I am trying to implement a clickable HTML/CSS/Javascript based layer component on top of an ongoing broadcast, such as a clickable advertisement banner at the top of the broadcast.
But being a novice to the TAL framework, I am currently trying to figure it out on the example project provided by BBC here:
https://github.com/bbc/talexample
Any assistance towards the usage of broadcast object in the TAL framework, or a general advice would be a huge help for me as I am struggling to understand the framework.
TAL's documentation for Broadcast TV Widget can be found here: https://bbc.github.io/tal/other/broadcast.html
My work overall is based on HbbTV's, if it makes any difference.
I'm not very familiar with TAL but the broadcast widget you have linked seems to be used to control de broadcast object (showCurrentChannel(), getCurrentChannelName(), setPosition(top, left, width, height), etc) so, if you only need to build a clickable banner over the broadcast you don't need to deal with the broadcast object.
Starting from the talexample you can:
Adapt the static/style/layouts/720p.css to fill only your desired area off the screen instead the current fullScreen style
Alse you should remove some fullscreen assets like background-image: url(../../img/bbc_background_720.png) from the css
In order to test a minimum set of features, remove some of the sample components and leave just a button or similar to test your modifications.
After that works, you can start to implement the image widget or the widget you want

I know this site was built on react. I want to know more about how to get that background animation and mouse over effect. It's simply awesome to experience. Based on this I will decide to go with React or Angular 2.
If you open your browser's inspection tool (almost always F12) you can see the layout of the webpage. It contains a canvas element with the id "grid". The animation is made using this.
The animation itself looks like a simple node graph, where if you move your cursor the nodes close to the cursor try to stay away from it, thus creating an explosion-like effect.
If your cursor stays fix for 2-3 seconds, the animation starts using a point going randomly across the page instead.
I doubt this animation uses too much of any of the libraries you mentioned in your question, thus deciding which one of these you will be using based on this demo (which let's be honest, max 200 lines of vanilla JavaScript) is like deciding what you eat for breakfast based on the food statistics of Mongolia.
And also, animations like this are what scares off most users. I don't think you can show me any big multimedia or social network site, which has animation close to this.
I'm developing a PhoneGap/Cordova application with AngularJS. Since my target platform is Android I looked into different approaches for activity transitions. In other words; How to animate the transition between form A and form B while providing a native and intuitive user experience.
My application will be implementing the material design guidelines and I stumbled upon a transition animation called "shared element transition" which I think would work perfectly for most of my application flows.
I actually really like this approach and was wondering about how to achieve an implementation based on Angular 1.5 which is as generic and flexible as possible and easy to use across the application.
Since I'm still new to AngularJS, I wanted to check back with the community to find a neat way to implement something along the lines of the shared element transition or maybe get pointed to an already existing implementation.
For those wondering, I'm using Angular 1.5 and MaterializeCSS to empower my app. Thank you very much!
Check this tutorial (ready made component to use as well), it animates hero elements between different views and maintains proper routes.
http://blog.scottlogic.com/2014/12/19/angular-hero-transitions.html
To summarize, the hero element has to exist between the two views being transitioned. When transitioning, the hero element is temporarily hidden in the target view till the position animation ends. If the target view is being loaded directly (refresh, bookmark), no animation takes place and the hero element is there.
I'm currently working to develop a real estate website for a client. The client is stuck with the idea to create something like this :
http://woodfield-sillery.com/plans/
Basically, I'm looking to find a way to recreate the same thing, technically it would require :
Managing image map behaviour (to be able to react to mouseover)
Managing the onclick to open a view of the selected floor
Once selected, a second map would show of the floor, with available condos
Then onclick again, it would show pricing, availability, etc.
I'm having trouble managing the rollover image map through CSS.
Besides that, of course, the client would want to manage all by himself (so he can update the condo statuses), and I was planning to host the website through Wordpress
Questions :
Has anyone worked on a solution like this and would be willing to share experience?
Has anyone come across a Wordpress solution that works this?
