Cookie: Subcookie Example
+ +This example shows how to get and set subcookies as well as using conversion functions when retrieving subcookie values.
Subcookie Example
+The first three lines attempt to read the values stored in subcookies of the "example" cookie:
+
var name = Y.Cookie.getSub("example", "name"); +var today = Y.Cookie.getSub("example", "today", function(value){ + return new Date(value); +}); +var count = Y.Cookie.getSub("example", "count", Number);
The "name" subcookie stores a string so it is retrieved without specifying a third argument. The "today"
+subcookie stores a date string, which should be converted to a Date object upon retrieval; the third argument
+of getSub() is specified as a custom function that will convert the returned value into a Date object.
+The "count" subcookie contains a number and is converted to an actual JavaScript number by passing in the native
+Number function. If any of these subcookies don't exist, getSub() returns null (this should
+be the case the first time you run the example). The retrieved values are output in the logger.
After that, new values are assigned to the various subcookies:
+
Y.Cookie.setSub("example", "name", "Yahoo!"); +Y.Cookie.setSub("example", "today", (new Date()).toString()); +Y.Cookie.setSub("example", "count", Math.round(Math.random() * 30));
The "name" subcookie is set to "Yahoo!", the "today" subcookie is set to the value
+of a new Date object, outputting its string representation, and the "count" subcookie is filled
+with a random number. The next time you run the example, the subcookies should have these values.
