I am trying to offer a playlist of videos and only play a video once its link was clicked. Here's my code:
<!DOCTYPE html>
<html lang="en">
<head>
<title>WW Video Player</title>
<link href="http://vjs.zencdn.net/4.0/video-js.css" rel="stylesheet">
<script src="http://vjs.zencdn.net/4.0/video.js"></script>
</head>
<body>
<video id="video_player" class="video-js vjs-default/skin" width="800" height="600" data-setup='{ "controls": true }'></video>
<script type="text/javascript">
videojs("video_player", {}, function() {});
function SelectVideo(path)
{
var mplayer = videojs("video_player", { "controls": true, "autoplay": false });
mplayer.src({ type:"video/mp4", src: path});
mplayer.play();
mplayer.requestFullScreen();
}
</script>
Play Video
</body>
</html>
In the <video> tag, I have tried adding plain controls and removing data-setup, but I can't get the controls to show up.
Furthermore, mplayer.requestFullScreen(); isn't working, either - here's Firebug's error message:
TypeError: mplayer.requestFullScreen is not a function
I'm running Firefox 22.0 on Windows 7 64bit.
Any ideas? Thanks!
Video.js is good and bad at the same time. I appreciate the work that's gone into it, but I've spent days getting it to work correctly. I wish I'd found your answer earlier, codoplayer looks good.
Videojs goes wrong whenever a javascript error occurs, and subsequently fails to set the correct classes on the control bar etc.
The bad javascript could be in your own code, and there is one in video.js that affects Firefox.
First, make sure your own scripts aren't failing...
The function that must be changed in video.js is: vjs.Player.prototype.techGet()
When an exception occurs, it handles it, then re-throws at the end. Replace the line 'throw e;' with 'return null;'
Why? There are methods within video.js that do not seem to realise that techGet could throw.. here is an example:
vjs.Player.prototype.currentSrc = function(){
return this.techGet('currentSrc') || this.cache_.src || '';
};
It throws an exception on techGet whenever the tech is flash, which is common in Firefox, IE8 etc. It will never reach this.cache_.src || ''. It looks like that wasn't the intention, so it's probably a bug.
If interested in IE8, you will have to do something with all the calls to innerHTML, they may fail and will need replacing with a method that works on the DOM instead.

I am playing with video.js. Here is my code:
<link href="//vjs.zencdn.net/5.4.6/video-js.min.css" rel="stylesheet">
<script src="//vjs.zencdn.net/5.4.6/video.min.js"></script>
<video id="example_video_1" class="video-js vjs-default-skin" style="margin-left:auto;margin-right:auto;"
controls autoplay preload="auto" width="1300" height="800"
data-setup='{}'>
<source src="/test.webm" type="video/webm" />
<p class="vjs-no-js">To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video</p>
</video>
The above code was literally copied from the tool's website (except the video and autoplay):
http://docs.videojs.com/docs/guides/setup.html
My movie is played in both Chrome and Firefox. If I want to see something later in the movie, I am able to drag the dot in the progress bar to the point I want and the movie starts just there. However, when doing so in Chrome I got error:
A network problem caused the media download to fail part-way.
You can do it with javascript
videojs("last", {}, function () {
var myplayer = this;
myplayer.currentTime(s); // s being to time in second you want
}
Remove the data-setup attribute from the html tag and put what you had in second argument.
The first argument is the id of the video(be sure it has never been
initialized)
The second is optional it is what you want to have in data-setup
The third is a function that you want to call when it is
initialized.
Can someone tell me the "best" way to detect Safari and then its version number?
Look, I don't want to do it but I can't find a way to pin down a WORKING version of speechSynthesis on Safari
See below for an example that works on iOS 7.1.2 IF you don't add the onEnd listener. Apart from that everything is peachy.
In my real world full blown example it talks but still won't deliver the at end event.
On iOS 8 there is no issue.
Please offer a best-of-breed agent/version sniffer or a better working-feature-detector.
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function fini()
{
alert("end");
}
function talk()
{
if (!('speechSynthesis' in window)) {
alert("Unsupported browser");
return;
}
alert("Getting ready.");
var utterance = "Hello World";
var chat = new SpeechSynthesisUtterance(utterance);
chat.addEventListener('end', fini, false);
speechSynthesis.speak(chat);
}
</script>
</head>
<body>
<p>On Safari this example won't fire any known events<br />
onend, onerror, even onended: -</p>
<input type="button" value="Talk" onclick="talk()" />
<br /><br />
No probs on Chrome or Opera. Spewin!
</body>
</html>
For the record, the addEventListener was throwing an exception on 7.2.1 that could be trapped to signify unsupported speech synthesis.
Opera mobile has laryngitis
Different problem same topic: -
You (and I) may question the correctness of this behaviour in Opera but it appears to be as simple as there are no known/registered/available voices for Opera Mobile on my Android phone :-(
"Sing for me Christine! Sing my angel, SING!" Sorry couldn't help it.
So are there any files I have to download?
FYI on Safari, apparently, the speechSynthesis.getVoices method is synchronous which makes life easy. Elsewhere it is asynchronous and will return an array of length 0 on first call.
We need to register an event such as: -
speechSynthesis.onvoiceschanged = function() {
voices = window.speechSynthesis.getVoices();
alert("Voices " + voices.length);
if (!done) theWork();
};
This never fires on Opera Mobile. Curious!
Why don't I get a error from the synthesis specification like "language-unavailable" or "voice-unavailable"?
Because I didn't explicitly specify a language and a voice?
And why does Chrome deliver onvoiceschanged 3 times?
I'm trying to load an epub on my page using epub.js library and its not working on IE 11, it works perfrectly on chrome and Firefox though.
I'm not getting a script error, I don't get a message in the console log, fiddler says all scripts (including zip.js and my epub) are downloaded properly.
It just doesn't load, the iframe embedded has a src="" property and an empty html body. as in the following snapshot.
Here is my html page content:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title></title>
<script src="content/epubjs/epub.js"></script>
<script src="content/epubjs/libs/zip.min.js"></script>
</head>
<body>
<span onclick="Book.prevPage();">Prev</span>
<span onclick="Book.nextPage();">Next</span>
<div style="height: 700px; border: 5px solid red" id="area"></div>
<script type="text/javascript">
EPUBJS.filePath = "content/epubjs/libs/";
</script>
<script type="text/javascript">
var Book = ePub("content/aliceDynamic.epub", {
version: 4,
restore: false, // Skips parsing epub contents, loading from localstorage instead
storage: false, // true (auto) or false (none) | override: 'ram', 'websqldatabase', 'indexeddb', 'filesystem'
spreads: false, // Displays two columns
fixedLayout: true, //-- Will turn off pagination
styles: {}, // Styles to be applied to epub
width: false,
height: '700px'
});
Book.renderTo("area");
</script>
</body>
</html>
I tried to play around with the options parameter, set things to false and true here and there but it didn't help.
It looks like it is a problem with the current version of epub.js and internet explorer 11. If you try and load the moby dick page you should see the same problem.
Try setting a break on all exceptions (even handled ones) in the javascript engine of IE, and you will see that the javascript throws an exception saying that "'XPathResult' is undefined".
Common recommendations to correct that seem to be installing the wicked-good-xpath library in order to sidestep ie11 lack of XPath support. Install the library and initialize it before trying to load you epub.
If this doesn't correct your problem, you may have to wait until the issues are solved since you don't seem to be the only person who encounters it.
When clicking the links, I get the popup box as expected however the images won't load, it just spins and spins. all the paths are ok as far as I can see.

