Sharepoint JSOM client object model code to retrieve other list item in Nintex Form

When using the SharePoint JavaScript client object model, your code needs to be broken up into two parts: the first part specifies what you want to get, and involves you loading queries and commands into an SPClientContext object; the second part lets you manipulate the results of the query to SharePoint, and runs as an asynchronous callback of the query execution.

1. Create your context, specify which lists you want to access, etc.
2. Run clientContext.executeQueryAsync() (where clientContext is an SP.ClientContextobject), and pass in delegate functions to run on success or failure
3. In your "onSuccess" delegate function, you can work with the results of the commands you loaded up in step 1

function FormLoading()

{

console.log('Inside Jcode Form Loading Calls');

NWF$("#" + JSLeaveType).change(function()

{

EmpLeaveBalance();

});

}

function  EmployeeLeaveBalance()

try

{

NWF$("#" + JSLeaveBalance).val("");

var clientContext = SP.ClientContext.get_current(); 

var web = clientContext.get_web(); 

var oList = clientContext.get_web().get_lists().getByTitle("LeaveSBalanceS");

var newCRUsername = varCRUsername.replace('downlevelTextBox','upLevelDiv');

var varCRUsernamevalue= NWF$('#' + newCRUsername).find('span.ms-entity-resolved').attr('title');

var lists = new SPAPI_Lists('');

var userprofiles= new SPAPI_UserProfile('');

var currentUserProfile = getUserProfileInfo(userprofiles,varCRUsernamevalue); 

var userFullName = getFullName(currentUserProfile);

//alert('UserFullName  '+userFullName);

//var varCurrentUser = clientContext.get_web().currentUser();

//var accountname = currentUser.get_title();

//console.log("accountname --> " + accountname);

var camlQuery = new SP.CamlQuery();

/* Use a CAML query to filter your results */

camlQuery.set_viewXml( +userFullName+ );

//camlQuery.set_viewXml('' + userFullName + '' + (new Date()).getFullYear() + '');

/* get the list item collection from the list */

        var oListItems = oList.getItems(camlQuery);

var LeaveType=NWF$("#" + JSLeaveType + ' option:selected').text(); //Nintex form control is lookup field then get selected text
