I need to create a slide show of some images that can go full screen so it can be displayed via S-Video out.
The software is delivered via the web so a web-based option is needed.
The list of images is dynamic, and I would like to show them in order. The list of photos can change while the slideshow is running, and I would like to add the new photos to the slideshow.
I see two options:
Build it using JavaScript and then use a browser plugin to go full screen. I have a prototype of this, however it displays photos in random order.
Build it using Flash. I know nothing about Flash so I am looking for slideshows that can go full screen.
What would be best? Are there any good, customizable Flash slideshows?
For those interested, I ended up making an Adobe AIR application using HTML and JavaScript. Adobe AIR can go full screen and I was able to leverage the knowledge of HTML and JavaScript I already have. It has worked out pretty well, though there was a rather steep learning curve for the native AIR classes and how to use them.
If you're using Flash, SlideShowPro is a good option that you may recognize from sites like ESPN.
when you say "fullscreen", do you mean taking up ENTIRE screen? if so, javascript is not a tool to use, it must live inside the browser, so you will always have some chrome visible from the browser.
flash can do full screen, on the other hand.
Most browsers allow you to go full screen (even hiding the chrome) with the F11 key (requires user input). Then it's just a matter of scaling the image in javascript to the size of the viewport. If it doesn't exists, it could be written easily enough probably from a preexisting gallery script.
Also, this answer may be helpful
Hope that helps.

I've been tasked with creating a website (using mainly javascript & JQuery) that reads in a certain element from a website - e.g. the navigation bar - and test it to see how it react at different screen sizes.
My question is that is this a good approach? To test elements one at a time instead of just testing the responsiveness of the whole page? Wouldn't an element react differently to media query changes with other elements around it, rather than the element by itself?
My vote will be to firefox default responsive tester. Use Ctrl+Shift+M to make the firefox screen responsive.
If you want to see the dimensions with name, go with google chrome, right-click, inspect element. There you will see a mobile icon. Click that.This will give you a dropdown of variety of devices.
Usually the good approach is to test the whole page. But clearly there are cases when element testing is necessary, even disabling certain ones and check the rest together. So the tool you're about to create actually makes sense; not good enough, tho. But maybe you're better off with a Google Chrome element inspector and some "display:none"-s.
(Side note: this is my own responsivity tester and I never needed much more than this. It aims for the typical bootstrap breakpoints; it has maybe twelve lines of code, it's just as complex as a screwdriver.)
If you want to try it on native devices you should check out www.browserstack.com
There is an extensions for your browser so that you can run local sites (localhost), on the emulated device.
30 min trial is free which is usually enough for a few tests.
I have a table set up on a website I use it to display 9 images with descriptions. I want to be able to click on an image and have it be displayed larger like in a gallery but i would like to not have it change the layout of the page.
I am just starting to work on this web page so almost any way to do this will be helpful.
Lightbox is a pretty commonly used one, but I'd suggest you try and build your own. It's not a terribly difficult thing to program and it will help you grow as a programmer.
We have website that was developed for desktops and now I've been blessed with a task of creating mobile version of it. The mobile design might be quite different from desktop version and the website is build on Wordpress. Now I'm not sure what would be best approach:
shall I stick to CSS changes only (as much as possible) and use media queries to target smaller screens? I'm worried about large images still being downloaded even if these are display:none. There is also quite a bit of JS happening on every page and this JS will not be used in mobile version of the site so I would have to build in additional checks possibly etc. Any other possbile problems with this approach?
server side code should detect if its mobile browser and should return custom html? Any other possbile problems with this approach?
mixture of two above?
any other options?
If anyone has experience with similar project and could point me to what proffered solution would be that would be great.
Use media queries as much as possible for layout changes.
For you JS, create yourself a small breakpoint handler that will trigger the js to run or stop.
I think a lot of people don't realize that a 2x image compressed is smaller than a 1x image compressed. So, if you use compression for you images, you will actually get a better network performance using just large images. How much of that image gets displayed is a potential issue that can cause negative performance, but I imagine that it's insignificant.
Are you using completely different UI for mobile than for desktop or is is just a different positioning of elements? If you have to support two templates then you will want o think about Adaptive(responsive from the server), where the server will determine based on the UserAgent which template to send to the client. UserAgent wont really get you much except for the type of Browser the client has. To figure out the dimensions of the device's screen you will need to know the dimensions or use a service like WURFL.
