I am using the below code for fade In pop up. Once user visit one page the pop up come. When user visit another page the pop up not come because I have set the cookie. I want that when user come on the page and does not fill the form the pop up on same or another page should again come. When user fill the fade In form the pop up should not come again on same page or another page. I am using this code on wordpress site.

function ReadCookie(cookieName) {
    var theCookie = " " + document.cookie;
    var ind = theCookie.indexOf(" " + cookieName + "=");
    if (ind == -1) ind = theCookie.indexOf(";" + cookieName + "=");
    if (ind == -1 || cookieName == "") return "";
    var ind1 = theCookie.indexOf(";", ind + 1);
    if (ind1 == -1) ind1 = theCookie.length;
    return unescape(theCookie.substring(ind + cookieName.length + 2, ind1));
}

var cookievalue = ReadCookie("Visit");
if (cookievalue == null || cookievalue == "") {
   // Put Here Your FadeIn/FadeOut code
//Start

    var mce_jQuery = jQuery.noConflict();
    mce_jQuery(document).ready(function(){
    mce_jQuery('#sp').hide();
    cks = document.cookie.split( ';' );
    var show=true;
        for(i=0;i<cks.length;i++){>
          parts = cks[i].split('=');
          if(parts[0]=='MCEvilPopupClosed') show = false;
        }
        if (show){
          mce_jQuery('#sp a.close').show();
          setTimeout( function(){ mce_jQuery('#sp').fadeIn();} , 2000);
          mce_jQuery('#sp a.close').click(function(){ mcEvilPopupClose();});
        }
    });

    mce_jQuery(document).keydown(function(e){
       if (e == null) { 
           keycode = event.keyCode;
       } 
           else { 
           keycode = e.which;
       }
       if(keycode == 27){
               mcEvilPopupClose();
       }
    });

    function mcEvilPopupClose(){
    mce_jQuery('#sp').hide();
    var now = new Date();
        var expires_date = new Date( now.getTime() + 31536000000 );
        document.cookie = 'MCEvilPopupClosed=yes;expires=' + expires_date.toGMTString();
    }

    document.cookie = "Visit=1;path=/;domain=.google.com";
}
else if (cookievalue != null) {
   //Do nothing

}
