An Iframe Inside Iframe. Can this be done? - javascript

We have a video (vimeo) link we would like our users to watch.
Each video is followed by a short questionnaire.
Our intent is to not make the questionnaire visible to the user until the user had clicked open the video for viewing.
I can only think of embedding the code below inside another iframe just to hide the link.
Is this possible?
Is there an alternative approach to this?

});
// Call the API when a button is pressed

function onPause(id) {

}
function onFinish(id) {

function onPlayProgress(data, id) {

I would use the JS API for video and use the event callbacks built into the player to make the questionnaire visible.
==UPDATE==
Ok - so that link is a step by step example of how to incorporate the JS controls and callbacks for the player. But... here we go..
step 1 is to add the "?api=1" after your initial embed code.
step 2 is to load their Froogaloop library so you can listen for events...
step 3 would be to set up a callback to handle whatever event you want to listen to... The example right from this page is fantastic:
var iframe = $('#player1')[0],
player = $f(iframe),
status = $('.status');
// When the player is ready, add listeners for pause, finish, and playProgress
player.addEvent('ready', function() {
status.text('ready');
player.addEvent('pause', onPause);
player.addEvent('finish', onFinish);
player.addEvent('playProgress', onPlayProgress);
});
// Call the API when a button is pressed
$('button').bind('click', function() {
player.api($(this).text().toLowerCase());
});
function onPause(id) {
status.text('paused');
}
function onFinish(id) {
status.text('finished');
}
function onPlayProgress(data, id) {
status.text(data.seconds + 's played');
}
So, depending on when you want your survey to show, you can just tap into one of those...
player.addEvent('ready', function() {
status.text('ready');
$("#survey_button").show(); // <-- or whatever
});
make sense?
============= ANOTHER UPDATE ================
here's a working fiddle: http://jsfiddle.net/QkGRd/10/. You may want to read a bit about embedding resources and how the jsfiddle works as well.

TL;DR Answer
Yes you can have an iframe inside an iframe. Though it's generally not a good idea in terms of performance.

Using Vimeo API and customize?

I'm using Vimeo's API mostly because I want to play the video through my own button.
The only problem I came across is that when I'm trying to change the buttons content like <button>Play</button> to <button>Play me</button> the video won't play. Why is that?
Fiddle here to see what I mean.
The JS from Vimeo's API.
$(function() {
var iframe = $('#player1')[0];
var player = $f(iframe);
var status = $('.status');
// When the player is ready, add listeners for pause, finish, and playProgress
player.addEvent('ready', function() {
status.text('ready');
player.addEvent('pause', onPause);
player.addEvent('finish', onFinish);
player.addEvent('playProgress', onPlayProgress);
});
// Call the API when a button is pressed
$('button').bind('click', function() {
player.api($(this).text().toLowerCase());
});
function onPause(id) {
status.text('paused');
}
function onFinish(id) {
status.text('finished');
}
function onPlayProgress(data, id) {
status.text(data.seconds + 's played');
}
});
I solved my own question...
What I figured out was that the API is looking for what's inside the button. In this case:
Play...
So what I did was <button data-action="play">Play this video</button>
and in the JS I did following thing:
$('button').bind("click", function() {
player.api($(this).data("action"));
});

Javascript refresh webpage every 5s

I refrence the JS unlock right click script:
javascript:(function() { if(window.addEventListener) window.addEventListener(a, function (e) { for(var n=e.originalTarget; n; n=n.parentNode) n[ona]=null; }, true); window[ona]=null; document[ona]=null; if(document.body) document.body[ona]=null; } R("contextmenu"); R("click"); R("mousedown"); R("mouseup"); R("selectstart");})()
when you put the link in the url and enter, you can use right.
so I want to make a js link to put in the url and enter, the website will refresh every 5s.
javascript:(function() {
function refresh() {
window.location.reload(true);}
setTimeout(refresh, 5000);
})()
but I can't do that, please help.
because my English too bad, if u don't understand, ask me.
<meta http-equiv="refresh" content="5; URL=http://www.yourdomain.com/yoursite.html">
If it has to be in the script use setTimeout like:
setTimeout(function(){
window.location.reload(1);
}, 5000);
<script type="text/JavaScript">
<!--
function timedRefresh(timeoutPeriod) {
setTimeout("location.reload(true);",timeoutPeriod);
}
// -->
</script>

Jquery functionality not working when opening the page via AJAX.

I am trying to open a HTML page with jquery functionality in it via AJAX.
The page I am trying to open is:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"

style = 'easeOutQuart';
// if the mouse hover the image
$('.photo').hover(
function() {

Kindly help..

Scripts introduced by innerHTML won't be executed. You should use DOM methods, createElement, appendChild, to build the page. A simple example:
script = document.createTextNode("alert('Run')");
tag = document.createElement('script');
tag.appendChild(script);
div.appendChild(tag);

YouTube API — not firing 'onYouTubePlayerReady()'

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).

