JQuery :: SOT: Execute JS Before A Specific Image Loads?
May 20, 2009
Can I intercept the loading of an image BEFORE it loads? We're looking at using an img tag for inserting stats on our server. Here's what I'm considering.
1) Collect certain information server side, write an img to the document like so (note the URL vars): <img id="statsImg" src="stats.cfm?somevar=someval" width="1" height="1" />
2) Using JS, intercept the load of this image BEFORE it takes place, and add things to the URL vars. This way, if JS is not present, you get the default stuff, but if JS is present, you get extra stuff.

I have long html/CSS (no CMS or php, etc.) web pages. Some people run away when they see too much content on a page. So I hide the large lower section of the pages and have the user click anchor text to execute simple JS code to change the display from 'none' to 'block' or back to re-hide.
Code:
(BTW my research indicates that search engines do not know the difference between display='none' and normal content, or I would not be hiding content in the first place.)
Within this hidden content, I have anchor text to provide name handles
Code:
So users can click a link and go directly to that section. Within that link I include
Code:
So that works fine within a particular page. But when I want to link to an anchor on another page which is within this hidden content, the browser cannot display the anchor text because it is still hidden.
Is there a way to execute the JS code to change the DOM, changing the display to 'block' on the content of the new page?
I do not see how, because the new page isn't loaded yet, there is no DOM within the browser yet, so how can it be manipulated?
Of course if I was using php I could generate the code with the property set as desired. But for straight up html/CSS/JS pages is this possible?
I get the feeling I am missing something simple here, either a simple solution or the simple fact that this is just an inherent limitation of html.

What I'm trying to do is execute a functions when the body loads. This function will make an XMLHttpRequest and then recals itself every 2 minutes for example. The good thing is it really recals itself every 2 minutes, but it doesn't make any changes. The XMLHttpRequest is a request to an XML file on the internet which changes often, and I want the data of it. When my function recals itself, it displays the data of the first call and never changes after that. So I guess it never makes a new XMLHttpRequest, or it doesn't update the returned data.

In one of my web page I want to show an image preloader. ie When I clicked on the small thumbnail in my web page then the main large image will load. My code looks something like this
$("#images li").click(function(){
var image=this.href;
$("#mainImage").attr('src',image);
});
I want to show the Loading sign until the main image loads completely.

how to make the image a hyperlink to specific urls rather than the image in its own page in the contenflow.js? I've found that if you comment out this line: window.location.href=A You will successfully delete the hyperlinks that link to the full size image. However, I'd like to have a click on each image take you to individual specific pages. PS> I'm a designer not a javascript coder -- so detailed explanations are needed. Documentation: [URL]

Is there something in javascript to make sure that the page is completely loaded and the I execute a function in javascript. Because I have a web page that i have an image slider, so if I open this page in same page before (window.location="source") so the page is loading very fast, but if I use window.open, the page will open in a new window but very slow and the slide show begin but I see that the page is still loading the images, so as result no images is shown. I need to execute the function for the images slider after the page had completely loaded.

I'm having trouble showing a loading image between loads but only in IE.
Code:
function PreLoad(){
cookie = new Image();
cookie.src = "loading.gif";
[Code]....
When a user clicks the button it references ShowImage() - PreLoad is used when the body loads. This works find in Mozilla browsers, but not IE. How can I get the loading graphic to show in IE?
(ShowImage() loads a dynamically generated image, and there is a brief pause before it is show -- that's why I need the loading graphic). I've tried Google but to no avail.

I am working on a demo for a movie site, and 90% of everything seems cool.[url]...
I am doing php.flushes, .htaccess caching and using PNGs to help with performance. I might start using another sub site to grab all the scripting from to increase performance, but it seems a tad bit slow at the moment.
- There are a few issues one being when you click on X-Men and look at the gallery the images seem to flicker sometimes going from image to image.[code]...

I'm trying to add java script to my website so it loads my background image. I followed a tutorial from here, [url] and so I copy and pasted this code into note pad:
And saved the file as imageloader.js. I didn't put the actual website or image in this post because I don't want it to get referenced when searching my website in google. When I open the page, there is no loader, the image takes a couple seconds to load when you first go to my page like usual. Am I doing something wrong? did I call the file a wrong name? should I reference imageloader.js in the html code of the webpage?

<div class="box top"></div>
<div class="box main">
<div class="box header">
<div class="badge"><ul><li class="active"><span>60</span></li></ul></div>
[Code]....
What is happening is $(this) is no longer based on .expand being the (this) that is clicked.
like if i have a button SOMEWHERE randomly on the page with this
<div onclick="Minimize('_alerts');">Click Here</div> this will minimize alerts but because the (this) in minimize function doesn't actually point to the right button that I want to add a class to.
Is there a way to modify the minimize function so that it finds the <div id="mytoggle"><ul> <li class="expand boxminimize" rel="_alerts"> using the rel toggle, and then changes the class of the li from expand boxminimize to boxexpanded??
just like the .expand click function I posted on the top of the post that works?

I've got a rather large image which I need to load into the page and once it's loaded, I want ti fade it in.
I'm using Jquery so I can easily use $(".bigimage").fadeIn("slow"); but how can I make it so it only fades in once the background image of that div is loaded?

I am completely new to Javascript and html... but not to programming.
I'm trying to modify something that someone wrote and trying to keep it standardized... meaning they way the did it. Here is an example of what they did. code...
What I'd like to do is display a png image file in a similar fashion if possible... I'm not sure if it can be done use getElementById.
Actually, I'd like to do <div> instead of a table so that I can layer images. I've converted the table above to using <div>, but again, I can't figure out how to do this with an image file.
The main reason for doing this is because I'd like to use the setTimeout feature.

I need to build a slider. which is not there in the page when it loads. then after few seconds it appears and slides from the right hand side of the window and stops at some position on the screen. then after few seconds it changes its image into another one. each and every one of the images has a different displaying time. that time is a database data and i have to specify it accordingly... I have no idea how to do this and i am a newbie to javascript. i don't know whether javascript can do this, maybe another technology..
