I've serialized an object using Newtonsoft's JSON serializer, and the DateTime has come through as: /Date(1237588418563+0000)/ When I $.evalJSON() on that, it is an object but I can't find any normal Date methods like toUTCString on it. Any ideas what I can do with this? ...
Hi there, two functions need to be executed in Javascript, the second one only after the first has finished. The first populates an array with getJSON, and the second will then manipulate it. However, getJSON is asynchronous, thus it will not pause the order of execution to make the program work properly so that the array finishes load...

I reflected this on the client side with data: "{paramname:'" + paramval+ "'}", I now get the following error when the webmethod returns. This happens regardles...
I'm writing a JSON service in C# (.ashx file). On a successful request to the service I return some JSON data. If the request files, either because an exception was thrown (e.g. database timeout) or because the request was wrong in some way (e.g. an ID that doesn't exist in the database was given as an argument) how should the service re...

I am looking for a simple Json (de)serializer for Java that might work with GWT. I have googled a bit and found some solutions that either require annotate every member or define useless interfaces. Quite a boring. Why don't we have something really simple like class MyBean { ... } new GoodSerializer().makeString(new MyBean()); new...
I have my json serialization working fine render :json => "#{current_object.serialize(:json, :attributes => [:id, :name])} But I also want to add further data to the json before it gets set back to the client. Mainly the auth_token. Googled around like crazy but I can not find what option serialize will take to allow me to append/me...
I have a user control, on load of which I have some data from the database. A user can manipulate the data in different ways (CRUD). The process of manipulating data can cause server side events or at the client side. Then there is a save button on the page that eventually processes the temporary data and writes it to the database. I am...
I am stumped with this problem. ActiveSupport::JSON defines to_json on various core objects and so does the JSON gem. However, the implementation is not the same -- the ActiveSupport version takes arguments and the JSON gem version doesn't. I installed a gem that required the JSON gem and my app broke. The issue is that I'm using to_js...
I am trying to json_encode an array, which is what returns from a Zend_DB query. var_dump gives: (Manually adding 0 member does not change the picture). array(3) { [1]=> array(3) { ["comment_id"]=> string(1) "1" ["erasable"]=> string(1) "1" ["comment"]=> string(6) "test 1" } [2]=> array(3) { ["comme...

But when I do echo "{'result':'hhh'}"; It isn't The only difference I find between the two requests is that the first one has: Content-Length: 9 header and the second o...
When I first saw XML, I thought it was basically a representation of trees. Then I thought: the important thing isn't that it's a particularly good representation of trees, but that it is one that everyone agrees on. Just like ASCII. And once established, it's hard to displace due to network effects. The new alternative would have to...
With a Javascript Array, I can reset it to an empty state with a single assignment: array.length = 0; This makes the Array "appear" empty and ready to reuse, and as far as I understand is a single "operation" - that is, constant time. Is there a similar way to clear a JS Object? I know I can iterate its fields deleting them: for (pr...
