JavaScript - Html5/javascript Video System
Similar TutorialsI am new to javascript (I started learning it today) so please explain it for newbies. I am trying to get the amount of video (in seconds) buffered already by the client and the whole duration of the video. Then, I divide them to get the precentage which was buffered so far. I have no problem storing the durating using: Code: var duration = document.getElementById('vid').duration - returns "12.6" (seconds) I am struggling with getting the buffered time. I tried: Code: var buffered = document.getElementById('vid').buffered This one returns "[object TimeRanges]". From what I understood this is some kind of an object (Like an array?). I tried returning "buffered.length" and I get "1" back. Please explain how I can do this. thanks Hi, From my experience with HTML5 video so far (which isn't much), Firefox seems to switching to the "HAVE_ENOUGH_DATA" state too soon which is causing very choppy playback while the video is buffering. Is there a way to start the loading of video as soon as the page loads instead of waiting for the user to press play? I don't mean "autoplay", I want the video to start buffering as soon as the page loads without it playing. Thank you. Hello, I am coding a slider for my portfolio which has divs that slide when you click either the arrow keys or the numbers below the slider's frame. I just can't figure out how to change the javascript/css file so that the current slide number, (the little numbers below the image), becomes a different color when you actively view it, so that it indicates to users number they're currently on. Thanks for help! Here's a draft of what it looks like so far in the front end with my grids still in place: HTML file: Code: <div id="slider" class="span-24 last"> <div id="slide2Left"> ←</div> <div id="slideFrame"> <div id="slideBoard"> <!-- the slides --> <div class="slidePoint"> Slide 1 Goes Here </div> <div class="slidePoint"> Slide 2 Goes Here </div> <div class="slidePoint"> Slide 3 Goes Here </div> <!-- end slideBoard --> </div> <div id="slideReference"></div> <!-- end slideFrame --> </div> <div id="slide2Right" class="last"> →</div> <!-- end slider section --> </div> Javascript code Code: // JavaScript Document $(document).ready(function(){ var slideTime = 700; var currentSlide = 1; var totalSlides = $("#slideBoard > div").size(); var slideWidth = $('#slideFrame').css('width'); var slideAmount = parseInt(slideWidth); function slideLeft(){ if(currentSlide > 1){ $("#slideBoard").animate({ left: ['+='+slideAmount, 'swing'] }, slideTime ); currentSlide += -1; } } function slideRight(){ if(currentSlide < totalSlides){ $("#slideBoard").animate({ left: ['+=-'+slideAmount, 'swing'] }, slideTime ); currentSlide += 1; } } function slideTo(slideNumber){ ///* slideNumber = parseInt(slideNumber); slidePos = slideNumber -1; var p1 = $('#slideBoard'); var position1 = p1.position(); var p2 = $('#slideBoard div:nth-child(' + slideNumber + ')'); //alert(p2.html()); var position2 = p2.position(); var slideFor = (-position1.left) - position2.left; //alert('p1: '+ position1.left + ' p2: '+ position2.left + ' Sliding: '+slideFor); $("#slideBoard").animate({ left: ['+='+slideFor, 'swing'] }, slideTime ); currentSlide = slideNumber; //*/ } $('#slide2Left').click(function(){ slideLeft(); }); $('#slide2Right').click(function(){ slideRight(); }); $(document).keydown(function(e){ if(e.keyCode == 37){ //alert( "left pressed" ); slideLeft(); return false; } if(e.keyCode == 39){ //alert( "rigt pressed" ); slideRight(); return false; } }); //# Slide Reference Tool for(i = 1; i < (totalSlides+1); i++){ $('#slideReference').append('<div class="slideNumber">'+i+'</div>'); } $('.slideNumber').click(function(){ slideTo($(this).html()); }); $(".slidePoint").touchwipe({ wipeLeft: function() { slideRight(); }, wipeRight: function() { slideLeft(); }, min_move_x: 20, preventDefaultEvents: true }); }); CSS Code Code: /* CSS Document */ #slider { position: relative; margin: 79px 0 50px 0; height: 500px; padding-bottom: 50px; border-bottom: 1px solid #9B9B9B; } #slideFrame { width:870px; left: 40px; min-height:460px; height:460px; overflow:hidden; position:relative; border:#CCC solid 0px; } #test { width:30px; min-height:460px; height:460px; overflow:hidden; position:relative; border:#CCC solid 0px; } #slideBoard { position:absolute; top:0px; left:0px; width:3000px; min-height:400px; margin:0px; padding:0px; background: #ccc; opacity: .3; } .slidePoint { width:870px; min-height:400px; height:410px; display:inline-block; margin:0px; padding:0xp; float:left; } .slidePoint p { padding:5px; } #slide2Left, #slide2Right{ position:absolute; top: 200px; bottom: 5px; cursor:pointer; width:20px; height:20px; color:#9B9B9B; border:#9B9B9B solid 1px; border-radius: 5px; padding:3px; text-align:center; display: inline-block; } #slide2Right{ left: 920px; } #slideReference { position:absolute; width: 770px; min-height:10px; bottom:5px; left:50px; text-align:center; } .slideNumber { border-radius: 2px; background:#929292; color:#ffffff; cursor:pointer; display:inline-block; padding:3px; margin:3px; text-align:center; min-height:15px; min-width:15px; } I have a code that will randomly select a div from a list and inside of that div i want there to be a sound file. How would I use html5 and javascript to make it so that when a user clicks a button it would play whatever sound was associated with that button?

