Pulling cookie value with jQuery for MailChimp popup

I'm trying to read a cookie, but don't have a clue how, basically.

The cookies are being set OK, but don't seem to be read properly.

Here's what I have at the moment:

mce_jQuery(document).ready(function(){
    mce_jQuery('#mc_embed_signup').hide();
    cks = document.cookie.split( ';' );
    var show=true;
    for(i=0;i<cks.length;i++){
        parts = cks[i].split('=');
        if( parts[0].indexOf('MCEvilPopupClosed')>0 ) show = false;
    }

It then runs on to do the following, but I'd like to simplify开发者_如何学编程 the above and not worry about the expiry date - only do the if(show=true) bit below when:

IF MCEvilPopupClosed value = yes...

    if (show=true){
        mce_jQuery('#mc_embed_signup a.mc_embed_close').show();
        setTimeout( function(){ mce_jQuery('#mc_embed_signup').fadeIn();} , 1000);
        mce_jQuery('#mc_embed_signup a.mc_embed_close').click(function(){ mcEvilPopupClose();});
    }
});

Not really sure how to go about doing this?

var mycookie = $.cookie('the_cookie')
