I would like to handle the youtube errors in the JWPlayer, so in case the video doesn't exists or is not available for the country show a message on the player, or with javascript, i am doing something like this...
var options = {
height: 330,
},
flashplayer: '/player.swf',
width: 560,
events:{
onError:function(obj){
alert('ERROR'+obj);
}
} ,
debug: 'console'
};
jwplayer("player").setup(options);
jwplayer("player").play();
but its not getting inside from the onError event, even though the video doesnt even exist... and i can see in the console.. LOG (Error loading preview image: Error #2036)
In the case of youtubes restriction country i cannot even see that in the console.
In any case the video just show the loading animation, which it makes belieave the user that it can be load in any time, which its not true.

loadPlayer to try with jwplayer.js and the createPlayer directly from SWFObject... that video exist just that it shouldnt be shown in germany, still its trying to load it.
and if i set any other unexisting URL let say "http://www.youtube.com/watch?v=ABC" still keeps trying to load the unexisting video.
It looks like JW5 doesn't support catching YouTube errors. However, the following setup with JW6 works:
<!DOCTYPE html>
<html>
<head>
<title>YouTube Test Page</title>
<script type="text/javascript" src="http://www.longtailvideo.com/jwplayer/jwplayer.js"></script>
</head>
<body>
<div id="player"></div>
<script type="text/javascript">
jwplayer("player").setup({
file: "https://www.youtube.com/watch?v=ABCD",
events:{
onError: function() {
jwplayer().load({file: "http://content.longtailvideo.com/videos/flvplayer.flv",duration: "27"});jwplayer().play()
}
}
});
</script>
</body>

I want one or more videos to play/pause depending on whether or not they're in the viewport.
I understand this can be achieved with jQuery (and plugins), so I've tried using the isInViewport plugin along with the following code, but I receive the error shown below.
HTML
<script src="scripts/jquery.js"></script>
<script src="scripts/isInViewport.js"></script>
[...]
<video id="video1" src="file.mp4" width="50%"></video>
[...]
<script src="scripts/script.js"></script>
JS
var $video = document.getElementsByTagName("video1");
if ($video.is(":in-viewport")) {
$video.play();
} else {
$video.pause();
};
Console
TypeError: $video.is is not a function
try
$('video').each(function() {
if ($(this).is(":in-viewport")) {
$(this)[0].play();
} else {
$(this)[0].pause();
}
}
);
I wanted paperjs to load after a button is pressed to turn on animations but it seems the paperscript doesn't work if paper is loaded after page load.
If you comment out the setTimeout and uncomment the direct $.getScript - paperjs will fire the alert('hi'). I don't get it.
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function () {
var paperUrl = 'http://cdnjs.cloudflare.com/ajax/libs/paper.js/0.22/paper.js';
$("#jq").text("jQuery is now loaded.")
var lateLoad = function() {
$.getScript(paperUrl, function() {
$("#pp").text("Paperjs is now loaded.");
});
};
//setTimeout(lateLoad, 100);
$.getScript(paperUrl, function() {
$("#pp").text("Paperjs is now loaded.");
});
});
</script>
</head>
<body>
<script type="text/paperscript" canvas="myCanvas">
$('body').css({"background-color": "#999"});
alert('hi!');
</script>
<p id="jq">jQuery NOT loaded yet.</p>
<p id="pp">Paperjs NOT loaded yet.</p>
</body>
</html>
I'm using Chrome 23.0.1271.97 m on Windows 7 x64. Anybody have an idea what's going on here?
I think I figured out a workaround as well - paper.PaperScript.load() or to elaborate:
<html>
<head>
<script src="http://code.jquery.com/jquery-latest.js"></script>
<script>
$(document).ready(function () {
$("#jq").text("jQuery is now loaded.")
var paperUrl = 'http://cdnjs.cloudflare.com/ajax/libs/paper.js/0.22/paper.js';
var lateLoad = function() {
$.getScript(paper_url, function() {
$("#pp").text("Paperjs is now loaded.");
paper.PaperScript.load(); // <-- The fix!
