by

With this code, you can return multiple values in JavaScript:

  1. Function: 
    function newCodes(){
    var dCodes = fg.codecsCodes.rs; // Linked ICDs  
    var dCodes2 = fg.codecsCodes2.rs; //Linked CPTs       
    return {
        dCodes: dCodes, 
        dCodes2: dCodes2
    };  
}

var result = newCodes();
alert(result.dCodes);
alert(result.dCodes2);

by

With this code, you can call a ready function from outside it:

  1. Define the function on the window object to make it global from within another function scope:

  window.lol = function(){  
    alert('lol');  
  }  
});

ENCODE AND DECODE JSON TEXT FROM JAVA TO JAVASCRIPT – USING MAP

by

JSON.simple is a simple Java toolkit for JSON. You can use JSON.simple to encode or decode JSON text.

  1. Mapping between JSON and JAVA entities:
    JSON Java
    object java.util.Map
  2. Example:
    //import org.json.simple.JSONValue;
    Encode a java.util.List in Java
    Java:

      Map<String, String> obj = new LinkedHashMap()<String, String>;
  obj.put("name","foo");
  obj.put("num",new Integer(100));
  obj.put("balance",new Double(1000.21));
  obj.put("is_vip",new Boolean(true));
  obj.put("nickname",null);

  String jsonText = JSONValue.toJSONString(obj);

    Decode it in JavaScript using LinkedHashMap

    JavaScript:

      var js_obj = JQuery.parseJSON(jsonText);
  // or var js_obj = JSON.parse(jsonText);
  var name = js_obj[name];
  var num = js_obj[num];

  // to see if key exists
  var key = "name";
  if( key in js_obj )
