JavaScript - Javascript Image Transitions
Can someone point me in the right direction to making custom javascript image slideshow transitions?
Similar TutorialsMy goal is to replace a 300px x 300px div with a random assortment of pictures, all being 300px x 300px. I however am not that great at JavaScript (I've taken a bigger bite than I can chew) and would love your guys' help. So far this is what I have for my JavaScript: Code: begin();
function begin()
{
setTimeout(newimage(),7000);
}
function newimage()
{
}
Which brings me to my first question: What's the best method of pre-loading images? And also, if the method is not through JavaScript, how would I reference the image from the JavaScript? My next step would be to transition between images. (Fading specifically.) I really like the fade transition here and I plan on using that in the site. How would I incorporate that into my code? I noticed he made the entire JavaScript code into one line, which is quite annoying. Thanks guys! Hi, I was wondering why in mozilla firefox the same image menu has different way of transition on different sites. If you use firefox and go to this link and then hover over different pictures you will get to know how it moves http://www.alohatechsupport.net/exam...ge-menu-2.html after doing that go to this link http://bloghutsbeta.blogspot.com/201...ting-main.html and hover over images and see how it moves. In both cases the transition effect is same but in one it is slow (hanging) while in other it is smooth. I didn't presented the Markup as the both are identical but still if you feel like let me know in comments I will edit it to provide you with as much relevant data as possible and required. Hi, I'm trying to work out some of the variables of a JQuery-based scripts I got he http://www.dreamcss.com/2009/04/crea...y-sliders.html Specifically I'm trying to work out how to change the delay between slide transition, whether I can disable the auto-transitioning or not (and how), and how to change the sliding speed of the images. Which variables do they rely on? Thanks for the help. Code: var $j = jQuery;
$j(function(){
slider.init();
});
var slider={
num:-1,
cur:0,
cr:[],
al:null,
at:10*845,
ar:true,
init:function(){
if(!slider.data || !slider.data.length)
return false;
var d=slider.data;
slider.num=d.length;
var pos=Math.floor(Math.random()*1);//slider.num);
for(var i=0;i<slider.num;i++){
$j('#'+d[i].id).css({left:((i-pos)*845)});
$j('#slide-nav').append('<a id="slide-link-'+i+'" href="#" onclick="slider.slide('+i+');return false;" onfocus="this.blur();">'+(i+1)+'</a>');
}
$j('img,div#slide-controls',$j('div#slide-holder')).fadeIn();
slider.text(d[pos]);
slider.on(pos);
slider.cur=pos;
window.setTimeout('slider.auto();',slider.at);
},
auto:function(){
if(!slider.ar)
return false;
var next=slider.cur+1;
if(next>=slider.num) next=0;
slider.slide(next);
},
slide:function(pos){
if(pos<0 || pos>=slider.num || pos==slider.cur)
return;
window.clearTimeout(slider.al);
slider.al=window.setTimeout('slider.auto();',slider.at);
var d=slider.data;
for(var i=0;i<slider.num;i++)
$j('#'+d[i].id).stop().animate({left:((i-pos)*845)},845,'swing');
slider.on(pos);
slider.text(d[pos]);
slider.cur=pos;
},
on:function(pos){
$j('#slide-nav a').removeClass('on');
$j('#slide-nav a#slide-link-'+pos).addClass('on');
},
text:function(di){
slider.cr['a']=di.client;
slider.cr['b']=di.desc;
slider.ticker('#slide-client span',di.client,0,'a');
slider.ticker('#slide-desc',di.desc,0,'b');
},
ticker:function(el,text,pos,unique){
if(slider.cr[unique]!=text)
return false;
ctext=text.substring(0,pos)+(pos%2?'-':'_');
$j(el).html(ctext);
if(pos==text.length)
$j(el).html(text);
else
window.setTimeout('slider.ticker("'+el+'","'+text+'",'+(pos+1)+',"'+unique+'");',30);
}
};
Hello, I am working on a page that has a jQuery full browser BG image and I am trying to also utilize a MooTools gallery. There seems to be some interference between the two JavaScripts as only one works (whichever one is last in order in the header of the HTML document). Links: http://www.courtneyhunt.com.au/press_bg.html http://www.courtneyhunt.com.au/press_gallery.html I am a complete novice with JavaScript so if anyone could help that would be great. Thank you in advance. Hi I've searched this forum and found nothing that fits my problem. I used Gimp. I have a map that I have split up into about 5 regions that are all linked to Google for now. (links to be changed later on). I selected the JavaScript tab an then typed into the mouseover box. Here is part of the code it produces in the .map file: <area shape="poly" coords="205,32,159,34,150,83,124,122,114,154,133,175,140,199,159,222,176,217,185,214,223,194,224,173 ,231,155,235,130,224,124,215,107,213,82,212,71" alt="google" onmouseover="img src="http://i42.tinypic.com/14oc0lj.jpg"" href="http://www.google.com" /> The " bit looks wrong so I took it out and it still doesn't do anything when I mouseover. I've tried linking it to a file within my website folders as well as hosted on the internet. Any ideas please? The links work but the mouseover effect doesn't.

