<div id="flatcal" style="float: right"></div>
<script type="text/javascript">
function getDateText(date, d) {
var inf = dateInfo[date.print("%Y%m%d")];
if (!inf) {
return d + "<div class='inf'> </div>";
} else {
return d + "<div class='inf'>" + inf + "</div>";
}
};
function flatCallback(cal) {
if (cal.dateClicked) {
// do something here
window.status = "Selected: " + cal.date;
var inf = dateInfo[cal.date.print("%Y%m%d")];
if (inf) {
window.status += ". Additional info: " + inf;
}
}
};
Calendar.setup({
flat: "flatcal",
dateText: getDateText,
flatCallback: flatCallback
});
</script>
<p>The idea is simple:</p>
<ol>
<li>
<p>Define a callback that takes two parameters like this:</p>
<pre>function getDateText(date, d)</pre>
<p>
This function will receive the date object as the first
parameter and the current date number (1..31) as the second (you
can get it as well by calling date.getDate() but since it's very
probably useful I thought I'd pass it too so that we can avoid a
function call).
</p>
<p>
This function <em>must</em> return the text to be inserted in
the cell of the passed date. That is, one should at least
"return d;".
</p>
</li>
<li>
Pass the above function as the "dateText" parameter to
Calendar.setup.
</li>
</ol>
<p>
The function could simply look like:
</p>
<pre
> function getDateText(date, d) {
if (d == 12) {
return "12th";
} else if (d == 13) {
return "bad luck";
} /* ... etc ... */
}</pre>
<p>
but it's easy to imagine that this approach sucks. For a better
way, see the source of this page and note the usage of an externally
defined "dateText" object which maps "date" to "date info", also
taking into account the year and month. This object can be easily
generated from a database, and the getDateText function becomes
extremely simple (and static).
</p>

Cheers!
