JavaScript - Javascript: Animated Image Height Changer
Hi there.
I'm relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>. The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed. Any help would be greatly appreciated. If anyone knows of similar examples online please send me a link. If you're interested in helping, please let me know if more information is needed. Thanks. Similar TutorialsI may be too close to this to see the answer but i have an image viewer with one big image and lots of little ones. What i need is that when you click on one of the smaller ones it grabs it's image src and sets the larger photo to that src. The small images are dynamic but the larger image will have a static id.
Hey, I'm working on a script that uses a function (called on click) to change the content of a div (called description) within the page. It contains an unordered list and list items. The first one has the class "show" and the ID "1", the second with just the ID "2", and so forth. (see code below). I am using jQuery to control the onclick function. the jQuery gets the current object with the "show" class. If there is no show class, it takes the first. It then puts a variable string together that represents the UL LI that is needed to be shown. Code: var descurrent = ($('div#description ul li.show')? $('div#description ul li.show') : $('div#description ul li:first'));
var desclass = '#description li#'+x;
Note: x is a variable transfered from the function change(x); where x is the ID that is to be shown HTML CODE: Code: <div id="description"> <ul> <li class="show" id="1">blahblah </li> <li id="2"> etc </li> </ul> The jQuery i'm trying to get to work is: Code: //Hide the current image
descurrent.animate({opacity: 0.0}, 1000)
.removeClass('show');
//Show new image
$(desclass).addClass('show')
.animate({opacity: 1.0}, 1000);
Note: the class "show" has a higer z-index Thanks in advance, Hope this can be resolved soon, been giving me headaches! Cheers, John Hi there, I just recently took over a site that has some java code on it I'm unfamiliar with. If you go to smalltowngossipmusic.com, you'll see what this code does. Go to the pages "Sounds" or "Travel", and once your mouse leaves the main image at the top of the page, you should see those pages shrink. This is some code that was implemented on the site (which is wordpress) in the header.php template. Here is the code: Code: <script type="text/javascript">
/* <![CDATA[ */
var $ = jQuery.noConflict();
$(document).ready(function () {
headerImage();
});
var speed = 500;
var origMT = 0, origHeight = '120px';
function expandHeader(obj) {
$('.headerImage').animate({height: '436px'},speed);
$('.headerImage img').animate({'margin-top': '-2px'},speed);
}
function shrinkHeader(obj) {
$('.headerImage').stop().animate({'height': origHeight},speed);
$('.headerImage img').stop().animate({'margin-top': origMT},speed);
}
function headerImage() {
origMT = $('.headerImage img').css('margin-top');
origHeight = $('.headerImage').css('height');
$('.headerImage img').css('margin-top','0');
$('.headerImage').css('height','436px');
setTimeout(shrinkHeader,speed*2);
$('.headerImage').hover(expandHeader, shrinkHeader);
}
/* ]]> */
</script>
If you look at the page source for each page, you'll see that there is nothing out of whack (at least, not that I can find). However, for some reason, this shrinking script only works on the two pages I mentioned - on every other page, it either doesn't work at all, or it only works about half-way. I have made sure the page.php and header.php templates both have accurate picture information in them, and can not find anything wrong anywhere. Is there any advice anyone here can give me on how to fix this? I've been doing html and css for awhile, but am relatively new to javascript and php, so am a bit out of my element on this. I'm willing to post any more code, snippets, whatever needed, just let me know what you need if you think you can help. Thanks, Brandon Hi I am trying to include an animated banner on my website but it wont work is there anyone out there who can look at my code and tell me where I am going wrong? Code:

I think the problem is that I have 2 onload functions in the body tag *<body onload="showCookies(); startBanner();">* does anyone know how I can fix this? Also when I put the Javascript into external files they won't work! but when I included the show cookies file in the html it works does anyone know where I am going wrong? I'm using some free javascript for my website and I'm trying to edit it slightly to behave the way I want on my site. Right now it works fine apart from one thing... It remembers the last active div that was open... then when you visit the site again or refresh the page... that div stays open and doesn't close when toggling the other animated divs like it is supposed to. How would I remove the last active div function or get it to close again when toggling other animated divs.. Thanks so much if you can help Here is the site: www.gjoob.terryarchonship.com here is where the last active div java is Code: showhide:function(divid, action){
var $divref=this.divholders[divid].$divref //reference collapsible DIV
if (this.divholders[divid] && $divref.length==1){ //if DIV exists
var targetgroup=this.divgroups[$divref.attr('groupname')] //find out which group DIV belongs to (if any)
if ($divref.attr('groupname') && targetgroup.count>1 && (action=="show" || action=="toggle" && $divref.css('display')=='none')){ //If current DIV belongs to a group
if (targetgroup.lastactivedivid && targetgroup.lastactivedivid!=divid) //if last active DIV is set
this.slideengine(targetgroup.lastactivedivid, 'hide') //hide last active DIV within group first
this.slideengine(divid, 'show')
targetgroup.lastactivedivid=divid //remember last active DIV
}
else{
this.slideengine(divid, action)