I need to do image cropping through javascript(without jquery) my requirement is just to get the coordinates through some callback function whenever user crop the image and click an ok button please help me with some javascript code here http://www.javascriptkit.com/script/...2/3slide.shtml Hi i have the above image slideshow script running fine on a webpage can anybody tell me how i can get it to run a second time to show a second different slideshow on the same page? Ive tried editing variables but i cant work it out. would be much appreciated Ta I followed this tutorial to create a clickable image slideshow with javascript on a site's homepage. However, it appears that the javascript:slidelink() is still running beyond the intended area as some of my content below the container is now underlined as if it were a link, when it should not be. I can tell that the script is the issue because when hovering over the content it shows "javascript:slidelink()" but will not go to anything when clicked. Here is the code I'm using, which is placed in a Wordpress theme container: Code: <html>
<head>
<script type="text/javascript">
<!--
//preload images

image1.src="image1.png"

Can anyone spot what might be causing the issue? Thanks in advance! Hi guys I'm really stumped on this, and I haven't been able to find a tutorial online anywhere. I'm trying to create an XML news feed for a company's website I am currently building. I have created the XML, and gotten the text to display perfectly in the HTML by using javascript. Now I want to add a thumbnail image for each news story, to make updating simpler, I wanted the url for the thumbnail to be entered into the XML, from which the javascript could read and then display in the corresponding area in the HTML. Is this even possible? Every tutorial I get when I use the terms "Image" and "Javascript" gives me a tutorial for a gallery or a slideshow which is not what I want at all. Below is the javascript code, followed by the XML code; Code: <script type="text/javascript">

I am sure that you guys can help me solve this problem. Many thanks in advance!! Antonino folks., i need to popup image on image hover?the image should be placed just above mouse pointer? i tried to implement event.x,event.y.. but it is not positoning well in all browsers..?is css need to be used here or please give me javascript code... this is the code function Large(obj,id,e) { // this is div tag,inside div i am placing imagebutton.. var imgbox=document.getElementById("imgbox"); var imgbtn=document.getElementById('<%=ImageButton3.ClientID%>'); imgbox.style.visibility='visible'; imgbtn.src=obj; imgbox.style.left=event.x; imgbox.style.top= event.y; } thank you Not sure where to even start here. I am trying to build a a small JavaScript image gallery. As you can see in the jpeg image at the link provided, i want the user to be able to change the large image by clicking on the small thumbnails. The thumbnails will also have a roll over where they enlarge slightly. Complicated? I'm not a javascript expert, but i know enough by editing existing code and have saved a bunch of code i've modified. I've googled for javascript image galleries and looked through them but no success... I can understand the clicking on a thumbnail to change the larger image but what gets me is having the thumbnail on top of the larger..as well having a still image at the top left....some sorta layering? anyway some sorta help to get me started would be very helpful... http://www.rossow-web.com/test/RCC_Mockup.jpg thanks! Hello. I am having trouble with a simple image gallery with navigational buttons including "first", "next", "previous", and "last"; and making a drop-down archive menu. 1. For the most part, the image gallery works. The problem is that when a user clicks on "next", and then "prev", the last image is not displayed. On the other hand, if a user clicks "prev", and then "next" the last image is displayed(works normally). 2. The way I am displaying the last image, the function last(), is not efficient. It simply refreshes the page in order to display the last image. Basic overview: The images follow a simple standard: page1, page2, page3,...page64; they are in a subfolder "img". The function changeImage() changes the image from the prev, to the next. The image gallery displays the last image in the gallery; when a user clicks on 'prev' it goes to the previous image, and go to the next image when clicked on 'next'. If the current image is the last image, and the user clicks on 'next', it goes to the very first image. Here is the code (in the <HEAD> tags): Code: <script language="JavaScript"><!--
which_image_loaded = -1;
NUMBER_OF_IMAGES = 64;
current_comic = 0;
ImageNames = new Array;
ImageNames.length = NUMBER_OF_IMAGES - 1;
for (counter = 0; counter < NUMBER_OF_IMAGES; counter++){
file_number = counter + 1;
filename = ("../img/page" + file_number + ".png");
ImageNames[counter] = filename;
}
function changeImage(direction) {
which_image_loaded += direction;
