Problems encountered when using Jquery.cookie.js

jquery.cookie.jsBasic operations

$.cookie("key","value"); //写入
$.cookie("key","update value");//修改
$.cookie("key",null);//删除

If $.cookie("key","value") writes the cookie, but does not set the path, the default path will be used when creating the cookie for you. The path of the current operation page

For example:

Write a $.cookie("user","zhangsan"); on the http://localhost:8001/user/list page; pass When viewing the developer tool, the path is /user/list

Write a $.cookie("user","zhangsan1") on the http://localhost:8001/pay/list page; through the developer tool When viewing, the path is /pay/list

. In this way, when you get $.cookie("user") on other pages; you will always get the value zhangsan written for the first time, and the modification will not be successful. , the same is true for deletion

So it is best to specify the path when writing cookies, such as: $.cookie("key","value",{path:"/"});

In this way, no matter which page you are on, you can modify, update, or delete the cookie value of the corresponding key
