• Can I declare the same value for two attributes at once

  - by graphicdivine

  For example, for accessibility reasons I want my onfocus and onmouseover to have identical values. For the sake of maintainability I want to declare this once only. What I'd like to be able to do is this: <a onmouseover,onfocus="assist('hello');">linktext</a> But, of course, that would be too easy, and doesn't work. What's the best way I can achieve this DRYing out of my tags?

• is it possible in javascript to create shortcuts with sequence like 123,345 instead of combo?

  - by frankB

  I already used some script to implement the shortcuts in my web page but i was wondering if could be possible to associate some combination not syncronic like Ctrl+X but more like a sequence typing 1..2..3 or any other combination to execute a script... lets assume this example: you have a long list with numbers: you could type 3..5...6, so you can go to the item 356 passing trough the item 3 then 35 then 356 more or less like when you type while selecting a select box i hope it was clear, id not easy to explain...

• Is it possible to use a string variable to reference an element in Javascript?

  - by somerandomguy

  Here's the quick version of the code as it stands right now: function foo(attributeName, someJSObj, key, newValue) { someJSObj[key].attributeName = newValue; } Obviously this doesn't work, since it just creates a new element called attributeName. Is there an easy way to dereference the attributeName into the string that represents some existing attribute on someJSObj?

• Rotating blocks in JavaScript.

  - by Alvin SMith

  I'd like to create a JavaScript web app that makes blocks appear on the page that can be dragged around by the user. If I used DIVs with background colors, it would be easy to rotate them by 90 degrees at a time. However, if I wanted to rotate them arbitrarily, how could I accomplish this? I'd rather not have to resort to Flash, images, or HTML5.

• "Share this on..." URLs

  - by Andrea

  I have to create a bunch of these "Share this on" Technorati, Digg, Facebook, Reddit, del.icio.us, StumbleUpon, MySpace and so on. It is very easy to find online icons for this task, but it is a little more difficult to find what URLs I should link. Is there any updated list of all these services? Of course I could copy them from other sites having this, but I am not sure they are updated, and moreover maybe there is some GET parameter I want to set differently.

• FLEX: How to know when a dialog created throw PopUpManager Closes

  - by WeeJavaDude

  Is there a easy way to figure out consistently when a Dialog closes that has been created through PopUpManager. I would have suspected some type of message or callback mechanism, but there does not seem to be. In one case I use the WindowTitle component and event that only fires the CLOSE if someone presses the close and give no message when the dialog actually closes.

  How to automatically close process that uses more that specified amount of memory on windows.

• Is there a simple PHP development server?

  - by pinchyfingers

  When writing web apps in Python, it brain dead easy to run a development server. Django and Google App Engine both ship with simple servers. The main feature I'm looking for is no configuration. I want something like the GAE dev server where you just pass the directory of the app as a parameter when the server is started. Is there a reason that this is more difficult with PHP?

• Is there any simple way to determine when the popup menu was dismissed?

  - by Alex Jenter

  I'm displaying a popup menu using TrackPopupMenu and would like to know when it is dismissed via clicking outside of it. I've looked through all the menu functions but didn't find anything useful in this regard. Spy++ told me that no window message is sent in this case. So, is there an easy way to do it without installing a mouse hook? Thanks!

• Best javascript i18n techniques / AJAX - dates, times, numbers, currency

  - by John Vasileff

  For server side generated content, i18n support is usually pretty easy, for example, Java provides extensive i18n support. But, these rich server side libraries are not available within the browser, which causes a problem when trying to format data client side (AJAX style.) What javascript libraries and techniques are recommended for performing client side formatting and time-zone calculations? Also - beyond simple client side formatting, how can consistency be achieved when performing both server side and client side formatting?

• Getting a list of all children of a given commit

  - by intuited

  I'd like to run git filter-branch on all children of a given commit. This doesn't seem to be an easy task, since there doesn't appear to be a way to tell git rev-list to only return children of a particular commit. Using the .. syntax won't work because it will also include the parent commits of any merge within that range. Am I missing something here?

• How to use vim's syntax files in emacs to color the text

  Are there any snippets to make emacs use the .vim syntax files found in /usr/share/vim/vimfiles/ for coloring text. Many applications like conky have the vim syntax files like "conkyrc.vim" for vim but not for emacs. So is there an easy way to use those files rather than rewriting a new language-mode for each of those available in vimfiles directory.

• Restore WindowState from Minimized

  - by tbetts42

  Is there an easy method to restore a minimized form to its previous state, either Normal or Maximized? I'm expecting the same functionality as clicking the taskbar (or right-clicking and choosing restore). So far, I have this, but if the form was previously maximized, it still comes back as a normal window. if (docView.WindowState == FormWindowState.Minimized) docView.WindowState = FormWindowState.Normal; Do I have to handle the state change in the form to remember the previous state?
