I have a PDF form which users currently have to manually enter dates in each day of the week. I would like to make it so a user enters a date in the first box (date1) and the rest of the fields are populated with the next days so that
date1 = 02/22/2009 (entered manually)
date2 = date1 + 1 day (calculated)
date3 = date1 + 2 days (calculated)
date4 = date1 + 3 days (calculated)
and so on. Can anybody tell me how to accomplish this?
Thanks.
var sNow = this.getField('date1').value;// see if there is a value for computationif(sNow == ''){// clear other date fields if field is emptythis.resetForm(['date2', 'date3', 'date4']);} else {// computation for none empty field// define some variablesvar mDay = 1000 * 60 * 60 * 24; //one day in millisecondsvar oDate; // date time object for datevar fDate; // value of date time objectvar fNext; // value for next date var oNext; // date time object for next datevar sNext; // formatted string for next date// convert date to date time objectoDate = util.scand('mm/dd/yyyy', sNow);fDate = oDate.valueOf(); // loop through days to addfor(i = 1; i <4; i++) {// add i days to datefNext = fDate + (mDay * i);// convert next day to date time objectoNext = new Date(fNext);// convert next day date time object to stringsNext = util.printd('mm/dd/yyyy', oNext);// assign next date string to date fieldthis.getField('date' + (i+1)).value = sNext;} // end day loop } // end not empty
event.value = ''; // clear result by default// see if we have datavar fFirstDate = this.getField("date1").value;if(fFirstDate.length) {var oneDay = 24 * 60 * 60 * 1000; // one day in millisecondsvar oFirstMilli = util.scand("mm/dd/yyyy",fFirstDate); // base date as time objectvar fSecondMillis = fFirstMilli.valueOf() + oneDay; // add one day milliseconds to value of date time objectvar fSecondDate = new Date(fSecondMillis); // convert milliseconds to date time objectevent.value = util.printd("mm/dd/yyyy", fSecondDate) // format date time object}
This can be done with JavaScript . It's a bit of ocde and field naming is important for it to work, so maybe a bit complex for a complete solution in a forum setting like this. This is hours of work for someone who really knows JS already.
Here is an article on working with dates and times in Acrobat using JavaScript that should get you started. Whne you have some code and a specific problem then this is a good place to get pinpoint type help.
