I´m using dreamweaver´s built in preloader for a menu. it looks like this:
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length;
i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
im trying to extend a gallery jQuery plugin and have been succesfull as of now. I extented the gallery as to when i click next it doesnt only show the next image on the gallery, but also changes the src attr on 2 different images with id's "preview1" and "preview2". I am no expert in javascript but im studying software engineering, so im VERY familiar with JAVA(ye i know its different, but thats indicating im no programming nub).
What i want to do is create code that loads the 2 preview images, and then WHEN FULLY LOADED fade them in with the jQuery function.(.fadeIn('slow)What happens now is that images start fading in whilst they havent been fully loaded yet, so you still see the old images ~ half way through the fade. a way i can wait for the image i'm loading for "var preloadimg" to complete, and then continue? I'm puzzled and wasted too many time on this already. What i do not want to do is simply preload all images when loading the site, i only want to preload them when i want to fade them in.
I have tried several preload scripts found here; plus, some of my own. The only thing that works is the unsophisticated loading of those tiny images. The download consist of 100+ images amounting to 50+mb; and, normally completes in less than 1 minute without preload (using DSL).
The preload terminates after 6 or 7 images and seems to time-out in the middle of an image. A reload will download a few more, etc. I have used the <body onLoad=function()> approach as well as the non-function approach of JS that executes immediately with the page's loading. Getting the same results with Netscape-7 and IE-6.
I need to add: The source of the array containing the image references is a '.js' file. That doesn't seem pertinent as some of the images always load.
Has anyone else had this issue? Basically, the preload of images for a rollover effect for the navigation is really really slow when using IE 6.0 but when i view the site using Netscape, it's fast like it should be(no lag!)
My problem is that since 96% of users use IE, i need to figure a way to fix this. Below is the javascript currently being used. The arguments are passed in before the script is called.
function gn_rollover_preload(){ //preloads middle images for the navigation if (document.images){ var argLength = gn_rollover_preload.arguments.length;
for (arg=0; arg < argLength; arg++){ eval(arguments[arg] + "_off = new Image()"); eval(arguments[arg] + "_on = new Image()"); eval(arguments[arg] + "_left = new Image()"); eval(arguments[arg] + "_right = new Image()");
// Now Preload all "corner" images for faster swapping corner1 = new Image(); corner2 = new Image(); corner2_both = new Image(); corner3 = new Image(); corner3_both = new Image(); corner4 = new Image(); corner4_both = new Image(); corner5 = new Image();
Want to know if there is a way to preload a song before the slide show starts. Also, would like to be able to show the lyrics 2 paragraphs at a time, timed with the singer so viewers don't have to scroll to see the lyrics. The lyrics are currently just in a table row with the <td> tag. I would have to have a timer start with the execution of the song, and replace the lyric text as the singer completes each verse.
Or, can you link the photo image with the scroll bar so if they scroll, photo will scroll so they can still see it as they view the lyrics.
I really have little idea of what I am doing, and have gotten to where I am by lifting various scripts off the Internet. Any help would be greatly appreciated. Please keep in mind I am a web designer IDIOT.
im working on a webpage with rollover buttons, and im noticing that on everylink of the page the page reload the buttons again,and again, is there something i can do to use them from cache instead load them every time? it could save time for audience and bandwith for the hosting :) the rollover was made for imageready Code:
I would like to preload all images on a certain page, without 'knowing' which pictures are on the page. (I want to write a .js file, put in the header of all the pages)... So, I don't know what pictures are on the particular pages.
Can this be done? If so, how?
Than another question (if the above is possible)... Say, one of the 'found' pictures can't be loaded (it's not in the correct folder)... can this pictures be replaced with another picture? (for instance: pic_not_found.jpg).
I have attempted to create an external js page that handles preloading and rollovers. The idea is to save some bandwidth by not having this code in the head of every page.
The problem I am encountering is that I have the script doesn't seem to want to work properly through out my file structure which can be seen here.
I got a script that rotates my images, but I have almost 300 in stock and it is preloading all 300 once the script is started. How do I get it to preload one at a time, or nothing at all? Code:
the first 4 tabs are showing some images as background:clicking the tabs will trigger a fading-effect, but as long as the user hasn't watched the 4 images, the effect is "interupted" by the loadingprocess of the images. is it possible to preload those images so that they are in the browsercache or something?
I know that there are scripts on preloading images in order to load page faster.I want something else but for text,in order to load text faster on my page.
default1 = new Image(); default1.src = "images/image1.gif"; changed1 = new Image(); changed1.src = "images/image1-on.gif"; default2 = new Image(); default2.src = "images/image2.gif"; changed2 = new Image(); changed2.src = "images/image2-on.gif";
And this is my rollover code:
var iName=""; function Ichange(p) { var pSrc=eval(p+ ".src"); document[iName].src = pSrc; }
But for some reason on the first mouseover it doesn't seem like the image has been preloaded. There is a delay, like it's looking for the rollover image, which should have already been preloaded. Anyone have any ideas why?
This isn't working and I can't figure out what I'm doing wrong:
var c_imgs = new Array( 'images/champascari.jpg', 'images/champfangio.jpg', 'images/champhawthorn.jpg', 'images/champhill.jpg', 'images/champsurtees.jpg', 'images/champlauda.jpg', 'images/champschumacher.jpg'); var pre_img; for (var i = 0; i < c_imgs.length; i++) { pre_img[i] = new Image(); pre_img[i].src = c_imgs[i]; }
If this code is correct, should I put it in a function and then call for it ?
i am making a gallery and i was advised by philip m to preload my images before hand, so that the gallery runs smooth. i have done so but in a different way to what ive seen on some of the other posts on this forum and i was just wondering if this was practical javascript or am i over doing it.bascially, the images are external hrefs loaded into place holders.the external hrefs are stored as strings in an array.
so the loop runs for however many image hrefs are in the array.so the first iteration of the loop, an image is created and is given the href of whateever value the loop is of the array.then for each iteration of the loop, the var img, is overwritten with the next href in the array.so technically, iam not creating as many images as there are in the array, i am just creating 1 then overwriting it, but still loading the image data in to the browser cache.
I want to use an image as a CSS background-image so I used the Image constructor to load the image: [URL] but I noticed that the browser (Firefox) load the image from the URL and not from the memory when changing the background-image property (it takes about 1.5 seconds before showing the image, and every time I reload the page!)
I have a bunch of menu buttons that rollover properly and javascript preloading that I THOUGHT used to work but isn't now. It's flickering and reloading the images each time the mouse is moved over top and off, even on the same button. I thought they worked perfectly in the past, but with no changes they're not working today. Code:
I have some images 5 or 6 that are 800 x 300 i use in my website banner.The start loading but when number one is 1/3 of the way teh next one starts then the next, it looks real messy nee some way to preload them ... like black square or something .code i used below
<script language="JavaScript"> // configuration structure var A_TPL = {[code].....
I want to create a preload for images but do not want to have to specify every single image file name.Is there a way to just specify a folder and all images in ti will be preloaded?
