JavaScript - Help With Frame Based Animation Code
Hi,
I'm trying to make something along the lines of a dynamic animated GIF. In other words, I'm trying to write a script to flip through images based on the current time. Before folks start suggesting other ways to do this, know that this is just a proof of concept. The reason for doing it this way is so that I can eventually control the animation either in response to interaction or external data queries (I'm looking into that js weather api). Code: int startTime = getTime();
float speed = 1.0;
image frames = new Array();
//load frames into array
for(int i = 0; i < 12; i++){
frames[i] = new Image(640,480);
frames[i].src = "frames/" + i + ".JPG";
}
//playback
int i = 0;
while(i < frames.length){
if( ((getTime()-startTime) % (speed*33)) == 0){
document.currentFrame.src = frames[i].src;
i++;
}
}
Thanks, Zach Similar TutorialsI' am trying to do a frame by frame animation, lik an animated gif. I am using svg (vector graphics) and IE9 has native support for svg. The code functions in every other browser but IE9 plays the animation once then nothing. If you would like to try and not have svg files you can use whatever gif,jpg or png just put an img-tag where i have embed. Code: <!DOCTYPE HTML>

Hi guys, I have a little experience in Javascript and would like to learn a bit more etc. I am currently working for a company which wants me create / find a image scroller using javascript and jquery. I found one which seems very suitable... I have customized the CSS and have coded it all up... The problem i'm having is that the image scroller is scrolling 3 images at a time. I would like it to scroller one at a time whilst showing all the images... Example scroller: [ pic 1] [pic 2] [pic 3] [pic 4] after scroll [pic 2] [pic 3] [pic 4] [pic 1] after next scroll [pic 3] [pic 4] [pic 1] [pic 2] and so forth. If you look at this code you will see what I mean... please help me learn and please help me complete this... im sure its just a little adjustment... but me not being too great at javascript... it makes me feel like im shooting in the dark. Thanks alot Code: <style type="text/css" media="screen">

Hi. I have a question about java script code. I'm creating a website with frames. Within the main page frame, there are tables in the main content page. When I created the website, it fit perfectly in the browser window of my smaller laptop. I just checked it out on my old G5 and the images/pages are too big and either cut off or scroll bars appear (which is not what I want) So I wanted to know what code I put in my files and where to put it? Also, what pages does it need to be in? the main frame index page? the specific pages that fit within the frames? some are images that load in the frames? would i need to create an .html for those and then have the .jpg load so that it can be resized? I need the main page to be resized to fit the browser as well as the pages in the frames to fit. Can you help? Thanks I need a code that will load multiple codes based on what minute it is. Example: If it's 12:31 it will load code A If it's 12:32 it will load code B (Lets just say there are only two codes) If it's 12:33 it will load code A If it's 12:34 it will load code B etc. I use to have this in a file somewhere, but over the course of the past few years I've misplaced it an am unable to find it. It would be much appreciated if I could get some help with this. I am using a web tracking tool called REinvigorate, which is great but doesn't give you the ability to exclude specific referring domains from the stats. However, their support guy told me that I can accomplish this by referencing the referring domain in a small script that only calls the tracking code when the referring site is not "This one we don't want in our stats". I only know C# and SQL, though, so I'm not entirely sure how to do this. Is this right? spreecommerce.com is the domain we want to exclude... <script type="text/javascript"> if (document.referrer.search("/spreecommerce/") != -1) { document.getElementById('iFrameId').src = '<trackingcode>'; } </script> Thanks! Austin guys help pls.. i need to pass the data in the textfields from the left frame to the textfields in the right frame of my frameset. (ex: dslnum of frame1 will be pass to txtDSLTN of frame2) frame1: http://www.mediafire.com/?hge1ws29mdhmu7e frame2: http://www.mediafire.com/?k83cb64wbpskw97 thanks in advance! Hi, Please i am not getting clear understanding of a javascript code to redirect user to a different web page based on the day of the week. Please i have search for many script and not getting clear understanding from their code.I have also try several code myself but nothing good has come from it. Please can someone help me and write a descriptive code for me to understand better.I really plead you and your to help me...but i belief the Lord God will bless you for your time helping me. looking forward to here from you. Thank you. Clement Osei I have a javascript controlling the display of a DIV that I did a while back that needs a bit more tweaking to add function to hide the DIV on specific holidays. As it is now, by default, the DIV is being hidden unless it is M-F between 8:00AM-6:00PM: Code: <script type="text/javascript">
onload=function(){
var rightNow = new Date();
var day = rightNow.getDay();
var hour = rightNow.getHours();
var minute = rightNow.getMinutes();
var formDisplay = 'none'; // unless we see otherwise
var forwardDisplay = 'block'; // unless we see otherwise
if(day==1 || day==2 || day==3 || day==4 || day==5) { // if chat is avalable on these days
if((hour>=8) && (hour<=17)) // if chat is avalable between these times
formDisplay = 'block', forwardDisplay = 'none';
}
document.getElementById('ChatForm').style.display = formDisplay;
document.getElementById('ChatForward').style.display = forwardDisplay;
}
</script>
