check the string length

[Fabrizio Joaqui]

hi, i have a problem, i have this function in the client script and in the second if

i want that if the condition is true I call the getReport () function which as input must have its own sys_id,
otherwise I print a paragraph on the screen that says "select a field" how do I do?

below the client and the script server

//Client

function init(){
		if(!!c.data.report && c.data.report.length){
			
			getReport(c.data.report);
		}
		else{
			var objToSend = {
				action: c.data.EVENTS.getUserPreferences,
				report_sys_id: c.data.report
			};
			c.server.get(objToSend).then(function(response){
				if(response.data.prefReport.length){
					getReport();
				}else{
					//create div that say 'select a value'
				}
				
			});
		}
	}

//Server script

function getReport(input){
		try{
			var reportGR = new GlideRecordSecure('sys_report');
			reportGR.addQuery('sys_id', data.report);

			reportGR.query();

			if(reportGR.hasNext()){
				$sp.log('reportGR: ' + reportGR.title);
			}


			var request = new sn_ws.RESTMessageV2();
			request.setEndpoint('/api/now/table/sys_report?sysparm_query=sys_id%3D' + input.report_sys_id);
			request.setHttpMethod('GET');
			
			request.setRequestHeader('Accept','application/json');
			request.setRequestHeader('Content-Type','application/json');

			request.setRequestHeader('X-UserToken', input.g_ck);
			//request.setRequestHeader('X-UserToken', token);

			var response = request.execute();
			$sp.log('report: ' + response.getBody());
			data.reportResponse = response;

		}
		catch(e){
			$sp.log("error in getReport: " + e);
		}
	}

Pls try following.

response.data.prefReport.toString().length

Thanks

[Fabrizio Joaqui]

is already a string

[Harshad Wagh]

i guess if statement is expecting some true value.

if(response.data.prefReport.length>1) or something? Can you add some evaluation there?

Thanks

yes, the data.prefReport variable is initialized as an empty string.
data.prefReport = ''; 
and I'm checking if the string is not empty you call me the getReport () function which as a parameter must take the sys_id, 
otherwise you write me a paragraph or a div in the page that tells me 'select a field'
