How to restrict date variable to only allow selecting a date that is 5 days from today and onwards?

Hi,

Please help me script.  I have date field named startdate, but I need for users not to be able to select any date before 5 days from today.

Thanks!

Hii,

Refer the below link and you should be able to get the script

Hi,

I tried to make use of what I think is the answer, but without luck.  It doesn't work.

The bold characters below are the only ones I've modified. 

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
if (isLoading || newValue === '') {
return;
}
var cdt = newValue; //The date field
var dttype = 'day'; //this can be day, hour, minute, second. By default it will return seconds.

/******** This Checks whether the selected date is in the Past or Not************************/
var ajax = new GlideAjax('ClientDateTimeUtils_New');
ajax.addParam('sysparm_name','getNowDateTimeDiff');
ajax.addParam('sysparm_fdt', cdt);
ajax.addParam('sysparm_difftype', dttype);
ajax.getXML(doSomething);

function doSomething(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
if(answer<-5){
alert("Start date can only be after 5 days from today.");
g_form.clearValue('startdate'); // Pass the variable name here
g_form.setMandatory('startdate', true);
}
}}

I have also created the script include, copied everything into it. Doesn't work.

Here's my OnChange Client Script that calls the same Script Includes (with the original name however) requiring that a due date is greater than 5 days out (note it is in seconds):

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
 
 
  var cdt = g_form.getValue('due_date'); //First Date/Time field 
 
  var ajax = new GlideAjax('ClientDateTimeUtils'); 
  ajax.addParam('sysparm_name','getNowDateTimeDiff'); 
  ajax.addParam('sysparm_fdt', cdt); 
  ajax.getXML(doSomething); 
 
  function doSomething(response){ 
  var answer = response.responseXML.documentElement.getAttribute("answer"); 
  //5 days out
	  if (answer < 431000)
  {
  alert('The lead time to process this request is 5 days.' + '\n' +  'If this is an urgent request please contact the Service Desk for assistance escalating this request.');
	  //alert('The date value cannot be before 5 days into the future. Please correct.');
  //g_form.clearValue("due_date");
  }
  
  }
}