I have written this application: http://bit.ly/dOHwhp - It allows the user to make melodies and change the speed of playback. It uses HTML5 and JavaScript. What I'd really like to do is have the ability for the user to save the melody in some respect. At the moment, I am using a parse harsh method. I thought potentially the user could save the #... and then load it from the URL. I have a method of loading it from the URL but no current way of 'saving' it and loading the saved version, as such. I have a feeling it would be far more advanced but, I would love to have a download feature like they have on this site: http://patternsketch.com/ Could anyone help out? This is my JavaScript file as it stands (although all files can be discovered in the source code of the page) Code: // ===== VARIABLES ===== var isPlaying = false; var curNote = 0; var curTempo = 100; // ===== FUNCTIONS ===== // playTune: Play the next note! function playTune() { if (isPlaying !== false) { var nextNote = 60000 / curTempo / 4; // Turn off all lights on the tracker's row $("#tracker li.track").removeClass("active"); // Light up the tracker on the current track $("#tracker li.track.col_" + curNote).addClass("active"); // Find each active note, play it var tmpAudio; $(".playBar[id^=control] li.track.active.col_" + curNote).each(function(i){ tmpAudio = document.getElementById($(this).data('sound_id')); if (!tmpAudio.paused) { // Pause and reset it tmpAudio.pause(); tmpAudio.currentTime = 0.0; } tmpAudio.play(); }); // Move the track forward curNote = (curNote + 1) % 16; } // if (isPlaying) } // playTune // Make a new hash function buildHash() { // Start it var newhash = ''; // For each track, check and add in a 0/1 as appropriate $(".playBar[id^=control] li.track").each(function(i){ newhash += $(this).is('.active') ? '1' : '0'; }); // Separate it newhash += '|'; // Now, toss in the note newhash += $('#temposlider').slider('value'); // Check and see if we really need to update if (location.hash != '#' + newhash) location.hash = newhash; } // buildHash // Read in our hash function parseHash() { if (location.hash.length > 0) { // Split it up, work it out, removing the actual hashmark var pieces = location.hash.substring(1).split('|'); // Set the lights var lights = pieces[0]; $(".playBar[id^=control] li.track").each(function(i){ // Make sure we haven't exceeded if (i >= lights.length) return false; // Check our location, turn on class if need be if (lights.charAt(i) == '1') { $(this).addClass('active'); } }); // Set the tempo if (typeof pieces[1] !== 'undefined') { $('#temposlider').slider('value', parseInt(pieces[1])); $('#tempovalue').innerHTML = pieces[1]; curTempo = parseInt(pieces[1]); } } } // parseHash // Clear it! function clearAll() { $(".playBar[id^=control] li.active").removeClass('active'); } // Run on DOM ready $(document).ready(function(){ // Process each of the audio items, creating a playlist sort of setup $("audio").each(function(i){ // Make a self reference for ease of use in click events var self = this; // Make a sub-list for our control var $ul = $('<ul id="control_' + this.id + '" class="playBar">'); $ul.append('<li class="header">' + this.title + '</li>'); // Add 16 list items! for (j = 0; j < 16; j++) { var $li = $('<li class="track col_'+j+'">'+self.id+'</li>') .click(function(){ $(this).toggleClass('active'); buildHash(); }) .data('sound_id', self.id); $ul.append($li); } // for (i = 0; i < 16; i++) // Append it up $('<li>').append($ul).appendTo('#lights'); }); // Bind up a click for our button $("#soundstart").click(function(){ if (isPlaying === false) { // Start the playing! curNote = 0; isPlaying = setInterval(playTune, 60000 / curTempo / 4); // Change our display this.innerHTML = "Stop"; } else { clearInterval(isPlaying); isPlaying = false; $("#tracker li.track").removeClass("active"); $("audio").each(function(){ this.pause(); this.currentTime = 0.0; }); this.innerHTML = "Play"; } }); $('#clearall').click(clearAll); $('#reload').click(parseHash); // ===== Misc ===== // Build or read the hash if (location.hash == '') { // I was building this at load - but now, no, just to be safe //buildHash(); } else { parseHash(); } // Show our value, now that we've built off of the hash $('#tempovalue').html(curTempo); // Make our tempo slider $('#temposlider').slider({ 'value': curTempo, 'min': 30, 'max': 170, 'step': 2, 'slide': function(e, ui) { curTempo = ui.value; $('#tempovalue').html(curTempo); if (isPlaying !