Chrome console gives these errors which are general as far as I can see and not related to this (although I know, they need sorting!)

After using various versions of colorbox and jQuery I finally found a set that works well together and solves this issue as it was simply down to the versions of colorbox and jQuery I was using. jQuery 1.6.4 and the current version of colorbox work together perfectly.
I'm trying to add a simple progress bar to my application in rails using jquery-ui. I'm following this example: http://jqueryui.com/progressbar/
I create the div
<div id="progressbar"></div>
and in my JS I have
$(document).ready( function() {
$("#progressbar").progressbar({
value: 37
});
});
But nothing happens to the div in the html - it remains empty and unstyled(ie no additional CSS is applied to it).
I have checked that I have jquery-ui included in my application - in particular, I have made certain the jquery-ui css file is included.
However, I am willing to bet the problem has something to do with jquery-ui not working properly in my app, because I was having another issue with it and the tooltip function, which I asked about over here: positioning jQuery tooltip
This is driving me nuts, does anyone have any ideas?
I had the same problem right now.
It seems like the referenced libaries in the example do not work.
The error i get from the "Firefox - Developer Tools - Browser Console" is:
ReferenceError: $ is not defined
(I tested on Firefox 32.0.3 and IE 11)
If you just copy the example html/jquery source from "http://jqueryui.com/progressbar/" to a local file (lets call it: "testJqueryProgressBar.html") and double click it, you will see no progress bar!
Source of "testJqueryProgressBar.html":
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>jQuery UI Progressbar - Default functionality</title>
<link rel="stylesheet" href="//code.jquery.com/ui/1.11.1/themes/smoothness/jquery-ui.css">
<script src="//code.jquery.com/jquery-1.10.2.js"></script>
<script src="//code.jquery.com/ui/1.11.1/jquery-ui.js"></script>
<link rel="stylesheet" href="//jqueryui.com/resources/demos/style.css">
<script>
$(function()
{
$( "#progressbar" ).progressbar({ value: 37 });
});
</script>
</head>
<body>
<div id="progressbar"></div>
</body>
</html>
Therefore i checked the links in the header of the example and all reference something.
So the links are valid!
I even tried to reference the jquery libs from another provider, f.e. : https://developers.google.com/speed/libraries/devguide?hl=de#jquery-ui.
Same problem!
Then i went to http://jqueryui.com/download/
Selected Version : 1.11.1 (Stable, for jQuery1.6+)
Selected a different UI theme at the bottom
Downloaded the zip and referenced these unziped jquery sources in my local example testJqueryProgressBar.html and it worked.
