JavaScript - Javascript Image Gallery Internet Explorer Issues
Hi,
I'm fairly new to javascript, I created a javascript image gallery using a tutorial found on web monkey. Please see below: Code: <script language="JavaScript" type="text/javascript">
<!--
var interval = 1500;
var random_display = 0;
var image_dir = "images/exhibition/"
var ImageNum = 0;
imageArray = new Array();
imageArray[ImageNum++] = new imageItem(image_dir + "exhibition-sealskinz.png");
imageArray[ImageNum++] = new imageItem(image_dir + "exhibition-orchard.png");
var number_of_image = imageArray.length;
function imageItem(image_location) {
this.image_item = new Image();
this.image_item.src = image_location;
}
function get_ImageItemLocation(imageObj) {
return(imageObj.image_item.src)
}
function randNum(x, y) {
var range = y - x + 1;
return Math.floor(Math.random() * range) + x;
}
function getNextImage() {
if (random_display) {
ImageNum = randNum(0, number_of_image-1);
}
else {
ImageNum = (ImageNum+1) % number_of_image;
}
var new_image = get_ImageItemLocation(imageArray[ImageNum]);
return(new_image);
}
function getPrevImage() {
ImageNum = (ImageNum-1) % number_of_image;
var new_image = get_ImageItemLocation(imageArray[ImageNum]);
return(new_image);
}
function prevImage(place) {
var new_image = getPrevImage();
document[place].src = new_image;
}
function rotateImage(place) {
var new_image = getNextImage();
document[place].src = new_image;
var recur_call = "rotateImage('"+place+"')";
timerID = setTimeout(recur_call, interval);
}
// -->
</script>
However unfortunately there are two issues, one is IE6 is coming up with javascript errors and IE7 gets an error when you click the previous button on the first image. The buttons look like this: Code: <div id="left-arrow-container"><a href="#" onClick="prevImage('rImage'); clearTimeout(timerID)"><img src="images/left-arrow.png" alt="left arrow" name="leftarrow" width="58" height="37" border="0" id="leftarrow" /></a></div>
<div id="see-the-whole-project"> see the whole project</div>
<div id="right-arrow-container"><a href="#" onClick="rotateImage('rImage'); clearTimeout(timerID)"><img src="images/right-arrow.png" alt="right arrow" name="rightarrow" width="58" height="36" border="0" id="rightarrow" /></a></div>
Being new to javascript I don't know how to get round these issues so if anyone could advise me I would really appreciate it. Thanks Gary Similar TutorialsHello, I have been trying to trouble shoot this for quite a while and am stuck. My site works 100% on Firefox, Safari, and Chrome, but in Internet Explore (6,7,8) the only thing that shows up is the background image. The site utilizes a few scripts: MooTools, a rollover replacement script, an iframe custom scrollbar script, and the Zenphoto CMS, that is utilized on other pages and displayed in the iframes. I think my problem may be mootools related, bur really have no idea. This is the site: http://www.ErikaCervantes.com Here is the offending code: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

Thank you very much! Hey guys, I am having a bit of a hassle getting IE8 and 9 to deal with a rollover properly. On this page: http://www.robleydesign.com/works/ If you rollover any of the projects a View Project button comes up. In Firefox, Safari, Chrome ect.. the area for the hit box on that link is large and easy to click. For some reason in Internet Explorer it becomes a huge frustration clicking the button. I can't figure out why its not treating the whole button as a block element. I've got a flash music player (audioplay) on a site (yeah, I know, I hate music on websites too, but the client wants it). I'm using javascript to trigger "stop" and "play" and it works on every browser except IE 9+. The error in IE's developer says: SCRIPT438: Object doesn't support property or method 'stopMusic' Here's the javascript: Code: <script language="JavaScript" type="text/javascript">
function getPlayer(movieName)
{
if (navigator.appName.indexOf("Microsoft") != -1)
{
return window[movieName];
}
else
{
return document[movieName];
}
}
function play2()
{
getPlayer('player2').playMusic();
}
function stop2()
{
getPlayer('player2').stopMusic();
}
</script>
