calling a script include from a client script

[oharel]

Hi all,

A quick one (hopefully 😞

I have a change request form which has a "classification type" field. If the classification type is set to "standard" then a new field appears, in which the user can choose the relevant standard change request. Standard changes are on a different table (u_standard_change_requests).

I would like to make it so that if a standard change is chosen, and a standard change number is inserted in the relevant field, two other fields in the change request form are populated with the information from the standard change. The two fields are short description and description.

I created a script include:

Name: getStandardFields

var getStandardFields = Class.create();
getStandardFields.prototype = {

   getFields : function() {

   var standardFields = new GlideRecord('u_standard_changes');
   standardFields.addQuery('u_number', current.u_standard_change_num);
   standardFields.query();
     },
       type: 'getStandardFields'
};

I created a client script:

On change of the field "Standard Change num":

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


     //Type appropriate comment here, and begin script below
   var classificationType = g_form.getValue('u_change_classification');
     var ga = new GlideAjax('getStandardFields');//this is the script include
   ga.addParam("sysparm_name", "getFields"); //this is the function within the script include
   ga.getXMLWait();
   var findFields = ga.getAnswer();

   if (classificationType == 'Standard') {
   g_form.setValue('short_description', findFields.u_name_of_the_change); //This line is probably incorrect?
   }
 }

u_name_of_the_change is the name of the field in the standard change, that I want to copy to short_description in the current change request form.

So my question is: how do I get to populate the change request "short_description" with values from the standard change?

Thoughts?

Harel,

You just have some syntax errors. Can you paste the screenshot of both client script and script include.? not only the script section, including the name and other attributes of the script.

Also, I just noticed that you have missed a important aspect in your script include and you must extend abstractajaxprocessor

'The sys_script_include code must extend the AbstractAjaxProcessor class and be client-callable.'

Refer:

GlideAjax - ServiceNow Wiki

Example :

var pushRequestedFor12 = Class.create();

pushRequestedFor12.prototype = Object.extendsObject(AbstractAjaxProcessor, {

  test : function()

  {

  return '123';

  },

  type: 'pushRequestedFor12'

});

Hi everyone please find my way of calling the script include from the Client script:

Client Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
	if (isLoading || newValue === '') {
		return;
	}
	
	//Current assignment group
	var assignment_group = newValue;
	
	if(assignment_group){
		var coe = '';
		var ga = new GlideAjax('sn_hr_core.PSPUtils'); //Script include
		ga.addParam('sysparm_name','getCOEbyAssignmentGroup'); //Method/Function
		ga.addParam('assignment_group',assignment_group); //Parameter
		ga.getXMLAnswer(function(response){
			coe = response;
			if(coe){
				g_form.setValue('u_hr_coe', coe);
			}
		});	
	}
}		

This is my script Include:

Code:

var PSPUtils = Class.create();
PSPUtils.prototype = Object.extendsObject(global.AbstractAjaxProcessor, {
	/*
		PSPUtils.prototype = {
		initialize: function() {
		},
	*/
	initialize : function(request, responseXML, gc) {
		global.AbstractAjaxProcessor.prototype.initialize.call(this, request, responseXML, gc);
	},
	/*_________________________________________________________________
		* Description: Get COE by Assignment group
		* Parameters: sys_id
		* Returns: string.
	____________________________*/
	getCOEbyAssignmentGroup: function (assignment_group) {
		var sys_id = this.getParameter('assignment_group') ? this.getParameter('assignment_group') : assignment_group;
		var result = '';
		if(sys_id){
			var grSysChoice = new GlideRecord('sys_choice');
			grSysChoice.addEncodedQuery("element=assignment_group^name=sn_hr_core_case^dependent_value="+sys_id);
			grSysChoice.orderBy('sequence');
			grSysChoice.setLimit(1);
			grSysChoice.query();
			if(grSysChoice.next()) {
				result = grSysChoice.getValue('value');
			}
		}
		return result;
	},
	
	type: 'PSPUtils'
});
