Hi all,

Please suggest me the script include and catalog client script to achieve this requirement.

Thanks

Hi @uma

Please update your scripts as provided below:

Script Include: Just to remind

Client Callable: true

Script:

var yourScriptIncludeName = Class.create();
yourScriptIncludeName.prototype = Object.extendsObject(AbstractAjaxProcessor, {
			getStates: function() {
				var list = [];
				var userValue = this.getParameter('sysparm_val');
				//Issue1: Table name was not in quotes
				var map = new GlideRecord('sys_user_has_role');
				map.addQuery('user.sys_id', userValue);
				map.query();
				while (map.next()) {
					var eObj = {};
					eObj.name = map.role.name + '';
					eObj.sys_id = map.getValue('role');
				list.push(eObj);
			}
		}
		return JSON.stringify(list);
	},
	type: 'yourScriptIncludeName'
});

Client Script:

Type: On Change
Field/Variable: Field corresponding to req

Script:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
   if (isLoading || newValue === '') {
      return;
   }
   
   //GlideAjax Call to fetch Roles for Requestor
   var ga = new GlideAjax('yourScriptIncludeName');
   ga.addParam('sysparm_name', 'getStates');
   ga.addParam('sysparm_val', newValue);
   ga.getXMLAnswer(stateCallback);
}

function stateCallback(answer) {
	alert('answer=' + answer);
	var i = 1;
	var objList = JSON.parse(answer);
	g_form.clearOptions('role');
	for (var keys in objList) {
		g_form.addOption('role', objList.sys_id, objList.name);
		i++;
	}
	
	//Select the Last Option
	g_form.setValue('role', objList[i].sys_id, objList[i].name);
}

Remark: Ensure the variable/field is of Type Choice.

Please mark my answer as correct if this solves your issues!

If it helped you in any way then please mark helpful!

Thanks and regards,

Kartik

Can you explain more please with screenshots..your question is not clear

Kindly share what you have started with & tried & where you are stuck.

The logic of Script include is what is to be followed but you can also try below.

1. Drop down (Lookup selectbox) field of catalog items to reference User Role table

2. You can pass qualifier as

javascript: 'user='+current.variables.variable_name;

//replace variable_name with user variable from Catalog item

This is okay but we have to achieve via script include and client script because we have to achieve some more customizations.

Hi jaspal,

I have tried below script include and client script but it is not working, Please correct it as per my requirement.

script include:

getStates : function() {

var list = [];

var userValue = this.getParameter('sysparm_Val');

var map = new GlideRecord(sys_user_has_role);

map.addQuery('role', userValue);

map.query();

if (map.next()) {

var eObj={};

eObj= map.getValue('role');

list.push(eObj);

}

return JSON.stringify(list);

},

client script :

var userVal = g_form.getValue('req');

var ga = new GlideAjax('useRrole');

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

ga.addParam('sysparm_Val', userVal);

ga.getXMLAnswer(stateCallback);

function stateCallback(answer) {

alert('answer=' + answer);

var objList = JSON.parse(answer);

var selected = 0;

g_form.clearOptions('role');

for (var i = 0; i < objList.length; i++) {

var obj = objList[i];

g_form.addOption('role', obj.value, obj.label);

if (obj.selected) {

selected = i;

}

g_form.setValue('role', objList[selected].value, objList[selected].label);

}
