Examples of cookie usage in JavaScript

Recently, I was working on a project that involved writing some cookie examples. I found that I still have many shortcomings in js, but I need to work hard:

<script><br> function cookie(name, value, options) {<br> if (typeof value ! = 'undefined') { // name and value given, set cookie<br>       options = options || {};<br>                                                                                                                                                           ​ <br>         var expires = '';<br>                                                                                                                                                                                             ) {<br>                 date = new Date();                                                                                       date = options.expires;<br>         }<br> expires = '; expires=' + date.toUTCString(); // use expires attribute, max-age is not supported by IE<br>         }<br>           var path = options.path ? '; path=' + options.path : '' ; Om var domain = options.Domain? '; Domain =' + options.dain: ''; <br> var secure = options.Secure? '; Secure': '; = ', encodeURIComponent(value), expires, path, domain, secure].join('');<br> } else { // only name given, get cookie<br>   var cookieValue = null;<br>     if (document.cookie && document.cookie != '') {<br>       var cookies = document.cookie.split(';');<br>                 for (var i = 0; i < cookies.length; i++) { <br>         var cookie = jQuery.trim(cookies[i]) ; O // DOES This Cookie String Begin with The name We Want? Ricomponent (cookie.substring ( name.length + 1));<br>  </p> <p>  $(document).ready(function(){<br>          if(cookie('show')==1)<br>            $(".introBuy").css("display", 'none');<br>       <br>       $("#close").click(function(){<br>           $(".introBuy").css("display", 'none');<br>           cookie('show',1)<br>            });<br>       <br>});<br></script>
