Cookies with ExtJS

In this case we are going to use a cookie to store the username logged into de system in case the checkbox “Recordar usario” is checked.

To set the cookie we are going to use this function called when clicked the button “Entrar”, and after success to log :

In this function the cookie is created with the id 'accessCookie' and with the username 'user', and also with an expiration delay of 30 days. In case the user select not to remember the username then the delay is set for one milisec which causes to delete the cookie.

To load the user stored in the cookie we use the afterrender event for the login view, which tries to read the cookie and if it exists then the username is loaded into the user name field, and the  “Recordar usuario” check box is checked.
