Serialize JavaScript object into JSON string

Question

I have this JavaScript prototype   Utils MyClass1   function id  member    this id   id  this member   member      and I create a new object   var myobject   new MyClass1  5678999    text      If I do    console log JSON stringify myobject      the result is     id   5678999    member   text     but I need for the type of the objects to be included in the JSON string  like this    MyClass1      id   5678999    member   text      Is there a fast way to do this using a framework or something  Or do I need to implement a toJson   method in the class and do it manually

I was having some issues using the above solutions with an "associative array" type object. These solutions seem to preserve the values, but they do not preserve the actual names of the objects that those values are associated with, which can cause some issues. So I put together the following functions which I am using instead:

function flattenAssocArr(object) {
  if(typeof object == "object") {
    var keys = [];
    keys[0] = "ASSOCARR";
    keys.push(...Object.keys(object));
    var outArr = [];
    outArr[0] = keys;
    for(var i = 1; i < keys.length; i++) {
        outArr[i] = flattenAssocArr(object[keys[i]])
    }
    return outArr;
  } else {
    return object;
  }
}

function expandAssocArr(object) {
    if(typeof object !== "object")
        return object;
    var keys = object[0];
    var newObj = new Object();
    if(keys[0] === "ASSOCARR") {
        for(var i = 1; i < keys.length; i++) {
            newObj[keys[i]] = expandAssocArr(object[i])
        }
    }
    return newObj;
}

Note that these can't be used with any arbitrary object -- basically it creates a new array, stores the keys as element 0, with the data following it. So if you try to load an array that isn't created with these functions having element 0 as a key list, the results might be...interesting :)

I'm using it like this:

var objAsString = JSON.stringify(flattenAssocArr(globalDataset));
var strAsObject = expandAssocArr(JSON.parse(objAsString));

It s just JSON  You can stringify   JSON   var obj         cons    String   some    somemore         func  function param  param2           param2 some    bla             var text   JSON stringify obj     And parse back to JSON again with parse     var myVar   JSON parse text     If you have functions in the object  use this to serialize    function objToString obj  ndeep      switch typeof obj       case  string   return     obj          case  function   return obj name    obj toString        case  object         var indent   Array ndeep  1  join   t    isArray   Array isArray obj         return        isArray    Object keys obj  map function key              return   n t    indent   isArray     key           objToString obj key    ndeep  1  1               join          n    indent         isArray   replace    s t n                                            g          default  return obj toString            Examples   Serialize   var text   objToString obj     To Serialize Object   Result     cons   String  some   somemore    func function param param2  param2 some  bla        Deserialize   Var myObj   eval     text        To UnSerialize    Result   Object  cons  Array 1   func  function  spoof  function

This might be useful  http   nanodeath github com HydrateJS  https   github com nanodeath HydrateJS  Use hydrate stringify to serialize the object and hydrate parse to deserialize

var myobject   new MyClass1  5678999    text    var dto     MyClass1  myobject    console log JSON stringify dto      EDIT   JSON stringify will stringify all  properties  of your class  If you want to persist only some of them  you can specify them individually like this   var dto     MyClass1        property1  myobject property1      property2  myobject property2

You can use a named function on the constructor    MyClass1   function foo id  member        this id   id      this member   member     var myobject   new MyClass1  5678999    text     console log  myobject constructor       function foo id  member          this id   id        this member   member        You could use a regex to parse out  foo  from myobject constructor and use that to get the name

Well  the type of an element is not standardly serialized  so you should add it manually  For example  var myobject   new MyClass1  5678999    text    var toJSONobject     objectType  myobject constructor  objectProperties  myobject    console log JSON stringify toJSONobject      Good luck   edit  changed typeof to the correct  constructor  See https   developer mozilla org en JavaScript Reference Global Objects Object constructor for more information on the constructor property for Objects

Below is another way by which we can JSON data with JSON stringify   function  var Utils       Utils MyClass1   function  id  member        this id   id      this member   member    var myobject     MyClass1  new Utils MyClass1  5678999    text      alert JSON stringify myobject
