minor modification to 'show lang attributes' function

The 'show lang attributes' function didn't pick up the 'hreflang' which it should, so now it does. thanks to Iaco for pointing this out.I have now unmodified it because i was not thinking clearly, i became confused about the hreflang. thanks again to Iaco for pointing this out.Another minor modification has been made (08/02/05) due to IE's lack of support for the ABBR element. that should be it for now..........

1 more function plus new additional documentation

The recent flurry of activity (additons to the toolbar) has been due to the preparation of a document called The Web Accessibility Toolbar and WCAG 1.0 which is now finished and published.

This document indicates which toolbar function (if any) is helpful in assessing conformance to the WCAG 1.0 Checkpoints.

Each time i looked a particular checkpoint I thought
"it would be good if the toolbar could help check for that"

and proceeded to try to cobble together some code to do it, or scrounge around for some code to modify or best of all hassle Sofia or JUn to do some development.The newest function is:Structure > JavaScript / New Window LinksIt Displays an icon next to links that contain JavaScript in the href attribute. The links are also given a dashed border and background colour.

it Displays an icon next to links that contain an onclick event handler and common words used in new window scripts in the href and/or the onclick attribute. The links are also given a dashed border and background colour.

It Displays an icon next to links that have their target attribute specified (_self & _top are excluded) . The links are also given a background colour.

Aknowledgement to Autark who created the script this is based on.

Thanks to Sofia Jun and Andrew Arch for their help and hard work.....

3 functions modified + 1 removed

The 'doc info > list pdf's' has been reborn as the doc info > 'list downloadable files' it still list PDF files, but also lists a heap of other downloadble files if found. Big thanks to Sofia Celic for allowing me and helping me to mangle her code in order to create this function anew.The frames related functions "structure > frame borders" & "structure > frame name / title" have been improved (now identify iframes if present)I have removed the "simulations > greyscale" function as it is a duplicate of the "colours > greyscale" function

Thursday, January 13, 2005

3 new functions added plus 2 modified

New functions have been added:
  1. 'Structure > Show tab order' - numbers (in tab order) and puts a background colour & border around all active elements on the page. If the element has a tabindex attribute this is indicated.Note: applets/multimedia/ image maps/iframes are treated as one increment in the tab order.
  2. 'Doc Info > Show DOCTYPE' - simple function that shows an alert box indicating the DOCTYPE (if present)
  3. 'Doc Info > Show Lang attributes' - Displays on the current page any lang attributes found along with their associated elements. With acknowledgement to: Bartimeus Accessibility Foundation

Also two functions have been modified, one has been removed.

  1. The 'CSS > CSS on/off' & the 'CSS > Inline styles off' functions have now become one:'CSS > Disable CSS'. this function now disables external style sheets and removes inline syles as well.
  2. the 'CSS> test styles function' has been updated to include a dropdown list of style rules found in style sheets associated with the page, which can be inserted into the edit area. the styel changes can also be cleared using the 'clear' button. The functions interface has also been prettied up a tad.

New Functions Added

2 New functions have been added to the toolbar:
  1. Show Image Maps : Checks for the presence of client-side and server-side image maps. if none are found it is indicated by an alert message. If image maps are found, they are displayed in a new window along with the associated area elements. This function was developed by my esteemed colleague Sofia Celic.
  2. Vischeck Colour Blindness Simulator (Deuteranope: common red/green): Submits the URL of the current page to the Vischeck Colour Blindeness Simulator the URL is processesd (may take a little while), a page will open with a link to the simulation (in a new window).

These functions will appear on your toolbar after the next (Weekly) auto update or you can force an update using the Accessibility toolbar options > update feature.

minor modification to functionality

I have removed the "hot keys" for IE options > toggle CSS and toggle activeX as some people were getting keyboard conflicts and inexplicable activation of these functions, which caused some people some grief as they didn't know why most web pages looked crap (crapper?). These functions can still be accessed via the keyboard by using ctrl + alt + S to open the IE options menu and then using the arrow keys to navigate through the menu items.See the list of "hot keys" for other functions/menus.

Function Update: Structure > Event Handlers

My friend and colleague Sofia Celic has been working on updating and improving some of the Toolbar functions (as well as the laborious task of improving the documentation). The first function to get the treatment is "Structure > Event Handlers" which now is much more robust and checks for event handlers and combinations of event handlers on a greater range of elements: The script has been extended to include checking of the following elements: table, th, td, span, textarea,img. It has been also been amended to insert an 'information bubble' instead of a 'warning symbol' for 'onclick' attribute without 'onkeypress' attribute.Many Thanks Sofia.....what's next?

