Script include returning NULL to Client script

[Omkar Jori]

Hello,

I have created a script include to check if the date entered is in scheule or not, but the script include is returning value as Null.

Please check the below script

Script include:

var execution_date_check = Class.create();
execution_date_check.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    isPublic: function() {
        return true;
    },
    scheduleCheck: function() {
		
        var execution_date = this.getParameter('execution_date');
        execution_date = new GlideDateTime(this.execution_date.getDisplayValue());

		var flag;

        var scheduleID_holidays = new GlideSchedule("755bc0091ba908107a44fd14cc4bcb0d");
		if(scheduleID_holidays.isInSchedule(execution_date)) {
			flag = true;
		}
		else {
			flag = false;
		}
        
        return flag;

    },
    type: 'execution_date_check'
});

Client Script:

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

    var execution_date = g_form.getValue("u_execution_date_and_time");
    var dateTime = execution_date.split(' ');
    var date = dateTime[0];

	var answer = "";

    var ga = new GlideAjax('sn_customerservice.execution_date_check'); //Scriptinclude
    ga.addParam('sysparm_name', 'scheduleCheck'); //Method
    ga.addParam('execution_date', date); //Parameters
    ga.getXML(HelloWorld);

    function HelloWorld(response) {
        answer = response.responseXML.documentElement.getAttribute('answer');
	alert(" answer : " + answer);
    }
}

Both the client script and script include are in Customer service scope and Client callable is enabled in Script include.

Have you checked your system logs for any errors within your client script, for example, you're using this.execution_date which isn't a property of your script include and may be causing your script to fail:

execution_date = new GlideDateTime(execution_date.getDisplayValue()); // removed: `this.`

Hi @Nick Parsons ,
Thank you for your reply.
I tried removing this but getting the same Null in the alert.
Nothing is generating in system logs.

@Omkar Jori Could you please update your client script and script include as follows and see if it works.

var execution_date_check = Class.create();
execution_date_check.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
    isPublic: function() {
        return true;
    },
    scheduleCheck: function() {
		
        var execution_date = this.getParameter('sysparm_execution_date');
        execution_date = new GlideDateTime(this.execution_date.getDisplayValue());

		var flag;

        var scheduleID_holidays = new GlideSchedule("755bc0091ba908107a44fd14cc4bcb0d");
		if(scheduleID_holidays.isInSchedule(execution_date)) {
			flag = true;
		}
		else {
			flag = false;
		}
        
        return flag;

    },
    type: 'execution_date_check'
});

Client script:

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

    var execution_date = g_form.getValue("u_execution_date_and_time");
    var dateTime = execution_date.split(' ');
    var date = dateTime[0];

	var answer = "";

    var ga = new GlideAjax('sn_customerservice.execution_date_check'); //Scriptinclude
    ga.addParam('sysparm_name', 'scheduleCheck'); //Method
    ga.addParam('sysparm_execution_date', date); //Parameters
    ga.getXML(HelloWorld);

    function HelloWorld(response) {
        answer = response.responseXML.documentElement.getAttribute('answer');
	alert(" answer : " + answer);
    }
}

Root cause: You forgot to add sysparm_ suffix before execution_date parameter in client script and script include.

Hi @Sandeep Rajput ,
I did tried adding the sysparm, but no luck.
I understood that there is issue with the date format which I am passing and checking in the script include.
Please help if you notice anything
