JavaScript - Html5 And Js

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"> &larr;</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"> &rarr;</div>
                
        <!-- end slider section -->    
        </div>

Code:

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?


Code:

<div id="randomdiv1" class="article_example_div">
<embed src="Black Hawk Down - Music Video - Riot.mp3" width=25 height=25 autostart=false repeat=true loop=true></embed>
</div>

Hi, I worked on this website : http://www.kesslercareers.com/index.html and cannot find out why it does not work in IE while it works in other browsers. The small video does not play while the sound does. As far as I can see it works fine in FF and Chrome. Anybody any idea?

Thanks

I found a tutorial to create the HTML5 flip book.
I combined three Edge "projects" with the HTML5 flip book.
http://www.schrene.web44.net/Easter-2012/Book-A.html
I tried to adjust the z-index so that the butterfly would fly out of the book but nothing I tried worked..
Also I wanted the animations to start with each flip of the page...
I tried but I don't know enough javaScript to figure it out....
So I created a "cheesy" work around...
A very large div on the right side of the page that has the animations in a mouse out event.

Here is the page flip js:
Code:

(function() {
	
	// Dimensions of the whole book
	var BOOK_WIDTH = 880;
	var BOOK_HEIGHT = 460;
	
	// Dimensions of one page in the book
	var PAGE_WIDTH = 428;
	var PAGE_HEIGHT = 450;
	
	// Vertical spacing between the top edge of the book and the papers
	var PAGE_Y = ( BOOK_HEIGHT - PAGE_HEIGHT ) / 2;
	
	// The canvas size equals to the book dimensions + this padding
	var CANVAS_PADDING = 30;
	
	var page = 0;
	
	var canvas = document.getElementById( "pageflip-canvas" );
	var context = canvas.getContext( "2d" );
	
	var mouse = { x: 0, y: 0 };
	
	var flips = [];
	
	var book = document.getElementById( "book" );
	
	// List of all the page elements in the DOM
	var pages = book.getElementsByTagName( "section" );
	
	// Organize the depth of our pages and create the flip definitions
	for( var i = 0, len = pages.length; i < len; i++ ) {
		pages[i].style.zIndex = len - i;
		
		flips.push( {
			// Current progress of the flip (left -1 to right +1)
			progress: 1,
			// The target value towards which progress is always moving
			target: 1,
			// The page DOM element related to this flip
			page: pages[i], 
			// True while the page is being dragged
			dragging: false
		} );
	}
	
	// Resize the canvas to match the book size
	canvas.width = BOOK_WIDTH + ( CANVAS_PADDING * 2 );
	canvas.height = BOOK_HEIGHT + ( CANVAS_PADDING * 2 );
	
	// Offset the canvas so that it's padding is evenly spread around the book
	canvas.style.top = -CANVAS_PADDING + "px";
	canvas.style.left = -CANVAS_PADDING + "px";
	
	// Render the page flip 60 times a second
	setInterval( render, 1000 / 60 );
	
	document.addEventListener( "mousemove", mouseMoveHandler, true );
	document.addEventListener( "mousedown", mouseDownHandler, true );
	document.addEventListener( "mouseup", mouseUpHandler, false );
	
	function mouseMoveHandler( event ) {
		// Offset mouse position so that the top of the spine is 0,0
		mouse.x = event.clientX - book.offsetLeft - ( BOOK_WIDTH / 2 );
		mouse.y = event.clientY - book.offsetTop;
	}
	
function mouseDownHandler( event ) {
// Make sure the mouse pointer is inside of the book
if (Math.abs(mouse.x) < PAGE_WIDTH) {
if (mouse.x < 0 && (page - 1) >= 0) {
// We are on the left side, drag the previous page
flips[page - 1].dragging = true;
selPage=page-1;
}
else if (mouse.x > 0 && (page + 1) < flips.length) {
// We are on the right side, drag the current page
flips[page].dragging = true;
selPage=page;

}
}
// Prevents the text selection
event.preventDefault();
}

function mouseUpHandler( event ) {
for( var i = 0; i < flips.length; i++ ) {
// If this flip was being dragged, animate to its destination
if( flips[i].dragging ) {
// Figure out which page we should navigate to
if( mouse.x < 0 ) {
flips[i].target = -1;
if (selPage == page) page = Math.min( page + 1, flips.length );
}
else {
flips[i].target = 1;
if (selPage != page ) page = Math.max( page - 1, 0 );
}
}
flips[i].dragging = false;
}
} 
	
	function render() {
		
		context.clearRect( 0, 0, canvas.width, canvas.height );
		
		for (var i = 0; i < flips.length; i++) {
			var flip = flips[i];
			
			if( flip.dragging ) {
				flip.target = Math.max( Math.min( mouse.x / PAGE_WIDTH, 1 ), -1 );
			}
			
			flip.progress += ( flip.target - flip.progress ) * 0.2;
			
			// If the flip is being dragged or is somewhere in the middle of the book, render it
			if( flip.dragging || Math.abs( flip.progress ) < 0.997 ) {
				drawFlip( flip );
				
      
          
          
}

			
		}
		
	}

	function drawFlip( flip ) {

Here is the js for activating the Edge animations:
Code:

<script>
function playAnim1(){

          var comp = $.Edge.getComposition("page1");
          var stage = comp.getStage();
          stage.play("play1");
}

$(document).ready(function(){
          setTimeout(playAnim1, 1000);

}); 

function playAnim2(){

          var comp = $.Edge.getComposition("page2");
          var stage = comp.getStage();
          stage.play("play2");
}

$(document).ready(function(){
          setTimeout(playAnim2, 1000);

});
function playAnim3(){

          var comp = $.Edge.getComposition("page3");
          var stage = comp.getStage();
          stage.play("play3");
}

$(document).ready(function(){
          setTimeout(playAnim3, 1000);

});
</script>

Not sure if the things I want to accomplish with this are even possible???
If anybody has any help or advice I would greatly appreciate it.

