How do you prevent users from selecting a date in the past?

[ngriffiths]

We have a requirement to capture an effective date on a record producer and I have currently built a Date/Time variable that will allow us to do so.   Now with that being said, the rest of the requirement is to prevent users from selecting a date/time in the past.

For example, today is 1/14/2016, therefore the user should NOT be able to select 1/10/2016 as a possible date.  

Essentially, we want any date leading up to the current date/time to be read only.   Is this a possibility and if so how do we go about it?   I am not a programmer, so if there is a script involved, which I am positive there is, it would be much appreciated if you can help with that as well.

Thanks!

did you add the g_form at the start of that line?

[ngriffiths]

Yep.   This is the whole script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

      if (isLoading || newValue == '') {

              return;

      }

      var dt = getDateFromFormat(newValue, g_user_date_time_format);

      var rightNow = new Date();

      if (dt < rightNow) {

              alert('The date value cannot be before the current date and time. Please correct.');

              g_form.clearValue(effective_date);

              g_form.flash("effective_date", "#FFFF00", 5);

      }

}

g_form.clearValue('effective_date');

i think you missed the ''

So that worked for clearing the form, but the flash will not work.

I just tried

g_form.flash("effective_date", yellow, 2);

and that still didn't work

According to the SNow wiki article, the flash method is not supported by the Service Catalog.   Thus that is prob why no matter what I am changing it to, it still is failing.   Not a huge deal, it would have been nice to have the field flash a color, but the field is mandatory and clearing the value will force them to select a date before they can submit the request.

I very much appreciate all your help!

Here is the final script for anyone who is curious:

Catalog Client Script

Applies to: A Catalog Item

Type: onChange

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

      if (isLoading || newValue == '') {

              return;

      }

      var dt = getDateFromFormat(newValue, g_user_date_time_format);

      var rightNow = new Date();

      if (dt < rightNow) {

              alert('The date value cannot be before the current date and time. Please correct.');

              g_form.clearValue("effective_date");

      }

}
