I also recommend using json2.js for anything more then just a basic key-value json string.
I ran into troubles with the standard jQuery json approach, when implementing a complex system that transfers a lot of json to and from the server. And as Michael Geary mentions: "If you want to *generate* JSON in your JavaScript code (e.g. if your server > expects you to send it JSON data in a POST), JSON.stringify() from json2.js > is the way to do it." > Cam On Tue, Aug 11, 2009 at 3:13 PM, MorningZ <[email protected]> wrote: > > "Speaking of: i recommend AGAINST using getJSON()" > > I'd also recommend against use of $.getJSON for a totally different > reason: > > There is no option to "catch" errors..... > > getJSON: function(url, data, callback) { > return jQuery.get(url, data, callback, "json"); > }, > > so if something happens server side or there is a glitch in the Matrix > that we call the internet, your code would just dead stop, and your > user would be sitting there waiting and waiting and waiting > > > > On Aug 10, 9:54 pm, Miket3 <[email protected]> wrote: > > I'll just add my 2 cents from novice to novice. > > 1.
