[JavaScript] bei klick var x in ein textfeld setzen

<!-- The following empty element is the container for the calendar.
It has the ID that you defined at step 1 (“Type”).
When “Calendar.setup” is called below, the calendar will be generated
in this element. Feel free to position it the way you want
using CSS. You will normally want this to be a floating element
which is why we generated one having the style “float: right”. -->

<div style="float: right; margin: 0 0 1em 1em" id="calendar"></div>

<!-- The following JavaScript code defines a function that will
get called each time the user modifies the date inside the calendar.
To make sure that a date was actually clicked, we check the
cal.dateClicked variable. If a date wasn't clicked this will be
“false” and it usually means that the date was modified using the
month or year navigation buttons, or that only the time got modified. -->

 <script type="text/javascript">//<![CDATA[
 function flatCalendarCallback(cal) {
 if (cal.dateClicked) {
 var url = "http://www.mydomain.com/" + cal.date.print("%Y/%m/%d/");
 alert("Jumping to: “" + url + "” (not really).");
 // uncomment the following line to actually jump:
 // window.location = url;
 }
 };
