JavaScript - Javascript Image Swap Help
So what I have to do is have 1 image on my webpage and a button. When the button is clicked the image needs to toggle back and forth between img1 and img2.
After searching I've found ways to do this using the image itself as a button. But I'm having trouble getting it to work with an input button. Any help would be greatly appreciated. Similar TutorialsHi guys, I have this little snippet of code that swaps a toggle image for news for a plus or minus sign showing if the div is open or closed. This code has worked before but i made a couple modifications today and it stopped working unexpectedly and i'm not sure why its failing. I am presetting the div tag with a plus sign with css and then modifying it with javascript. The problem i am having is that when the div tag has been opened it does not swap the image to min.gif anylonger. It remains max.gif. Here's the javascript code Code: var News_Images = new Array();
News_Images[0]="images/max.gif"
News_Images[1]="images/min.gif"
function DisplayNews(body,box,link,id){
$(body + " > div > .news_box").each(function(){
if($(this).css("display")=="block"){
$(this).slideToggle("slow");
}
});
$(body + " > div > a[class='open_button_closed']").each(function(){ // search and change the + / - images
$(this).css("background-image",'url('+script_path+News_Images[0]+')');//
});
$(body + " > div > a[class='open_button']").each(function(){
$(this).css("background-image",'url('+script_path+News_Images[0]+')');//
});
if($(body + " > div > #"+box+id).css("display")=="none"){
$(body + " > div > #"+box+id).slideDown("slow");
$(body + " > div > #"+link+id).css("background-image",'url('+script_path+News_Images[1]+')');//
alert("box =" + box + " id = " + id + " link =" + link);
}
}
And here is the html sample Code: <div class="recent_news_box">
<a onclick="DisplayNews('#display_recent','news_link','open_button',3); return false;" id="open_button3" class="open_button"></a>
<a class="link_block" href="">Some Title Text</a>
<div style="display: none;" class="news_box" id="news_link3">
<img class="front_image" alt="" src="" align="right">
<span class="date">Jul 21, 2009</span>
<div>Some Stuff to display here will be short text</div>
</div>
</div>
Thanks in advance. Ok so I have a problem which I previously thought I had solved. I am creating a JavaScript Toggle off and on panel and although I have the code sussed for the toggling function there is something off on the image swap function I currently have it set up on two panels, so the code is used multiple times, the problem is it changes both buttons each time rather that just the one that was clicked. Anyway let's see what you think Javascript: Code: <script type="text/javascript">
var imageURL = "../images/portfolio/open.png";
function changeImage() {
if (document.images) {
if (imageURL == "../images/portfolio/open.png") imageURL = "../images/portfolio/close.png";
else if (imageURL == "../images/portfolio/close.png") imageURL = "../images/portfolio/open.png";
document.images["img1"].src = imageURL;
document.images["img2"].src = imageURL;
}
}
</script>
HTML: Code: <a href="#" onclick="toggle_visibility('job1');"><img name="img1" src="../images/portfolio/open.png" onClick="changeImage();"></a>
<a href="#" onclick="toggle_visibility('job2');"><img name="img2" src="../images/portfolio/open.png" onClick="changeImage();"></a>
Any idea what I have done wrong and why it is changing both of the images ('img1' and 'img2') instead of changing them seperately as they are clicked ?? Hi everyone, I have a set of "buttons" that expand/collapse information onClick, using Javascript that look like this... Here is the CSS I used to create the look of the "buttons"... Code: div.btn_workshops {
background-image: url(../images/btn_workshops_mid.gif);
background-position: top left;
background-repeat: repeat-x;
cursor: pointer;
height: 22px;
margin-bottom: 1px;
width: 330px;
}
div.btn_workshops_lt {
background-image: url(../images/btn_workshops_lt.gif);
background-position: 0 0;
background-repeat: no-repeat;
height: 100%;
width: 100%px;
}
div.btn_workshops_rt {
background-image: url(../images/btn_workshops_rt.gif);
background-position: 100% 0;
background-repeat: no-repeat;
height: 100%;
padding: 3px 12px 0px 12px;
width: 100%px;
}
.hide {
display: none;
visibility: hidden;
}
.show {
display: block;
visibility: visible;
}
Here is the HTML that contains the "buttons" and the text that will appear when you click on the "buttons" to expand them. Keep in mind that everything collapses when you click on any of the "buttons" a second time. This is done, using Javascript. Code: <div class="btn_workshops" onclick="expandWorkshops('workshop1');flipArrow('arrow1')">