});
};
setTimeout(lateLoad, 1000);
//$.getScript(paperUrl, function() {
// $("#pp").text("Paperjs is now loaded.");
//});
});
</script>
</head>
<body>
<script type="text/paperscript" canvas="myCanvas">
$('body').css({"background-color": "#999"});
alert('hi!');
</script>
<p id="jq">jQuery NOT loaded yet.</p>
<p id="pp">Paperjs NOT loaded yet.</p>
</body>
</html>
That causes paperscript to scan for all the paperscripts. I found it at https://github.com/paperjs/paper.js/blob/master/src/core/PaperScript.js#L270 while googling for "paperscript" in the github repo. Though it still doesn't explain why paper doesn't do the load() on its own when dynamically loaded.
EDIT - I understand what went wrong. It's related to https://github.com/jquery/jquery/blob/master/src/core.js#L768 because paperjs doesn't check if the window loaded event had already fired i.e document.readyState === "complete". I submitted a pull request to paperjs https://github.com/paperjs/paper.js/pull/156
I think it is easier to load it via require.js. All you need is a require.config object, defined in e.g. main.js:
requirejs.config({
paths : {
'jquery' : "path/to/jquery"
'paper' : "path/to/paper"
},
shim: {
'jquery' : {
exports: 'jQuery'
},
'paper' : {
exports: 'paper'
}
}
});
You will need to load require.js with the above config via the data-main attribute:
<script data-main="scripts/main.js" src="scripts/require.js"></script>
Then you define a module (e.g. 'paperStuff') where your paper logic will be:
define(['jquery', 'paper'], function($, paper) {
// do some cool stuff
});
When you want to load your paperStuff, you just do
var paperStuff = require('paperStuff');
...
Move your paperscript code into an external file (i.e. pstest.js) and modify your lateLoad to:
var lateLoad = function() {
$.getScript('http://cdnjs.cloudflare.com/ajax/libs/paper.js/0.22/paper.js',
function() {
$("#pp").text("Paperjs is now loaded.");
$.getScript("pstest.js");
} )
}
Trying to set up a basic backbone.js example - can't get events to fire. What am I missing?
HTML
<html lang="en">
<head>
<script type="text/javascript" src="js/libs/jquery/jquery-1.6.4.min.js"></script>
<script type="text/javascript" src="js/libs/underscore/underscore-min.js"></script>
<script type="text/javascript" src="js/libs/backbone/backbone.js"></script>
<script type="text/javascript" src="js/test.js"></script>
<title></title>
</head>
<body>
<div id="helloworld">
<button id="sayhello">
Say Hello
</button>
</div>
</body>
And here is JS
(function($) {
HelloWorldView = Backbone.View.extend({
el : '#helloworld',
events: {'click #sayhello': 'onButtonClicked'},
onButtonClicked: function()
{
console.log("buttonclicked");
},
render : function() {
console.log("rendering");
$(this.el).html("Hello world");
}
});
var helloView = new HelloWorldView().render();})(jQuery);
Any idea why I can't get the events to fire?
Your render method kills #sayhello:
render : function() {
console.log("rendering");
$(this.el).html("Hello world"); // #sayhello is now gone
}
So there is no #sayhello to click on and your event handler never gets called.
Perhaps your render is supposed to look more like this:
render: function() {
console.log("rendering");
$(this.el).find('button').html("Hello world");
}
Demo: http://jsfiddle.net/ambiguous/4empG/
actually you replace whole html with "Hello World"
$(this.el).html("Hello World");
it's better, you just find the button and change html.
