Date field on catalog item can not be prior to the current day's date

[Cupcake]

I have a date field where I want to ensure that the date selected from the date variable is not greater than the current days date. I have the following code for another date field that has to be 5 days out. Not very good with the date thing yet, so 1) should i have something like a (-1) in my dateMS portion of the script. And 2) will it render an error if the customer tries to select a date in the past or should I include some code that has an alert type of box stating something like "Please select a future date"......

var today = new Date();

var dateMS = today.getTime();

dateMS = dateMS + (5*24*60*60*1000);

var newDT = new Date();

newDT.setTime(dateMS);

g_form.setValue('ftr_needed_by',formatDate(newDT,g_user_date_format));

Thank you,

Karen

Thank you I created an onChange catalog client script and I am receiving the following error. I tried adding a ), but didn't get any better.

Karen,

there was a pb with the row 17 and 19.

Here is the corrected script :

function verifyDates() {
   var dReqStart = new GlideDateTime();
   dReqStart.setDisplayValue(current.u_req_start_date);
   var dReqEnd = new GlideDateTime();
   dReqEnd.setDisplayValue(current.u_req_end_date);
   var today = new GlideDateTime();
   today.setDisplayValue(gs.now());
   if ((dReqStart.getNumericValue() - today.getNumericValue())/(1000*60*60*24) < 0) {
   gs.addErrorMessage("Request Start Date cannot begin before today.");
   current.setAbortAction(true);
   } else if ((dReqEnd.getNumericValue() - dReqStart.getNumericValue())/(1000*60*60*24) < 0) {
   gs.addErrorMessage("Request End Date cannot come before Request Start Date.");
   current.setAbortAction(true);
   }

}

Kind regards,

ZA

Dear AKb,

        Sorry to be a bother but this is still not working. I changed the script and I receive the following error. Because of the error about the gs not being used in client scripts, I even tried changing that to alert and still no good.

Hi Karen, could you please try this structure:

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

  if (isLoading || newValue == '') {

        return;

  }

// your logic goes here...

}

And please use g_form.getValue and g_form.setValue functions accordingly.

This is a wiki you can refer too Useful Catalog Scripts - ServiceNow Wiki

Hope this will help you.

This is a script that i have used, may be modify accordingly to your purpose.

Hope this will help you.

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

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

          return;

    }

    if (!isLoading) {  

          if(newValue != '') {  

                //current date  

                var currentDateObj = new Date();  

                var currentDateStr = formatDate(currentDateObj, g_user_date_format);  

                var currentDateNum = getDateFromFormat(currentDateStr, g_user_date_format);  

                //get delivery_date

                var startDateStr = g_form.getValue('estimated_delivery_date');  

                var startDateNum = getDateFromFormat(startDateStr, g_user_date_format);                    

                if (startDateNum <= 0){  

                      alert('Please use the calendar icon to select a date.');  

                      g_form.setValue('estimated_delivery_date', '');  

                } else if (startDateNum < currentDateNum) {  

                      alert('You cannot select a date in the past.');  

                      g_form.setValue('estimated_delivery_date', '');  

                }

          }  

    }  

}
