As noted one cannot prevent the saving of the file. To do so would prevent a user from saving a partially completed file/form and then coming back to it later. This creates a very bad user experience. One can mark a form as incomplete until all the fields are completed. This can be done using a read only field to hold the message and only clear that form when all the fields have been completed. You will have to write a script that check for completion of all of the fields which will fill-in or clear that field. ... View more

There are other methods available to the date object beside "getTime". I would look at using the "getFullyear", "getMonth", and "getDate" methods to compute the full number of years, months, and the number of the day within the month. You then only need to get the number of days in the birth month and you should have all the information for your computation. It would not hurt to add some comments to your code to explain what it is doing. Unless you are a banker using bank formulas a month does not always have 30 days. ... View more

With the following fields: DateWorked with a format of d-mmm-yyyy StartTime with a format of h:MM tt EndTime wit a format of h:MM tt Your custom calculation script could be: event.value = ""; // clear result; var cDateFormat = "d-mmm-yyyy"; // format for date field; var cTimeFormat = "h:MM tt"; // format for time fields; var cDateWorked = this.getField("DateWorked").valueAsString; // get date worked; var cStartTime = this.getField("StartTime").valueAsString; // get start time; var cEndTime = this.getField("EndTime").valueAsString; // get end time; if(cDateWorked != "" && cStartTime != "" && cEndTime != "") { // compute worked time only if we have data; var oStartDateTime = util.scand(cDateFormat + " " + cTimeFormat, cDateWorked + " " + cStartTime); // start date time as Date object; var oEndDateTime = util.scand(cDateFormat + " " + cTimeFormat, cDateWorked + " " + cEndTime); // end date time as Date objec; if(oStartDateTime != null && oEndDateTime != null){ // compute only if we have valid date and time combination; // the time difference is reported in minutes; event.value = Math.floor((oEndDateTime.getTime() - oStartDateTime.getTime()) / (1000 * 60)); // compute worked time as minutes; // displayed vlaue is set in the custom format script, so the total of all time can be computed in minutes; } } Your custom format script could be: if(event.value != "") { // display format as hours and minutes; event.value = util.printf("%,101d:%,102d", Math.floor(event.value / 60), (event.value % 60)); } This approach for the form will allow one to accumulate the total time worked if there are multiple days included to be computed in minutes and then use the custom format to format the displayed result. ...

If you are in a location that observes Daylight Savings Time and your time sheet will record time that includes the switch over time, you will also need the date for the computation. This question has asked many times and there have been many posted examples. The process is 1. convert the start date and time to a JavaScript Date object. 2. get the milliseconds from the Epoch date for the start and end values. 3. convert the milliseconds to minutes. 4. compute the difference in minutes. 5 reformat the result into hours and minutes and fill in the result value. Note that the elapsed time value may appear to be the same as the time format, but the day format only allows a maximum value of 23 hours and 59 minutes but a weekly time sheet for a full time employee will easily exceed this value. ...

Page number property of a field.

This example gets the number of radio buttons in a radio button field.    var f = this.getField("myRadio");    if ( typeof f.page == "object" )       console.println("There are " + f.page.length          + " radios in this field."); ...