Here is the JavaScript I used to create the expand/collapse effect... Code: //Expand Workshops
function expandWorkshops(obj) {
var workshop = document.getElementById(obj)
if ( workshop.className != "hide" )
{ workshop.className = 'hide' }
else { workshop.className = 'show' }
}
Here is my problem. I added the downward, red arrows to give users a "hint" that the "buttons" will do some action if you click on them. By default, I have the arrows facing down to show that information will appear below the "button." Then once a user has expanded a block of information, I want the downward, red arrow to change to an upward, red arrow. I currently have that working, but it is only working "one way." In other words, when you click on any one of the "buttons," the arrow does change, but it does not change back to the default when you click on a "button" a second time to collapse the information. Here is what it looks like with one of the "buttons" expanded. As you can see, I was successfully able to change the downward arrow to an upward arrow after the information expanded below. This helps show that the text can collapse upward if you click on the "button" a second time. Again, my problem is I am unable to get the upward arrow to return to its default, downward arrow appearance. This is what it currently looks like when you click on the "button" a second time to collapse the information. As you can see, my expand/collapse effect works, and the text goes away, but I am unable to get the upward arrow to change back to the default, downward arrow. This is the function that I added to my JavaScript, which successfully changes the arrow from down to up onClick, but fails to return the arrow image to default when you click again. Code: function flipArrow() {
if ( document.images("arrow1").src = "static/images/arrow_down.gif" )
{ document.images("arrow1").src = 'static/images/arrow_up.gif' }
else if ( document.images("arrow1").src = "static/images/arrow_up.gif" )
{ document.images("arrow1").src = 'static/images/arrow_down.gif' }
}
This is the full JavaScript that includes the expand/collapse effect and the unsuccessful swap arrow effect so you can everything together. Code: //Expand Workshops
function expandWorkshops(obj) {
var workshop = document.getElementById(obj)
if ( workshop.className != "hide" )
{ workshop.className = 'hide' }
else { workshop.className = 'show' }
}
function flipArrow() {
if ( document.images("arrow1").src = "static/images/arrow_down.gif" )
{ document.images("arrow1").src = 'static/images/arrow_up.gif' }
else if ( document.images("arrow1").src = "static/images/arrow_up.gif" )
{ document.images("arrow1").src = 'static/images/arrow_down.gif' }
}
The flipArrow function I wrote is just my latest attempt. Believe me, I've tried all kinds of things, including "if else," "if else if," "if." I've tried Variables, getElementById, and switched out all different kinds of methods and ID's. No matter what, I can't seem to get any combination to work. Don't get me wrong. One of the previous methods I tried might have been the correct one, but I most likely did not write it correctly. I am no JavaScript expert at all. The code that I currently have was partly found on the Internet and partly modified by me after hours and hours of research and troubleshooting. I'm very proud that I was able to get this far, but I'm getting to the point where I am spending all day and night, every day, trying to figure this out. I always search forums before posting in them. This is probably the second time I've ever posted in a forum. I hope it helps. Sorry to ramble on. I just want to make sure you have as many details and samples as possible so I do not get any questions or confusion. Thanks for your help! I am hoping you guys can help me with this issue. What I am trying to do is fairly simple, depending on what option you select in the menu I want the picture to change to different picture. The code that I posted below works perfectly except for one problem. I need the option value to display the color name, and not have the image code in it. I have researched ways to do this without having to use "value" but I just can't find one that works. Can someone please help me? Thanks in advance for any help given! Code: function changeimg(){
document.getElementById('colors').src=document.getElementById('color_dropdown_options').value
}
