JavaScript - Conditionals Nightmare On Image Switching
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 Similar TutorialsI 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 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/ 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! I am somewhat a noob at js/jquery so I wasn't sure exactly how to do this. Think I just need a push in the right direction. Basically I'm trying to validate a form (jquery validation) with a couple of conditionals based on a selection box. So I have: Code: <form id="info" class="validate">
<select id="select">
<option value="senior">Senior Citizen</option>
<option value="adult">Adult</option>
<option value="child">Child</option>
</select>
<input type="text" name="age" id="age" class="required" minlength="1" maxlength="3" title="age group">
</form>
I'm trying to validate that if the user has selected "Senior Citizen" then their age must be 65 or older (and validate the adult/child ages as well). I hope to get this all in ajax so it would be checking it live. Thanks for the help! Hey All, I've been poking away at what should be very simple code, but is becoming a nightmare. I have an iframe that the user uses to enter certain information, the iframe loads contiguous urls that do server side scripting and store information, so a total of 12 php files are run through until the user comes to the end of the information gathering session. I then want to give them the option to go back and review the information they gave me, OR submit the information (which I already have anyways). All I want the submit button on this last document to do is to set the style of the div that contains the iframe to display='none'. I have tried everything I can think of to do it, but I can seem to get the darn thing to call an element from the parent window on the inside. I've used "window.parent" and "parentNode" and they absolutely don't work. Any help would be greatly appreciated. I have a nested if that is not working, well I have two which are pretty much the same code apart from one has more conditions. The one with the least does not work. It is basically a quick password checker to see if the typed password matches the previously typed and then display an image according. Code: function checkPass(id){
var pass = document.getElementById(id).value;
if(pass == "")
{
notValid(id);
}
else if(id == "pwd2" && pass !== document.getElementById("pass").value || document.getElementById("pass").value == "")
{
notValid(id);
}
else
{
isValid(id);
};
};
If it is blank it calls notvalid and if the second if flags it calls notvalid however if it is ok then it does not do the else. Any ideas?? Thanks. 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 ? 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>
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 7"
];

document.getElementById('mainText').src = clientData[currentMainT];

return false;
}
onload = function() { ShowMain(0); }
onload = function() { ShowMainT(0); }

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]);
}
}
var styleBox = document.createElement("div");
for(var i =0; i<allStyles.length; i++)
{
if(allStyles[i].rel == "stylesheet")
{
allStyles[i].disabled = false;
}
else
{
allStyles[i].disabled = true;
}
styleButton = document.createElement("input");
styleButton.type = "button";
styleButton.value = allStyles[i].title + " view";
styleButton.title = allStyles[i].title;
styleButton.style.width = "125px";
styleButton.style.fontSize = "12px";
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";
var sourceDoc = document.getElementById("content");
sourceDoc.insertBefore(styleBox, sourceDoc.firstChild);
}
function changeStyle()
{
for(var i = 0; i<allStyles.length; i++)
{
if (allStyles[i].title == this.title)
{
allStyles[i].disabled = false;
}
else
{
allStyles[i].disabled = true;
}
}
}
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. 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" />

var lnks = document.getElementsByTagName('link');

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. Thanks a lot i have image button i need to display image .if the size of the image button is 100*100 and image size is 50*50 .the remaining space of the image button should be empty.the image should not stretch. can any one guide me i am new to programming Thanks in advance!!! I have gotten my script to do exactly what I want it to do with one exception. I have some thumbnail images that people can mouse over and the actual image is 100px by 75px. That is what I use for my thumbnail and they reside in www.website.com/images/thumbs/image1.jpg. I have the large version of the image that resides in www.website.com/images/image1.jpg. Its actual size is 640px by 480. When I mouse over my thumbnail, I don't want the thumbnail to appear for the larger image, I want the large image to appear instead? Let me know if you need ellaboration. Any help would be great! Thank you. Javascript Code: <script language="JavaScript">
function Change_Big_One(thumb){
document.getElementById('BigOne').src=thumb.src.replace("_th","")
}
</script>
HTML THUMBNAIL Code: <div><img src="https://www.website.com/images/thumbs/image1.jpg" class="thumb" onMouseOver="Change_Big_One(this)"></div> HTML LARGER IMAGE Code: <div><img src="" id="BigOne"></div> QUESTION 1: Hello. I would like to know if this is possible with Javascript, and if yes, if someone can please provide me with the code or point me in the right direction. Let me start of by saying that this is for an eBay listing. I know that they accept basic / limited javascript and if what I am asking is possible, I hope that it can work on eBay listings. I would like to know if it's possible to determine the dimensions of an image with Javascript from an Image url, and to then resize it or not based on the the size of the image. So, let's say this is the URL: www.adomainname.com/image.jpg and let's say that image is 1400 px x 1400 px. I would first like the javascript code to detect that size. I also would like the maximum dimension for any side of the image to be 600 px. If both sides of the image are over 600 px, for both sides to be reduced proportionally to 600 px or lower. If any one side of the image is larger than 600 px, the image is to be resized to 600 px or lower. If both sides are under 600 px, the image is to not be reduced. It would also be nice if it can detect whether the image is portion or landscape based on I guess the larger side, because an image at 600 px in height might be too big, but in width might be o.k. So, in this example (the 1400 px by 1400 px), the image is to be resized to 600 px x 600 px. For an image that's 300 px x 500 px, it should remain as such. For an image that's 400 px x 700 px, it should be resized to 400 / (700 / 600) px by 600 px, which is approximately 343 px x 600 px. I have looked a bit into this and I see things being mentioned about the image being loaded first completely on the screen, or about using server side language like PHP, and so on, but like I said, keep in mind that this is for eBay, and so I am limited. Note: The part that I am most interested in is in being able to detect the size / dimensions of the image. QUESTION 2: On a side note, does anyone know if it's possible to have a Javascript enlarging function for images, in which when one clicks on an image, it is enlarged, but either in a popup window that's smaller than the one behind it, and possibly centered, or by making the background go dark and then bringing up the enlarged image (is the latter done with Javascript; I have seen this effect for a while now and have always wondered.) 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. |
