jquery - Check for Cookie, if it doesn not exist run script -

i'm struggling use of cookies on html page. have script check see if user has cookie, if not call script open model window

<script type="text/javascript"> jquery(document).ready(function() {   jquery("#mymodal").reveal(); }); </script 

the window contains "yes" , "no" buttons, if user selects "yes" save cookie modal doesn't open on future visits page, if user selects "no" direct them page.

any appreciated!!

1) use jquery cookie library ease of use. https://github.com/carhartl/jquery-cookie
2) check if cookie exists , handle accordingly

if ($j.cookie("nameofyourcookie") == null) { //do stuff if cookie doesn't exist set cookie value of 1 $j.cookie("nameofyourcookie", 1, {expires: 10, path:'/'}); }  else { //they have cookie alert ('you have cookie name nameofyourcookie'); }

thought might edit answer more appropriate question.

        <button class="yes">yes</button>         <button class="no">no</button>       var $j = jquery.noconflict();  $j(document).ready(function(){ //show modal on page load            $j("#mymodal").show();      $j('.yes').click(function(){         $j("#mymodal").hide();         $j.cookie("yesbuttoncookie", 1, {expires: 10, path:'/'});         alert ('you have clicked yes, cookie has been dropped');    });           if ($j.cookie("yesbuttoncookie") == 1){             // don't show div             $j("#mymodal").hide();              alert ('cookie found, cant see mymodal');         }           if ($j.cookie("yesbuttoncookie") == null){                     // cookie not found                     alert ('cookie not found, can see mymodal');                     $j("#mymodal").show();         }         $j('.clearcookie').click(function(){         $j.cookie("yesbuttoncookie", null);         alert('cookie cleared');     });   });
