Question

I have a problem with return a value from an object.
my object looks like this.

   function XYZ(date, startT)
     {
     var _date=date;
     var _startT=startT;
     this.get_date = function() {
       return _date;
       };
      this.set_date = function(value) {
        _date=value;
      };
       this.get_startT = function() {
       return _startT;
       };
       this.set_startT = function(value) {
       _startT=value;
      };
      this.toString()
      return (_date + " " _startT);
      }

then i create an Array like this

   jsData[0] =new XYZ("2012-11-11","8:00");
   jsData[1] = new XYZ("2012-03-03","8:00");

when i want to use get_date method it didn’t return me the value but the get_startT method works fine.
When i show object with .toString method it also show me full object

Please help.

It works if you fix all the syntax errors:

function XYZ(date, startT) {
  var _date=date;
  var _startT=startT;
  this.get_date = function() {
    return _date;
  };
  this.set_date = function(value) {
    _date=value;
  };
  this.get_startT = function() {
    return _startT;
  };
  this.set_startT = function(value) {
    _startT=value;
  };
}

var jsData = [];
jsData[0] = new XYZ("2012-11-11","8:00");
jsData[1] = new XYZ("2012-03-03","8:00");

display("jsData[0].get_date() = " + jsData[0].get_date());

Output:

jsData[0].get_date() = 2012-11-11

Other than obvious typos, here’s what I did:

• Put { and } around the function body.

• Removed the this.toString() which was non-functional (a no-op, as you didn’t store the result anywhere).

• Removed the return at the end, because returning a string primitive out of a constructor function is another no-op.

• Declared jsData.

• Initialized jsData.
