JQuery simple cookie plug-in instance, jquerycookie instance

This example describes the jQuery plug-in for cookie operations. We will share this with you for your reference. The details are as follows:

jQuery.cookie = function(name, value, options) {  if (typeof value != 'undefined') { // name and value given, set cookie    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 call is also very convenient:

// Use the following method: // set the cookie key-Value Pair // $. cookie ('name', 'value'); // set the key-value pair, validity period, path, domain, and security of the cookie. // $. cookie ('name', 'value', {expires: 7, path: '/', domain: 'jquery. com ', secure: true}); // create a cookie, including the domain name in the validity period path. // read the cookie value // var account = $. cookie ('name'); // delete a cookie // example $. cookie ('name', null );
