Hi,

I have a field "Start Date" date type = "Notice period" field Date type + "Duration in month" decimal type

its working and setting the date correct if the Duration in month i'm adding is whole "for example 3 " but if " 3.5 " it consider it as 3 months and setting wrong

any suggestion?

function SetStartDate() 
{
   debugger;
   var Notice = Xrm.Page.getAttribute("new_notice").getValue();
   var Duration=Xrm.Page.getAttribute("new_durationinmonth").getValue();

   if(Notice != null && Notice != "" &&Duration != null && Duration != "" )
   {
 
     Notice.setMonth(Notice.getMonth() + Duration); 

   Xrm.Page.getAttribute("new_startdate").setValue(Notice);
     Xrm.Page.getAttribute("new_startdate").setSubmitMode("always");

     
   }

}

RE: adding a decimal number for a date

So just use the months part:

var numberOfMonths = Math.floor(duration);

Notice.setMonth(Notice.getMonth() + numberOfMonths);

This will only add 3 months instead of 3.5

If you need to add 3.5, you will need to convert the 0.5 to 15 days as previously mentioned.

Hope this helps.

If you don't have days, 3.5 months is correctly going to resolve to 1/July/2018. Otherwise, Aric correctly gives you how you would need to parse that out to 16/July/2018.

RE: adding a decimal number for a date

But I don't have days ! the duration is in month so when duration = 3 and notice 1/may/2018 --> start date= 1/july/2018 which is correct, but if duration = 3.5 its considered as the same case

RE: adding a decimal number for a date

Hi Faith,

You should consider changing your code so that it adds days to the months.

For example, if you value is 3.5, you should use setMonth(month, days).

Notice.setMonth(Notice.getMonth() + Duration);

You can also use the Math.floor to get the number of days:

var numberOfMonths = Math.floor(duration);

var numberOfDays = (duration - Math.floor(duration)) * 30;

Notice.setMonth(Notice.getMonth() + numberOfMonths, numberOfDays);

Check your options here:

Hope this helps.

You're going to have to parse the decimal into a number of days yourself and add the days to the date.
