Date validation in catalog client script?

[gokulraj]

Hello team,

I have a requirement in change request if user selects the past planned date it should have to popup an alert message to choose the current or future date.

It is working fine for almost all users with my old script,

it fails when user choose the date format like mm/dd/yy in their profile 

my new script

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
var startDateStr = g_form.getValue('start_date');
if(moment) {
var dateFormat = g_user_date_time_format;
var currentDate = new moment(g_form.getValue('start_date'),dateFormat);
alert('currentDate**' + currentDate + 'startDateStr**' +startDateStr);
if(startDateStr <= currentDate) {
alert('"Planned Start Date" must be set to a current or future time');
g_form.setValue('start_date', '');

}
}

}

Old script

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Type appropriate comment here, and begin script below
var currentTime = '';
var time = new GlideAjax('DateTime');
time.addParam('sysparm_name', 'getNowDateTime');
time.getXML(
function () {
currentTime = time.getAnswer();
if (newValue <= currentTime){
alert('"Planned Start Date" must be set to a current or future time');
g_form.setValue('start_date','');
}
}

);

}

my issue is my new script not able to identify the current date , it shows like below,

How to achieve this?

Hi,

Try this script:

Client Script:

function onChange(control, oldValue, newValue, isLoading) {
if (isLoading || newValue == '') {
return;
}
//Type appropriate comment here, and begin script below
var currentTime = '';
var time = new GlideAjax('DateTime');
time.addParam('sysparm_name', 'getNowDateTime');
time.addparam('sysparm_time',newValue);
time.getXML(
function () {

currentTime = time.getAnswer();
alert('newValue**' + newValue + 'currentTime**'+currentTime );
if (currentTime == 'true'){
alert('"Planned Start Date" must be set to a current or future time');
g_form.setValue('start_date','');
}
}

);

}

Script Include:
var DateTime = Class.create();
DateTime.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getNowDateTime: function () {
var firstDT = this.getParameter('sysparm_time'); //First Date-Time Field
var diff = gs.dateDiff(firstDT, gs.nowDateTime(), true);
var answer = '';
if (diff <= 0){
answer = 'true';
}
else {
answer = 'false';
}
return answer;
},

getNowRelativeDateTime: function () {

var relativeDateTime = new GlideDateTime(gs.nowDateTime());
relativeDateTime.addSeconds(300);
return relativeDateTime;
},

getNowRelativeFutureDateTime: function () {
var relativeDateTime = new GlideDateTime(gs.nowDateTime());
relativeDateTime.addSeconds(-300);
return relativeDateTime;
}
});

Thanks,
