I've been playing with HTML5 location lookups recently and its relatively straightforward to pull someones location from a device like an iPhone. I want to write an app that uses location data, but its important that the location be factual. In other words I need to prevent people from authoring a fake post to the backing website / web...
I've got a web page for the iPhone that uses the HTML5 video tags. On the iPhone, such embedded videos are played in the native player. I wanted to notice when the video had ended and when the user had dismissed the video with the "Done" button. Initially, I tried this: var video = $("#someVideo").get(0); vi...
Right, so this is strange. This code works as expected: HTML: <section> Section #1 </section> <section> Section #2 </section> <section> Section #3 </section> CSS: section{ margin-right: 30px; } section:last-child{ margin-right: 0; } The first two sections get a right margin of 30px, while the third section doesn...

Hi, I'm creating an SVG rectangle using the Raphael JavaScript library, and assigning it a fill using the following line of code: this.myBox.attr({fill: 'white'}); This works fine. However, now I want to tie this to a linear gradient. I have borrowed some gradient code to test it out, using the code below: <defs> <linearGradient id=...
What audio formats can be played using the html5 'audio' tag in the android browser? Does anyone know where to find official specs on what the android browser supports and not? For the record, the android media formats page does not seem to cover this - I have soundfiles (3gp) playing fine in a native app, but they won't play in my weba...

I am looking for a way to let the user expose some local data to an webapp. The idea is to have a webapplication that goes somethings (e.g. plots a chart, edits photos, etc...) using information directly from the desktop instead of requiring the user to upload the data. While some of it might be possible with some technologies like Flas...
I am trying to live stream my desktop over http to one or more users. The immediate goal is just to share the desktop in real time in read only mode for several users. In future we might allow the users to control the desktop as well by mouse or keyboard. I have these queries in this context- Is HTML5 + H.264 right for this or do I ne...
I've been considering converting my current HTML5 documents to polyglot HTML5 ones. I figure that even if they only ever get served as text/html, the extra checks of writing it XML would help to keep my coding habits tidy and valid. Is there anything particularly thrilling in the HTML5-only space that would make this an unwise choice? ...
I found web-socket-js for running WebSocket in Flash. If I run WebSocket under Flash, can all browsers with Flash player installed support this? ...
Hi. I'm using the HTML5 JW Player. It sizes the HTML5 video correctly, but shrinks the Flash fallback player; here's an example page: Test Page If you view that page in IE, you'll notice that on panel 5, the video is smaller than the space it's supposed to occupy. On Firefox, it works fine because it's using the OGG video in its HTML5 v...
I want to have a web page coded with HTML5, and I want to be able to put a pdf file onto this page so you can view it without having to click on any links to download it separately. Anyone know how to do this? I want it to keep the text, images, and layout of the pdf file also. If that weren't the case I would just use an image. Thanks! ...
Is there any way that a webpage can make a request for the users location from the android / iphone device ? Since all I need is the users location, I am trying to figure out if there is anyway I can bypass developing a native app and use some nifty html5 call to just get the users location so all a user would need to do is visit my web...
I'm learning about Html5. <html> <body> <canvas id="canvas1" width="300" height="200"></canvas> <script> var canvas = document.getElementById("canvas1"); var cxt = canvas.getContext("2d"); context.fillRect(0, 0, 150, 100); </script> </body> </html> How to set color for this Rectangle? ...
Despite all the hype, in reality the HTML5 video tag has a bit of a problem. In order to use it and for it to be cross browser compatible, you have to include more than one format of the video. To target all supported browsers these formats are mp4 and ogg. I was searching around for optimum settings for each format but unfortunately I...
I was playing around trying to create a small safari extension, most for the fun of it and to see what you could do etc. Anyways I was thinking about storing some data for my extension in a local database, so I always would have it where I needed it, across page loads. I searched a bit on google and found this snippet from the Safari R...
I have a webapp that I'm building, and have just started with SQLite. I have been able to create my form, open the database I created, create the table, and fields i need, and enter data into the fields. Now I'm trying to read the data back out with a SELECT statement, to show it on screen and as a list of the columns. I just don't ...
I'm trying to create a simple WebSocket example using the HTML5/JS API. Based on what I trace out on the server, it seems like the socket is connecting, but none of the events fire (onopen, onmessage, onclose, etc). I'm a Flash developer so I'm not very good at debugging the JavaScript and I'm hoping someone can help me out. Here's the c...
