Events across a Range of Days

Section 3.4.3

You may have a need to write an event that spans two months or several months. The reoccuring code already presented is inadequate for such events.

Instead, you need to turn to a concept called a "ymd" date. Ymd stands for year-month-day. It means that instead of writing a date like 01/01/2010, you write it year first, follwed by the month and finally the day. The same date becomes 2010-01-01. Last, we can remove the dashes to have the number 20100101.

When you write dates in this ymd format, you can do numeric comparisons. Like 12/31/2008 is less than 01/01/2009 ( 20081231 < 20090101) or 5/1/2009 is less than 9/20/2009 (20090501 < 20090920).

You change the date being rendered to the ymd numeric date in the spspcevt.js. The date passed to the scspcevt.js is the "dte" variable. To translate this javascript date into a ymd numeric value, you can call a method on date values. This method is added by the Scriptcalendar engine. Please see the the code below.

Now you can use this ymd numeric to your advantage. Imagine you need an event from 5/1/2009 through 9/20/2009. We can translate these values in ymd numeric values. They become 20090501 and 20090920 respectively. To check if we are in the range, we just compare the numeric values.