current_comic = which_image_loaded + 1;
if (which_image_loaded < 0)
which_image_loaded = NUMBER_OF_IMAGES - 1;
if (which_image_loaded == NUMBER_OF_IMAGES)
which_image_loaded = 0;
if(current_comic <= 0){
which_image_loaded--;
}
document.myimage.src = ImageNames[which_image_loaded];
}
function first(){
which_image_loaded = 0;
current_comic = 1;
document.myimage.src = ImageNames[0];
}
function last(){
window.location='http://www.bearoncampus.com';
}
and in the <BODY> tags Code: <img src="img/page64.png" alt="New comic not available." name="myimage" width="725" height="275"> <form> <input type="button" value="FIRST" onClick="first()"/> <input type="button" value="PREV" onClick='changeImage(-1);' /> <input type="button" value="NEXT" onClick='changeImage(1);' /> <input type="button" value="LAST" onclick="last()" /> </form> My guess is the code is not working properly due to the initial values of the counter. Last, is there a way to display the current image "myimage.src" using a dropdown menu with each option value as each image? I have done this with window.location, but this only redirects to the image location. Much thanks. Any help is greatly appreciated. Hello All. I'm trying to create a file upload page with pre-uploading preview, and using JS to change the images src upon selecting a local file. this works great, but unfortunatelly only for some image files, even though files were taken by the same camera,the same size, and created on the same date. I can't figure out for the life of me what is going on. The Code : <script> function changeImage(newSrc) var str = newSrc.toLowerCase(); cImg=document.getElementById("chngImg"); cImg.src=str; </script> <HTML> <BODY BGCOLOR="#FFFFFF"> <FORM METHOD="POST" ENCTYPE="multipart/form-data" ACTION="UploadScript1.asp" rel="nofollow" target="newWnd"> File 1:<INPUT TYPE=FILE NAME="FILE1" onchange="changeImage(this.value);"> <INPUT TYPE=SUBMIT VALUE="Upload!"> </FORM> <div><img src="oren1.jpg" id="chngImg"></div> </BODY> </HTML> Best Regards Oren Pildus http://www.muffettandsons.com/specproductstest.html Follow the link above and click on the pic to the right to open the pop up image gallery. For some reason the thumbs do not appear in the left preview pane until a rollover of the preview pane slide bar. This only occurs in IE. Firefox and Chrome both show the thumbs when opened and work just fine. Any help would be greatly appreciated... Thanks Hello everybody. i need to know how can i draw lines over images using javascript libraries. i already did that using wz_jsgraphics library but what do i need next is to be able to move the drawn line and change its position or be able to delete it if i no longer need it . i need to treat draw lines as if they were objects in their common sense. how can i do that ? any help will be greatly appreciated. Hi guys, I already posted this but it hasn't been approved by a mod or the mods are all at lunch or something lol. I want to display an image using javascript instead of HTML (or use javascript to change the HTML code dynamically when an update is made). I have created an XML file, which contains text data which is displayed in HTML by using Javascript. What I am having trouble with is getting Javascript to grab the image URL from the XML file, and then display that image in the correct div. How does one show an image by using javascript? and how do you get javascript to get the url from the XML? The following is my Javascript code which grabs the text from the XML and displays it in the HTML; Code: <script type="text/javascript">
var xmlDoc;
<!--
if (window.XMLHttpRequest)
{
xhttp=new XMLHttpRequest();
}
else // Internet Explorer 5/6
{
xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET","SDS.xml",false);
xhttp.send("");
xmlDoc=xhttp.responseXML;
var x=xmlDoc.getElementsByTagName("NEWS");
i=0;
function display()
{
title=(x[i].getElementsByTagName("TITLE")[0].childNodes[0].nodeValue.fontsize("5").fontcolor("white").bold());
date=(x[i].getElementsByTagName("DATE")[0].childNodes[0].nodeValue.fontsize("2").fontcolor("white").bold());
stitle=(x[i].getElementsByTagName("STITLE")[0].childNodes[0].nodeValue.fontsize("3").fontcolor("white").italics());
story=(x[i].getElementsByTagName("STORY")[0].childNodes[0].nodeValue.fontsize("3").fontcolor("white"));
txt= title + "<br />" + date + "<br />" + stitle + "<br />" + story;
document.getElementById("show").innerHTML=txt;
}
//-->
</script>
And this is the XML file; Code: <?xml version="1.0" encoding="ISO-8859-1"?> <BULLETIN> <NEWS> <PIC>"newssmall.jpg"</PIC> <DATE>14/3/2010</DATE> <TITLE>News Story 1</TITLE> <STITLE>This is a short sentence to describe the story in brief</STITLE> <STORY>This is the text of the news story</STORY> </NEWS> </BULLETIN> So what I want to do is create a function that grabs the url (relative) from the PIC tag in the XML ("newssmall.jpg") and then uses this URL to display the image on the HTML page. This way, only the XML needs updating when updating the news section of the site. Thanks for helping if you can, Dan |
