Adding days to date field based on another date field (Default value)

[Tomer]

Hello experts,

I'm writing a short script for adding days to date field value based on another field (Record producer):

javascript:var d = new GlideDate(current.u_start_day.getDisplayValue()); d.addDays(182); d.getDisplayValue();

need to add half an year for starting date.

this piece of code worked without my field:

javascript:var d = new GlideDate(current.u_start_day.getDisplayValue()); d.addDays(182); d.getDisplayValue();

but then it's adding days from today (I need to take it from the date on : 'u_start_day' field).

any suggestions?

Thanks,

Tomer.

try 

var d = new GlideDate();d.setValue(current.u_start_day.getDisplayValue()); d.addDays(182); d.getDisplayValue()

I had more issues with GlideDate and GlideDateTime when I wanted to set the date/time component on calling the class.

Thank you Jorn, it's still taking half an year from today

can I do client side?

thanks again.

So, you are wanting to add 182 days to Start Date to create Expiration Date?

If so, then this should do the trick:

var d = new GlideDate(current.u_start_day);
d.addDaysLocalTime(182);
current.u_expiration_date = d.getValue();

Hi Tomer , 

Try below script in business rule 

function onBefore(current, previous) {

    //This function will be automatically called when this rule is processed.

var gdt = gs.now();  

if(your condition){  

var gdt = new GlideDateTime();

gdt.addDaysLocalTime(number of days you want to add);

current.your second field name= gdt;

}    

}

Mark as correct if it is helpful 

Thanks ,
