Grails make one g:datePicker depend on other g:datePicker -

imagine have index.gsp 2 dates: starting day , ending day.

when user picks starting day, how can calculate + 2 months in ending day?

i know in controller have like:

use (timecategory) {     c = new date() + 2.month } 

but how best way change ending day in gsp? remotefunction?

edit: yes worked, thank lukelazarovic.

like said thing needed change last line, changed to: $("#myid_month").val(month+3);

    function datewaschanged(){     ....          $("#myid_month").val(month+3);     } 

edit2: needed increment year, reason strings remember do: myinteger = parseint(mystring);

i assume want on client - without reloading page +2 months date set end date datepicker.

that means have using javascript or javascript-based framework (jquery).

you can go along solution suggested in question: get date value grails datepicker change set value of end datepicker on last line of function datewaschanged this:

$("#enddatepickerid").datpicker("setdate", date);
