Semantic zoom in browser HTML5 (NOT win.js) - javascript

I am building a web SPA and I'd love to use semantic zoom. I rather not bother implementing it, so I was wondering if such a library has already been built (SO and googled showed only results concerning Win.Js).

I found the following jQuery plugin library. while it is not in itself a semantic zoom library it can Aid you in creating semantic zoom.

When you zoom on an element it adds the class selectedZoomTarget you could use this in css to show/toggle more data inside your target.
The page doesn't show examples of nested zoom targets but you might be able to do it using jQuery click events.

Image viewer in html5

I have to develop an image viewer application. The designed application should have the following features
Zoom in functionality
Zoom out functionality
Magnifying functionality
Pan functionality
Image overview functionality
I have to develop the application in Asp.net application. I have the following questions
What will be the better method to develop such application , I mean Whether it is implemented using Asp.net controls or standard HTML controls
Have any scope of HTML5 in developing such application?
Can i get any customizable open source project written in javascript or jQuery?
My answers to your questions:
I would use HTML, since you don't need anything from the server.
There is, you can search google for info.
Look at the info below.
I would try the following steps:
Look for examples of the required features.
Strip these examples down and build them up again according to your requirements.
Create a holder for the image. You can load the image from the server with jQuery and AJAX
Implement controls for zooming, panning. Use the implementation you created in step 2
There is alot of information to be found on the internet. Some examples are:
Zooming

Panning

For me,
I would use HTML,
Use HTML5 and CSS3 if you can,
Yes, there are plenty. Just type what you need. It seems what you are building is a image slider/gallery. Plenty of those on the web. Just look for it.
If you have to build it from scratch, what you could do is research, these css properties. scale, zoom, and transitions.
There you go, hope I pointed you in the right direction.

How general is Sencha Touchs javascript?

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

Javascript/CSS Tooltip that you can hover over and click

I'm looking for a javascript/css tooltip that can do the following:
Shows up when you hover over some page element (such as a help icon.)
Repositions itself based on the browser window (for example if it's on the far right of the page, it will show itself to the left of the page element, otherwise it'll show to the right of it. That way it won't go off of the page.)
You can hover over the tooltip and it won't disappear. This way you can select text or click on a hyperlink within the tooltip.
I'm using dojo but their dijit tooltip seems to be very inflexible, as it can only spawn off of another dijit element, most commonly a dijit button. I'd rather not having to reference a whole other javascript framework like jquery or prototype so hopefully someone has a way to do this using just one basic script.
Unfortunately for you, the tooltip style plugins available for Dojo are nowhere near the other frameworks (namely: jQuery). Because of this, you have three options:
Reinvent the wheel. Take what you learned from other tooltip scripts and build your own from scratch. This option takes the longest development time (and in the inevitable maintenance of cross-browser bugs).
Extend an existing plugin. You can take a current tooltip plugin for dojo (or perhaps a library agnostic plugin) and extend its functionality by adding your own scripts to it.
Use jQuery. This has already been said twice by others, but let me say it again. jQuery has a thriving plugin ecosystem, and if development/maintenance times are truly important to you, then jQuery should definitely be considered.
Again, assuming that you don't mind using jQuery (it's awesome!!) I played around with a few tooltips and found this one the best: http://flowplayer.org/tools/tooltip/index.html
Extensible with good documentation. Check out the 'position' config option and see if that does what you need.
Good luck!
If you do decide to use jQuery, qTip is a nice jQuery plugin that is very configurable and will probably meet your needs. http://craigsworks.com/projects/qtip/
I have been using several jQuery plugins, including jQuery TOOLS, Beauty Tips and Cluetip. I think all three meet your requirements.
If instead of a black box you want to know what's going on, I recommend this tutorial:
http://www.sohtanaka.com/web-design/simple-tooltip-w-jquery-css/
(and take a look at the comments section)
The dijit.Tooltip documentation gives two simple examples, the first attaching a tooltip to simple DOM nodes seems to meet your needs. The second happens to wire up the tooltip to another dijit-based widget (a button). Note that the property connectId takes a dom node reference or string id. Note that dijit may be used either programmatically or using a markup-based declaration.
Different tooltip implementations may have different functionality. Among other things, dijit.Tooltip provides ARIA accessibility for screen readers, keyboard access, bidi enablement, and automatic positioning around a node but within the boundaries of the screen.

Javascript tabs widget with drag and drop reordering

Do you know of a tab widget that has built-in drag+drop reordering? I'm building an editor-like interface and want to allow the user to reorder their tabs.
So far I've been using ExtJS with a community plugin, but it's buggy and usually needs updating with every new ExtJS release.
Is something like this what you're looking for?
I'd definitely use jQuery and jQuery UI as a base if I was trying to do what you are. The solid support structure and wealth of tutorials around jQuery is unbeatable!
Of course this is if you don't mind the weight of another javascript framework or having to recode some of your interface.
On a slight tangent, if you want your interface to remember a user's preferences you'll need a server-side language. Alternatively, use the jQuery cookie plugin to store preferences between page loads.
There's a draggable tab widget based on YUI lib just for that.
If you're not concerned about adding another javascript lib to your application, I think it's an interesting alternative. You can even drag and drop tabs from other containers (I didn't see this feature on your ExtJS plugin by the way).
There are attempts to make jquery tabs drag and drop able. While it is not drag and dropable out of the box you could make them yourself in jquery-ui.
Here are some resources that tried it:

Dynamic Floating window by javascript

I want to build a dynamic floating window with close button at corner. Is it possible, and also i want to add some content dynamically into that window.
Please help me.. It should be in javascript.. Better without AJAX..
Thanks in Advance
jQuery UI has an awesome floating window. What's cool about the jQuery UI version is that you can also package it with the UI theme manager, which means less time styling.
Check it out here : jQuery UI Dialog examples
All it takes is creating a container (probably a div), and one line of code. Something like this:
<div id="example">I'm in a dialog!</div>
$("#example").dialog();
Here's the documentation: jQuery UI Dialog documentation
What you are looking for is called a "lightbox" technique.
Here is a comparison of many lightbox techniques.
Many exist out there on the web, here are some for jquery and prototype libs:
Jquery: Thickbox, Lightbox
Plugin
Prototype: Lightbox 2,
Leightbox
Also, check out the
wikipedia article on lightbox.
My favourite has always been Scriptaculous, which lets you do all sorts of interesting visual things. The new kids on the block use jquery. One of these two should do the trick for you.
There are lots of samples on both sites that do what you want.
Well at the most basic just create a div and inject content by setting innerHTML to an HTML string. Positioning it can be tricky since you have to worry about scrolling and different browsers have different means of controlling this. You may also want to position relative to some originating element in the page which you can do by digging the element and it's position out of the event object your javascript function receives when the originating element is clicked.
Google hover popup - first link is http://www.calcaria.net/javascript/2006/09/javascript-hover-over-html-popup.html
There are lots of different libraries out there for making windows. I have found that Livepipes has a very well rounded and customizable javascript library that includes a window control along with a variety of others. http://livepipe.net/control
One that I haven't used but looks promising, is prototypeui. It is based on the prototype and scriptaculous javascript libraries. jqModal is another I have used that is based on JQuery.
take look at fancybox http://fancybox.net/
