var x =  document.cookie;

You can delete a cookie variable by setting its value as nothing, as shown below.

$.cookie("test", "hello");

You can also set multiple cookie variables in a single command by including a JS object of key-value pairs as shown below.

$.cookie("test", "hello", {expires : 10, domain  : ''});