If you can do all of your UI change in one template using media queries then it might be best to start working on this from a Mobile First approach and basically start from scratch on your mobile look of the site and then figure out how you can re-position the elements on the page to match as close as possible to the current desktop look. Using the Responsive vs Adaptive approach will eliminate the need for UserAgent detection and you will only work with the width of the device.
Thinking of Responsive in "Mobile" vs "Desktop" is really limiting and causes a bit of confusion. Mobile should refer to devices that change location. Try using names like small, medium, and large to describe the layouts(breakpoints) for your Responsive Page.
Finally, there is not preferred way of doing "Responsive." Each site will have it's own requirements that need to be met. It is up to you to learn as much as possible and create the preferred way for your needs.
I am a big fan of the Responsive Theme Wordpress has. It is very customizable, and will allow you to use one site for both Mobile and Desktop.
https://wordpress.org/themes/responsive
You could always use:
<meta name = "viewport" content = "width = device-width">
in your header. Then the whole site will resize to fit the mobile device.
All your js should still work on mobile devices. It would just be 'flash' that wouldn't.
The site isn't "responsive" with this but, depending on the site and how much interaction etc the visitor needs, sometimes this is adequate and simple?
This is my first time asking questions here and I have just started learning jQuery mobile so if it is not quite relevant or if it is just really obvious I apologize in advance.
What I am trying to do is build a mobile site for an online catalog for lots of books.
The original website has a very sophisticated way of filtering and sorting the search results based on the user's input and preference so unless it's absolutely necessary, I would really like to keep the original functionality of the website.
I was thinking maybe I can create a "mask" that looks like a mobile site to cover the real content; and whatever the user requests, I will go "underneath" the mask, do the search and when the data is loaded in the original website, I will then present them in a more mobile-friendly way.
So here is my question:
Is it possible to somehow include/embed a mobile site in the original html?
If so, could you please give me a few hints (books, articles, tutorials, anything) as to how I can approach this?
If not, could you please tell me how I should make the mobile site without having to re-create all the nice functionality that original website already has?
Thank you so much! :)
You could do this but you shouldn't. Mobile websites are optimized for mobile users. Not only as layout but also in loading weight. The direction you are heading you end up with a regular side (probably big in load) and add an overlay (extra load) to rebuild the layout (CPU heavy). So it's not the right way. A better solution is to create a optimized layout for mobile users only.
What is the best cross-browser way to get a flat mouse coordinate input data and simple callback for mouse events for my rectangular game area on my web page, even when it has loads of larger and smaller images and text string overlaid haphazard onto it?
And what is the best way to insert or remove a text string or semi-transparent image overlay at an arbitrary location (and Z order, specified relative to existing objects) in a board game rectangle with cross-browser DHTML?
And how can I stop the user selecting part or all of my montage of images (I just want them to interact with it as if it was Flash), and can I stop the right click menus coming up in IE, FF etc?
I want to do this without Flash because I want something that will work both on desktops and on iPhone and potentially other mobile platforms too.
I appreciate there are serious limitations (eg less image scaling capabilities, not vector, no rotation capability) to what I can do if I'm not using Flash but I'm very interested to know what capabilities are available.
Are there perhaps any frameworks available to make it easier than coding from scratch?
Would J/Query be a good match for some of the requirements? What else do I need?
I would recommend Google Web Toolkit. It lets you program in Java, which gives you all the type-safety and nice IDE functionality that Java entails, but compiles to Javascript so that you can just run it in a browser. It also does a ton of optimization and supports tons of features.
jQuery is excellent at doing this. I used jQuery's UI and Ajax functionality to implement the frontend for a game of chess.
I made it a little easier by creating an 8-by-8 table with unique div names for each tile, so Javascript can access them by getting the elements by id. If you can't create something like that, you do have the option of placing elements anywhere on the page (either absolute or relative to a given element). You can also easily change the z-index, including when the use is dragging a piece or when they have dropped it.
As far as disable right click and item selection goes, that's something that I didn't figure out how to do. You might want to take a look at some other Ajax games like Grand Strategy, which are much more polished than my experiment and may have figured out how to do this.
There are two main APIs for working with arbitrary drawing and positioning on the web, Canvas and SVG.
Take a look at Chrome Canvas Experiments and the Raphael Javascript toolkit to see some examples and Javascript abstractions.
The key is element.style.position = 'absolute'. To illustrate just what's possible here's how far I've managed to push javascript (and from scratch at that!):
