The "today" subcookie stores a date string, which should be converted to a <code>Date</code> object upon retrieval; the third argument of <code>getSub()</code> is specified as a custom function that will convert the returned value into a <code>Date</code> object. The "count" subcookie contains a number and is converted to an actual JavaScript number by passing in the native <code>Number</code> function. If any of these subcookies don't exist, <code>getSub()</code> returns <code>null</code> (this should be the case the first time you run the example). The retrieved values are output in the logger.</p> <p>After that, new values are assigned to the various subcookies:</p> <textarea name="code" class="JScript" cols="60" rows="1"> Y.Cookie.setSub("example", "name", "Yahoo!"); Y.Cookie.setSub("example", "today", (new Date()).toString()); Y.Cookie.setSub("example", "count", Math.round(Math.random() * 30)); </textarea> <p>The "name" subcookie is set to "Yahoo!", the "today" subcookie is set to the value of a new <code>Date</code> 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.</p> </div> <div class="yui-u sidebar"> <div id="examples" class="mod box4"> <div class="hd"> <h4> Cookie Examples:</h4> </div> <div class="bd"> <ul> <li><a href='../cookie/cookie-simple-example.html'>Simple Cookie Example</a></li><li><a href='../cookie/cookie-advanced-example.html'>Advanced Cookie Example</a></li><li class='selected'><a href='../cookie/cookie-subcookie-example.html'>Subcookie Example</a></li> </ul> </div> </div> <div class="mod box4"> <div class="hd"> <h4>More Cookie Resources:</h4> </div> <div class="bd"> <ul> <!-- <li><a href="http://developer.yahoo.com/yui/cookie/">User's Guide</a> (external)</li> --> <li><a href="../../api/module_cookie.html">API Documentation</a></li> </ul> </div> </div> </div> </div> </div> </div> <div class="yui-b toc3" id="tocWrapper"> <!-- TABLE OF CONTENTS --> <div id="toc"> <ul> <li class="sect first">YUI 3.x Project</li><li class="item"><a title="The Yahoo!
