How to restrict past date selection.

[devr]

Hi All,

I found below details from one of the thread to restrict past date selection in catalog item however the same is not working in Normal table form, please suggest how to achieve the same in normal table forms (reference- https://community.servicenow.com/thread/159148😞

____________________________________________________________________________

OnChange Client Script : field name : date_time
Script :
function onChange(control, oldValue, newValue, isLoading)
{
if(isLoading){ return; }
if(newValue != ''){
var ga = new GlideAjax('CheckDate');
ga.addParam('sysparm_name', 'chkCatDate');
ga.addParam('sysparm_date',g_form.getValue('date_time'));
ga.getXML(DatParse);
}
function DatParse(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
if(answer == 'false'){
alert("Date cannot exist in past.");
g_form.setValue('date_time', ''); // Empty the variable.
}}}

___________________________________________________________________________

Now write a script include as follows :-

Name : CheckDate
Client callable : true
Script :
var CheckDate = Class.create();
CheckDate.prototype = Object.extendsObject(AbstractAjaxProcessor, {
chkCatDate : function() {

var start = this.getParameter('sysparm_date');
var currDay = gs.now();
if(start < currDay){
return false;
}
else
{ return true; } } });

var date1 = new Date(g_form.getValue('start_date');

var date2 = new Date();

if(date1 <date2){

alert("Add future day");

}

Concise and succinct

A note - missing a )   on the first line.

var date1 = new Date(g_form.getValue('start_date');

var date2 = new Date();

if(date1 <date2){

alert("Add future day");

}

return false;

It should work, but if not, try this (working for me on both catalog item and on normal tables and forms.

u_time1 is the field I am checking.

Client script:

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

   //Type appropriate comment here, and begin script below
       var ga = new GlideAjax("NowDateCalc");
ga.addParam("sysparm_name", "getNow");
ga.getXML(getDate);
}

function getDate(response) {
var my_date = g_form.getValue('u_time1');
var rightNow = response.responseXML.documentElement.getAttribute("answer");

if (my_date < rightNow) {
alert("Date needed by cannot be earlier than today.");
g_form.setValue('date_needed', '');
}
}

Script include:

Name: NowDateCalc

Client callable: yes

var NowDateCalc = Class.create();
NowDateCalc.prototype = Object.extendsObject(AbstractAjaxProcessor,{

getNow : function() {
return gs.now();

},
       type: 'NowDateCalc'
});
