JQuery :: Load Image In Background Before Showing?
Mar 1, 2011
I was wondering if anyone knew how to load a image in the background and have the current image show until the new image has been downloaded and then swap out the image.
I currently just have the replace without the buffering. Because of the download time of the new image there is a short time where the image space is blank.
I have 3 background images, and 1 is picked at random to be the background image of the body when loading the page.My code is below. Right now it's just white, can't get any pictures to load. I have checked the URLs and they are correct.
I'm trying to swap the background image of my index page logo div when a document is loaded into an Iframe on the index page. This is what I have so far in the external js of the page loaded to the Iframe. The function is called in the window onload of the same js file but it makes the logo image turn blank. The alert declares 'silver jewelry' and the image I want to replace the logo is named 'silver jewelry.jpg'
Code: var logo=top.document.getElementById('logo'); alert(document.title); function changelogo(){var title=document.title;logo.style.background='url(../sources/'+title+'.jpg)';}
I'm trying to work with a jquery dialog, starting with code from a site at [URL]. I set up a small sample php and modified the code to make an ajax call. It all worked correctly, but when I tried to migrate the code to an existing php page, what happens is the back ground changes to the grayed out color, but the dialog box does not appear. I put alerts in each of the jquery procedures, which all fire, but I can't find the reason why the dialog doesn't show.
The code seemed pretty straight forward, but I was modifying an existing php page I didn't write, so I'm not sure if I'm missing something being new to jquery. Here's the code from an called html file that includes the jquery code followed by the php page code I changed to include the dialog div tag. I removed most of the php code leaving just the final page code that includes the div for the dialog. The css is straight from the sample code in the web page listed above.
<html> <head> <title>Test Page</title> <script src="[uRL]" type="text/javascript"></script> <link rel="stylesheet" href="jdialog.css" type="text/css" media="screen" /> <script type="text/javascript"> $(document).ready(function () { // if user clicked on button, the overlay layer or the dialogbox, close the dialog $('a.btn-ok, #dialog-overlay, #dialog-box').click(function () { $('#dialog-overlay, #dialog-box').hide(); return false; }); .....
I've used the cycle plugin on several Wordpress sites and it works great, except that when I run it the background is visible between transitions. Instead of a smooth fade between images, there is a long pause between images. Even when I use the default values, there is still a noticeable delay between the slides.
I'm having an issue with the status bar in Mozilla and Netscape showing that it is still waiting on the page to load even after it is finished. This problem does NOT occur with IE.
In summary, I am using a onLoad event in the BODY tag to communicate back to another server each time a page finishes loading. I do this by using a "new Image()" and setting the .src property to the server. The .src includes a value in the querystring so I know what request it was that finished loading.
The challenge here is that the status bar still shows "Transferring data from www.mysite.com..." despite the image being loaded. It never clears and leaves the user with the impression that there was a problem loading the page. My web server logs at the mysite.com show that the browser does indeed make a request for the image and I get the querystring just fine and it returns a status of 200 so the image is being found and served ok.
I've tried everything I can think of to solve this and really could use your help please. Bottom line is that if you use the "new Image" statment from within the OnLoad event of the Body tag, Netscape and Mozilla never seem to update the status bar to show "Done" despite it succesfully loading the image.
Here is a simply snippet you can use to easily reproduce this issue:
I am building a simple t-shirt creator app for my shop and I am using the interface.js library: [URL].. docs/drag to drag/drop and re-size the graphic on the shirt background image.
Once the user has chosen a spot to put the graphic, how do I save the background image of the t-shirt with the image they dropped in the correct spot? Like, to merge the two graphics in place?
I am having an issue with setting the background-image of a another div #x to the background image of #y.Correct me if I am wrong but I think you would do this in a simple case by saying
$ ( '#x' ).
[code]....
So when it does it, it is getting the URL of the generator (I logged it. what is actually being passed is [URL] This would require a server call to generate a new image, In this particular application, even if it wasn't exactly the image y had it would be acceptable. But it's not doing it. It is not getting any image at all. Am I doing something wrong, i.e. is it supposed to just work? I would think not, since the page has already been rendered. This is almost an ajax situation but I don't know how to do it for an image. I don't really want to generate a new image anyway, I'd be very happy to get the one that's already there. How would I access the actual image already attached to y and not do another server call?
at [URL] I am using jquery cycle in 5 divs. As you will see, in 4 of them it works perfectly, but in the main image it is only showing every second slide and fading to blank on the others.
Yes, all the images are there.
The weird thing is that I essentially copied and pasted this code for the lower areas and they worked perfectly straight off.
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:[url]....
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.
<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>
I have this working fine, and I can append the preloaded image to a hidden div then fade the div in for a smooth effect.
Problem is I want to set this preloaded image as a css background image, not as a <img /> in a container. But if when the image is loaded, instead of .prepend() I do .css() and set the css property of a background-image to be the preloaded images URL, then when it carries on with displaying it the browser loads the image again. Rather than using the preloaded one.
I want the image to be a background image as I want it centered in the page background, even if it is too large for the viewport.
I have a LARGE, hi-resolution image that I am trying to use as the background for a page. Because it is so large, it takes a while to download. Because of this, I wanted to load the image behind-the-scenes and show it once it is downloaded.
To accomplish this, I'm using the following JQuery code:
This code clearly downloads an image and appends it to my DIV element. However, I really want to set this downloaded image to the background-image CSS property of my DIV. The reason why is because I have content inside the DIV that should serve as the foreground.
How do I dynamically download an image, fade it in, and use it as a background?
This is something of a continuation from my previous problem[URL]The images seem to be showing properly the first time. Unfortunately, when the slide show starts, Chrome is showing the last image in the group first. This wouldn't be a problem normally, but I plan in showing the images in an order based on their last modified info.
I have a problem with internet explorer to show images. Please take a look at: [URL] and click into any image. Using FF, chrome and safari clicking an image show a big centered image with position fixed. Using internet explorer is a full wrong.
What i want is, to show a pop up or a simple div or a modal or any dialogue box to to load on my home page to show welcome message, whats new etc stuff, which will be displayed only once in a day to every visitor of my site,(at the first visit of the day only ) But i want to load this modal after a sec when all the other elements of the pages have been finished loading.
Any way to create a presentation on a website WITHOUT showing load bars? Background info: it is about photography website where someone after seeing full size picture could click to view it in a room setting. Right now my developer created a presentation where full size picture zooms out then there is a load bar (hideous) and then the presentation starts. So it looks like it is 2 different parts and I would like to make it into one smooth presentation. Btw: would like if possible avoid flash animation due to recent developments on Apple's side.
only first image in the all_images array loads and the rest stays hidden. it works first time i load the page, but any other time it loads only one image. i understand it might have to do with the cache. what could be possible cause for breaking the .each() loop after first iteration? i'm using jquery 1.3.2, png fix and php
What is the best way to get the background image url in css? i have found this in crossfade plugin but does not work in opera.. var target = $$.css('backgroundImage').replace(/^url|[()]/g, '');
I am trying to recreate this functionality on my website where you can drag a background image around and when you get ot the edges of the image it bounces back to the edge of that corrosponding side. have a look at the site in question - [url]
So far i have recreated the top left and right edges using
