JavaScript - Switching Image Back And Forth Using Onclick?
I want to create the form button similar to this:
http://www.customusb.com/quoteform-wref-flashdrives.php Im a designer and i m a total noob in javascript, would appreciate very much if you could be patient with me.... i use an OnClick to switch the image but the if else statement just doent let me switch back to the original image, i not sure where i have gone wrong... appreciate again if anyone could help me out... below are the html and js thumnails: http://img215.imageshack.us/f/73258715.jpg/ http://img35.imageshack.us/f/44225148.jpg/ Similar TutorialsI'm quite new to javascript and don't often understand what I'm reading, so the search results I found didn't seem to help me much. Being such, if this question has been addressed elsewhere, my apologies. On my site, I have a navigation pane with 4 links. Two of these links show collapsable submenus. When one clicks a link, I want the CSS class of that link to change. For the two "real" links, I've just changed the class on the page itself. For the two collapsible menus, I'm trying to employ javascript. Ultimately for these two links, I want the class to change when clicked, and change back when clicked again. Here's the code for the page: Code: <div id="navigation">
<ul>
<li><h3><a href="javascript:;" onclick="changeclass(this);" onmousedown="toggleSlide('slidemenu');" class="colmain">COLLAPSIBLE MENU 1</a></h3></li>
<div id="slidemenu" style="display:none; overflow:hidden; height:100px;">
<li><h4><a href="#" class="sub">SUBMENU LINK 1</a></h4></li>
<li><h4><a href="#" class="sub">SUBMENU LNK 2</a></h4></li>
</div>
<li><h3><a href="#" class="main">LINK 1</a></h3></li>
<li><h3><a href="javascript:;" onclick="changeclass(this);" onmousedown="toggleSlide('slidemenu2');" class ="colmain">COLLAPSIBLE MENU 2</a></h3></li>
<div id="slidemenu2" style ="display:none; overflow:hidden; height:100px;">
<li><h4><a href="#" class="sub">SUBMENU LINK 1</a></h4></li>
<li><h4><a href="#" class="sub">SUBMENU LINK 2</a></h4></li>
</div>
<li><h3><a href="#" class="main" >LINK 2</a></h3></li>
</ul>
</div>
Here's the javascript I'm working with, which I adopted from http://www.webdeveloper.com/forum/sh...d.php?t=167660 : Code: /*<![CDATA[*/
var colstatus;
function changeclass(obj)
{
if (colstatus) colstatus.className='colmain';
{
obj.className='colmainshow';
colstatus=obj;
}
else
{
obj.className='colmain';
colstatus=obj;
}
}
/*]]>*/
I have three questions about this. 1. Seeing as I've been working with javascript for a grand total of six days so far, could you explain the best way to make my code work? What's the significance of colstatus=obj? 2. The javascript works if I leave out the else statement. It will change the class after being clicked, but, of course, doesn't change it back. However, if I click the other collapsible menu, it will change as expected, but the first will revert back to the original class. Why is this happening? 3. Seeing as the code is adopted, I have no idea what /*<![CDATA[*/ and /*]]>*/ mean. Would you explain? Thanks in advance for your patience and answers! As a newbie, I've been combining scripts and adjusting them to create a page that allows viewers to choose from different visual elements of a leaf that will be used to search a database. There are rollovers for each anchor dropdown, and a center image that is in layers to "assemble" the leaf. But I've run into a logistical nightmare and I'm not sure which is the best way to handle this. if variations were slight, i would have no problem. But to show some characteristics I need to know what one or two underlying images were as well. In other words, if I am choosing borders, and I have a round image. The border would have to know to put a round scalloped border - not a square one. (And if somebody goes back to change the shape, I would need the border to automatically know to change to a square scalloped border) Can I build conditionals within the layers? Or does it need to be inline with the image? is there another way to do this before my script becomes a disaster when I try to accommodate for numerous variations. Can I get a snippet or two of code to send me in the right direction? maybe there's some precreated script for this? (I can dream!) I hope that makes some sense. Here's the page that I'm working on. http://www.mergecreate.com/test25n.html I have a site where i switch between two images using some JavaScript. What I need is to be able to set a session variable or something so that if someone selects shading on or off it sticks to that for the rest of the session. Any idea or even a point in the right direction. Do i need cookies or is there a simple way to do this http://www.tech4t.co.uk/territorymapping/pentagon/ I have a banner that has image navigation on the lower right. The navigation links are images which, when clicked, change the banner without reloading the page. The actual switching of the banner is working when each image is clicked. However, my problem is this: