JavaScript - Js Help For Edge/html5 Project
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 ) {

}
}
}
function drawFlip( flip ) {
// Strength of the fold is strongest in the middle of the book
var strength = 1 - Math.abs( flip.progress );

// How far the page should outdent vertically due to perspective
var verticalOutdent = 20 * strength;

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. Similar TutorialsHey, I have a drop down box that selects a project name. This is then taken to a javascript function that is supposed to fill in a read-only box with that name, but instead of filling it in with the project name, it fills it in with the project ID, which is how the sql database is set up. Each project has an ID, a name, and other values. Is there a way I can get the project name given the project ID in the javascript function?
I am a newbie in terms of website design and animation. I want to do a animation that can random show my image when I click the mouse . And I use Adobe Edge to do my animation. I used the javascript of Math.random() but it doesn't work. I think this methods is wrong. Can anyone give me some help??? Thank you. Ok... so I just downloaded the new Adobe Edge program for creating HTML5 websites. I was trying out a proof of concept for something I wanted to do on a site with a simple circle shape (will eventually be a soccer ball) rolling across the screen when clicked. The animation looks great, but it happens when the page loads, not when the image is clicked. Any suggestions?? Thanks! My HTML Code: <!DOCTYPE html>

Hello Folks, I installed a template on the following site and did not actually write the javascript dropdown menu seen at the top of http://sthomaslc.com/ The problem is that if parent list items Ministries and Parish Leadership have enough children, they expand out right off of the screen of low resolution setups. I am totally new to javascipt programming so excuse my ignorance when I ask how to make the children items to expand out left instead of right if it's detected that the menu has hit the right side of the browser window. Best Regards David I want to know how to move a character on the path when you click the left or right arrow, but also when the left arrow is clicked it will switch between 4 images, making it look as though the characters is actually walking left arrow = moves character to left on the path(walks to the left) right arrow = moves character to right on the path(walks to the right) up arrow = character jumps This is my original code, it draws a path something like this \____ ........................................................................................\ Code: function drawMap(){
// get the canvas element using the DOM
var canvas = document.getElementById('map');
// Make sure we don't execute when canvas isn't supported
if (canvas.getContext){
// use getContext to use the canvas for drawing
var ctx = canvas.getContext('2d');
// Stroked Path
ctx.beginPath();
ctx.moveTo(0,70);
ctx.lineTo(45,115);
ctx.lineTo(250,115);
ctx.lineTo(300,135);
ctx.stroke();
ctx.closePath();
} else {
alert('Your broswer does not support Canvas, We recommend getting the latest version of google chrome for the best quality');
}
}
Can anyone point me in the right direction? I'm keen to know what you guys think of this. In order to have HTML5 semantics and support for older browsers without Javascript enable I've written a little script that changes classes into node. For example <div class="nav"> would become <nav class="nav"> Code: //Adapt page to HTML5
function changeNodeName(element, newNodeName) {
var oldNode = element,
newNode = document.createElement(newNodeName),
node,
nextNode;
node = oldNode.firstChild;
while (node) {
nextNode = node.nextSibling;
newNode.appendChild(node);
node = nextNode;
}
for (var i = 0; i < oldNode.attributes.length; i++) {
newNode.setAttribute(oldNode.attributes[i].name, oldNode.attributes[i].value);
}
oldNode.parentNode.replaceChild(newNode, oldNode);
}
try {
var theBody = document.getElementsByTagName("body")[0];
var classNames = ["article", "aside", "command", "details", "summary", "figure", "figcaption", "footer", "header", "mark", "meter", "nav", "progress", "ruby", "rt", "rp", "section", "time", "wbr"];
for (var i = 0; i < classNames.length; i++) {
htmlFourElements = document.getElementsByClassName(classNames[i], theBody);
for (var ii = 0; ii < htmlFourElements.length; ii++) {
changeNodeName(htmlFourElements[ii], classNames[i]);
}
}
} catch(e) {
console.error(e.message);
}
Let me know what you think I want to have an example on web storage. I have an index.html page. On this page, there is a button which will go to another page, that is page1.html. On this page now, there is another button which will go to page2.html if clicked. Index.html > page1.html > page2.html Suppose if a user has already visited page2.html on the first time, how to make him/her goes directly on page2.html after clicking the button on index.html? The user must not again go to page1.html to get page2.html because he/she has already done that. I want to know how to store page sessions with HTML5 so that the user gets on his/her last visited page when he/she clicks the button. Thank. I followed a tutorial on Lynda for a simple HTML5 slideshow and altered it so that it doesn't auto play and has next and previous button controls. I can't quite figure out the previous button.

This doesn't quite work. If you click on the back button it goes forward one slide then back Then when you click the next button you have to click it several times before it will go forward again. Any help would be greatly appreciated 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">

Hi there! I found this code, in reply to someone's problem, on this forum. I have altered it to my own needs, as it's an excellent piece of code. However, I would like it to run under HTML5. I believe I need to add "canvas" code to do the same?? I have already changed the doctype! HTML heading etc., Can anyone help? Many, many thanks!! Code: <!doctype html>
<head>
<meta charset=UTF-8" />
<title>Crazy Rally - France</title>
<script type="text/javascript">
var frames = new Array();
//load frames into array
for(var i = 1; i < 417; i++){
frames[i] = new Image(480,320);
frames[i].src = "track" + i + ".png";
}
//playback
var currentFrameNumber = 1;
var fps = 30; // frames / second
const speed = 1000 / fps; // milliseconds
//var speed = 33;
function nextFrame( )
{
document.getElementById("display").src = frames[currentFrameNumber].src;
currentFrameNumber = ( currentFrameNumber + 1 ) % frames.length;
setTimeout( nextFrame, speed );
}
window.onload = nextFrame;
</script>
</head>

<img id="display" src="track1.png" width="480" height="320">

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? 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 Purmar 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> I 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 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!!!! 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 YD |