Here's the working example: EXAMPLE when this page is viewed in IE (8), IE tells me there's an error on the page. Quote: Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Win64; x64; Trident/4.0) Timestamp: Tue, 17 May 2011 14:29:31 UTC Message: Invalid argument. Line: 7 Char: 17603 Code: 0 URI: http://cpanel4.frontline.net/~ggarch...cufon/cufon.js Here's what that Javascript file looks like: http://pastebin.com/T2vgugm2 I honestly know very little about Javascript. I installed a wordpress theme that already contained this bit of Javascript so please be patient with me on this one. please advise. thanks in advance! Hello, im new and hope you can help me out. I am running some javascript on my vbulletin forum. One is for some ad network to display ads, I noticed this working in firefox and chrome but not IE. After some investigation I realised my analytics javascript snippet is conflicting, if i remove the javascript for my analytics then the ads show in all web browsers. The two pieces of code a Analytics; Code: <script src="/mint/?js" type="text/javascript"></script> Ad network; Code: <script type="text/javascript"> var EB_campid='5336510241'; </script> <script src="http://www.zintext.com/showads.js" type="text/javascript"></script> Any help appreciated. Dave. Hey everyone, this problem has been bothering me for awhile, so I decided to finally stop banging my head against a wall over it and seek out some help. I'm fairly new to web development, but through W3Schools and the almighty Google, I managed to make my way through developing a site for the company that I intern for. The site is designed to query a Microsoft Access database and display the results, so employees can see the results of tests run on another machine in a different area. I did not design the database or queries for this project, but assume that they function as they are supposed to. The way the website works is by displaying a form to the user with a number of check boxes (it varies by page) that each add another parameter to the query. When the query button is clicked, I used the "onclick" action of an HTML button to send the form data to a JavaScript function to be processed. The JavaScript function filters out what I need to send to a php page that runs the query. I send the information from the JavaScript function using an XMLHttpRequest, and replace a line of text in the HTML document with the returned results from the php script. I have tested the completed website in several browsers. It works flawlessly in Chrome, Firefox, and IE9. The problem is, it doesn't work with IE7 or IE8, and even though the company I work for is making a widespread upgrade to Windows 7 from XP within the year, they don't plan on moving beyond IE8. When I load the page in IE8 (I'm running WAMP as my server), I can see that my php scripts work just fine, because some of the fields used to configure the query are generated using php, and they appear as they should. However, when I click the form button that triggers the JavaScript function, nothing happens (IE7 and 8 both report "Error on Page"). I've gone through nearly every Internet Options settings, as far as I know, and I'm fairly certain that every setting related to scripting is enabled, though I've only tried testing the site on IE7 and 8 at work and not at home (where I have unlimited security access). Below is the HTML for the button that triggers the JavaScript function, "displayTable": Code: <input type="button" name="button" value="Show Results" onclick="displayTable(this.form)" /> I'm not sure how easily this problem can be fixed, so if anyone needs to see any other bits of code, I can provide those. But my main question is, does this sound like just some setting in IE7/8 that I don't know about (keeping in mind that, with all the settings the same, the site works fine in IE9), or does IE7/8 simply have some inherent flaw in interpreting JavaScript, and will it be necessary for me to rewrite my code taking some other approach, and if so, what language would be recommended in place of JavaScript in IE7/8? Thanks! hi everyone, I hope you can help me understand why my Javascript menu is