Please rectify the error coming in logs for the date field validation

[rishabh31]

Hello Team,

Can anyone please help me to get this error resolved and make these scripts work?

Requirement- 'Date to Disable' (Date type variable) should not be the Past date, it can be either today's date or any future date.

To achieve this I wrote below the client callable script Include:

validateDatetoDisable.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    nowDateTime: function() {
        var disableDate = this.getParameter('sysparm_disable_dt');
        gs.log('Rishi Disable Dt ' + disableDate);
        var cDate = new GlideDate();
        gs.log('Rishi Current Dt ' + cDate);
        //return gs.dateDiff(gs.nowDateTime(), disableDate, true) / 86400;
        //return gs.dateDiff(cDate, disableDate, true) / 86400;
        return gs.dateDiff(cDate, disableDate, true);
    },
    type: 'validateDatetoDisable'
});​

Then I wrote onChange Client Script on change of Date to Disable and called the above script include as below:

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

    var disDate = new GlideAjax('validateDatetoDisable');
    disDate.addParam('sysparm_name', 'nowDateTime');
    disDate.addParam('sysparm_disable_dt', g_form.getValue('date_to_disable_account'));
    disDate.getXML(compareDisableDate);

    function compareDisableDate(response) {
        var answer = response.responseXML.documentElement.getAttribute("answer");
        //if (answer <= 0) {To neither allow current date nor past date
        if (answer < 0) { //To allow current date but not past date
            g_form.addErrorMessage("Date to Disable should not be the Past Date");
            g_form.clearValue('date_to_disable_account');
        }
    }
}

But I am getting the below error (shown in the screenshot/attached) while checking through the logs,

I know this can be achieved through UI Policy Script, but I want this fulfilled through Client Callable Script Include for learning purposes.

Thank You in advance!

Oh, sorry, I completely missed the error from the log that you posted.

That error indicates something else, maybe a scope identifier will help?

Here's how I would do it, if going for the client-script/script include way.

Script include:

Client script:

Thank You @OlaN Sir it is working great, Well Noted 🙂 I will make a habit to use gs.info() instead gs.log() due to the mentioned reason. Both answers are marked as a solution and helpful.

Just a small add, since provided script include not save due to javascript parse/syntax error, so I just added closing '}' after 'if' at line 10/11 in the provided script include (as shown below)

if (systemDay == compareDay) {
		return 1;
}

Further for future reference, the final scripts for Date Validation (The date should NOT be the past date, only today's date or any future date is acceptable) are:

-Script Include (Client Callable):

var DisdtValidation = Class.create();
DisdtValidation.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    isBeforeToday: function() {
        var compareDate = this.getParameter('sysparm_date_compare');
        if (!compareDate)
            return 0;

        var gdt = new GlideDateTime();
        var compareGDT = new GlideDateTime(compareDate);

        var systemDay = gdt.getDate().toString();
        var compareDay = compareGDT.getDate().toString();

        if (systemDay == compareDay) {
            return 1;
        } else {
            if (compareGDT.before(gdt)) {
                return 0;
            } else {
                return 1;
            }
        }
    },
    type: 'DisdtValidation'
});

-Catalog Client Script:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
    var ga = new GlideAjax('global.DisdtValidation');
    ga.addParam('sysparm_name', 'isBeforeToday');
    ga.addParam('sysparm_date_compare', newValue);
    ga.getXMLAnswer(validateDisDt);

    function validateDisDt(response) {
        if (response == 0 || response == '0') {
            g_form.clearValue('date_to_disable_account');
            g_form.showFieldMsg('date_to_disable_account', 'Invalid Date', 'error');
            //g_form.addInfoMessage('Invalid Date');
        }
        if (response == 1 || response == '1') {
            //g_form.addInfoMessage('Valid Date');
			g_form.showFieldMsg('date_to_disable_account', 'Valid Date', 'info');
        }
    }
}

Thank you Once again!
