How to make fields read only when future date is selected in a Date field

[varunkumar1]

Hi,

I have 3 fields on a form as below

Date field and 2 string fields.

When Date selected is tomorrow's date, then other two string fields should be made as read only.

Please let me know how can this be done.

You could add an onChange script to the date field like this:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue == '') {
   return;
   }

   var date_field = new Date(getDateFromFormat(newValue, g_user_date_time_format));
   var current_date = new Date(new Date().getTime());
   if(current_date < date_field){
   g_form.setReadOnly('field_one',true);
   g_form.setReadOnly('field_two',true);
   }
}

I tried this out of curiosity and i found that below line is returning me epoch time, that is 1 jan 70.

var date_field = new Date(getDateFromFormat(newValue, g_user_date_time_format));

The getDateFromFormat should return epoch time.   You use it because a user may have modified their date format preferences to get a 'sanitized' date in a common format.   When wrapped in a new Date object, it should be a standard client date object.   This makes it safe for comparison no matter what the user's date time preferences are.   There is a more complete explanation here (https://jamesfarrer.com/?id=319😞