different on Chrome browser. It is fine on Internet Explorer. Please see images. Internet Explorer Google Chrome I look forward to hearing from you. Ravi Hello, I'm new to Javascript programming. I have designed a Javascript to carry information from one page to another. It works fine in firefox but does not work in internet explorer. Is there some coding that needs to be specified for my script to work in ie? Thanks The problem stems from Internet Explorer's inability to expand questions in the FAQ section of my website ( link: http://phonesforyourcharity.com/faq.php ). Of course the expand function works in Firefox and Safari. The <script type="text/javascript" src="js/faq.js"></script> in the source refers to: PHP Code: $(function(){ $("dd.answer") .hide(); $("dl.faq dt") .append("<br /><a href='#' title='Reveal Answer' class='answer-tab'>Answer</a>"); $(".answer-tab") .click(function(){ $(this) .parent().parent() .find("dd.answer") .slideToggle(); return false; }); }); Hi All, This is my first post in this forum. I am relatively new to javascript. Hope I get some guidance here. Also I would like to contribute here when I get little expertise on javascript. I have developed following snippet of code, which is working very well with firefox 6.0. But when it comes to IE 8.0, it just does not work. Quote: <SCRIPT LANGUAGE="JavaScript"> function refreshFrame() { frames['top'].window.location.href = "report.php?parent_id=<? echo $parent_id; ?>"; } </script> </head> <? include('style.php'); include('PHP_functions.php'); print(" <FRAMESET rows='96,100' onLoad=refreshFrame() BORDERCOLOR=blue BORDER=0> <FRAME SRC=blank.html SCROLLING=NO NORESIZE NAME=top> <FRAME SRC=manage.php?view=show_all&parent_id=$parent_id NAME=bottom> </FRAMESET> "); ?> </HTML> In the above script, I am trying to load the frame top after loading frame bottom, as the latter takes more time to load due to some processing involved. Till frame bottom is under processing stage, I display a message "Processing Please wait" which is coming from blank.html. Working under Firefox: It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on first half of the web page. This is the expected result. Here URL does not change as the URL remains same as before "http://xyz.com/index.html" Not Working under IE It loads blank.html first and displays the message as "processing please wait". Once frame bottom has completed the processing it displays its contents at second half of the webpage. Then finally frame top gets loaded on whole page instead of first half of the page. Here URL changes to complete new URL as "http://xyz.com/report.php?parent_id" Can anyone please suggest what could be reason for this. Thanks, Vinay Hello everyone, I have a very strange situation here where Internet Explorer popup a new window on only one of my <a> elements. I created multiple <a> elements that do the following: Code: <a href = "javascript:popup('overview1.php?pID=<?php echo $pID;?>')">
<button class = "button" type="button">Overview </button></a>
<a href = "javascript:popup('overview1.php?aID=<?php echo $FinalID[$key];?>')" style="float:right;">
<button type="button"><img src="image/Details.PNG" height="20px" width="20px"> </button></a>
<a href="javascript:popup('cart.php?aID=<?php echo ... ?>)</button></a>
<a href="javascript:popup('addnew.php')">
<button class = "NavButton" type="button">Add New</button></a>
Out of the four buttons/link, only the first one is working properly (Open a new popup window) Below is my simple javascript code to open a window. Code: function popup(url){
cuteLittleWindow = window.open(url, "littleWindow", "location=no,width=1020,height=650");;
cuteLittleWindow.focus();
}
I have no idea why ie is acting like this and all the other major browsers work just fine with my code. Please let me know what you think is the issue and I greatly appreciate your help.

So I think ie doesn't even call the javascript function onclick. If the first one works this is not the case. Are you sure that the PHP is inserting correct information? Did you check for errors after the click has been done or just when the page is loaded? Do you have a live version to see?

