GlideAjax returning null from Script Include

[NishmithaS]

I'm trying to convert List Collector sys_ids to user names using GlideAjax. The List Collector returns comma-separated sys_ids, which I pass to a client-callable Script Include. However, the GlideAjax response is always null.

Script include 

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

getName: function() {
var ids = this.getParameter('sysparm_ids');
var names = [];

var gr = new GlideRecord('sys_user');
gr.addQuery('sys_id', 'IN', ids);
gr.query();

while (gr.next()) {
names.push(gr.getValue('name'));
}

return names.join(',');
},

type: 'getwatchlistusernames'
});

Catalog Client script 

var ga = new GlideAjax('getwatchlistusernames');

ga.addParam('sysparm_name', 'getName');

ga.addParam('sysparm_ids', g_form.getValue('user'));

ga.getXMLAnswer(callback);

function callback(response) {

    alert(response);

    // g_form.setValue('short_description', response);

}

Hi @NishmithaS 

Try this:

1. Script include

var getwatchlistusernames = Class.create();
getwatchlistusernames.prototype = Object.extendsObject(AbstractAjaxProcessor, {
getName: function() {
var ids = this.getParameter('sysparm_ids');
if (!ids) {
return '';
}

var names = [];
var sysIdArray = ids.split(',');
var gr = new GlideRecord('sys_user');
gr.addQuery('sys_id', 'IN', sysIdArray); //corrected here
gr.query();
while (gr.next())
{
names.push(gr.getValue('username')); //corrected here
}
return names.join(',');
},
type: 'getwatchlistusernames'
});

2. Catalog Client script

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

var ga = new GlideAjax('getwatchlistusernames');
ga.addParam('sysparm_name', 'getName');
ga.addParam('sysparm_ids', g_form.getValue('user'));
ga.getXMLAnswer(callback);
}
function callback(response) {
alert(response);
if (response) {
// g_form.setValue('short_description', response);
}
}

@NishmithaS Try Below Scripts

Script include:

var GetWatchlistUsernames = Class.create();

GetWatchlistUsernames.prototype = Object.extendsObject(AbstractAjaxProcessor, {

    getName: function() {

        var ids = this.getParameter('sysparm_ids');

        var names = [];

        var gr = new GlideRecord('sys_user');

        gr.addQuery('sys_id', 'IN', ids);

        gr.query();

        while (gr.next()) {

            names.push(gr.getDisplayValue('name'));

        }

        return names.join(',');

    },

    type: 'GetWatchlistUsernames'

});

Client Script

var ga = new GlideAjax('GetWatchlistUsernames');

ga.addParam('sysparm_name', 'getName');

ga.addParam('sysparm_ids', g_form.getValue('user'));

ga.getXMLAnswer(function(answer) {

    alert(answer);

});

Hi @NishmithaS 

1. Please ensure the client callable is checked.

2. ​If your Client Script is running in a scoped application (or Global) and the Script Include is in a different scope. ServiceNow will block the call unless:

​The Script Include's Accessible from field is set to All application scopes.

​You can add the name to your GlideAjax call (e.g., new GlideAjax('x_abc_scope.getwatchlistusernames')).

If my response helped mark as helpful and accept the solution.