Bug report: ID attributes and JavaScript variables

I have been flumoxed (not difficult for me) as to why some functions have not been working on some pages. I have worked out why..... If a HTML element in the page contains an ID attribute with the same value as a variable name used within a JavaScript based toolbar function, it won't work, thankfully it don't happen too often. So I will need to go through the process of updating the toolbar scripts with more unique variable names....

real time CSS editor bookmarklet (alpha version)

I have been working on an updated "CSS > test styles" function for the toolbar, the original was created by Jesse Ruderman. i have always wanted to beef it up and include some extra features, which I have now done. The user can now insert new and existing style declarations on the fly and see the changes take effect instantly, the changes will affect all pages on a site as long as the css editor is open. I will incorporate it into the toolbar eventually, it is available as a bookmarklet for now [IE only] CSS editor bookmarklet (to save right-click and add to favourites). Think IE is crap? An excellent CSS style tweaker for mozilla/firefox is available at slayeroffice.css editor user interfaceComments on the css editor appreciated....

(More on) Keyboard navigation conflicts

A few users have reported odd behaviours occuring with the toolbar keyboard commands, as mentioned previously I have been hassling JUn to include a function to disable shortcuts, which he has now done.

While I don't plan to include this function [along with a bunch of others] until the next release in the installation package, but if you are experiencing problems you can download the test version of the dll and xml files [test_key.zip, 268Kb] which includes the hot key (de) activation function:

Once downloaded unzip and place these files in the folder where the toolbar is installed (they replace the dll and xml files that are currently there). Be sure that you have all instances of IE shut as you will not be able to overwrite the dll file with any IE windows open. Now when you open up IE in the toolbar options menu you will be able to turn on/off hot keys.Note: The update function has been disabled in the test version.The test version is the English language version only. It will not cause a problem to overwrite other language versions.

(More on) the Toolbar and XP SP2

It appears that Toolbar "Tools > View Source" function no longer works when SP2 is installed, we will investigate this and either modify or remove the function for the next release.Sorry for the inconvenience........

The Toolbar and XP service pack 2

Users have reported that the toolbar stops working or malfunctions when XP service pack 2 is installed.
"I thought that you might like to know there is a small issue for users who use the toolbar and upgrade to Windows XP SP2. The problem is small, and no doubt could be fixed by fiddling about in the Registry. However, post SP2 when you click on 'View Source' on the 'Tools' menu IE reports that the site cannot be found. The right click normal route still works."
I will look into this........A user has also reported:
"The toolbar Appeared on my computer to be disabled by the install of XP service pack 2. Am I alone? "
Then they wrote again:
"Re-installed with the latest version fixed the problem. (Was using 1.0 before SP2 upgrade)"
So if you are having issues after installing SP2 try uninstalling/re-installing the toolbar.

Suddenly the toolbar started throwing errors...

On Friday (3/10/04) I did a bad thing; I deleted all the toolbar related files from the server, this would have had a temporary detrimental effect upon all versions of the toolbar, being used on friday afternoon. I quickly sorted out the problem, sorry for the inconveneince..........

Frequently Asked Questions

1. I tried to install the accessibility toolbar and it ran through the setup program but there is no toolbar appearing in IE??

a few things to try:In the internet explorer menu ensure that:
  1. view > toolbars > lock the toolbars is unticked.screenshot showing the internet explorer 'lock the toolbars' sub menu item.
  2. Tools > Internet options > advanced > enable third party browser extensions (requires restart) is ticked.screenshot showing the 'internet explorer Tools/ Internet options / advanced / enable third party browser extensions.'
  3. view > toolbars > accessibility toolbar is ticked.
  4. open and close the browser a few times.
  5. look closely in the section of the browser that the toolbar should appear as sometimes the toolbar will initiall appear beside / partially obscured by other toolbars you have installed (e,g, google).screenshot showing the web accessibility toolbar obscured by the google toolbar

2. The resize function (e.g. 800X600) stops working....

This function is currently javascript based and i have noticed that, since installing the latest windows service packs, the resize functions stop working sometimes. So the toolbar has been updated by JUn so it no longer relies on javascript for this function, which solves the issue. The update will be available next week (about the 3rd of august).

3. Why do I get an error when I close a window in Internet explorer?

This is an issue with some browser version/operating sytem combinations, it occurs sporadically, we are working on a fix for this. we have implemented a partial fix that reduces the problem, but have not completely sorted it yet....

Many thanks to Jim McPherson who has been helping us with the testing of the dll's

4. when opening the IE-Browser i get an alert with the following text: IEEXPLORE "out of system resources".

And in the Toolbar (EN 1.0) any button icon (either this one of the CSS or this one of the Structure etc.) appears destroyed, i.e. not as a clear icon, but as a black or white spot. I'm using XP.....

