Preamble: I'm Italian, sorry for my bad English.

I need to retrieve the name of the property from a json object using javascript/jquery.

for example, starting from this object:

{

      Table: {

          Name: Chris,

          Surname: McDonald

       }

}

is there a way to get the strings Name and Surname?

something like:

//not working code, just for example

var jsonobj = eval('(' + previouscode + ')');

var prop = jsonobj.Table[0].getPropertyName();

var prop2 = jsonobj.Table[1].getPropertyName();

return prop + '-' + prop2; // this will return 'Name-Surname'

var names = [];

for ( var o in jsonobj.Table ) {

  names.push( o ); // the property name

}

In modern browsers:

var names = Object.keys( jsonobj.Table );
