Jquery cookie usage Problems

1. Add cookie. js

2. Set cookie

 
$. Cookie ('username', '', {expires:-1}); // delete a cookie
$. Cookie ('username', username, {path :'/'});
Alert ($. Cookie ('username '));

 

Try not to use VaR cookie_name = "username" here; in this form, set the cookie name. If so, you can obtain the name of cookie_name on this page.

However, if the cookie is to be used on other pages, it may be a problem. The cookie cookie_name may not be obtained,

Take the cookie on another page:

 If ($. Cookie ("username ")){
$ (". Style6" ).html ("Welcome:" + $. Cookie ("username "));

 

 

We recommend that you do not set the cookie name in the form of VaR cookie_name = "username". This page can be used on other pages.

The cookie name may not be obtained.