Has anyone have a technical solution for this (Javascript, HTML5, CSS combined?)
I'm the author of MapSVG WordPress / jQuery plugin which is able to do what you need: http://mapsvg.com
To get started you would need to create a blank image in any vector editor (InkScape, Adobe Illustator, etc.). Then embed building image (png/jpeg) to the background. Then add shapes on top of the image and give them a transparent color fill (=rgba(0,0,0,0)). Save image as SVG, upload it to MapSVG map builder.
Everything else will be done in MapSVG Builder - colors, tooltips, popovers, links, event handlers, etc. See the demo.
you can use maphilight plugin
or you can use jvector

I am reconstructing a massive collection of medical modules that were created in Flash. All of the modules are being redesigned for cross platform enjoyment (js and HTML5). I have been searching for a library or plugin that will add arrows(with rollover capabilities) and text above an image when the user clicks a button. I have had little luck.
The closest package I have found is Zoomify, but it's still not what I am looking for. They are asking for too much money for maximum development capabilities. I was really hoping to find a JQuery plugin or javascript library that would allow me to fully customize the interface. Here is a screenshot of an OLD FLASH module:
The red arrow corresponds to the link selected on the left. The new design is much more appealing but the underlying idea is the same, click buttons point to the objects.
If there is no such library or plugin should I create a simple javascript image viewer and store overlay coordinates in a database? Or is that overkill? I have hunderds of these things to do... maybe thousands :( Any help/direction would be greatly appreciated.
What you are asking for is provided by CSS, which enables one to place text directly on top of an image or other rendered HTML. The key CSS properties to investigate are:
position set to 'absolute'
values for at least two of top, right, bottom or left
use z-index to specifying layering/order
Lightbox is a good option "Lightbox is a simple, unobtrusive script used to overlay images on top of the current page. It's a snap to setup and works on all modern browsers."
Sencha Touch seems like an amazing way to develop mobile apps. I've seen posts by people incorporating Jquery, D3.
At the same time the posts describing customizing controls seems to be fairly narrow.
Adding the picture of a kitten next to the slider and labeling the slider seems kinda tame compared to what ios can do in terms of custom controls, at least in terms of examples available. Most blog posts imply you can extend the control objects in Sencha or the CSS file.
These posts are not quite what I'm looking for - that's my problem. I can't see any examples of anyone changing default controls in Sencha touch, but they make it sound as if it might be possible to do anything.
This is my question:
Is Sencha Touch able to build an iOS or Android App incorporating any javascript library or HTML5? Are there any limitations here?
To give an example I trying to implement a custom slider, where a touch along a continuous line or a circle like this color selector will enter new values. Further if you incorporate a library like protovis or D3 (or Raphael charts) can Sencha display anything the graph canvas element will otherwise display? Will it take touch input and interact with the graph libraries the way that the HTML5 graph does?
The post you mentioned is not about customizing controls, it's about displaying a list from bound store, instead of of using just Ext.XTemplate (the system with Ext.view.View) to generate HTML, it uses ComponentView to generate Ext.Components instead.
It's hard to tell what you're asking, what in particular are you trying to do?
To address some of the questions you added:
Charts in Sencha are implemented using Raphael, which uses SVG, therefore all the elements in the chart can be interacted with using HTML events.
Everything that Sencha generates is valid HTML, you can listen to HTML events, but components usually abstract the lower level events into something that is easier to consume, (for example a data view abstracts the click so that it passes the record being clicked along with the event).
Therefore, the answer to the question is, YES, Sencha can co-exist with regular HTML. If you want the full benefit of the framework, you should always create an Ext.Component so that your components can be easily used within the framework's layout containers.
It's very easy to misuse Ext when trying to write regular HTML and still place that within the layout rendering pipeline. Ext.Component has a built in way of creating HTML out of templates, see http://docs.sencha.com/touch/2-0/#!/api/Ext.Component-cfg-data and http://docs.sencha.com/touch/2-0/#!/api/Ext.Component-cfg-tpl
