I'm trying to use the event system for TVML and am running into issues/lack of documentation. The TVML JS Kit documentation hints at there being a ElementListenerObject but I'm having trouble setting it up. Has anyone seen any further documentation or examples of how this works?
Specifically I'm trying to solve a problem where I calling into JavaScript code after a long running Swift method and need to let certain objects know of the results
One of the options is to use deferred execution from Swift code. You will have to create global function in js and then tell your Swift code its name. When Swift code will be ready to populate result you just need to execute that global function. This technic is similar to JSONP.
Here is how it could be implemented in swift
And how to use it in js

I'm trying to set up a basic component that is rendered on the server and the client. The component is populated with data from a JSON API. I've got this working on the client-side by loading my data in componentDidMount and calling this.setState when it has loaded.
The problem I have is that the data isn't loaded on the server. How do I get the initial data into the server-rendered version of my component?
https://github.com/rackt/react-router/blob/latest/docs/guides/advanced/ServerRendering.md is very vague about this:
For data loading, you can use the renderProps argument to build
whatever convention you want--like adding static load methods to your
route components, or putting data loading functions on the
routes--it's up to you.
Do you have an example anywhere of how to do this? It seems like a very basic thing for a universal application to want to do!
Yup - we have https://github.com/rackt/async-props that provides a library for dealing with async data between server and client, and provides an example for doing so. If you're using a Flux framework, you'll want to make appropriate adjustments, but the basic approach will be quite similar.
I am trying to achieve something like which is mentioned in this link
but i don't know whereto write the parsing code. I tried to write it in new method and added the method in "my adapter.xml" but nothing happens. I even don't know how to log in IBM WorkLight. I used WL.logger(some) but its throwing error that "Logger can not be called on an object".
Any help would be appreciated. Thanks in advance.!
In most cases you don't need to manually parse responses because WL adapter framework will do this for you. Anything you retrieve via WL.Server.invokeHttp API will be parsed to JSON automatically unless you specify returnedContentType:"plain". In case you DO need to manually parse JSON you can use JSON.parse() and JSON.stringify() APIs.
Server side logging is achieved via WL.Logger.debug/error/info etc. You can get more info about it here
You don't have to parse JSON data, there are libraries in Javascript to do that. Try JSON.parse(). You should learning how to write adapters and invoking them from clients. The Getting Started modules are a good place to start, specifically Module 4 in your case.
I am developing my first HTML 5 application which has to read data from a web service.
Can anybody tell me how I can call a web method from HTML 5 using JavaScript ?
In this question you have an answer what should you put in order to call a web method in HTML.
How can I call this HelloWorld web method with plain JavaScript/Ajax, without using JSON or anything?
It is using ajax, but it should give you an example. Also take a look at the answer
I need to know how to implement the external paging and sorting method of displaytag in struts2.
In the reference documentation, there is only jsp page information.
Further they provide that a class should implements the PaginatedList Interface for making the external paging and sorting.
Using the object of the PaginatedList implemented class, we can do the external Paging.
I tried the method that has been used in the following link Answer provided in the DispalyTag Pagination Problem
But the problem I am facing now is, after implementing the abstract methods of the PaginatedList ,
How to use the object of the class to perform the external paging function?
How to set the values for the methods?
And how to retrieve the index and page numbers in action class?
The object is not retrieved in the jsp page.showing error like size attribute is not defined.
I searched the internet, but I could not find any clear resources or examples.

I would like to ask if someone know how to grab a facebook event json message. It doesnt matter if it has to happen programatically. I just want to be able to read the message one way or another.
thanks in advance.
P.s. Maybe an awful question but here you go !!!
I once had to code a small chunk of code to parse a json-encapsulated message. However recently I found out there's a handy solution for it if you use Java
Resty is a small, convenient library
to talk to RESTful services from Java.
It’s surprisingly complex to do the
simplest HTTP calls with the standard
Java library. Resty hopes to change
that.
http://beders.github.com/Resty/Resty/Overview.html
Resty r = new Resty();
Object name = r.json("http://ws.geonames.org
/postalCodeLookupJSON?postalcode=66780&country=DE")
.get("postalcodes[0].placeName");
Just import a small jar lib and you'll be surprised. I currently use this class for getting info from url API.