this.$('#sayhello').html('Hello World');
I've been looking for something that will authorize a textbox when user types something and I found this ideal plugin:
http://james.padolsey.com/javascript/jquery-plugin-autoresize/
It seems prety straight forward, but for some reason I can't implement it on my website >.< do you guys have any ideas on how to do it? (read the post)
Thank You )))
Here is what I tried, but it doesn't work
HTML
<head>
<script type="text/javascript" src="js/jquery-1.6.js"></script>
<script type="text/javascript" src="js/autoresize.jquery.js"></script>
<script type="text/javascript">
$('textarea.mainStatusTxt').autoResize({
// On resize:
onResize : function() {
$(this).css({opacity:0.8});
},
// After resize:
animateCallback : function() {
$(this).css({opacity:1});
},
// Quite slow animation:
animateDuration : 300,
// More extra space:
extraSpace : 40
});
</script>
</head>
<body>
<textarea class="mainStatusTxt" placeholder="Comment" style="display:block;"></textarea>
</body>
Either wrap your script with:
$(document).ready(function() {
//YOUR CODE
});
or move the entire <script> tag to the end of the document (or at least, after the <textarea>).
From what I've read, this is how I should setup the YouTube API:
<!DOCTYPE html>
<html lang="en">
<head>
<meta content='text/html;charset=UTF-8' http-equiv='content-type' />
<title>Youtube Player</title>
<script src="jquery.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js" type="text/javascript"></script>
<script type="text/javascript" charset="utf-8">
function onYouTubePlayerReady(id) {
console.log("onYouTubePlayerReady() Fired!");
var player = $("#youtube_player").get(0);
}
var params = { allowScriptAccess: "always" };
var atts = { id: "youtube_player" };
swfobject.embedSWF("http://www.youtube.com/apiplayer?enablejsapi=1",
"youtube", "425", "356", "8", null, null, params, atts);
</script>
</head>
<body>
<div id="youtube"></div>
</body>
</html>
However, 'onYouTubePlayerReady()' doesn't fire at all, and if I manually get a reference to the player, a lot of methods are undefined; for example, cueVideoById() works, but playVideo() doesn't.
How can I fix this problem?
You need to be on a web server with your test script, as stated in the documentation:
Note: To test any of these calls, you must have your file running on a webserver, as the Flash player restricts calls between local files and the internet.
this function:
function onYouTubePlayerReady(playerid) {
console.log('readyIn');
};
don't have to be directly in head in separate script tag.
Only rule you have to keep is: don't put this function inside domready event - it has to be defined sooner.
For example in mootools I use it like this:
function onYouTubePlayerReady(playerid) {
echo('readyIn');
};
document.addEvent('domready', function() {
...
});
I have the answer, separate out this portion of the script and put it in the head in its own script tag. OMG, finally
<script type="text/javascript" language="javascript">
function onYouTubePlayerReady(playerid) {
ytp = document.getElementById('ytplayer');
ytp.mute();
};
</script>
I consider this the best way of adding a youtube video to your website with javascript. It gives you a very clear way of dealing with events. It works on a local machine, and as far as I know it works on apple devices. You can use all the events and function described in the javascript documentation for the youtube api.
<div id="player"></div>
<script>
//Load player api asynchronously.
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var done = false;
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'JW5meKfy3fY',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(evt) {
evt.target.playVideo();
}
function onPlayerStateChange(evt) {
if (evt.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>

If you're embedding youtube videos like so:
<iframe src="http://www.youtube.com/embed/VIDEO_ID?jsapi=1" width="1280" height="720" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe>
then you should place
<script src="http://www.youtube.com/player_api"></script>
after the </iframe>. At least that's how I got it to work.
Additionally, if you're dynamically changing the [src] attribute of the iframe via jQuery or whatever to load a new video then you need to call onYouTubePlayerAPIReady() after it has loaded.
I prefer to change the [src] attribute and then:
setTimeout(onYouTubePlayerAPIReady, 500);
Just had the same issue, but for another reason. It worked in Chrome but not Firefox, and the reason was that I had a http header "Content-type: text/xml" instead of "Content-type: text/html". Serving as HTML now fires the onYouTubePlayerReady event in Firefox, too.
Just posting this in case someone stumbles on this answer from Google (like I just did when trying to find a solution).
