Is it possible, using client-side JavaScript, to test a series of download sites to see which is most likely to be the fastest file download site for a user?
I wondered whether JavaScript could download a portion of a file, or alternatively a small sample image file, just to test the download speed of each site, then report to the user the fastest, next fastest, and so on.
I'm trying to use cluetip jquery plugin inside a message_container div which will be updated once in a while through ajax. The plugin works just fine in any other div, but it seems that in message_container div the already loaded external javascripts are not present ie the plugin doesn't work. Do you have any ideas what would be a proper solution for this issue?
Is it possible to tell a javascript script to do something else if the page has yet to load completely or the included javascript file has yet to load?
I have an application where the user loads graphics from another site. Presently I advise the user to wait for graphics to load before clicking on adjustments. Ideally, I would prefer a closed-loop approach where code would recognize completion of loading and automatically enable the adjustments.
The pages which have these images are frames.... and even with my best attempts to preload them all still most do not. Some use more than one image and the flicker is obvious.
Below is how I am loading them, and it doesn't matter if I use URL referenced images or locally, (i.e. ./image1.gif)
<script> pic1= new Image; pic1.src="./image1.gif"; pic2= new Image; pic2.src="http://www...."; </script>
Is there a reliable way to pre-load all images in frames, or *should* this work and it's something else?
I have created two pages, the first page is stored in a free public web server, and the second one is stored in a personal computer. This computer is not allways on, so, sometimes, the page could not load.
I want to create a "Zero" page that checks if the second page is accesible (and if it is, then redirect). And if the page is not accesible then redirect to the public server.

I am using a jquery gallery slideshow on my homepage and I am having an issue where the images loaded before the dom is loaded causing the images to display in an ugly stack.
I combated this a bit by setting a height on the div and setting the overflow to hidden. however you can still see the unstyled stack of images within the small div for a couple of seconds before the page is loaded.
I'm having some problem with this DHTML app. The problem is that when i click on an image button, nothing happens. I have verified that the DOM event handlers are loaded. However, when i click on the images (buttons), nothing happens

I am doing an image/data rotating script. I get the data from a XML. I parse that data and build the divs and such.Data Set 1 --- background image in a div, with a button and some text overlayed on the div. ... ... Data Set 4 -- etc..The thing is, I load the script and the div appears, BUT the text overlay appears first THEN the image pops up for the first Data Set. I can't have that. I need them both to appear at once.Is there a way to determine that a div background image is loaded?-- I have access to the prototype js library.
We have to login to a http page so that I can surf the net. But, that login page also requires me to keep that page open which is very irritating. The page have javascript that checks if the page is loaded every 180 seconds, it its not loaded, I am logged out.
I want to simulate a browser using a programming language like python or using curl or anything so that I am not forced to keep the webpage open. How can I do that? I have uploaded the source code of the webpages of login_page, javascript and ajax scripts used.
I am not actually sure as to how it is being accomplished so I dont know how to simulate it. note the sendLiveRequest function in javascipt script.
I saw one page where image was loading. First, there was something like this image (in this text: first image): click. And then, when image (real) loaded, it replace first image.
I need to fire a redirect script after all other scripts on the page have loaded.I've got a redirect page set up specifically to log Google AdWords conversions and Google Website Optimizer conversions. It's basically a few blocks of Javascript, but it loads external JS files from Google's servers and I don't want the JS redirect to fire until after ALL of Google's tracking has registered.
I am trying to call a javascript method on a page that is loaded into a div with ajax.I cannot get javascript functioncalls to work.And I don`t know why,that is when I run the page in its own browser window it works.Can I do it different to ensure it loads javascript?
How do I detect if a couple of images on my page are loaded? I must somehow detect if those images are loaded and if possible, stop the visitor from doing anything until they are loaded.
I have a puzzling message on my page at URL] It says the API is not loaded. The Firebug gives this: uncaught exception: API not loaded, please pass in a 'site' I wonder which API..
I have a textarea on the page. When the page loads, I need it to have some default text (which will be generated dynamically)
so I did something like this
function init() { document.getElementById("TexareaID").value = "default text"; }
window.onload { init(); }
but the problem is firefox always return "TextAreaID" has no properties because the textbox hasn't loaded it yet..it seems. How do I get around that? (I know mabye i can insert the script below the textbox.. but that's ugly. Any other ways?
function checkImage() { var image = document.getElementById("image"); var height = image.height; }
Many times the image height will not be defined.
I recently changed the past so it uses AJAX to change the <img src... stuff to return new data for that inner HTML block..
Still the image will not have properties. Now, this is a problem in IE/FF, but not in opera.
Any ideas on how to make sure the image is loaded so its height/width properties are available... either by swapping the image.src or by using ajax to swap out the div innerHTML??
I am using this to load the client JavaScript for a web application when it is selected by the user) via an Ajax connection to the server.
I have found only two ways of loading new JavaScript after the web page is loaded.
1. Create a new script element (where head is the id of the head tag): var s = document.createElement('script'); s.setAttribute('type','text/javascript'); s.setAttribute('src', 'scripts/myscript.js'); s.setAttribute('defer', false); document.getElementById('head').appendChild(s);
2. eval() of a string sent from the server via XmlHttpRequest.
The first method does not work with Apple Macintosh Safari. There is an article on the apple support website http://lists.apple.com/archives/Web...r/msg00024.html
Does anyone know of any other methods that are cross-browser?
I already know about the IFrame workaround, but I have not been able to determine if that is really portable and practical. Does anybody have experience with this?
I have a device with embedded webserver. Its page offers to reset the device,with the following javascript function:
function Restart() { if (confirm("Your Web browser will lose contact with the camera. Are you sure you want to restart the camera?")) { var form = document.WizardForm form.do_reboot.value = "yes" form.submit() } }
Now I want to execute the reset function automatically on a timeschedule (every 24 hours, from crontab). How do I accomplish this? I guess I need something like the reverse of WGET - something like a WPUT or WSUBMIT, that talks to the embedded web server and submits a form with do_reboot = "yes". However, I have never heard of any such tool.
How can I trigger the functionality in an automated way, without browsing the page and clicking the button manually?
