You can download it from http://yepnopejs.com/.

As for why the data is not key/value pairs, that’s because the method is returning a representation of a DataTable’s rows, not a Dictionary of column names and values. You would need to use a different data access approach to change that. Something that pulls the data out into a Dictionary, or similar. Rob Conery’s Massive is an example of that approach (not sure if it works with MySQL though).

If you absolutely must have access to a WebControl during the AJAX request, you’ll need to use something like an UpdatePanel instead. Just keep in mind that you’ll be trading away significant performance for that convenience. If at all possible, figure out a way to work around that need by passing the dropdown’s client-side value as a parameter to the page method and/or setting the dropdown’s selected value on the client-side based on the result of the page method.

For that matter, even Crockford’s json2.js uses eval() in its implementation of JSON.parse (after a bit of input sanitizing). There were parse-only implementations floating around, but it turned out to be prohibitively slow in the older JavaScript engines that need JSON.parse polyfilled.

I suppose what I’m saying is that you have to be careful about making blanket statements about eval(); especially in historical context. “Eval is evil” comes from Crockford, but his own acceptance of eval() for JSON evaluation played a critical role in JSON being a viable format in the first place.

I just prefer having it on my side, compressed, gzipped, and merged with other files.

Of course, some users will benefit from CDNs, but many users will feel the opposite effect.

So many great posts – i think i’ve read all blogpost about .net/jquery/json.

I’m a noob developer, and pretty confused, think i’ve used about 4-5 hours trying googling and reading, but i didn’t found a solution.

My issue:
I’ve some data in a mySql db, and i want to provide this data to a phonegap, so i need to use JS in some way, and jquery doing a great job!
But the guide i’ve used( http://williamsportwebdeveloper.com/cgi/wp/?p=494 ) using JavaScriptSerializer and it shoudn’t, cause as you write the response is:
{“d”:”[[\”Tobias Mobil\”,\”152\”,\”Skid skud \”
and not
{“d”:”[[“restaurant_name”:”Tobias Mobil”,”dish_id”:”152,”dish_name”:”Skid skud”
as it should…
My webservice: http://dagensret.com/GetDishes.asmx/GetDishesByDates

So please help me :)

I need an example using data from a mySql database.

Thx in advance

Thanks for your reply!

I have just quickly tried that out. One other question, how can I reference a control on the page. For example, a drop down list as it come up with an error as it’s a static method?

Thanks
