Is there a best practice for making tooltip type functionality accessible to people with accessibility needs? I am interested in jquery tooltip and have found a few others but I am thinking twice before spending anytime as I am concerned about accessibility compliance of these. ...
Hi, I'd like to know what are the steps required to create a framework on top of node.js. I believe this can be a good way to learn, that's why I'm doing this! I've been checking other micro-frameworks and bigger frameworks but I'm not being able to understand where to start. I'd like your advice on this. Thank you. Edit: MVC Framewor...

I am in the process of selling the facility to a client 'on licence' But he wants the code/script on his server.

I know that in JavaScript you can add new properties to an existing type (like Date), but is it possible to add new properties to an anonymous type after it's been defined? For example, say I have the following script: var employee = { 'Name': 'Scott', 'Age': 32, 'JavaScriptNewbie': true }; Later on in my script I want to...
Hey guys, For some reason, I can't change the contents of a DIV in either IE or Firefox. Any ideas where I might be going wrong?

When you wrap your JavaScript in a function like this: (function(){ var field = ...; function doSomthing(){... ... })(); I noticed that this fixes scoping problems for me on a lot of web pages, but I've never actually known what this practice is called. ...
Often a user will misuse a Rich Internet Application, and attempt to use the browser's Back Button. Such mistakes can be disruptive to changed but unsaved information, as in a Flash or Flex application. It is a simple matter to alert the user for confirmation before leaving the page (see below). However, I have a client who strongly...

Hi, I'm getting a weird behaviour with javascript which I fail to understand: my application's javascript relative URLs are being resolved differently, depending on where the app is hosted: a) my computer's IIS 5.1 (Windows XP) or b) my host provider (which I'm almost sure runs Windows Server 2003). Behaviour 1 (the normal one?) - with...
I'm trying to make my button bigger when it receives focus: <html> <form name="myForm"> <button onfocus="width=200; height=200">myButton</button> <button>myOtherButton</button> </form> </html> Any idea how can I make it work? ...
When CSS and JS got popular, the big frustration was that every browser implemented it differently and only a limited set of "cool stuff" worked across browsers, or worked differently. Now we're making HTML5 popular, so it seems like we're about to embark on the CSS/JS incompatibility journey all over again, but now in a 3D, animated, a...
I have an input array like <input id='delete[18]' name="delete[18]" value="1" type="checkbox"> <input id='delete[19]' name="delete[19]" value="1" type="checkbox"> This Javascript code for check does not work.

I'm having problems implementing classes in mootools since I can't use 'this' when I send methods in say element.addEvent. Say I have this mootools class: var Dude = new Class({ highlightColor: '#f00', doStuff: function() { var parent = $('theParentId'); new Element('div', {'html': 'Click me'}) .i...
Dear all, I'm not sure if this is possible~ Say a bookmarklet that creates an embedded iframe loaded with a web application and there's a few urls in the web application. When urls are clicked, they are loaded into the current browser window which is running the bookmarklet. By default, the bookmarklet will be "gone" after that. Is the...
How might I convert my bind method to allow for both a single object or an array of objects (in this case several links) to have functions bound to certain events? Would be cool to handle it within the bind() method I think.. Any assistance would be appreciated var dQuery = function() { return { bind: function(obj, type, handler, de...
I'm a webdeveloper with an emphasis on server-side programming. What little I've tinkered with JavaScript, I've done with externally referenced files or event handlers, and the barest minimum of an initialising function call between <script> tags. As such it came as a surprise to me about a week ago that the data between <script> tags i...
