jQuery: Read all domain cookies if you don't know their names

Question

I'm using the jQuery cookie plugin to read/write/delete cookies. I'm using cookies to store points on a graph that the user plotted on top of a canvas. I'm allowing the user to store the plotted points along with a name in the cookie, I'm also listing the saved cookies so that they can redraw their saved points on the graph.

I was originally saving and reloading the points from cookies by naming each cookie with a sequential number $.cookie("_1"), $.cookie("_2"), etc and this worked. Problems start when user deletes a cookie and the sequential numbering breaks.

I would like to save the cookie using the name that the user gives to the plotted points, so basically saving cookies with arbitrary names. If I do this is it possible to read all domain cookies if I don't know their names?

Answer 1

You don't need jQuery for this. You can read all your cookies by accessing document.cookie and parsing accordingly.

See an example here.

Answer 2

I don't know about calling all domain cookies, but you could always store the cookie with a name you choose and then make the value of the cookie be "name,x,y" or something. Just an idea as an alternative to trying to pull all domain cookies.

EDIT:

Also, this cookies plugin wiki shows that you can easily get a filtered list of cookies. So you could throw on an identifier to the name of the cookie "mysite+name" and then use .slice to take it back off after you get your filtered list.
