jQuery cookie的公共方法封装和使用示例

本文实例讲述了jquery cookie的公共方法封装和使用。分享给大家供大家参考，具体如下：

common.js放入公共方法：

/**
 * 刷新cookie
 */
var cookiespath = '/';
var cookiestime = 3 / 24;
 
function refreshcookie() {
  var cookiedata = $.cookie();
  $.each(cookiedata, function (_key, _value) {
    $.cookie(_key, _value, {path: cookiespath, expires: cookiestime});
  });
}/**
 * 刷新cookie
 */
var cookiespath = '/';
var cookiestime = 3 / 24;
 
function refreshcookiecopy() {
  var cookiedata = _$.cookie();
  _$.each(cookiedata, function (_key, _value) {
    _$.cookie(_key, _value, {path: cookiespath, expires: cookiestime});
  });
}
 
/**
 * 设置cookie
 * @param key
 * @param value
 */
function setcookie(key, value) {
  refreshcookie();
  $.cookie(key, value, {path: cookiespath, expires: cookiestime});
}
/**
 * 设置_cookie
 * @param key
 * @param value
 */
function setcookiecopy(key, value) {
  refreshcookiecopy();
  _$.cookie(key, value, {path: cookiespath, expires: cookiestime});
}
 
/**
 * 设置cookie by time
 * @param key
 * @param value
 */
function setcookiebytime(key, value, time) {
  // refreshcookie();
  $.cookie(key, value, {path: cookiespath, expires: time});
}
 
/**
 * 获取cookie
 * @param key
 */
function getcookie(key) {
 
  return $.cookie(key);
}
 
/**
 * 删除cookie
 * @param key
 */
function deletecookie(key) {
  $.removecookie(key, {path: cookiespath});
}
 
/**
 * 清除cookie
 */
function clearcookie() {
  var cookiedata = $.cookie();
  $.each(cookiedata, function (key, value) {
    deletecookie(key);
  });
}
 
/**
 * 清除单个cookie
 */
function clearcookiesingle(name) {
  setcookie(name, "", -1);
}

如何使用：

function usecookie() {
  setcookie("name","gaopian");
  getcookie("name");
  deletecookie("name");
  clearcookie();
}
