Hi, this is really nice stuff!

For a source of inspiration and new ideas, check out the Rx (Reactive framework), using LINQ for async events.

Intro here:
http://themechanicalbride.blogspot.com/2009/07/introducing-rx-linq-to-events.html

Perhaps you can extend your elegant approach to Linq in Javascript to be used for chained event processing (instead of deeply nested callbacks).

With all that Ajax and events driven UI programming in browsers, this may be a very valuable extension.

Haha – Yeah, I didn’t do a good job creating an “online presence” for myself — I’m scattered around the web with several different aliases.

jLinq is still worked on from time to time (mostly screencasts now). I haven’t gotten much feedback on what people would like to see added and I’m not personally getting any new ideas! (I already copied as much as I could from the 101 LINQ Samples page!!)

In any case, I appreciate the compliment! Let me know if you have any ideas to make it better!

Awesome stuff! I have used this on a project and what a time saver. You really have created something great. By the way, I didn’t “link” you to jLing until a moment ago. I was at Hugoware.net, jumped to your article on CodeProject and after a series of hops ended up back here.

Now I really want to know what you think of Silverlight! Don’t give the Javascript stuff dude!

Interesting concept – I think I understand what you’re saying about parent/child navigation.

As for now, you can get partial child navigation by just using the actual name of the object as you saw in the example before.

Parent navigation seems possible, but I’d have to experiment to say for certain.

Thank you for your suggestions!

I’m talking about:
“Performs a recursive search for the given property name, returning an array of all values with such a property name in the current object and any subobjects”-from http://docs.persvr.org/documentation/jsonquery . In essenсe,I’m talking about “true” query language for “select” a’la XQuery/XPath,with “axis” parent/child navigation support for descendants of “from” object.For example:
“a..b[c]“-filter all “b” properties on any level of object graph.Look at JSONPath docs for details.

Thanks.

I’m not sure that I follow you. Could you write a sample query (not like the a.b.c one below) that shows what you are suggesting? I’m very interested to hear your thoughts .
Thank you

Thanks,it’s actually help a little.But I still prefer implicit over explicit property mapping(by convention)-it’s simply more natural IMHO.Accessor methods are unavoidable in legacy JS,but things changes and future versions of JS seems to support implicit property accessors.It seems natural to me to implement them on framework level.
What do you think about http://github.com/jcrosby/jsonquery/tree/master and JSONPath in general?Don’t you think you complicate things slightly- “from(…).select(a).select(b).select(c)”… maybe “from(…).select(“a.b.c”)” a little easier?

Actually, you can — Check out this page in the docs…

http://jlinq.net/docs/?tipsandtricks

Basically, when you access the field itself, methods or array indexes… so for example…

//method names
jLinq.from(data).greater(“totalSum()”, 50)

//array indexes
jLinq.from(data).equals(“permissions[0]“, “read”);

You can actually even take it a step further and access the object that is returned like..

jLinq.from(data).equals(“manager.name.first.charAt(0)”, “s”);
