Hello. I have developed an application in PHP + Javascript. I'm using MySQL as database support. Every account for this app will come with a subdomain... so the client Stardust would have stardust.mysite.com.

I need to do a quick and dirty 'Country' --> 'State' drop down relationship on a web form. I only am concerned with the states, provinces, and territories for USA and Canada, and this will be a relatively lightly used form, so a pure javascript solution is probably ideal. ...
Background I would like to simulate the "active" behavior that most browsers support for links when they are clicked. For any element and event I would like to be able to add a css class to the element for the duration of the event. So in psuedo jQuery code I'd like to do this: $(".button").click(function() { alert('clicked'); }); ......
I recently was quickly shortening some method names in a javascript file and ran into a problem when I converted one method name: Before: RefreshSevenDayGrid(){ // some stuff } After: 7Day() { // some stuff } I quickly discovered that the javascript no longer worked. I heard from several people that numbers should ne...
I've written C++ event-driven apps using MFC for GUI buttons, and I use HTML events like onmousedown to trigger some Javascript in a webpage. The idea of event-driven programming is intuitive when you are using the interface and events are hard-coded. I know how to use a function pointer in C, and I see how Windows uses them to run an ...

Within the gridview I have, I'm trying to make it so when the user checks a check box for the row the row is highlighted. Now, this GridView is striped (meaning even rows have one background color and odd rows have another). This code to do it is floating around the net in various forms... var color = ''; function changeColor(obj) { ...
I've come across a couple questions, such as this one, and I really have to wonder why "Use jQuery" seems to be the answer when somebody asks how to do something in JavaScript. I understand that jQuery can save you a lot of time, and can help you out a lot, especially when you are doing a lot of fancy JavaScript in your site. However, ...
I've been struggling with this for the past couple hours now and I really don't know what could be wrong. I'm simply trying to get Javascript to communicate text with Flash. I found this great example with this source http://blog.circlecube.com/wp-content/uploads/2008/02/ActionscriptJavascriptCommunication.zip I ran the html file local...
I want every cell in each row except the last in each row. I tried: $("table tr td:not(:last)") but that seems to have given me every cell except the very last in the table. Not quite what I want. I'm sure this is simple but I'm still wrapping my head around the selectors. ...

All I need is to be able to detect when text is dropped into a Textarea. I then take that text and do stuff with it and clear the textarea. There may be many of these textareas and very high UI expectations, so polling is a last resort. For IE, "onfocus" does the trick, since this event is fired after the user drops stuff into the tex...
