Change Client Script calling a Script Include

[Dead Blade]

Hello Developers,

I am trying to call a script include from an onchange client script and populate a u_Field. The script include returns a group.  The client script needs to supply the cmdb_ci and the group type.

I've been attempting to use something similar to: https://community.servicenow.com/community?id=community_question&sys_id=a77707a1dbc023c09d612926ca961925&view_source=searchResult

with little luck. 

Here is the script include:

var Group_and_CI = Class.create();
Group_and_CI.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    
    getallValues : function() {
        var output;
        var grp = this.getParameter("sysparm_grp");
        var cmdb = this.getParameter("sysparm_ci");
        var gr = new GlideRecord('u_m2m_groups_configuratio');
        gr.addQuery('u_group', grp);
        gr.addQuery('u_configuration_item', cmdb);
        gr.query();
        if(gr.next()) {
            output += gr.sys_id+"\n";    
        }
        return output ;
    },
    
    type: 'Group_and_CI'
});

Can someone help me with the Change client script?

can you paste your updated script include and client script here

Also update your callback function since you are returning a single value (sys_id) in this case.

 function callback(response) {

    var result = response.responseXML.getElementsByTagName('result');

    g_form.setValue('u_glide_list_areas_impacted', result);

    
}

So your client script should be:

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


    var ga = new GlideAjax('Group_and_CI');
    ga.addParam('sysparm_name', 'getallValues');    
    ga.addParam('sysparm_ci', g_form.getValue('cmdb_ci'));
    ga.addParam('sysparm_grp', '75da0d45dbcc7380b825abc5ca96196e');  // Release Coordinator  '75da0d45dbcc7380b825abc5ca96196e' sys_id
    ga.getXML(callback);

    function callback(response) {

    var result = response.responseXML.getElementsByTagName('result');


    g_form.setValue('u_glide_list_areas_impacted', result);

    
}

}

Close David.  Your client script is close, but it is inserting "[object HTMLCollection]" into the List type field, it should be a group name.  This is the closest I have gotten to populate the u_field.

Try this for your Script Include:

var Group_and_CI = Class.create();
Group_and_CI.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    
    getallValues : function() {
        var output = '';
        var grp = this.getParameter("sysparm_grp");
        var cmdb = this.getParameter("sysparm_ci");

        var gr = new GlideRecord('u_m2m_groups_configuratio');
        gr.addQuery('u_group', grp);
        gr.addQuery('u_configuration_item', cmdb);
        gr.query();
        if(gr.next()) {
            output = gr.getUniqueValue();    
        }

        return output;
    },
    
    type: 'Group_and_CI'
});

Also I see one more issue with the client script. Try the following:

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


    var ga = new GlideAjax('Group_and_CI');
    ga.addParam('sysparm_name', 'getallValues');    
    ga.addParam('sysparm_ci', g_form.getValue('cmdb_ci'));
    ga.addParam('sysparm_grp', '75da0d45dbcc7380b825abc5ca96196e');  // Release Coordinator  '75da0d45dbcc7380b825abc5ca96196e' sys_id
    ga.getXML(callback);

    function callback(response) {

    var answer = response.responseXML.documentElement.getAttribute("answer");


    g_form.setValue('u_glide_list_areas_impacted', answer);

    
}

}

This is the following line that was changed:

var answer = response.responseXML.documentElement.getAttribute("answer");
