That's pretty much what I did in the end anyway. Didn't have any joy with
flatten()..
----------------------------------------------------------------------------
------------------------
var CradleUtils = {};
/**
* These are REALLY simple serialisation tools meant for simple Hash-like
objects in the for key=val
*/
CradleUtils.deserialize =
function(inStr)
{
return eval('('+inStr+')');
}
CradleUtils.serialize =
function(inObj)
{
var buf = '{';
var cma = '';
for (i in inObj)
{
buf += cma + i + " : "+inObj[i];
cma = ',';
}
buf += '}';
printfire('serialized ['+buf+']');
return buf;
}
----------------------------------------------------------------------------
------------------------
Example Object :
var PANELS = {'a' : true,'b' : false,'c' : true,'d' : true};
----------------------------------------------------------------------------
------------------------
As you say, I am not realy sure of the behaviour for more complex objects. I
used these to set a string value In a cookie to maintain the ui panel
state..

Subject: Re: [Rails-spinoffs] Serialize / deserialize an associative array
As long as the array/object has not been touched by the prototype code (and
thus would add properties to the object), the below should put you on the
right track. I'm assuming you meant associative arrays as in "javascript
treats all objects as associative arrays" and not the Array type object
(which in that case you'd just use a prototype .each() iterator to do
this)...
var obj = {firstKey: firstVal, secondKey: secondVal};
var objStr = '';
for (var p in obj)
{
objStr = objStr + p + ":" + obj[p] + "|";
}
// ...now strip the last "|" symbol and you have your object as a string
delimited by : for name/value pairs and | between the sets of values.
prototype's .flatten() might help also but I haven't used it too much.

Basically just wanna hold some ui state in a cookie.
Did I miss something obvious ?