Code: <label> <select name="color" class="dropdown_options" id="color_dropdown_options" onchange="changeimg()"> <option value="/images/thumbnails/image1.jpg">White</option> <option value="/images/thumbnails/image2.jpg">Blue</option> <option value="/images/thumbnails/image3.jpg">Green</option> </select> </label> Code: <div id="display"><img src="/images/thumbnails/image1.jpg" width="270" height="382" alt="" id="colors" /> Hi, I am a JavaScript novice, and appreciate any help you can give. For design reasons, we did not like the appearance of a still video on our web page. So I write a short little script to replace a picture that we selected, with the code for a flash player, once the image was clicked. The code works exactly as designed on IE and Chrome. It works *almost* as designed on Firefox and Safari -- but on those browsers the "fullscreen" button in the plugin doesn't work. It is *not* a problem with the FlowPlayer code. If I simply put the FlowPlayer code into a web page, it works fine. I think that somehow some browsers do not want to let the FlowPlayer expend outside of the JavaScript object box I created -- though that is just an hypthesis. If you have any insight or suggestions, I would appreciate it. The page is at http://sudval.org/test.html The code: Code:

Below is the routine I am using that when invoked swaps images for other images: Code: <script>
function swapImage(swapContName) {
if (swapContName == 'mainImage1') {
document.getElementById('mainImage1').src = 'L1Bswap.gif';
document.getElementById('hand1').src = 'handr.gif';
document.getElementById('help1_pic').src = 'answers2.gif';
document.getElementById('homework').src = 'spacer.gif';
document.getElementById('instruct').src = 'spacer.gif';
document.getElementById('instructflag').src = 'spacer.gif';
}
}
</script>
Fairly simple and works well. But one of the images I would like to vanish (using the empty spacer.gif) has a border: Code: <img id="instructflag" border="1" src="FLAG.gif" width="23" height="15" align="left"> It must have this black border, but when it gets swapped for a blank, I am left with the black square. Anyone have any idea how to vanish the border along with the graphic? (I have some vague idea that "border" is not used any more, but anyway...). Hey, I'm new to javascript, and I know there are a lot of tutorials out there. My only problem is that i'm finding it difficult to integrate stuff from different tutorials together. Basically, I want text links to swap the image on the website, but then want to allow a zoom function or lightbox function to the image that appears. I'm not best at explaining things so i've done an example below. After clicking the link, the image changes. i want to be able to do the zoom on the image that it's changed to. is this possible? any help would be much appreciated. http://www.jamesbutterworth.co.uk/untitled-1.html Hey guys, Im a little stuck with a JQ script im trying to create. First the html: Code: <div id="image_holder">
<img src="images/default.jpg" id="image_swap" />
</div>
<ul id="links" class="test">
<li><a href="#" name="images/01.jpg">Wall-E 2</a></li>
<li><a href="#" name="images/02.jpg">Joker 1</a></li>
<li><a href="#" name="images/03.jpg">Joker 2</a></li>
</ul>
What im trying to accomplish is: 1.) When the mouse enters #links I want it to create a bool staying true if it's in there false if it has left. 2.) if the mouse is: 2a) swap the current image loaded out with the new image to be loaded else: 2b.)swap the current image loaded out with the default image. I have several different attempts at this, this script below is a working attempt. But because im referencing the actual "a" attribute, whenever I goto hover on a new link, it will quickly show the default image... Code: jQ('#links li a').hover(
function() {
var img = jQ(this).attr("name");
var parent = jQ(this).parent().parent().attr("id");
jQ("#image_swap").fadeOut("medium", function() {
// if mouse is within the #link id dont show default image
if(parent === "links") {
jQ(this).attr("src", img);
jQ(this).fadeIn("medium");
}
// if the mouse is outside the #link id show the default image
})
},
function() {
jQ("#image_swap").attr("src", "images/default.jpg");
}
);
Also as a side note, before asking why im using the "name" attribute to store the URL of the image, it's because the href will be pointed to an actual page. I'm a designer and HTML/CSS coder only. I'd like to ask the community for the simplest solution on making an image swap to different image when the user clicks one of the many thumbnails. It's pretty standard gallery functionality, "click the thumbnail to see the big version". I'm hoping to get some JavaScript that is easy to configure even though I don't know how to write JavaScript. Here's a link to the page: http://clientzone.thermostudios.com/.../bouquets.html The thumbnails are on the left and the replicable image on the right. Thanks in advance. I need a script and HTML code for an image effect like this: http://www.saksfifthavenue.com/main/...11947&ev19=1:2 Something very easy, if possible. Thanks.