Plz help me. Thnx in advance Hi, on my site, I have added Style 1 and Style 2 in my menu at the top right http://www.thisisworthing.com/default.php# when I click on Theme 2, it doesn't work?! please help! I have this working on my other site: http://www.mypubspace.com what am i doing wrong?! Hi, I am no very little when it comes to Javascript but I have seen a few sites using pre populated text boxes for login forms. So Username and password appears in the boxes to save space. The code below works fine onload of the site in all browsers, everything also works fine in firefox but ie the following doesn't seem to work. When a user clicks to enter their password in i.e. it doesn't change the form to password characters so input plain text. Also when you click out of either box it doesn't seem to re-populate the boxes with my Username or Password text. Any help would greatly be appreciated. Code: <script>
function HideLabel(txtField){
if(txtField.name=='myusername'){
if(txtField.value==txtField.defaultValue)
txtField.value = '';
else
txtField.select();
} else if(txtField.name=='mypassword'){
if(txtField.value==txtField.defaultValue){
txtField.value = '';
txtField.type = 'password';
}
else{
txtField.type = 'password';
txtField.select();
}

Hi. I have a JavaScript that resizes an image held within an Iframe. It works perfectly, BUT only works if there is an alert box in the code. /*Image resizing scripts - Dependant on page size!*/ /////////////////////////////////// function Im_Resize() { var imheight = 550; /*Change the IFrame CSS*/ iframeheight = imheight + 15; /* +15px for the x-axis scroll bar*/ var IFrame = document.getElementById('MainFrame'); IFrame.style.height = iframeheight + 'px'; alert('after iframe size - before im change'); /*Change the Image CSS*/ var innerdoc = IFrame.contentDocument || IFrame.contentWindow.document; Image1 = innerdoc.getElementById('MainImg1'); Image1.style.height = imheight + 'px'; } If I take the alert box out the code just doesn't work?? I thought that it was that during the loading of the page an element hadn't been loaded yet, but a delay doesn't work either. If I press 'ok' on the alert box too quick it doesn't work either. In terms of HTML this script is run whenever the page is loaded and is also fired when a click event is detected on one of the divs on the page. Any help would be great Ed Can someone tell me why this short script won't work? <script type="text/JavaScript"> <!-- function timedRefresh(timeoutPeriod) { var number = rand(7); if (number == 1) { var bgcss = "theme1.css"; } else if (number == 2) { var bgcss = "theme2.css"; } else if (number == 3) { var bgcss = "theme3.css"; } else if (number == 4) { var bgcss = "theme4.css"; } else if (number == 5) { var bgcss = "theme5.css"; } else if (number == 6) { var bgcss = "theme6.css"; } else if (number == 7) { var bgcss = "theme7.css"; } document.write('<link href="bgcss "'+ 'type=text/css rel=stylesheet>'); } // --> </script> </head> <body onload="JavaScript:timedRefresh(10000);"> hey guys i downloaded the 'Content Slider v2.4', and this has a feature which will save a cookie used to remember and recall the last content viewed by the user when they return to the page. (click here for more information on the script.) the only thing is that this is made for pages with URLs such as: Quote: www.mysite.com/gallery_album_1/content.php but my URLS are set out like: Quote: www.mysite.com/content.php?gallery_album_1 is there a way to make to so the cookie remembers the page via the "php?gallery_album_1" part instead of the "content.php" part. i need it to be like this simply because i have multiple galleries coming from the oe page, eg: Quote: www.mysite.com/content.php?gallery_album_1 www.mysite.com/content.php?gallery_album_2 www.mysite.com/content.php?gallery_album_3 the main code of the js is as follows: Code: //** Featured Content Slider script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 2nd, 08'- Script rewritten and updated to 2.0.
//** June 12th, 08'- Script updated to v 2.3, which adds the following features:
//1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.
//2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).
//3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.
//** July 11th, 08'- Script updated to v 2.4:
//1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")
//2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.

