getDateFromFormat not defined Error in Service Portal.

[Rosy]

I am getting getDateFromFormat not defined in Service Portal. I have two fields on my form start date and end date. We have also users in Europe where their date format is dd--mm--yyyy

So our requirement is start date should not allow past dates and users should only select a date at least two business days into the future.

And end date should not be less than the start date. Can someone help me with the code.

I have written the following code but i am getting getDateFromFormat not defined.

//this code is written on start date filed

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

var today = new Date();
//g_form.addInfoMessage("Today's date is" + today);

var ga = new GlideAjax('emeaDateRestrict');
ga.addParam('sysparm_name','dateRestrict');
ga.addParam('sysparm_date', g_form.getValue('date_start'));
ga.getXML(ajaxParse);

function ajaxParse(response){
var answer = response.responseXML.documentElement.getAttribute("answer");
//g_form.addInfoMessage(answer);//see the full JSON response
answer = JSON.parse(answer);

if((answer <86400 && answer>-86400) || answer==0){
g_form.clearValue('date_start');
g_form.addInfoMessage('Please select a valid date. Please select a date at least two business days into the future..');
}
else if(answer<-86400){
g_form.addInfoMessage('You may not select a previous date. Please select a date at least two business days into the future');
g_form.clearValue('date_start');
}
}
}

//glideajax

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

dateRestrict: function(){


var today = new Date();
var date = this.getParameter('sysparm_date');
var string = "G'day World";
var json = new JSON();
string = string + date + today;
var diffSeconds = gs.dateDiff(today, date, true);
//diffSeconds.addLocalTime(-1);



return json.encode(diffSeconds);


},
type: 'dr'
});

// i tried different code on end date variable after searching in the community, now i am getting getdatefromformart not defined error

// get user's date time display format

var isValidStart = getDateFromFormat(date_start, g_user_date_format);

var isValidEnd = getDateFromFormat(date_end, g_user_date_format);


if (end < start) {
alert("end must be after start");
g_form.setValue('u_end_date', '');
return 1;
}
else{
return 0;
}

I used below onChange script for end date validation. For Portal only.

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

	// Date format
	var dateFormat = g_user_date_format.toUpperCase();

	// Make sure end date is valid
	if (!(new moment(newValue, dateFormat).isValid())) {
		alert('The date entered is not a valid fromat, please use the date selector or enter using the format: ' + dateFormat);
		g_form.setValue('start_date', '');
		g_form.setValue('end_date', '');
	}
	else {
		// Variables used
		var startStr = g_form.getValue('start_date');
		var startDate = new moment(startStr);

		// Check that end is not in the past
		 if (startDate.diff(g_form.getValue('end_date'), 'days') >= 0) {
			// The end date cannot be the same or less than the start date
			alert('The end date must occur after the start date.');
			g_form.setValue('end_date', '');
		}
	}
}

Hi Mike,

I tried your code, now i am not getting that getDateFromFormat error in portal, but i am able to select even the past dates which should not happen.

The requirement i got was:

1) The start date should not be selected as the past date and should only select after 2 business days prior to the current date. Like for example if today is 3/21, user should only be able to start selecting from 3/23.........

2) I need the end date should be after start date.

 I am implementing this in portal. Can you please help me with the code?

Hi Mike

We found your post helpful for date validation.

I would like to know how can we use moment in future and it will be helpful if we get documentation about it.

Thank you.
