JavaScript - Javascript Session Image Switching
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/ Similar TutorialsAs 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 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/ 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! 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? I'm trying to allow the user to change the stylesheet of my website. I can change the stylesheet on a page by page basis (eg. from red style to blue style) but once the user navigates to a different page the stylesheet resets back to the original setting. For example, when the user visits the site first its set to the red style, they can change it to blue but when they navigate to another page the style goes back to red again where as I want the style to stick across pages. Does anybody know how I can sort this out? I assume I'll have to edit my javascript but Im not very good at javascript so any help would be great! HTML Code: <html>
<head>
<link href="red.css" rel="stylesheet"
type="text/css" title="red" media="screen" />
<link href="green.css" rel="alternate stylesheet"
type="text/css" title="green" media="screen" />
<link href="blue.css" rel="alternate stylesheet"
type="text/css" title="blue" media="screen" />
<script type="text/javascript">
function changeStyle(title) {
var lnks = document.getElementsByTagName('link');
for (var i = lnks.length - 1; i >= 0; i--) {
if (lnks[i].getAttribute('rel').indexOf('style')> -1 && lnks[i].getAttribute('title')) {
lnks[i].disabled = true;
if (lnks[i].getAttribute('title') == title) lnks[i].disabled = false;
}}}

There are two pages, folder/india.html folder/usa.html and dropdown menu in each page to switch between india and usa pages. india.html page sells in INR and usa.html in USD with links to shopping carts for each currency. link1(INR) link2(USD) Except the link and the currency information(selling price), contents in both the pages are same. So here comes the problem. Google hates duplicate pages! I am looking for a solution where, a single page In That Page, a dropdown menu to select currency As the currency is selected, without page reload, the link to shopping cart and the pricing also should be changed according to the selected currency. So Single page should be able to handle both the currencies. Kindly suggest me with codes as I am new to javascript.

Hi, I am making a small software which will require activation. My problem is when I activate my software after checking the key through my website I want to enter some information in registry of the user. Now my problem is when I check the value through my website how can I return after verification to the local computer. is it possible if I create a session variable or some other type of variable (not sure what type) and then read that variable on user computer. If that matches I will enter the code in registry. Code: document.cookie = "score=400";
var x = document.cookie ;
alert("Time Up");
window.location.href = "main.php?option=insert_result&result=" + x;
In main.php I have a code that will save data on database. My question is why is that it saved something like score=200; PHPSESSID=m5v9qp5c9trcmfi9mso91b7nh5. All I want is 200 to be saved hello everybody, here I'm asking for help again. sorry for that in advance. anyhow, I have the following code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

I want the lightbox window open only once a day for every unique visitor on my website. I understand I should use some sort of cookie implented, but I dont really understand how to. Thanks in advance, daniel. Hi, I have a website where the user can navigate different categories by tab. The problem is, when they're on a tab other than the default one and they refresh the page or click to another page, it puts them back on the first tab. I know this can be solved by using a session cookie of some type, I just need some help on implementing it into my site. http://www.thatswhyimbroke.com/ - so you can see what i'm talking about. If you look at the different tabs: Price High, price low, food & drink, etc. I want the user to be able to go to one of those, click to page 2 or refresh, and still be on that tab. Any help would be much appreciated! I have been looking all over the web for a solution, because my website displays funky in safari. To fix this i figured i'd tell users that if they are using safari, then using javascript, i could tell them a message. Originally i tried detecting safari then displaying a message. But i couldn't ever find a browser detection for safari. So i thought wait.... If i could: 1. get a javascript alert saying my message. 2. time that message alert frequency by a session, say 10 days? or even every browser session... Then i could solve my problem. However i can't figure out any of this. So if anybody would be willing to help, i'd be very grateful. Hi Forum, to develop a "Digital Signage" applikation we need: 1) After loading the (main) html page get all the pages (.html, .pdf, .xls, .jpg) as members of the paylist. - Is there a way to get the appr. 15 pages into the browser (as DOM Objects) ? Or rather to load in 15 iFrames ? 2) The mentionde pages should be displayed in a certain order (in ca. 20 sec tact). - A possible solution would be to hide / unhide. Any other wy ? Thanks in advance Michel I'm a amateur and I've just coded this little script. What it does is quite simple, once you click on the 'theBox' div, it switches from one class to another. I can't help having the feeling that this could have been coded in a lot more simple way than the way I've coded. So I thought that maybe you guys could help me out. (Oh, and by the way, the script works fine in FireFox and IE). Code: <script>
function setDivClassName(string){
document.getElementById("divClassName").innerHTML = string;
}
function theBoxOnClick(){
var classes = new Array();
classes[0] = 'zero';
classes[1] = 'one';
classes[2] = 'two';
var currentClassName = document.getElementById('theBox').className;
var currentClassIndex;
var nowGoTo;
for(var i = 0;i <= classes.length-1;i++){
//alert(classes[i]);
if(classes[i] == currentClassName){
currentClassIndex = i;
nowGoTo = currentClassIndex + 1;
}
}
if(classes[nowGoTo] == undefined){
nowGoTo = 0;
}
document.getElementById('theBox').className = classes[nowGoTo];
setDivClassName(classes[nowGoTo]);
}
</script>
<style>
.zero{width:100;height:100;background-color:black;color:white;padding:10;border-style:solid;border-color:red;border-width:2}
.one{width:100;height:100;background-color:yellow;color:red;padding:10;border-style:solid;border-color:red;border-width:2}
.two{width:100;height:100;background-color:red;color:yellow;padding:10;border-style:solid;border-color:red;border-width:2}
</style>
<body onLoad="setDivClassName('zero')">
<div id="theBox" class="zero" onClick="theBoxOnClick()">
This DIV's Class is <div id="divClassName"></div>
</div>
Hi, I have two versions of a script: version A gets used on a visitor's first round, where the page is dynamically altered; if the visitor wants to do another round, I need to switch to version B. I could load both versions initially, but that seems overkill. Any suggestions ? I'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! So I had the orginial code just switch images, I was under the impression I could use "var clientData" to make an array. However this is not working out the way I had hoped. Any help or explanation, greatly appreciated. It's very sloppy now! Don't judge. Here is my Javascript: Code: <script type="text/javascript">