The page itself is long and must be vertically-scrolled to see the entire content. Because of the scrolling, the banner could appear anywhere vertically on the page. And whenever I click the banner navigation hrefs, the page "jumps" so that the banner is at the top. The page should really stay in the fixed position. I'm not sure how to set it up so that no matter where the banner section is on the scrolled page, that the page stays in the same position when the navigation is clicked. My href's in that navigation are set up as : <a href="#"></a> Do I need something in my script so that the page won't jump? Or am I missing something in the HTML? Hi, I looked around to see javascript codes on websites but had no luck in finding what I wanted... or I just don't know how to work with it I want to switch/replace image with other images by clicking on radio buttons. i have the html, but how can I make this work??? can anyone help me out? Code: <body> <p><img name="main" src="black.jpg" width="100" height="100" alt=""></p> <p> <input type="radio" name="red" id="radio" value="radio" onClick="display red in main image"> </p> <p> <input type="radio" name="blue" id="radio2" value="radio" onClick="display blue in main image"> </p> <p> <input type="radio" name="green" id="radio3" value="radio" onClick="display green in main image"> </p> <p> <input type="radio" name="yellow" id="radio4" value="radio" onClick="display yellow in main image"> </p> <p> <input type="radio" name="black" id="radio5" value="radio" onClick="this would this play the main image 'black'.jpg"> </p> </body> thanks for any help in advance! Hi, I want the image in the header of my website to move from left to right and back in an endless loop. The image width is larger than the width of the div which contains the image, so when the image moves to the right, the right end of the image has to disappear. When the image moves back to the left, the left end has to disappear. Now I know I can use the overflow: hidden; element in the CSS file to hide a part of the image. I found already several javascript scripts to move an image over the screen, but these scripts move the image only in 1 direction. I need it to go in the 2 directions in loop. Also these scripts require a position: relative; element to the image, so the hidden overflow of the div doesn't work. An example of this kind of script: Code: <body onload="moveRight()">
<div id="header" style="width: 1010px;height: 170px;overflow: hidden;">
<img src="images/header.jpg" id="header" style="position:relative;top:0px;left:0px; ">
</div>
<script type="text/javascript">
var userWidth = window.screen.width;
function moveRight() {
var pp = document.getElementById("header");
var lft = parseInt(pp.style.left);
var tim = setTimeout("moveRight()",100); // 100 controls the speed
lft = lft+3; // move by 3 pixels
pp.style.left = lft+"px";
if (lft > 50) { // left edge of image past the right edge of screen
pp.style.left = 0; // back to the left
}
}
</script>
</body>
Is there any way to improve this script to my requirements, or am I completely looking in the wrong direction? I am trying to get the images on this page to revert back to the original photo after hover releases. I am assuming this is a simple fix, but I am no programmer and just did this in dreamweaver. http://www.dataflurry.com/joey/ I know theres a lot of codes out there online for this but I cannot seem to get any of them to work for me. I am trying to make my layout for an item page for an online store. I'd like one big image, with one or 2 thumbnails under it which when clicked will switch the big image. Clicked, not mouseover. Lets say my big images would be REG1.jpg and REG2.jpg, the first being the image on the page that will switch. THUMB1.jpg and THUMB2.jpg being the thumbnails. Is there a simple way to do this or is the code a complete mess like I've been seeing on so many pages? I'd say I have an intermediate understanding of HTML and I've just started teaching myself javascript but I'm starting to fall off the wagon, I can't decipher the stuff coming up in these example codes. Any help would be thoroughly appreciated!! Hi guys.. Im looking to basically have an image which is a button with a value, and when i click the image, it gets replaced by another image with a different value. when clicked again it would return to the original image and value.. Is this possible? and if so, please help cos im terrible at javascript! Many thanks Here is my code for two tab images. Code: <a href="#page-2"><img src="/images/but02.png" style="margin-top:8px; float:left;"></a>
<a href="#page-1"><img src="/images/but01.png" style="margin-top:8px; float:left;"></a>
I need to have it so when tab '#page-2' is clicked it will change the image to '/images/but03.png' and when tab '#page-1' is clicked it will change the image to '/images/but04.png' ? Its basically to show which tab is active, one image is lighter then the other. Can anyone help ? Hello. I need some help with refreshing an image(cgi chart) onclick.