Resource shortage happens in XP if the user has many applications open at once. the toolbar itself uses a small amount of system resources, but if resources are insufficient, drawing of icons will not be able to be done. If you only find this occurs when you only have a few applications running please contact me with details of the error.

5. Why does the toolbar only work in IE?

  • There was a gap in “the market,” no tools comparable to those available for Mozilla were/are available for IE.
  • Our programming expertise is limited (if somebody wants to work with us on versions for other browsers/operating systems we’d be interested),
  • Our resources are very limited as this project is unfunded so we work on it between paid work and in our spare time
  • While some people realise that there are better browsers than IE out there, their uptake is still very small, and my original idea was to raise awareness of accessibility issues and provide the tools to “the masses.”
  • For better or worse, many assistive technology users use IE for web browsing, so I tend to use it for accessibility testing and browsing due to this circumstance
  • What time I have had to work on developing the toolbar has so far been directed at improving the functionality and collaborating with others to create versions in other languages
  • A great web developer toolbar for mozilla/firefox is available from chris pederick

Keyboard navigation conflicts

Some users have reported issues with the key combinations designated for keyboard navigation of the toolbar menus, and their particular operating system or other software settings.
" On swedish keyboards the @-sign is produced with the keystroke Alt+2. In other words, it's exactly the same as the shortcut for the resize menu in the toolbar. This means that whenever I enter an email adress in a form field on a web page, the resize menu pops up and hinders me from typing."

A quick fix is to edit the accessibility_toolbar.xml file (open in a text editor), which you will find in the folder you installed the toolbar in.

You can remove or modify the attribute 'Accesskey="2" from the resize button element:<button type="dropdown" caption="Resize" hint="Screen Resolution" Accesskey="2" image="resize.bmp">Note: when you use the toolbar update function the xml file is overwritten.

I am hassling JUn to include a function to disable shortcuts (soon) and am also looking at function customization feature (don't hold your breath for this one)

Thanks Henrik for bringing this issue to my attention.

web accessibility t-bar living peacefully with the Google bar, amongst other things...

Some users have encountered a minor issue (me included) with the google bar:

" When I uncheck View>Toolbars>Google, it is the Accessibility Toolbar that vanishes from sight, and when I uncheck View>Toolbars>Accessibility Toolbar, it is the Google toolbar that disappears from view!"

This appears to be a general problem with the ie toolbar menu. Google has a simple fix for it (worked for me!). Thanks to Walter for bringing it to my attention.

A user has encountered this problem:
"When I right click on IE's toolbar, "Accessibility Toolbar" shows 3times.I tried uninstalling and reinstalling, but it doesn't remove theextra 'Accessibility Toolbar' choices."

I think this problem is because the ie registration system is a bit flaky (easy to blame it on microsoft), I have encountered similar problems with other toolbars / explorer bars. There are several free /shareware utilities out there, that may help you to remove such annoyances (see the links below), you can also try editing the registry yourself (not recommended unless you know what you are doing)

Thanks to Sam for pointing this issue out.

Is there a version for firefox or Opera??

See the FAQ's question 5.A great web developer toolbar for mozilla/firefox is available from chris pederick. The web developer toolbar has many similar features to the web accessibility toolbar, though it does not have the same emphasis on accessibility testing. It has some features that i would like to incorporate into the web accessibility toolbar in the future..........I found this extension for opera The W3-dev Menu "The W3-dev Menu is an Opera 7 customisation for web developers, providing handy shortcuts to validate and check their pages and some useful links to web standards and tutorials."which sounds promising.

Web Accessibility Toolbar JA 1.1 Released

JUn has released and upgrade to the Japanese version of the Web Accessibility Toolbar. Download from wrong html

Tuesday, August 10, 2004

Undocumented Features

The Toolbar has several undocumented features:
  1. The CSS button refreshes the page ('on click' or ctrl+alt+shift+3).
  2. The Structure button activates the Mouseover DOM Inspector ('on click' or ctrl+alt+shift+5) favelet from Slayeroffice.com, see the documenation on SlayerOffice.
  3. Selecting some text on a web page and activating the tools button ('on click' or ctrl+alt+shift+7) will result in the selected text being copied to the clipboard without formatting/styles. I find this useful when I want to copy 'plain text' to a word document. (Note: this is a bit buggy, doesn't cause any problems, but doesn't always work).
  4. The magnify button ('on click' or ctrl+alt+shift+m) resets the magnification to 100%.
  5. The AIS toolbar button links to http://www.nils.org.au/web_access.htm

The reason these features have not been documented are that they are features i have incorporated primarily for my own use, i am documenting them now so that if you come across them in unexpectedly you know what they are. I may add others as time goes on....

Monday, August 02, 2004
