JSONCache

This class is adapted from the JSON's PHP class made by Michal Migurski (http://pear.php.net/pepr/pepr-proposal-show.php?id=198) under GPL license.

There is two archives: json.js and JSON.cls

The json.js archive is an adaption from Json class from Mootools for encode a javascript object.

Example of use:

Javascript Code:

var ob={
  tag1:["a","b","c"],
  tag2:{
      a:1,
      b:2,
      c:["c1","c2","c3"]
    },
    tag3:"Hello",
    tag4:12.3
  }     
var str = Json.toString(ob);    
zenPage.MyServerMethod(str);

Server Method :

Method MyServerMethod(str As %String) [ ZenMethod ]
{
    s obj=##class(Utilities.JSON).Decode(str)
    s tag1=ob.GetAt("tag1")
    w tag1.GetAt(2)        // prints "b"
    s tag2=ob.GetAt("tag2")
    s a=tag2.GetAt("a")
    w a        // prints 1                
}

And inverse:

Server Method:

Method AnotherServerMethod() As %String [ ZenMethod ]
{
    s a=##class(aObject).%OpenId("SomeId")
    s ob=##class(%ArrayOfDataTypes).%New()        // this works too with %ListOfDataTypes
    d ob.SetAt(a.%Id(),"id")
    d ob.SetAt(a.Name,"name")
    d ob.SetAt(a.Address,"address")
        
    q ##class(Utilities.JSON).Encode(ob)
}

Javascript Method:

var myObject=zenPage.AnotherServerMethod();
var ob=Json.evaluate(myObject);
alert(ob.id);        // alert the id