Im assuming that I would just add more else if statements, but not really sure the cleanest way to assign specific dates using this format. Any help is appreciated I have a page called answersheet.html which I am popping up using a function called NewWindow; Code: <a href="javascript:myVoid()" onclick="NewWindow('/images/101online/practicetest1/listensubtest1/answersheet.html','PopUp','625','400','no',''); return true;">
It works fine. answersheet.html consists of two frames, the top frame containing a button with onclick="myprint()" to print out the bottom frame: Code: <script type="text/javascript">
function myprint() {
window.parent.bottom.focus();
window.print();
}
</script>
It does the job in Internet Explorer, but Firefox and Chrome only print the top frame with the print button! Is the function myprint() IE only coding? If so, what should I use? I want to create some type of seasonal feel on my Web page where there are falling leaves. I presently have 6 different gif images of leaves that I know I will probably have to load into an array. I also know that I will have to figure out the maximum width & height of the screen, which is different in Internet Explorer and other browsers. My goal is to load the leaves randomly as well using 'Math.floor(Math.random()*6)', if that is correct. Beyond that, I am lost on how to manipulate the Web page to make this animation occur. Any help would be appreciated. Thank you. Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

I have a picture of a pinwheel on my website that I want to spin onMouseover. Can this be done with JavaScript?
Hi, I have created an animation exercise for an eLearning lesson in a program that uses JavaScript as the scripting for a Windows executable. A retired social worker who creates these eLearning materials as give-away's to help people in the community improve health, it would be a big help to reaching more people if instead of a Windows executable version, the animation could be developed in a web page. A lot more people could view the eLearning and try this exercise which trains people in pacing their breathing. The animation has a 300X300 circle on the canvas with a couple of text input boxes and a start button. The JS < 50 lines of script, but since it was not developed for a web page, it has no tags and it depends on objects like the circle or button (or 2 audio files to create the inhale/exhale sounds) that were already placed on the canvas in the Windows executable program. I'm not very skilled using Dreamweaver CS5, but with help, reading, references can try to convert this JS into a web version, if it's possible. Not sure how to do this and would appreciate any help. I am adding a screenshot of the interface and the JS functions that are called by the start button. //JS: ( bar1 is the variable entered by the use as breaths per minute-BPM; //time1 is the exercise length; the variables initially are set as follows: //time1=15, //volume=100) var time1 function minuteTimer() { breakLoop = false stopLoop = false fork (calcBreathing) for (var i=0;i<time1;i++) { wait(60) breakLoop = true Submit.Show() Text122.Show() Text12.Show() TextInput22.Show() TextInput2.Show() Submit2.Hide() TextInput2.SetTransparency(0,false) TextInput22.SetTransparency(0,false) Text12.SetTransparency(0,false) Text122.SetTransparency(0,false) Text5.SetTransparency(0,false) Frame12.SetTransparency(0,false) Submit.SetTransparency(0,false) TextInput2.Enable(true) TextInput22.Enable(true) Debug.trace("\n minutes elapsed "+(i+1)+"\n") } stopLoop = true } function calcBreathing() { var bar2 = 60/bar1 for (loop = 0;loop<bar1;loop++) { mySound.Play(1,volume) Vector8.Scale(.5,.5, bar2*.3) mySound.Stop() wait (bar2*.05) mySound2.Play(1,volume) Vector8.Scale(-.5,-.5,bar2*.6) mySound2.Stop() wait (bar2*.05) if (breakLoop) break } breakLoop = false if (bar1 > 6) bar1-- if (!stopLoop) calcBreathing() } Any help appreciated. Thanks very much. Kind Regards, saratogacoach Hello readers! I made some animation code Code: for (var i = 1; i < 8; i++) {
var slc = ".s" + i;
$(slc).css(
{
'position':'absolute',
'top':'-300px',
'left':30*i*5,
'width':'100px',
'height':'300px',
'backgroundColor':'white'
});
};
$('body').click(function() {
for (var t = 1; t < 8; t++) {
var asd = '.s' + t;
$(asd).animate({
'top':'0px'
}, 100*t).animate({
'top':'-300px'
}, 100*t);
};
});
in html there are some div tags. So, question is - How to normilize queue of animation? You see that first box moves fast and the last one moves very slow to the end. I would like boxes to move proportionally in relation to the time. Could you give some recommendations about this stuff? I am having some difficulty with this project. It is supposed to be an animation of falling leaves. I am very new to arrays and JavaScript, so right off the bat I know that the arrays I have are not right, or are missing something else in order for it to function. Basically all I have for this project is a still picture of the leaves and that is it. If there is someone out there with some JavaScript expertise, could you tell me what I am doing wrong? Here is the code so far, I think it is too long. Code: <script type="text/javascript">

Hi, I will really appreciate if someone could take a look at my code below and inform me where I'm going wrong, because I can't seem to tell. The instructions a -the file starts with the text "Avalon Books" on the left edge of the page. -the text moves to the center of the page. -After the text reaches the center, the image file kids.jpg appears -Every two seconds thereafter, the image file is swapped with the next image file in the stack (there are 3 images in total). I am only posting the few relevant functions where the problem could be. All the other functions are working properly. I am new to JavaScript so any help will be really appreciated. Thank you This is the main file: Code: function placeObjects(){
var W = (0.5)*winWidth(); //gets the width of user's browser.
