Cookie operation plug-in implemented by jquery:

Although cookies are fixed, they are still very useful in handling certain problems. We will not list them here. Here we provide a jquery-implemented cookie operation plug-in with comprehensive functions, the Code is as follows:

jQuery.cookie=function(name, value, options){  if(typeof value != 'undefined'){     options=options||{};    if(value === null){      value='';      options.expires=-1;    }    var expires='';    if(options.expires&&(typeof options.expires=='number'||options.expires.toUTCString)){      var date;      if(typeof options.expires=='number'){        date=new Date();        date.setTime(date.getTime()+(options.expires * 24 * 60 * 60 * 1000));      }       else{         date = options.expires;      }      expires= '; expires=' + date.toUTCString();     }    var path = options.path ? '; path=' + (options.path) : '';    var domain = options.domain ? '; domain=' + (options.domain) : '';    var secure = options.secure ? '; secure' : '';    document.cookie = [name, '=', encodeURIComponent(value), expires, path, domain, secure].join('');  }   else{    var cookieValue = null;    if(document.cookie && document.cookie != ''){      var cookies = document.cookie.split(';');      for (var i = 0; i < cookies.length; i++){        var cookie = jQuery.trim(cookies[i]);        if (cookie.substring(0, name.length + 1) == (name + '=')){          cookieValue = decodeURIComponent(cookie.substring(name.length + 1));          break;        }      }    }    return cookieValue;  }}

The above is a powerful jquery plug-in for cookie operations.

The plug-in instructions are as follows:

1. jQuery. cookie ("mycookie") to obtain the cookie.

2. jQuery. cookie ("mycookie", "cookievalue") to set the cookie value.

3. jQuery. cookie ("mycookie", "cookievalue", {expires: 3, path: '/', domain: 'jquery. com ', secure: true}), create a cookie, and set the cookie expiration time, path, domain name, and so on.

4. jQuery. cookie ("mycookie", null), delete a cookie.
