Any Way To Compute How Much Data Downloaded?
Mar 23, 2009I am working on implementing a carousel-style switcher (using a pre-built script dependent on the MooTools library) on the home page of one of my Web sites. The script displays a series of thumbnail images. When the user clicks on one of those thumbnails, an AJAX request returns the following items, which are then switched out using javascript:A background image (usually between 50 and 100 kilobytes)A foreground image (usually between 10 and 20 kilobytes)A header for the promotional item (strictly text)The body text of the promotional item (text and HTML code, generally no more than 200 characters of text)I have all of that working properly.
When the user clicks on the thumbnail, the AJAX function executes. Then, I use javascript to invoke a new Image() object to load the background image. Once that's completed, I invoke another Image() object to load the foreground image. Once both requests are fully loaded, I switch out the information. While they are working, I display an animated gif that indicates the information is loading. However, if at all possible, I would like to implement a progress indicator rather than just a simple animated gif. Because of the size of the background images, it can sometimes take between 10 and 15 seconds to load on a dial-up connection (even longer if the user's connection is especially slow or overloaded).
That's a long time to sit and stare at a "loading" image, especially if there's no way to indicate whether it's going to actually do anything or if it's just completely stalled. I am already sending the filesize of the background image and the foreground image to my javascript using the AJAX request, so if I need to use that somewhere in my script, I can easily do that. However, I've hit a roadblock in trying to figure out if there's a way to determine how much the user has actually downloaded successfully. From most of my research, it does not seem possible (due to security issues) to determine any sort of file size on the user's local computer using javascript.
However, the majority of the information I've found on the subject seems to relate to the opposite type of situation (users uploading files rather than downloading). The few examples I've been able to find for "download indicators" seem to simply count the total number of images being loaded, then divide 100 by that count. Then, for each image that loads, it adds that percentage to the indicator. Since I will always be loading two images, that means that my download indicator would always display 0%, 50% or 100%, which isn't much more helpful than the animated "loading" gif I'm already using. Is there any way to use javascript to determine how much (percentage-wise or in bytes) of a file a user has downloaded from the server into their cache?
What Is The Algorithm To Compute The Factorisation Of An Integer?
Oct 30, 2006I need some ideas on how to compute the factorisation of a non-zero integer?
For example:
if the user input is 8, its factorisation is 1 * 2 * 2 * 2;
if the user input is -300, its factorisation is -1 * 2 * 2 * 3 * 5 * 5
Does anyone know?
JQuery :: Compute Body Width WITHOUT Scrollbars?
Jun 15, 2009I have an application that resizes itself upon window resize. Theproblem is that if I resize down the window so it is smaller, twoscrollbars appear during resize (nothing new for now...), but thecomputed body width is the width with the scrollbars.Then, when I stop resizing, my app resizes itself, but as you may haveguessed, there are a small empty space on right and bottom,corresponding to the scrollbars.I have not found a pretty way to do it (of course I could set a timerinside my resize function that will call itself again 10ms later, just

Call The Click Event Of The Link (anchor Tag) On The Click Of The Button?
Jan 24, 2011I want to call the click event of the link (anchor tag) on the click of the button. I used this code below in the click event of button to call links click event and it works fine in IE.
document.getElementById('linktag').click();
But, this doesn't work in Firefox. I googled a bit and found that in firefox, you have to do something more to achieve this behaviour. So, I ended up doing this on button click to work in firefox:
var link=document.getElementById('linktag');
var e = document.createEvent('MouseEvents');
e.initEvent(

The above code does the click on link when I click on the button. But my problem now is that I have defined a link as
<a href="mailto:abc@xyz.com?subject=abc&body=email body">email </a>
and when click is called and mailto links opens my email client, it somehow ignores the subject and body parameters of the link. It works properly when i actually click a link element. but it doesn't work when i simulate the click event by code written above. above dispatching event code somehow ignores the link parameters?
JQuery :: Dynamically Add Radio Button - Handler To My Form On A Button Click ?
Jul 13, 2010I am trying to produce a web form to allow wedding guests to RSVP. The form allows them to enter a name and select from a radio button whether they will be attending or not. If they select the "yes" radio button then a further pair of radio buttons are displayed for their meal preference.
They can then click a submit button or they can click another button to add another line for another guest which operates in exactly the same way. I've almost got this working, but it seems that the checkbox change handler is lost for the current guest when a new guest is added and the checkbox value is reset. I've got a feeling I'm doing something stupid but can't for the life of me figure out what.
Code (source file (renamed to .txt) also attached as I'm not sure the pasted code is too clear):
Why Does It Sometimes Display 'undefined' - When Click On Button - Random String From RandomString Variable Appears Below Button
Nov 16, 2011What happens is that when I click on a button, a random string from the RandomString variable appears below the button. e.g I click on the button and it displays 'AAB' and then if I click on the button again it may display 'AAE' and etc.
The problem is that sometimes it displays 'undefined'. I don't wanit 'undefined' to appear but why does it sometimes display 'undefined' rather than a Random string.

Jul 20, 2005In some pages of my website I use a code like the following:
for (var n = 0; n < getTagsArray("SPAN").length; n++){
//SPAN is just an example. I also use other tags
tag = getTagsArray("SPAN")[n];
//make something with tag...
}
function getTagsArray(Tag){
if(document.all){ //Internet Explorer
return document.all.tags(Tag);
}
else if (document.layers){ //Netscape
eval("return document.tags." + Tag);
}}
I want to put all browser-specific code inside the getTagsArray
function. So far, I've programmed only for Internet Explorer (my
browser), but now I want to make my website visible to all browsers.
I'm not sure about the getTagsArray function. Is it right or is there
a better way to do the same thing? And how can I extend that function
to make it work in other browsers?
Finally, where can I find some information about cross-browser
programming? I have the javascript reference for Internet Explorer and
Netscape, but I know nothing about other browsers.
