Calling Script Include from Catalog client script

[vidhya_mouli]

I am having an issue in calling a script include:

Catalog Client Script:

var TotalSmsGA = new GlideAjax('EmploymentUtils');
TotalSmsGA.addParam('sysparm_name', '_getTotalSMS');
TotalSmsGA.getXML(getSMSLength);

function getSMSLength(response) {
var test = response.responseXML.documentElement.getAttribute("answer");
console.log(test);
}

Script Include:

_getTotalSMS: function() {
return '100';
},

SI is client callable.
I am getting the result as null. Any suggestions for what is wrong here?

Try a function name without the leading _ / special character.  Do you happen to have more than one SI with the same name?  Is the SI in the same application/scope as the Catalog Item / Catalog Client Script? If not, use the scope name in the GA call:

var TotalSmsGA = new GlideAjax('global.EmploymentUtils');

try without "_"  

getTotalSMS

Hi @vidhya_mouli,

Use the following tried and tested on my PDI (leveraging a random onLoad Client Script and Cat Item):

I'm alerting the result of 100 so you can confirm it's working. You'll just need to assign that to whatever variable or use appropriately for your use case.

Client Script:

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


    var TotalSmsGA = new GlideAjax('EmploymentUtils');
    TotalSmsGA.addParam('sysparm_name', 'getTotalSMS');
    TotalSmsGA.getXML(getSMSLength);

    function getSMSLength(response) {
        var test = response.responseXML.documentElement.getAttribute("answer");
        alert(test);
    }

}

Script Include:

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

	
    getTotalSMS: function() {
        return '100';
    },

    type: 'EmploymentUtils'
});