I have one image on a page and I am trying to mix 2 javascripts actions on that image: - the first one is an automatic daily change of images (3 different images in this example) - the second one is the display of the same image in bigger when the mouse is over it. The total of images are 6 (2 different sizes for 3 images). I have made a search but I didn't find the solution. Here is the code (the daily change works but not the rollover. Thank you to correct it or giving an other solution. (My level in Javascript: low) [CODE]<SCRIPT LANGUAGE="JavaScript"> function todaysPhoto(){ var i= 3 ; var todaysFoto=new Array(); todaysFoto[1]="img1_small.jpg"; todaysFoto[2]="img2_small.jpg"; todaysFoto[3]="img3_small.jpg"; var todaysPic=new Array(); todaysPic[1]="img1_big.jpg"; todaysPic[2]="img2_big.jpg"; todaysPic[3]="img3_big.jpg"; t=new Date().getTime(); var days=Math.floor(t / 86400000) % i+1; document.getElementById("todaysfoto").src="images/photos/"+todaysFoto[days]; function SwapImg(){ document.todaysfoto.src ="images/photos/"+todaysPic[days]; return true;} function SwapBack(){ document.todaysfoto.src ="images/photos/"+todaysFoto[days]; return true;} </SCRIPT> <body onload="todaysPhoto()"> <a href="" onmouseover="SwapImg()" onmouseout="SwapBack()"> <img name="todaysfoto" width="150px" height="100px" id ="todaysfoto" /></a>[CODE] Hey everyone, I'm just trying to figure out if it is possible to swap the pages background image when a button is clicked without refreshing the page? I've looked around and can't really find anything helpful. Any tips or pointers in the right direction would be much appreciated Thanks YD I have an on/off image piece of code: (probably out of date!) Code: <!--
var NN3 = false;
image1= new Image();
image1.src = "photo1.gif";
image1on = new Image();
image1on.src = "photo2.gif";
function on3(name) {
document[name].src = eval(name + "on.src");
}
function off3(name) {
document[name].src = eval(name + ".src");
}
NN3 = true;
function on(name) {
if (NN3) on3(name);
}
function off(name) {
if (NN3) off3(name);
}
// -->
My problem is that I am trying to add sound to the clicking and mousing out of the image. Without sound, it works (and works exactly the way I want it to) like this; Code: <a href="javascript:myVoid()" onmousedown="on('image1');" onmouseover="off('image1')">
<img src="photo1.gif" name="image1"></a>
Adding (flash)sound I can do this and it works OK too: Code: <a href="javascript:myVoid()" onmousedown="on('image1');mySoundObj1.TGotoAndPlay('/go','start'); return true;" onmouseout="off('image1');">
<img src="photo1.gif" name="image1"></a>
But what I want to occur is that a second "swish" sound happens onmouseout (in the red place below) but ONLY if the mousedown has already occurred: Code: <!--
...
