Apex Class:
public with sharing class jsonAccount {
public string AccountNameList {get;set;}
public jsonAccount() {
list<Account> accList = [Select Id,Name From Account];
System.debug(JSON.serialize(accList));
AccountNameList = JSON.serialize(accList);
}
list<Account> accList = [Select Id,Name From Account];
System.debug(JSON.serialize(accList));
AccountNameList = JSON.serialize(accList);
}