placeIt("avalon",0,0); //placeIt function is working fine.
placeIt("kids",W-75,100);
placeIt("fiction",W-75,100);
placeIt("nfiction",W-75,100);
setZ("kids",3); //setZ function is below.
setZ("fiction",2);
setZ("nfiction",1);
moveAvalon();
}
function moveAvalon(){
var x = xCoord("avalon");
if(x <= (W-125)){
shiftIt("avalon", 10, 0);
setTimeout("moveAvalon()",50);
}
else swapImages(); //if x is greater than W-125
}
function swapImages(){
showIt("kids");
showIt("fiction");
showIt("nfiction");
setTimeout("swapIt(kids,fiction,nfiction)",2000); //syntax could be wrong here?
}
</script>
</head>
<body onload="placeObjects()"> //calls the first function on load.
...............
</body>
</html>
and here is the second file that contains all the functions (I am posting 2 of those functions): Code: function setZ(id, z){
var object=document.getElementById(id);
object.style.zIndex="z";
}
function swapIt(id1, id2, id3){
var object1=getObject(id1);
var object2=getObject(id2);
var object3=getObject(id3);
var z1;
var z2;
var z3;
object1.style.zIndex="z1";
object2.style.zIndex="z2";
object3.style.zIndex="z3";
object1.style.zIndex="z3";
object2.style.zIndex="z1";
object3.style.zIndex="z2";
}
Hi, I created JavaScript animation and the picture after animation finished disappear. Could anyone tell me or point me how to resolve this kind of issue? I tested it in IE as well as Firefox.. I could send the code but it is quite long for posting, but the screenshots from before and after animation is finished are as below. thanks in advance for any help. trotsky I have a site with a lot of animated gifs and I was wondering if there was a way to (on page load) stop all gif animations (only show first image frame). Then when you click a link, it will animate the animated gifs.
I have created an animation API, which has an option for the 'effect' or animation type. Now i'm trying to produce a slow, fast slow effect using a sine wave but seem to be having some trouble! The code below is supposed to get the steps to calculate each frame by diving the usable part of the sine wave into the total frames. The code should then go on to calculate insert the relevant values into the frame variables, after which multiply them all so that they are the correct scale so that when the animation is running it simply looks up the value and applies it, no need for any processing. With an animation from 0 to 740 (px in this case) the function returns: 115, 228, 335, 434, 523, 598, 659, 703, 730, 740 Oh and just a quick addition the variable "end" will equal 740 in the case above, or whatever the end value is. Code: case "SFS":
var step = 90 / totalFrames;
var pi = Math.PI;
var raid = 0;
for (var i = 1; i <= totalFrames; i++){
raid = (i*step)*(pi/180);
queueFrameValue[topOfQueue][i] = Math.sin(raid);
}
var multiplier = end / queueFrameValue[topOfQueue][totalFrames];
for (var i = 1; i <= totalFrames; i++){
queueFrameValue[topOfQueue][i] = queueFrameValue[topOfQueue][i] * multiplier;
}
break;
Thanks! Anyone got any suggestions on techniques? The main one I find is to use translate to move the canvas around, which just seems odd to me. I don't even fully understand how it works. But the one I was looking at used clearRect. In examples given looked as though it had to redraw the canvas every frame. I'm just mucking around with a simple poker game, figured i'd have the table in one layer and anything that moves on a top layer? By doing that I could only clear each card as it moved around...yes? Anyone know of a better way of doing things? |