function on(name) {
if (NN3) on3(name);
}
function off(name) {
[SWISH SOUND HERE]
if (NN3) off3(name);
}
// -->
I hope this doesn't read complicated. I know it's really a simple toggle with an if, but I've tried dozens of things to no avail. I have to replicate this many hundreds of times in a website...and I have to stick with flashsound (which I like anyway). Any help would be appreciated. I am working on a demo for a movie site, and 90% of everything seems cool. Here I am doing php.flushes, .htaccess caching and using PNGs to help with performance. I might start using another sub site to grab all the scripting from to increase performance, but it seems a tad bit slow at the moment. - There are a few issues one being when you click on X-Men and look at the gallery the images seem to flicker sometimes going from image to image. I am using a fade script I found and then using setTimeout() to give the fade script time to do its thing then call for a new image. Code: FadeOpacity(main_img_id, 100, 0, 600, 12);
setTimeout("updateGallery('"+target_arr+"','"+main_img_id+"')", 600);
- Also in the same area I am checking clientHeight after each image modifying the marginTop. The thing with that is the clientHeight only seems to update after the second function call. I tried using a setTimeout() but that didn't nothing. Code: document.getElementById(main_img_id).src = "assets/movie_images/"+arr[i]; img_height = document.getElementById(main_img_id).clientHeight; Any suggestions with improving image load performance, the clientHeight issue or the image flickering issue would be appreciated. Can someone tell me how to veiw this eval's out put? PHP Code: function doButtons(picimage) { eval("document['picture'].src = " + picimage + ".src"); } PHP Code: <?php // to change the image size within the web page function imageResize($width, $height, $target) { //takes the larger size of the width and height and applies the formula accordingly... //this is so this script will work dynamically with any size image if ($width > $height) { $percentage = ($target / $width); } else { $percentage = ($target / $height); } //gets the new value and applies the percentage, then rounds the value $width = round($width * $percentage); $height = round($height * $percentage); //returns the new sizes in html image tag format... //this is so you can plug this function inside an image tag and just get the return "width='$width' height='$height'"; } ?> <HEAD> <SCRIPT LANGUAGE="JavaScript"> <!-- Original: Ronnie T.

So I tried this code: Code: var image1 = document.getElementById("image1");
image1.onclick = image1_click ();
function image1_click () {
new_image= new Image
new_image = document.getElementById("image2");
new_image.src="image3.jpg"
}
But instead of replacing the image on click, from some reason it replaces image2 with image3 from start/load. What should I do to make this work? Thank you. When performing an Ajax request I want to change the submit button into a loading image and then swop it back again when the Ajax request is complete. I don't want a loading image anywhere else as on mobile phones it can't always be seen due to small screen size. I have grabbed the event (which references the form, is that right?) and I have something like this: Code: <button type="submit" name="name_can_vary">Search</button> event.name_can_vary.style.visibility = 'hidden'; //(obviously this isn't complete code but no doubt explains what I am talking about) ..which would hide the button and works exactly as I want to this point, but of course it does;t return when Ajax has completed or show the loading image. Ideally, instead of just hiding the button I want JavaScript to swop the button for the loading image. I suppose I could have extra HTML on every page that is made visible with the loading image but I would rather have JS do everything from here (saves editing all pages with submit buttons on). Thanks for any help. I have searched for information on this but so far no luck. site: http://www.brentpurton.com/TrueSteez go to the product page The problem: I have a set of images that have hover scrolling. The idea is that when you click on the thumbnail image at the bottom in the hover scroll area, a swap image behaviour will change the picture on the shirt. The real problem is that when I implement the swap image on the thumbnails and preveiw it. They no longer Hover Scroll, they just stay in 1 spot. They do however swap the image. here is what happens: http://www.brentpurton.com/TrueSteezSwap Any Help is apreciated. Thanks in advance I would like to add a submenu that pops up when the mouse moves over the first-level menu option. I succesfully added the submenu. However, now the image-swap script (the script that makes that the image that you see change as you move your mouse on the image) doesn't work anymore. Does anyone have any idea what I'm doing wrong?

I have added "Swap Image" into a page which already has a Drop Down Menu. However the Drop Down Menu stopped working. I know I have to remove the last line from the Drop Down Script ...window.onload=startList;... and integrate it into the <body tag> but I can't seem to figure it out. Someone please help... Below is the script for the drop down menu. // JavaScript Document startList = function() { if (document.all&&document.getElementById) { navRoot = document.getElementById("nav"); for (i=0; i<navRoot.childNodes.length; i++) { node = navRoot.childNodes[i]; if (node.nodeName=="LI") { node.onmouseover=function() { this.className+=" over"; } node.onmouseout=function() { this.className=this.className.replace(" over", ""); } } } } } window.onload=startList; Here is the page I'm trying to work with. http://sigautoparts.com/home-test.htm |
