Jquery. cookie function method that is compatible with IE to obtain and set cookies _ jquery-js tutorial

When using IE for testing, we found the common in Discuz. the getcookie and setcookie methods in js do not work under IE, so jquery is available. cookie. the origin of js. If you are interested, refer Preface

In the development process, because we have been in touch with Discuz before, we can directly use its common. the getcookie and setcookie methods in js are used for subsequent tests. When I find that these two methods do not work in IE, I will ask my colleagues, in this way, jquery is available. cookie. the origin of js files contains very few codes. I will paste them below to facilitate future use and research.
