JavaScript - Image Changer
I may be too close to this to see the answer but i have an image viewer with one big image and lots of little ones. What i need is that when you click on one of the smaller ones it grabs it's image src and sets the larger photo to that src. The small images are dynamic but the larger image will have a static id.
Similar TutorialsHi there. I'm relatively new to coding in javascript, so I'm hoping that some kind souls could help me out! I'm trying to make an animated image height changer (example: changing an image's height from 50px to 500px). I'm working on a new web site using HTML5 and want to add some Flash-like animation to my page using javascript and <canvas>. The animation would only need to "play" one time once the web page has loaded. No looping is required and no user interaction (ie mouseovers, etc) is needed. Any help would be greatly appreciated. If anyone knows of similar examples online please send me a link. If you're interested in helping, please let me know if more information is needed. Thanks.

Plz help me. Thnx in advance Hi, on my site, I have added Style 1 and Style 2 in my menu at the top right http://www.thisisworthing.com/default.php# when I click on Theme 2, it doesn't work?! please help! I have this working on my other site: http://www.mypubspace.com what am i doing wrong?! Hi, I am no very little when it comes to Javascript but I have seen a few sites using pre populated text boxes for login forms. So Username and password appears in the boxes to save space. The code below works fine onload of the site in all browsers, everything also works fine in firefox but ie the following doesn't seem to work. When a user clicks to enter their password in i.e. it doesn't change the form to password characters so input plain text. Also when you click out of either box it doesn't seem to re-populate the boxes with my Username or Password text. Any help would greatly be appreciated. Code: <script>
function HideLabel(txtField){
if(txtField.name=='myusername'){
if(txtField.value==txtField.defaultValue)
txtField.value = '';
else
txtField.select();
} else if(txtField.name=='mypassword'){
if(txtField.value==txtField.defaultValue){
txtField.value = '';
txtField.type = 'password';
}
else{
txtField.type = 'password';
txtField.select();
}
}
}
function ShowLabel(txtField){
if(txtField.name=='myusername'){
if(txtField.value.trim()=='')
txtField.value = txtField.defaultValue;
}else if(txtField.name=='mypassword'){

Hi. I have a JavaScript that resizes an image held within an Iframe. It works perfectly, BUT only works if there is an alert box in the code. /*Image resizing scripts - Dependant on page size!*/ /////////////////////////////////// function Im_Resize() { var imheight = 550; /*Change the IFrame CSS*/ iframeheight = imheight + 15; /* +15px for the x-axis scroll bar*/ var IFrame = document.getElementById('MainFrame'); IFrame.style.height = iframeheight + 'px'; alert('after iframe size - before im change'); /*Change the Image CSS*/ var innerdoc = IFrame.contentDocument || IFrame.contentWindow.document; Image1 = innerdoc.getElementById('MainImg1'); Image1.style.height = imheight + 'px'; } If I take the alert box out the code just doesn't work?? I thought that it was that during the loading of the page an element hadn't been loaded yet, but a delay doesn't work either. If I press 'ok' on the alert box too quick it doesn't work either. In terms of HTML this script is run whenever the page is loaded and is also fired when a click event is detected on one of the divs on the page. Any help would be great Ed Can someone tell me why this short script won't work? <script type="text/JavaScript"> <!-- function timedRefresh(timeoutPeriod) { var number = rand(7); if (number == 1) { var bgcss = "theme1.css"; } else if (number == 2) { var bgcss = "theme2.css"; } else if (number == 3) { var bgcss = "theme3.css"; } else if (number == 4) { var bgcss = "theme4.css"; } else if (number == 5) { var bgcss = "theme5.css"; } else if (number == 6) { var bgcss = "theme6.css"; } else if (number == 7) { var bgcss = "theme7.css"; } document.write('<link href="bgcss "'+ 'type=text/css rel=stylesheet>'); } // --> </script> </head> <body onload="JavaScript:timedRefresh(10000);"> hey guys i downloaded the 'Content Slider v2.4', and this has a feature which will save a cookie used to remember and recall the last content viewed by the user when they return to the page.

//** June 12th, 08'- Script updated to v 2.3, which adds the following features:
//1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.
//2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).
//3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.
//** July 11th, 08'- Script updated to v 2.4:
//1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")
//2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.

as far as i can see, the parts of the code which are about the cookies are labeled "enablepersist" thanks guys Hey, I'm working on a script that uses a function (called on click) to change the content of a div (called description) within the page. It contains an unordered list and list items. The first one has the class "show" and the ID "1", the second with just the ID "2", and so forth. (see code below). I am using jQuery to control the onclick function. the jQuery gets the current object with the "show" class. If there is no show class, it takes the first. It then puts a variable string together that represents the UL LI that is needed to be shown. Code: var descurrent = ($('div#description ul li.show')? $('div#description ul li.show') : $('div#description ul li:first'));
var desclass = '#description li#'+x;
Note: x is a variable transfered from the function change(x); where x is the ID that is to be shown HTML CODE: Code: <div id="description"> <ul> <li class="show" id="1">blahblah </li> <li id="2"> etc </li> </ul> The jQuery i'm trying to get to work is: Code: //Hide the current image
descurrent.animate({opacity: 0.0}, 1000)
.removeClass('show');
//Show new image
$(desclass).addClass('show')
.animate({opacity: 1.0}, 1000);
Note: the class "show" has a higer z-index Thanks in advance, Hope this can be resolved soon, been giving me headaches! Cheers, John 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">