];

"This is Data for Client 2";
"This is Data for Client 3";
"This is Data for Client 4";
"This is Data for Client 5";
"This is Data for Client 6";
"This is Data for Client 7"
];
var currentMain = 0;
var currentMainT = 0;
function Prev()
{
return ShowMain(currentMain-1);
return ShowMainT(currentMainT-1);
}
function Next()
{
return ShowMain(currentMain+1);
return ShowMainT(currentMainT+1);
}
function ShowMain(which)
{
currentMain = which;
currentMainT = which;
if ( currentMain < 0 ) currentMain = 0;
if ( currentMainT < 0 ) currentMainT = 0;
if ( currentMain > imgList.length-1) currentMain = imgList.length-1;
if ( currentMainT > clientData.length-1) currentMainT = clientData.length-1;
document.getElementById('mainImg').src = imgList[currentMain];
document.getElementById('mainText').src = clientData[currentMainT];
var PD = document.getElementById('Pg');
var PD2 = document.getElementById('Pg2');
if (PD != null ) PD.innerHTML = 'Image '+(currentMain+1)+' of '+imgList.length;
if (PD2 != null ) PD2.innerHTML = (currentMainT+1)+' of '+clientData.length;
return false;
}
onload = function() { ShowMain(0); }
onload = function() { ShowMainT(0); }
</script>
Here is my area I am showing it.

I got my script to work. I created buttons with in the script, put them in a div, and used appendChild to add the div to the page. This all works and the style sheets switch, however I want to add a cookie, so when the user returns to the page it displays with the style sheet they were using last. I can't figure out how to grab which style sheet the user selected, to add it to the cookie. I have included the code for the switching. Code: function addEvent(object, evName, fnName, cap)
{
if (object.attachEvent)
object.attachEvent("on" + evName, fnName);
else if (object.addEventListener)
object.addEventListener(evName, fnName, cap);
}
addEvent(window, "load", makeStyleButton, false);
var allStyles = new Array();
function makeStyleButton()
{
var allLinks = document.getElementsByTagName("link");
for(var i = 0; i<allLinks.length; i++)
{
if((allLinks[i].rel == "stylesheet" ||
allLinks[i].rel == "alternate stylesheet") &&
allLinks[i].rel.title !="")
{
allStyles.push(allLinks[i]);
}
}

styleButton.value = allStyles[i].title + " view";
styleButton.title = allStyles[i].title;

styleButton.onclick = changeStyle;
styleBox.appendChild(styleButton);

styleBox.style.width = "125px";
styleBox.style.cssFloat = "right";
styleBox.style.styleFloat = "right";
styleBox.style.margin = "5px 5px 10px 10px";

I am not looking for someone to give me the answer, I am just looking for a push in the right direction, so to speak. I seem to be going around in circles with this problem. Thank you for your time. Heres a link to the code in question http://www.scccs.ca/~W0049698/JavaTe...erlocktxt.htm# when the leftPos variable is used in the moveSlide() it somehow turns into Nan. Cant figure out why and have been racking my brain over this for a long time now.. Any help would be greatly appreciated the problem is at the end of the code(scroll to the bottom) ======================================================= Code: window.onload = makeMenus;
var currentSlide = null;

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. |
