Hi,

You can try below code:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var date1 = new Date(g_form.getValue('date_field'));
var date2 = new Date();
var timeDiff = Math.abs(date2.getTime() - date1.getTime());
var diffDays = Math.ceil(timeDiff / (1000 * 3600 * 24));

if(diffDays != 7) {
alert("Error Message");
g_form.clearValue('date_field');
return false;
}
else
return true;
//Type appropriate comment here, and begin script below
}

Thanks,

hi,

try this code will work irrespective of the date format:

Client Script:-

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

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

                  return;    

           }   

            //Type appropriate comment here, and begin script below    

    var start_date = g_form.getValue('start_date');    

    var ga = new GlideAjax("calcDate"); //name of script include    

    ga.addParam("sysparm_name", "getDate"); //name of function in script include    

     ga.addParam("sysparm_start", start_date); //send start value to script    

      ga.addParam("sysparm_end", newValue);

      ga.getXML(checkDate); //callback function    

}    

Script Include :

      function checkDate(response) {          

          var answer = response.responseXML.documentElement.getAttribute("answer"); //the response from the script    

if (answer > 7) { //if the date received is more than 7 days from the start date    

    alert("End date cannot be later than 7 days after start date.");    

    g_form.setValue('end_date', ''); //remove value from end date field    

      return false;    

      }    

  }

script include code-

var calcDate = Class.create();      

  calcDate.prototype = Object.extendsObject(AbstractAjaxProcessor,{      

    getDate : function() {      

      var startDT = new GlideDate();

    startDT.setDisplayValue(this.getParameter('sysparm_start'));

    var endDT = new GlideDate();

    endDT.setDisplayValue(this.getParameter('sysparm_end'));

    var duration = new GlideDuration();

  duration= GlideDate.subtract(startDT, endDT);

  return duration.getDayPart();  

    },      

    type: 'calcDate'      

});

Try as well this code:-

var today = new Date();

var dateMS = today.getTime();

dateMS = dateMS + (7*24*60*60*1000);

var newDT = new Date();

newDT.setTime(dateMS);

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