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. 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, My site has an image gallery with a row of pictures at the bottom. When I load up the page it should show image 1 in the main gallery window, but instead it's showing image in position #10 (the one to the left of #1). You can see what I'm talking about here. When you load the page it's showing the White House, but it should be showing the Green House (position #1 in slider). The White House can't be seen in the slider since it's in position #10, but shows up first int the main window. Is this a javascript issue or what? All JS files can be found here Can anybody help me debug this?? I'm going nuts Thank you Hi, So here is my problem. I have a main image that has a bunch of images (e.g., stars) on top. I place the stars in absolute positions on top of the main image. If a user resizes the brower, then the position of the main image changes, so then the stars are off position (not on top of the main image). Should I: 1) make the main image be in an absolute position? or 2) do something else such that the main image moves around if the browser is resized? but then I don't know how to re-adjust the positions of the stars on the fly. Hi, I am still designing the website and want some flexibility. I am capturing the mouse clicks fine on top of an image, but the coordinates are absolute and not relative to the image. How can I capture mouse clicks relative to the image so that I can move the image anywhere in my website? Thanks! Here's what I usually use and have been using for years and it works great, just not for this particular purpose. I don't have a clue when it comes to javascript. Code: <noscript><img src="no_script_quote.gif" width="406" height="94"/></noscript><script language="javascript">

images[4]="quote5.gif"
var preload=new Array()
for (n=0;n<images.length;n++)
{
preload[n]=new Image()
preload[n].src=images[n]
}
document.write('<img name="defaultimage" src="'+images[Math.floor(Math.random()*(images.length))]+'">')
function rotateimage()
{
if (curindex==(tempindex=Math.floor(Math.random()*(images.length)))){
curindex=curindex==0? 1 : curindex-1
}
else
curindex=tempindex
document.images.defaultimage.src=images[curindex]
}
setInterval("rotateimage()",delay)
</script>
But, now I want to be able to set a default picture to be shown first and have the random pics appear next. I also don't want the default pic to show up again in the random array. So basically, every time the page was first visited, or refreshed it would show the default picture then move into the random pics. Is there anyway to modify the code that I'm using to accomplish this? Or... Any help would be appreciated. Thanks, Dell Hey folks.. Hope you can help, I'm completely new to this and have no knowledge at all when it comes to javascript. Have been using this script on my site for a while. Is there anyway I can add a URL link to the images that are in my selector? When clicked would go to that page on my website.

The HTML where it is displayed: Code: <img id="mainImg" src="images/gallery/1.jpg" style=" border: solid #7d3d3d 5px;" alt="galleryimage" /> I came across your forums here and it looked like a great place to get some help, and help is exactly what I need! I have been struggling with this javascript that changes an image and its corresponding useMap. For reference: - All images are the same size and located in the same directory, except the main map image - All images are preloaded (I did this just in case it was an image problem) - The page works fine in Firefox, and fine in IE until it crashes - http://www.forthecode.com/imagemap/untitled.htm The Problem: - When clicking on a state in the main image, the state image appears, if you then click on the "return to the overview" it returns to the overview image then promptly crashes IE within 1-2 seconds. - This even happens in a completely blank page (no other content) Exceptions: - Clicking on the state Mississippi does not cause this problem (you can go back and forth with Mississippi without problem) - Tennessee, Ohio, Arkansas, Illonois crash as soon as their state map comes up! The Javascript function itself: Code: <script language="Javascript">
function changemap(vari){
var vari;
var stoptime;
if(vari=="regionview"){
document.regionmap.src = "/images/branchmap2.jpg";
stoptime = setTimeout( function changemap1(){ document.regionmap.useMap="#Map"; clearTimeout(stoptime);} , 300);
}
else{
document.regionmap.src = "/images/states/" + vari + ".jpg";
stoptime = setTimeout( function changemap2(){ document.regionmap.useMap="#"+vari; clearTimeout(stoptime);} , 300);
}
}
</script>
The image tag and image maps: Code: <img src="images/branchmap2.jpg" name="regionmap" usemap="#Map" border="0">

This is exactly how it is in my html files. I really appreciate any input, suggestions or comments you can give me. Thanks in advance! Hi there, I found this thread on the forum its from a few years back but the code works, but I can't seem to get the image that appears as you rollover the button to display in the correct place. I'm not sure if its because I'm using tables within tables? Should I recode in divs? Any help is greatly appreciated!! http://www.codingforums.com/archive/...p/t-95847.html |
