure exactly how it works.

I am using the following HTML in my footer.php:

<div id="popup">
    <div>
        <div id="popup-close">X</div>
            <h2>Content Goes Here</h2>
    </div>
</div>

and the following Javascript:

$j(document).ready(function() {
    $j("#popup").delay(2000).fadeIn();
    $j('#popup-close').click(function(e) // You are clicking the close button
    {
    $j('#popup').fadeOut(); // Now the pop up is hiden.
    });
    $j('#popup').click(function(e) 
    {
    $j('#popup').fadeOut(); 
    });
});

Everything works great, but I want to only show the pop up once per user (maybe using the cookie thing all the forum posts go on about) but I do not know exactly how to incorporate it into the JS above.

I know that I will have to load the cookie JS in my footer with this:

<script type="text/javascript" src="scripts/jquery.cookies.2.2.0.min.js"></script> 

But that is all I understand, can anyone tell me exactly how the JS/jQuery should look with the cookie stuff added?

Thanks

Answer

*Note : This will show popup once per browser as the data is stored in browser memory.

Try HTML localStorage.

Methods :

• localStorage.getItem('key');
• localStorage.setItem('key','value');

$j(document).ready(function() {
    if(localStorage.getItem('popState') != 'shown'){
        $j('#popup').delay(2000).fadeIn();
        localStorage.setItem('popState','shown')
    }

    $j('#popup-close, #popup').click(function() // You are clicking the close button
    {
        $j('#popup').fadeOut(); // Now the pop up is hidden.
    });
});