as far as i can see, the parts of the code which are about the cookies are labeled "enablepersist" thanks guys Hi! I installed the Animated Information Bar found on http://www.javascriptkit.com/script/.../infobar.shtml Now there is a option to display the bar once per session but this isn't working... Code: infobar.setfrequency('session') //Uncomment this line to set information bar to only display once per browser session!
Anyone has installed this bar and knows why this isn't working? I use IE8 greetings Jardin Holland Hello This is brilliant and good to work with, there is one issue i have if someone can help please. I have used example 4 bacuase it visually does exactly what i need, however there is one little problem i cant solve. I copied the div and now have 2 collapsible divs next to each other, which nearly do exactly what i need. I have lined up the 2 divs next to each other they both open, but the one on the left pushes the right one out to the right and i don't know how to do that. here is the code thanks the animatedcollapse.js is too long to put but can be found here http://www.dynamicdrive.com/dynamici...edcollapse.htm Code: <script type="text/javascript">
animatedcollapse.addDiv('jason', 'fade=1,height=80px')
animatedcollapse.addDiv('kelly', 'fade=1,height=100px')
animatedcollapse.addDiv('michael', 'fade=1,height=120px')
animatedcollapse.addDiv('cat', 'fade=0,speed=400,group=pets')
animatedcollapse.addDiv('dog', 'fade=0,speed=400,group=pets')
animatedcollapse.addDiv('rabbit', 'fade=0,speed=400,group=pets,hide=1')
animatedcollapse.ontoggle = function ($, divobj, state) { //fires each time a DIV is expanded/contracted
//$: Access to jQuery
//divobj: DOM reference to DIV being expanded/ collapsed. Use "divobj.id" to get its ID
//state: "block" or "none", depending on state

I have an animated gif of a door opening on my site. The animated gif is triggered onclick. (It's triggered only when the user clicks on a certain part of the door, hence the image map). This is the current code: <img src="img/door_admin_static.gif" width="229" height=401" alt="admindoor" usemap="#admin" name="animate"> <map name="admin"> <area shape ="rect" coords ="65,165,236,501" onClick="document.images.animate.src='img/door_admin.gif'; return true" href ="admin.html" rel="nofollow" target="_self" alt="admin" /> </map> What is supposed to happen is that after the user clicks, the animation of the door opening runs, and then the user is taken to the page linked to that door (in this case, admin.html). As it is now, the user is taken immediately to the admin.html page, so they never get to see the animation run. I need some kind of code that makes it so that the user is taken to the admin.html only after the animation is complete. Any help would be greatly appreciated!! Hey guys, I'd like to think this is fairly simple but unfortunately my knowldege of jquery is limited to using prebuilt scripts and changing a few variables to get what i need. I created a drop down menu with a slide down/up animation for submenus, which worked out just as I wanted. I ran into troubles though when trying to add a nested menu to the drop down, but with a slide animation going from left to right. I'm sure my explanation isn't very clear, so please take a look http://www.palousehillscomputing.com...rop/index.html The nested submenu I am speaking of should only open when hovering occurs on the 'Item 01' link, but as you can see it also opens when hovering over the buyers link. Secondly, my attempt to slide from left to right on this ul is not working. It seems to be sliding down even though this was not defined in the code. I've tried playing around with it for a while now and can't seem to figure this out so I'd appreciate if someone pointed me in the right direction. Thanks Hello, i wanna make animated news bar like the one in the top of site alibaba.com, so how can i do that, anybody have any kind of tutorial for any thing like this please ? thanks Hi, I searched the web for a button that can be animated, as well as dynamic. but I couldn't find one, so I decided to try my hand at creating one. My method is similar to a post made by Bram2: http://codingforums.com/showthread.php?t=153326, however, I have found my code to be unreliable and it doesn't apply only to the area where the table is, instead of spreading across the screen. The reason for trying to create a button this way is because I'm lazy, I don't want to create a new button in a graphics editor, spending hours trying to make it uniform with the rest of the buttons on the page, every time I want a new button. Doing it this way will also enable to have buttons with mulitple lines of text. I am fairly new to javascript, so I am wondering if anyone can give me a hand making it more reliable or pointing me to a script that has already been created. I put the button Here instead of filling the post with code. Please look at it before telling me it can be done with the <button> tag, because I tried before posting here. thanks, grayatrox Edit:I have managed to get the code to do what I wanted it to do, and more efficently too. Old code is commented out in the orginal webpage. This is a working example on how to impliment the buttons. javascript: Code: /*
Notes:
- Each button MUST have a unique name.
- You may need to create a secondary function that the button can activate like I did with the go(url) function below.
- Email me (grayatrox) at 238atrox@gmail.com for bugs, or to suggest improvements.
- Yes I know tables within tables is bad, if you read through my code carefully you will see where I am talking about.

Does anyone have an explanation for why animated .gifs might not animate in FF, Chrome, etc.? Only IE does it right for me. I suspect it might have something to do with tables squeezing the graphic (if the .gif is inside a table with a 100% width cell... but even giving the cell with the .gif a width doesn't seem to help.) Is it true? I realise tables are not best used for this purpose, but did this also happen in the good old tables days? I am trying to do what I thought was a very simple animated menu. I have a heading at the top of a website - which is just a png. I have a menu that is simply a div with a few options on it arranged horizontally. There's no submenus, it's just a very simple horizontal list. All I am trying to do is to hide the menu and then when you mouseover the heading, it will drop down. When you mouseout, it will move back up. It would be great if it faded in as it moved down too. Am sure it's probably very simple, but I've looked all over Google and I can't find a simple solution that doesn't do X, Y and Z that I don't want or need in this project. I just need a very simple script that I stand half a hope of understanding! |