Hi guys, I'm new to javascript but cannot figure out a way to do something or even if its possible. On the site there is an image with some descriptive text to the side, here is the work in progess link to the site for an idea www.igrey.co.uk/nbe I want to be able to click the arrows and the text and images change so you can scroll through a couple of different projects Any help or advice would be greatly appreciated All the best, Ian I just started my javascript class two weeks ago and am having troubles already and my book is no help. My first assignment is having a list of country names and when you click the radio button next to the name the country flag pops up in a designated area for the image. I have tried a few different things but nothing is working. I have the list of countrys and the radio buttons but when i click the radio button the image doesn't pop up. Also, when i click another radio button they all stay selected. from my spry sub.menu tab, i'm trying to use "onclick" to post a new img in a specific div elsewhere on the page. <li><a class="MenuBarItemSubmenu" href="#">CPQC</a> <ul> <li><a href="#" onclick="document.getElementById('cpqcRange').src='images/cpqc/cpqcHot.png';">Hot</a></li> </ul> </li> <div id="cpqcRange"> <p> <img src="cpqcLocation.png" alt="cpqcLocation" name="cpqcLocation" width="504" height="360" id="cpqcLocation" /> </p> </div> i think i'm close, but something is wrong. can you just call up the div "cpqcRange" by name and slap a new img.src in there??????? cheers, Paul today's weather in Kalispell, MT, USA cold, brrrrr, not much snow, but it's coming soon it was about 18degF this morning Hi all, I can't seem to add an onclick event to an image. I'm sure I am doing something wrong as I am very new to Javascript. This is a part of my javascript code that is in the head and body of my HTML file: Code: <head>
<script language="JavaScript">
.....
.....
var redLocation0 = redArray[0]+".jpg";
....
....
function redClick( buttonLocation ) {
window.location = "http://www.yahoo.com/"
}
....
....
</script>
</head>
<body>
<table>
<tr>
<td>
<script language="javascript">document.write('<IMG SRC="'+ redLocation0 +'">'); onclick="redClick('0')";</script>
</td>
</tr>
</table>
</body>
The image that is displayed is not clickable, and therefore the function redClick cannot be called. Can someone please help me and tell me where I am going wrong here. I am kinda new to JavaScript. Thanks! Code: <img id="who" class="who" src="who.jpg" alt="Warriors Chosen For Battle" title="Warriors Chosen For Battle"> <img id="chosen" class="selector" src="selector.jpg" alt="Click for next image" title="Click for next image" onclick="chosen()"> <img id="ambassador" class="selector" src="selector.jpg" alt="Click for next image" title="Click for next image"onclick="ambassador()"> Code: function chosen()
{
document.getElementById("who").src="chosen_for_christ.jpg";
}
function ambassador()
{
document.getElementById("who").src="ambassador.jpg";
}
Yeah so basically when I click on one of the selector images I want it to change the value "who" images src value. I'm making an image selector, it works fine in IE, but every other browser it refuses to do anything. I am trying to add a border around the base they select and then when they select another one, I want the previous one to go away and then high light that one. This is my PHP code that outputs the bases: Code: $gender = $_GET['gender'];
// SQL Injection here?
$sql = "SELECT * FROM habases WHERE gender='".$gender."'";
$result = mysqli_query($cxn, $sql) or die(mysqli_error($cxn));
$baseCount = 0;
while ($row = mysqli_fetch_assoc($result))
{
$baseimage = $row['image'];
$basesOutput .= "<input type=\"image\" id=\"".$baseCount."\" src=\"http://www.elvonica.com/".$baseimage."\" onclick=\"baseBorder(".$baseCount.");return false;\" value=\"".$baseimage."\" name=\"base\">";
$baseCount++;
}
I have a baseCount so each image ID is unique. The baseBorder() is the function that will change the border. Here is the baseBorder() function: Code: var prevId;
function baseBorder(count)
{
if (prevId)
{
$("#prevId").style.border="none";
}
else
{
$("#count").style.border="2px solid #E8272C";
prevId = count;
}
}
Can anyone help me out since it's not working? hello friends I'm a newbie.. I need a little help. Im using big images in my website. I want a javascript to toggle the image size from "Original size to fit with resolution of screen" and vice versa. It should be onclick function like this <img id="blahblah" src="myimage.jpg" onClick="resize();" /> |
