Hi I guess that the problem is in that array in js are not associative arrays even thought its looks like they can do that at first glance
aAssetToggled['LNum0']['T'147'] = "true"; the 'LNum0' and 'T147' are not realy indexes/keys of the array example: var a = new Array(); a['x']=1; // a.length = 0 // check that why you get empty array -->> its realy empty because the x is not an index/key of the array but just another property of the object a. if you want a "keys array" use a hash http://api.prototypejs.org/language/Hash/ its already has a toJSON method. I didnt check the prototype js toJSON but I believe thats your problem regards Yuval On Sat, Nov 27, 2010 at 2:50 AM, theotherdy <damion.yo...@googlemail.com>wrote: > I've been struggling for hours to get an array (aAssetToggled[LNum] > [T]) toJSON so I can save, by Ajax, it to a db in CakePHP - all I get > is '[]' - this is how Chrome shows it to me: > > aAssetToggled: Array[0] > LNum0: Array[0] > T147: "true" > length: 0 > __proto__: Array[0] > LNum1: Array[0] > LNum2: Array[0] > T147: "true" > length: 0 > __proto__: Array[0] > LNum3: Array[0] > length: 0 > __proto__: Array[0] > > I'm sure I must be doing something wrong as all those 0's suggest that > Chrome, and presumably Prototype, think the array itself has no length > and contains zero-legth arrays.
