[SalesForce] How To Convert result into Date in Javascript

public class MyCustomController1
 {

public class studObjectwrap
     {public String D_ob{get;set;}}

@RemoteAction 
public static String createRecord(String jsonObjResult){  
//Some Code od Json Deserialization
Student__c st=new Student__c();
//Converting Date Into Salesforce Date Format i.e MM/DD/YYYY
          String strTest = sc.D_ob;
          String[] arrTest = strTest.split('-');
          String datetosend=arrTest[1]+'/'+arrTest[2]+'/'+arrTest[0];
          sc.D_ob=datetosend;
         //Parsed into Date
          st.DOB__c= date.parse(sc.D_ob);
}

@RemoteAction    
    public static Student__c fetchRecord()
    {
        Student__c student=[
                            SELECT DOB__c
                            FROM Student__c 
                            order by CreatedDate desc limit 1
                           ];
        System.debug(student);
        return student;
    }

//VisualForce Page

function fetchRecord() {     
         MyCustomController1.fetchRecord(handlefetchStudent); 
       }

function handlefetchStudent(result,event){
         if(event.type == 'exception') {
              alert(event.message);
          } else {
         console.log(result.DOB__c.toString());
          }

//but date stored as 1/1/2017 in salesforce org i want same date how to do it?

//Output on console=1483228800000

Best Answer

The field is being written out in epoch time (the number of millseconds since January 1st, 1970). To get it back to a normal date, use the Date constructor:

console.log(new Date(result.DOB__c));

You could have also avoided this issue by serializing the result into JSON before returning, and deserializing afterwards:

@RemoteAction public static String fetchRecord() {
    // ...
    return JSON.serialize(student);
}

// ... In JS
console.log(JSON.parse(result));

[SalesForce] Send chatter files with REST

If I look at your error message:

You have uncommitted work pending. Please commit or rollback before calling out

this means that you make a (rest) webservice call, after you started a database transaction, either you do your webservice call before doing DML statements, or you do your webservice call in an @future method.

[SalesForce] Javascript Remoting (Return cached result without re-query)

There are a couple of things.

In Apex, init() methods are not called by default. Any code you want to run during the instantiation of an Object must go in the constructor, see Using Constructors. Since JavaScript Remoting requires your methods to be Static, setting Instance Variables will not do you any good.
Your static method, "findAccounts" is trying to reference an instance variable, "accounts". I got a compile error when initially trying to save your class. If you want to reference the "accounts" variable from within another static method, make sure to define this as a static list.
Since init() is never getting called, the list of accounts will be null. If you call this init() method within the findAccounts method, then the data will be populated. Note, that you must change init() to be a static method then, as well. As referenced above, it's generally not a best practice to query all objects into memory, as you will soon hit governor limits for the total number of records retrieved by SOQL queries of 50k query rows.

If you put all that together, this should get you at least a working example.

global class MyClass
{
    public static List <Account> accounts = new List <Account>();

    public static void init()
    {
        accounts = [SELECT Id, Name FROM Account]; 
    }

    @RemoteAction
    global static Account findAccount(String accountName)
    {
        init();
        for(Account acc : accounts)
        {
             if(acc.Name == accountName)
                 return acc;
        }

        return new Account();
    }
}

Note, that this will infact requery the database everytime findAccounts is called. A design pattern I like to use, and have seen a lot looks something like the following:

public static List <Account> accounts;
public static void setAccounts()
{
    if (accounts == null){
        accounts = new List<Account>();
        accounts = [SELECT Id, Name FROM Account]; 
    }
}

This will ensure that the query is only run once within the lifespan of the request.

You also may want to utilize a Map<String, Account> accountNameToAccountMap see Apex Maps, so that you can avoid iterating through the list every single time. But, I'll leave that as an exercise.