== false) { clearInterval(isPlaying); isPlaying = setInterval(playTune, 60000 / curTempo / 4); } }, 'stop': function(e, ui) { buildHash(); } }); }); I can play a sound on my local machine using the following code, but when I upload to a server the same code it does not play. I cannot work out why, the link below gives the code. The multi channel code is he http://www.storiesinflight.com/html5/audio.html I installed Firebug and insepcted the Net components and can see that the .wav files are being sought out but returning a 404 error. This would be fine, however the path being sought is correct. Clicking link does'nt play the sound, but removing the file and paring back to the directory brings you to the directory on the server and clicking the file does play the sound. The code works locally, and I simply cannot see what could be causing the issue in the server versions on both Firefox and Chrome. On all my html 5 pages of http://www.countyfairgrounds.net I have a drop down javascript menu for selecting a state. The thing has worked for years fine. However in switching to html5 the validator will not validate it. The are saying the option tag is obsolete. First I don't java, I do html5 and css3 currently. Ca anyonepoint me to a script dropdown that I can cut and paste - that will validate?
Sorry if this is the wrong forum for this question. I get confused about what forum to post a question in with regards to DHTML technologies since they are all frequently used together. Anyhoo, heres my question. I've recently discovered an interesting behavior. When I mouse over a nested element it triggers the 'onmouseout' event handler of the parent element. Take the following code snippet, for instance: Code: <table> <tr> <td onmouseout="window.alert('you moused out of td');"> <img src="image0.gif" style="height:50px; width:50px;" /> </td> </tr> </table> In the code snippet above, the 'onmouseout' event handler executes when you mouse over the image nested inside the <td> element. I wouldn't have thought this would be the appropriate behavior since from my perspective the mouse is still inside the <td> element. Can someone make comments on this. Thank You. Edit: I've discovered that mousing over a nested element causes both an 'onmouseout' and an 'onmouseover' event for the parent element. They are called back to back. Seems a little bit of an odd sequence of events but maybe it makes sense in the grand scheme of things. Yeah, right. How could I make it so that instead of seeing a embed object you would just see a input button that says play. I do not need my users to be able to pause them. I really didn't know where to start with the javascript but i do have the html5 Code: <audio controls="controls"> <source src="BlackHawkDown-MusicVideo-Frontline.wav" type="audio/wav" /> <source src="BlackHawkDown-MusicVideo-Frontline.mp3" type="audio/mpeg" /> Your browser does not support the audio element. </audio> THANKS!!!!

Hi everyone, I am trying to make an image mask using javascript. The basic idea is that the image on the canvas will appear as a black box. When the user hovers over the image a small part of it is revealed. I have attached a picture as an example because its quite hard to explain! Any help would be appreciated! Thanks, Luke I need to be able to drag an image from one browser window to a form text input in a different window, populating it with the image file name. I can do this easily, except that the result is the whole url, and I only want the filename to be inserted. In other words, it inserts http://www.path/path/file.jpg, but I just want to end up with file.jpg. I believe the file object .name property holds the info I need, but I don't know how to populate the input field with it. Any help appreciated. Hey all. I want to figure out how to make a new video pop up like this site I'm about to show you. Go to this link, then click on "Watch HD Video". You see how a new video pops up in the same window?

If any of you know how to achieve the exact same thing on that site, please share your knowledge with me! Hi all, How can I insert ads on html5 video tag before the main video plays?

Is anyone able to help out pleaseeeeee, I've never coded javascript before so Im not sure how to fix this. thank youu I am using joomla, and have a tabbed menu at the top, which has different articles embedded within. I have embedded a flash video inside each article. The problem is that if i play a video and then switch to the other tab (article) without pausing the video, the video keeps on playing. And if i try to play the video in the other article, then both videos start playing. I want to stop the first video from playing as soon as I switch to the new tab. There are a lot of different files which are included in the page, so If I know where to place a particular code within the source of the final rendered webpage, I will be able to place it at the right point in a particular file. thanks the website link is: http://tinyurl.com/ycg4tcm hi, I have created a flash video that work on a php table (like php-nuke), this is seen well on my PC, instead with various screen the video size is not good.
