Disable Default Keyboard Commands
Apr 27, 2009
I am building an application that acts like a terminal command line. I want it to be fully interactable with the major keys on the keyboard. I am using Jquery as the base for the UI. There are two methods I am trying.
1. Using a textarea element.
2. Using a div element
If I use the textarea then I cannot utilise the tab button to create an indent as it move the focus away from the element. In addition to this, I want to use tool tips as the user type and I'm doubtful I could create this with a textarea.
If I use a div element then I cannot use the backspace button as it forces my browser to go back one in history.
I would also want to use the div tag to create the text field as tooltips will be easier to implement plus I could add line numbers using a list element placed within the div.

How can you disable/enable Javascript using a shortcut key on your keyboard? Can you create a shortcut key that can do this quickly for the user?

Should I disable the right click option or not? I have a gallery site, I don't want people to be able to copy the images with the default right click over an image. From a professional looking site point of view I suppose I would be messing with the functionality a bit too much, OR is it OK in this instance to disable the click. I know how to write the code to disable the click, but what I was thinking was maybe it would be better to leave the right click but change the menu options? I'm not sure how to change the menu options ere is a link to the site. [URL]

I heard or read that the next version of HTML will provide long-overdue drawing commands.
Which version of Firefox, Opera or IE supports such new fancy stuff?

I havent used java that much, and lately I updated from M$ java to SUN
(due to my bank).
Before, this worked:
<body onload="SetFocus(); window.focus();">
now, it does not. SetFocus() is included as:
<script language="JavaScript" src="mystuff.js"></script>
Though, this gives an alert:
<body onload="SetFocus(); window.focus();alert('hello')">
What is the difference and the trick here?

The problem I have is that the NETiom board will only accept single commands to the HTML server built in to the NETiom.
What I dould like to do is send the following commands, timed 500ms apart to switch off 4 outputs before initilising 1 of the 4 inputs.
The commands I need to send are : B01 B02 B03 B04 T01
These 5 commands switch off relays 1 2 3 4 beofre energising relay 1
OK the code I'm using currently is as follows which gives me the correct buttons and action upto the point of cancelling any of the first 4 relays before energising one.
The buttons I would like this action on are NE SE SW NW
Maybe the NE button calls a section of code which will send B01 pause B02 pause B03 pause etc etc

I am a self thought web developer and am constantly having problems making sure that certain commands are finished executing before others are started. My most recent problem is trying to append a large amount of data, to a div, then sliding it down slowly. Since that data takes a while to append, the system is doing both at the same time, therefore not giving me the slide down effect. Here is the code:
$('#SomeDiv').append(data);
$('#image1').animate({"left": "+=300px","top": "-=200px"}, "slow");
$('#image2').animate({"left": "+=120px"}, "slow");
$('#Image3').animate({"top": "+=250px","left": "+=300px"}, "slow");
[Code].....
Where "SomeDiv" is part of "cpage" and "data" is a large amount of images. I would like to execute line 1 and then all the other lines simultaneously. It is currently executing all of the simultaneously.

can you put an id into a server side include like you can other items using javascript?
I tried this putting the id name in the virtual address area but it doesn't work. I also tried replacing virtual with id instead still with no luck.
document.getElementById('dynstuff').src=content[newm]
<!--#include virtual="dynstuff"--><!--#include virtual id="dynstuff"-->
The error message says getElementById is null or not an object but it works fine with image ids and iframe ids. Can anyone tell me why this doesn't work?

I am looking for a way to put all CSS values on my selected elements back to its default. I was wondering if anyone has maybe done this before and if not has any idea's to get me started.
The idea is that when I use for example:
The elements within .setDefault will return to its default font/color/height/width etc... so basically all posible values.

It's pretty common to assign a click even to a <div> (or other tag), such as:
Code:
// JQuery
$(document).ready(function(){
$("div").click(function(){[code]....
Of course this event won't be accessible from the keyboard, which might be nice. Now if it where an <a> tag, you can do this:
Code:
$(document).ready(function(){
$("a").click(function(e){
alert("clicked");
e.preventDefault();
});
});
The click event will fire if you click the <a>, OR if you tab to it with your keyboard and hit Enter.My question is: is there a way to make elements other than <a> tags accessible in this way? I recently discovered if you define a tabindex on your div, such as <div tabindex="0">test</div>, you can tab to that div, but click events don't seem to fire if you use your keyboard. Are <a> tags the only tags that can work in this way?

I've been looking up lots of documentation and trying to work out a
cross-platform method of capturing a keyboard event and working out
which key was pressed. From what I can find, there doesn't appear to be
any standardised keyboard event interface other than this DOM 3 Events
W3C Working Group Note [1]. However, it is only a note and doesn't
appear to be implemented in any browser. Is there another standard that
I've missed?
The Gecko DOM Reference lists event.keyCode [2], but this doesn't appear
to be implemented in Firefox 1.0.2, as e.keyCode in the following
returns 0, regardless of the key pressed. Code:

I am trying to get this code to work in IE. It works on Firefox, but not on IE. Basically it blocks out scrolling the page down with space button, and registers up and down keys to run some code. The entire case statement including event registering and my code works completely fine in FF but it just won't work in IE (meaning that I can scroll down with space, and up and down with the up and down keys respectively).
By the way I put this function in the HEAD section.
window.onkeydown = function(event)
{
// No space scrolling!
switch (event.keyCode)

So, this code does what it's supposed to do (check an array for dis-allowed input and supply the appropriate keyboard for touchscreen users) but I was worried that maybe this wasn't the most succinct logic...
kb=2,kp=1;
for(var i in Setup.DisAllowed){
if(Setup.DisAllowed[i]==0)[code].....
Keeping in mind the Setup.DisAllowed array and APP.Module method are fixed in stone, would anyone recommend a better way to use the array to select the necessary keyboard?

Now, I have a script that has auto complete thing with the help of Javascript and DOM and AJAX, and I follow this tutorial [URL]
Well everything working great, but, I want 1 thing. When the Suggestion box is visible, and has all the options, and If I mouse over them, it will show the hover effect. I want to achieve the same with keyboard. Like if I press down for the first time, the first option will be selected, and then if i press down again, it will select (hover) the next and so on, and similar is the case with up arrow key. Now, when i press enter, the selected option should go to the text box as if I click on a item.

i have created a keyboard that works and inputs the values pressed into a text box, i have then tried to expand on this and create a keyboard with multiple layouts that dynamically change when a button is pressed, i have done this by having an iframe within the page and calling the parent function but it will no longer input the text into the textbox. The CSS styling also works in Safari but won't on firefox.

This is fine but if I want to open a menu with the help of a short key like control + some key and want to navigate the menu items using the arrow keys. Is this possible? Please let me know as early as possible.
