I am developing an online learning system (PHP, MySQL and Javascript). I would like to track what pages and how long each users spent on each page. Ideally, I would like to record this in a MySQL database. My question is 2 fold: 1. What kind of fields would I include in my db table to record multiple pages accessed? 2. Is this problem be...
For a web app I'm making, I'm going to be getting text strings coming in, occasionally which contain quotation marks. Because I am then going to be document.writing the string, they need to be changed either into apostrophes or escaped. How would I do that, because when I try it doesn't seem to work, specifically I think because the st...
Im using a preloader to load large images before I display them.. I am using this script: http://davidwalsh.name/mootools-image-preloading-progress-bar I want to make it disappear when it reaches 100% loaded. I have modified the script by adding progressBar.set(0); to the onComplete function at the bottom of the page. However, now t...
The Prototype event listener I use for changes in select menus is not being triggered in IE. Event.observe('use_billing', 'change', Checkout.getBillingData); This works fine in Firefox (of course), but nothing happens in IE (of course) - I've been Googling this for some time, but I have not found a suitable solution to this problem. I...
This might be a weird question. Anyway, I'm working on a jQuery plugin and this is a useful piece of code for this question, note that it's not all ;) : Javascript: (function($){ $.fn.newPlugin = function(){ var ranges = [], selectableRange = this; function init(){ selectableRange.live('mousedown', func...
I need to capture the keyup event to provide live validation when user is typing in an input (change event fires only when the input loses focus). I am having trouble getting the edited value of the input that fired the evnt. The code also runs on timer to prevent multiple calls when user is typing (fires only every 500 ms). I have se...

We have code such as the following for including it from a file on the web server, but I want to include it from a CDN instead. {javascript file="prototype.js" priority=20} When I access the Smarty documentation at http://www.smarty.net/manual/en/ "javascript" cannot be ...
Ok, this is downright bizarre. I am building a web application that relies on long held HTTP connection using COMET, and using this to stream data from the server to the application. Now, the problem is that this does not seem to go well with some anti-virus programs. We are now on beta, and some users are facing problems with the appl...
My web site uses 16 x 16 pixel icons (stored on the server as png files). I'd like to provide functionality for users of the site to edit these icons. My site already uses jQuery and jQuery UI, and I'm familiar with these, but any suggestions would be welcome. EDIT It seems that this is harder than I thought. I think I'm going to hold ...
Hi Guys, I am trying to use the prototype framework to hide a '< div >' based on a particular URL. I don't have access to server side - so I have no choice but to do this using prototype [restriction of platform using prototype].

I'm developing a site which is growing a bit complex and so I started documenting my code. For PHP I have used PHPDocumentor; in any case it seems that any other tool (such as Doxygen) would accept the same tags. Now I want to document the JS side. I see at least JSDoc and ScriptDoc (and probably others) exist, and they accept differen...
I have this jQuery code that handles hovering over rating stars, when you hover they glow as they're meant to. Problem is, once you've taken your cursor out, it still displays what your cursor was on (and doesn't show the original rating). How can I make it check for when the cursor is removed, then show the original ratings? $(document...

The width of the div is 400px; the image starts moving from right to left, but I can't figure out how to make it start appearing from behind the div border.

Hi Guys, Struggling a little here with prototype = I've created this function Event.observe(window, 'load', function() { if ($$('#test li:first')!=null) { $('test').down('li').down('a').update('Test'); } }); Basically, it works on pages where #test li:first is found but on pages it isn't it returns $("test").down("li") is undef...
I have a div that I want to toggle between displaying or not when a user clicks on a piece of text. I have a javascript function that toggles a div on or off. That works fine. What I don't know how to do is to have a triangle that points to the right or down depending on whether the div is open. My HTML looks like this: <a onclick="tog...