It never triggers an event and so regular JavaScript event processing doesn't work. In this instance the browser's popup blocker is expecting the request to open a new window to originate with a user event and so blocks the request because there is no event. Instead of: Code: <a href = "javascript:popup('overview1.php?pID=<?php echo $pID;?>')">
<button class = "button" type="button">Overview </button></a>
use the following in the HTML Code: <button id="overview1" class="button" type="button">Overview</button> and in a <script> tag attached just before the </body> tag insert the following line of code: Code: document.getElementsById('overview1').onclick = function() {popup('overview1.php?pID=<php echo $pID;?>');
Repeat the change for the other buttons (you only need the one script tag wrapped around all the JavaScript). i'm having a problem getting something called JavaScript Bitcoin Miner working in IE6+ the error i'm getting is: Line: 8 Char: 6 Error: 'JSON' is undefined Code: 0 URL: http://192.168.0.105/Bitcoin_Miner/index.html does anyone know how i can get this working? thanks. Attached is the source files. BTW... you'll need to instal XAMPP to get this working correctly on your local PC. But if there's a way all of the PHP can be converted to PHP, and Jquery can be cut out of the picture, it would be VERY helpful It works in Google Chrome but not Firefox and Internet Explorer. My computer has blocked Opera and I don't know how to change that. Too much energy to investigate now, I'll do so later. Are there any pros that can tell me why this is happening? I'm assuming GoogleChrome is fixing a syntax error that FF and IE don't. Code: var request;
request=false;
try {
request = new XMLHttpRequest();
} catch (trymicrosoft) {
try {
request = new ActiveXObject("Msxml2.XMLHTTP");
} catch (othermicrosoft) {
try {
request = new ActiveXObject("Microsoft.XMLHTTP");
} catch (failed) {
request = false;
}
}
}
function isAlNum(str){
return /^[a-z0-9]+$/i.test(str);
}
var preUsername;
var same;
function updatePage() {
if (username.value.length>0){
if ( request.responseText.indexOf("0") == -1 )
{userNameErrorBox.innerHTML=username.value + " has already been taken";
usernameSuccessBox.innerHTML="";}
else
{userNameErrorBox.innerHTML="";
usernameSuccessBox.innerHTML=username.value + " is available";}}
}
function nameTest()
{
if (username.value==preUsername)
{same=1;}
else
{same=0;}
if (!isAlNum(username.value))
{if (username.value.length>0)
{username.value=preUsername;}}
else
{preUsername=username.value;}
if (username.value.length>0 && username.focus && same===0)
{
userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";
request.abort();
var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
}
if (username.value.length===0)
{ userNameErrorBox.innerHTML="";usernameSuccessBox.innerHTML="";preUsername=""; }
}
I back tracked what i did and it appears that this code Code: var url = "/unseen/checkIfUserNameExist.php?name=" + username.value;
request.open("GET", url, true);
request.onreadystatechange = updatePage;
request.send(null);
has the problem. When I set up alerts to see what works and what doesn't, this code seems to be causing the FF and IE to not work, but I can't tell what it is that's causing them to fail. This is javascript that is suppose to check if a name has been taken by another user. I'm working on a fairly large project that I wish to be the new formspring, (size wise) I procrastinated for 2 weeks of my 12 week break and now that I'm just getting started on it I'm running into an ishness load of problems... Very de-motivating I hired psd2html.com to code my portfolio website because I had no idea where to start. They designed a specific gallery for me and I don't like it anymore, and it's the last thing holding my back from making my portfolio live. Here is what it looks like right now: http://www.mustlovepink.com/index2.html I attached an image that describes what I would like the gallery to look like. I don't think it's all that different, but the code is honestly such a mess that I need someone to help me with it. I don't even know where to begin If you need more information in order to tell me, feel free to let me know. I really want to get this thing figured out. Hello there, I am trying to incorporate Lightbox2's image gallery script into my site but I'm having difficulty. Here's where I'm accessing the script from: http://www.huddletogether.com/projects/lightbox2/ Here is my skeleton website: http://www.labellepetraie.com/photos The image thumbs are showing up but the larger images are not. I changed the 'body onload' html tag to window.onload as I'm using two different javascripts on this page and I don't want them to conflict. I've also added initLightbox() so I don't know what's wrong! Is there just an issue with the images or is there something wrong with the script. Please help! Let me know if you need additional info. A million thanks! <script type="text/javascript"> window.onload = function(){ // use this instead of <body onload …> MM_preloadImages(MM_preloadImages('../3websites/home4.jpg','../3websites/amenities1.jpg','../3websites/inquiry1.jpg','../3websites/rates1.jpg','../3websites/photos1.jpg'); initLightbox()") } </script> 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. 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 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. Hi I am using the css image gallery I got from: http://www.dynamicdrive.com/style/cs...image-gallery/ I want to change the behaviour, currently an image is enlarged when a user hovers over the link/thumbail. I would like to change it so that the main image is instead shown onclick of the thumbnail, and remains enlarged until another click. Is this possible using some javascript? |