I run Windows 7 and IE9, and I believe IE9 supports HTML5 Local Storage. But when I run this offline (locally) in IE9

Code:

<script type="text/javascript">

function testSupport() {  
if (localStorage)  {return "Local Storage: Supported"}
else  {
return "Local Storage: NOT supported";  
}
} 

alert ( testSupport() );
</script>

I get "LocalStorage: NOT supported".

Chrome returns "Local Storage: Supported"

My DOCTYPE is <!DOCTYPE html>


Other tests also fail in IE. Example:

Code:

localStorage.setItem("name", "Hello World!"); 
alert(localStorage.getItem("name"));

Above works in Chrome.
Any advice, please? Have I not configured IE9 properly?

I want to update the variables in the progress bar HTML5 has to offer.

Here is the function I have so far (It has been modified and shortened for the means of this post):
Code:

function calcProgress()
{
var num1 = Number(document.form.num1.value);
var num2 = Number(document.form.num2.value);
	Number(document.form.progress.value) = num1
	Number(document.form.progress.max) = num2;
}

This is the form:
Code:

<form name="form">

<input name="num1" onChange="calcProgress()" type="text" value="0" /> / <input name="num2" type="text" value="0" onChange="calcProgress()" size="1">
<br>
<progress name="progress" id="progress" min="0" value="0" max=""></progress>
</form>

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?

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.

Hi there,

I am just writing to see if I can receive some help regarding an issue I'm having?

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)

i want to know how to Upload images or videos through drag and drop (jquery or html5 tools)

Hey everyone

Just throwing this out there, is it possible to have an image displayed within a canvas moves around relative to the mouse's position?

For example, say I had a square canvas in the middle of the screen, and I had a small circle on that, could I have the circle position itself within the square canvas relative to the mouses position on the screen. So if my mouse was in the bottom left of the screen, the circle would be bottom left of the canvas?

Thanks

I am trying to create an Asteroids type game using JavaScript along with html5's canvas element for drawing. I have searched around and have looked at examples but I can't figure out what is wrong with my rendering that I do in the game loop that is run every frame. The problem appears to be only that the canvas is not cleared at the beginning of each frame but I feel there might be something wrong also. The code used and shown below only works in Firefox but not Google Chrome or Safari.

Here is a picture of what it renders in Chrome:

What is is supposed to look like and is in Firefox:


Here is my set up for drawing on the canvas:
Code:

var canvas = null;
var c2d = null;
//...
window.onload = init;
function init() {
	canvas = document.getElementById('canvas');
	c2d = canvas.getContext('2d');
	setInterval( step, 1000/FPS );
	//...
	//c2d.setTransform(1,0,0,1,0,0); // reset to identity <--Do I need this?
}

Below is the game loop function. Am I clearing the canvas correctly because it does not clear the screen? Also am I using the save and restore functions correctly? Each asteroid and player drawn is at a different of position and rotation so am I doing it correct to draw them?
Code:

function step() {
	//...
	canvas.width = canvas.width; //clear canvas PROBLEM

        //Things I have tried:
	//canvas.height = canvas.height; //clear canvas 
	//c2d.clearRect(0, 0, canvas.width, canvas.height);

	for (u=0;u<asteroids.length;u++) {
		c2d.save();
		asteroids[u].draw();
		c2d.restore();
	}
	c2d.save();
	player.draw();
	c2d.restore();
	
	c2d.strokeStyle = "#000000";
	c2d.stroke();
}

Below is the Asteroid and Player drawing functions. The Asteroid is a polygon and the Player is a triangle. Both rotate and are draw correctly but should I be passing a reference to the drawing reference?
Code:

function Asteroid_draw() {
	c2d.translate( this.x, this.y );
	c2d.rotate(this.angle);
	for (i=0;i<this.points_x.length-1;i++) {
		c2d.moveTo(this.points_x[i],this.points_y[i]);
		c2d.lineTo(this.points_x[i+1],this.points_y[i+1]);
	}
	c2d.moveTo(this.points_x[0],this.points_y[0]);
	c2d.lineTo(this.points_x[this.points_x.length-1],this.points_y[this.points_x.length-1]);
}
function Player_draw() {
	c2d.translate( this.x, this.y );
	c2d.rotate(this.angle);
	//Points {0,-12}{7,5}{-7,5}
	c2d.moveTo(0,-12);
	c2d.lineTo(7,5);
	c2d.moveTo(7,5);
	c2d.lineTo(-7,5);
	c2d.moveTo(-7,5);
	c2d.lineTo(0,-12);
}

Any help is appreciated.