Using Youtube's javascript API with jQuery

I'm currently trying to use the YouTube API as part of a jQuery plugin and I've run into a bit of a problem.
The way the YT api works is that you load the flash player and, when it's ready it will send a call back to a global function called onYouTubePlayerReady(playerId). You can then use that id combined with getElementById(playerId) to send javascript calls into the flash player (ie, player.playVideo();).
You can attach an event listener to the player with player.addEventListener('onStateChange', 'playerState'); which will send any state changes to another global function (in this case playerState).
The problem is I'm not sure how to associate a state change with a specific player. My jQuery plugin can happily attach more than one video to a selector and attach events to each one, but the moment a state actually changes I lose track of which player it happened in.
I'm hoping some example code may make things a little clearer. The below code should work fine in any html file.
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="application/text+html;utf-8"/>

$.fn.simplified = function() {
return this.each(function(i) {
var params = { allowScriptAccess: "always" };
var atts = { id: "ytplayer"+i };
$div = $('<div />').attr('id', "containerplayer"+i);
swfobject.embedSWF("http://www.youtube.com/v/QTQfGd3G6dg&enablejsapi=1&playerapiid=ytplayer"+i,
"containerplayer"+i, "425", "356", "8", null, null, params, atts);
$(this).append($div);
});
}
})(jQuery);
function onYouTubePlayerReady(playerId) {
var player = $('#'+playerId)[0];
player.addEventListener('onStateChange', 'playerState');
}
function playerState(state) {
console.log(state);
}
$(document).ready(function() {
$('.secondary').simplified();
});
</script>
</head>

</div>
<div class="secondary">
</div>
<div class="secondary">
</div>
<div class="secondary">
</div>
</div>
</body>
</html>
You'll see the console.log() outputtin information on the state changes, but, like I said, I don't know how to tell which player it's associated with.
Anyone have any thoughts on a way around this?
EDIT:
Sorry, I should also mentioned that I have tried wrapping the event call in a closure.
function onYouTubePlayerReady(playerId) {
var player = $('#'+playerId)[0];
player.addEventListener('onStateChange', function(state) {
return playerState(state, playerId, player); } );
}
function playerState(state, playerId, player) {
console.log(state);
console.log(playerId);
}
In this situation playerState never gets called. Which is extra frustrating.
Edit:
Apparently calling addEventListener on the player object causes the script to be used as a string in an XML property that's passed to the flash object - this rules out closures and the like, so it's time for an old-school ugly hack:
function onYouTubePlayerReady(playerId) {
var player = $('#'+playerId)[0];
player.addEventListener('onStateChange', '(function(state) { return playerState(state, "' + playerId + '"); })' );
}
function playerState(state, playerId) {
console.log(state);
console.log(playerId);
}
Tested & working!
Im Using Jquery SWFobject plugin, SWFobject
It is important to add &enablejsapi=1 at the end of video
HTML:
<div id="embedSWF"></div>
Jquery:
$('#embedSWF').flash({
swf: 'http://www.youtube.com/watch/v/siBoLc9vxac',
params: { allowScriptAccess: "always"},
flashvars: {enablejsapi: '1', autoplay: '0', allowScriptAccess: "always", id: 'ytPlayer' },
height: 450, width: 385 });
function onYouTubePlayerReady(playerId) {
$('#embedSWF').flash(function(){this.addEventListener("onStateChange", "onPlayerStateChange")});
}
function onPlayerStateChange(newState) {
alert(newState);
}
onYouTubePlayerReady must be outside of $(document).ready(function() to get fired
I had this same problem and tried the accepted answer. This didn't work for me; the playerState() function was never called. However, it put me on the right path. What I ended up doing was this:
// Within my mediaController "class"
window["dynamicYouTubeEventHandler" + playerID] = function(state) { onYouTubePlayerStateChange(state, playerID); }
embedElement.addEventListener("onStateChange", "dynamicYouTubeEventHandler" + playerID);
// End mediaController class
// Global YouTube event handler
function onYouTubePlayerStateChange(state, playerID) {
var mediaController = GetMediaControllerFromYouTubeEmbedID(playerID);
mediaController.OnYouTubePlayerStateChange(state);
}
It's fairly nasty, but so is the current state of the YouTube JavaScript API.
Here is some other helpful/nasty code if you are using any kind of advanced prototyping patterns. This basically allows you to retrieve a "class" instance from the YouTube player ID:
// Within my mediaController "class"
// The containerJQElement is the jQuery wrapped parent element of the player ID
// Its ID is the same as the player ID minus "YouTubeEmbed".
var _self = this;
containerJQElement.data('mediaController', _self);
// End mediaController class
// Global YouTube specific functions
function GetMediaControllerFromYouTubeEmbedID(embedID) {
var containerID = embedID.replace('YouTubeEmbed', '');
var containerJQObject = $("#" + containerID);
return containerJQObject.data('mediaController');
}
function onYouTubePlayerReady(playerId) {
var mediaController = GetMediaControllerFromYouTubeEmbedID(playerId);
mediaController.OnYouTubeAPIReady();
}
Here's a nice article that goes through creating a class to wrap an individual player, including dispatching events to individual objects using a similar approach to that mentioned in a previous answer.
http://blog.jcoglan.com/2008/05/22/dispatching-youtube-api-events-to-individual-javascript-objects/
How about something like so:
var closureFaker = function (func, scope) {
var functionName = 'closureFake_' + (((1+Math.random())*0x10000000)|0).toString(16);
window[functionName] = function () {
func.apply(scope || window, arguments);
};
console.log('created function:', functionName, window[functionName]);
return functionName;
};
ytplayer.addEventListener("onStateChange", closureFaker(function () {
//place your logic here
console.log('state change', arguments)
}));
