Hi all,

How to get list of roles belong to the user in drop down in catalog item?

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.

Hi,

I am getting below error, please correct it

Hi @uma 

Did you try to copy the whole function (in Script Include) and Client Script as I have changed the parameter "sysparm_val" and did you also ensure that:

• Script Include is Client Callable
• Client Script is onChange and it is on Field/Variable corresponding to Requested For

Please check these and let me know if this solves your issue.

Hi @uma 

In the response, you are receiving an array of objects so we need to adapt our client script, so please find the updated Client Script:

Client Script:

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

  function onChange(control, oldValue, newValue, isLoading, isTemplate) {
     if (isLoading || newValue === '') {
  	   
  	   //If form is loading or Requester is empty then
  	   //Clear the options
  	   g_form.clearOptions('role');
        return;
     }
     
     //Clear options to rebuild the list on change of Requester
     g_form.clearOptions('role');
     
     //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);
  	if(answer) {
  		for(var i = 0; i < answer.length; i++) {
  			var objList = JSON.parse(answer[i]);
  			g_form.addOption('role', objList.sysID, objList.name);
  			
  			//Select the Last Option
  			if(i == answer.length - 1) {
  				g_form.setValue('role', objList.sys_id, objList.name);
  			}
  		}
  	}
  }

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