Here is a start, using js-cookie and JavaScript Date object.
jsFiddle link
Basically it:
- gets client time
- checks if first ever visit to the site
- if first visit, it sets a final expiration datetime cookie 3 days from now
- and also sets expired cookie to false
- it not first visit, it checks if client time is greater than final expiration cookie time
- if it is, it removes all cookies and sets expired cookie to true
- if it's not, it checks for morning, afternoon and night cookies depending on the hour of the day
- if it is the first visit at a particular part of the day, it will show a popup
- and also change greeting text depending on time of day, eg:
Not very elegant or concise, but hopefully demonstrated well enough for you to make something.
When testing, if you want to view all cookies that have been set, you can use:
Cookies.get();
and to remove cookies, you can use:
Cookies.remove("cookie_name_here");
morning, afternoon and night are defined as:
0400 to 1200
1200 to 1700
1700 to 0400
but you can change them as you like.
