I am trying to assign the left and right arrows, but I cannot get the code to work. It would be great to get some help--I am a newbie to coding.

What I need is something as such (based on previous thread): I have a textfield and I want to limit the input to only numbers, letters and caps.
So the code is:
<input onkeydown="return testChars(event)" type="text" .../>
function testChars(e){
var keyCode = e.keyCode;
if(e.shiftKey && keyCode==53){
return false;
} //block "%"
//HERE BLOCK EVERYTHING THATS NOT a Letter, caps and numbers
if ( (keyCode > 64 && keyCode < 91) ||(keyCode > 96 && keyCode < 123) )//Letters and Caps{
return true;
}else if ( keyCode > 47 && keyCode < 58 )//numbers{
return true;
}}
The problem however using the onkeydown is that I would need to cater for every single possibility of them using SHIFT+1=*, SHIFT+2, SHIFT+3 etc. which would take forever. And I cant block Shift because they might use it for capitalizing letters.
Does anybody know why doesn't onkeypress catch up/down arrow keys
while it catches left/right arrows? My only supposition is that up/
down keys are used for moving between form elements, anyway does
anybody know any solution to this problem?
I have a little problem that i hope can be solved. You start to type in an <input> field and a list of results show based on what you type, I have a list of Airports in MySQL that is check for LIKE of what is typed in and the matches show that can be selected. But you can only scroll with the mouse and not the arrow keys.
Does anyone know how I may allow arrow keys as well as the mouse to select their choice?
Disable Arrow Keys I am creating an online flash gaming site, Aaron's Game Zone: [URL]Some of the games on it use the arrow keys, however IE also uses them to scroll the page. I am learning JavaScript and am trying to write some script to pervent the page scrolling up and down while playing a game.For example.Guardian Rock uses the arrow keys to slide around, at the same time the page scrolls.[URL]
Here is the script I've tried to write to pervent the scrolling:
<script type="text/javascript">
function KeyPressHappened(e){
if (!e) e=window.event;

Can someone help me get started on some browser-independent code for moving an image with the arrow keys? That is, if I press the up arrow, the image will move 10 pixels up; if I press the left arrow, the image will move 10 px left.

Im trying to learn how to scroll using arrow keys or hotkeys. Where you're able to use your arrow keys to move side to side and up and down.
Here are the 2 best examples of how it functions:

ffffound[dot]com (top right says hotkeys to scroll with)
Can anyone link me to how to script that? Or even if there's a proper term I should know about to search for tutorials..
I have three buttons on a typical page (sample page: [URL].. One goes to the previous page, one to the next, and one up a level. Can I link these buttons to 3 arrow keys to simplify navigation for the user? I thought this would be a common task, but I cannot find any canned code on the web to do it. I can code simple html, but don't know javascript.

View 2 Replies View RelatedI just create a neat little AJAX google suggest style drop down, using a scrollable DIV which contains a table, now the user wants to be able to use the arrow keys to navigate the table.
Does anyone know how to do this or know of an example / tutorial on how to do this? Each row and cell has it's own unique ID.
I got this problem while disabling Up/Down arrow keys in Mozilla firefox browser useing javascript Given a standard HTML select/option box, I can capture any keypress while the select has focus and stop the select�s option list from changing values in IE but not in Mozilla.
[Code]....
In IE and Mozilla I have no trouble capturing the keyCode, and in IE I can prevent pressing a letter "D" and Up/Down arrows from making the list move to Dead, but the select list will drop to �Dead� in Mozilla. I've tried attaching the event handler to keyup, keydown and keypress, but have yet to find a way in Mozila to capture the keypress and prevent the select list from changing the current selection.
A client would like me to implement spreadsheet-style form traversal using the arrow keys on a keyboard, i.e. left arrow would submit the entry for that field and then move left by one field on the form.
The form is managed by my PHP code. Does anyone have a browser-independent method of doing this please?
All input fields in the form are single line text fields.
I am implementing an "auto complete search box" much like the one Google uses. If you notice on Google, if you type a letter and the drop down box appears with the predicted terms, you are able to navigate in and select from those terms using the arrow keys on your keyboard.
In my implementation, the drop down box is really just a DIV. It is separate from the search box. How do I replicate the Google behavior?
I want an event to be triggered when I use left and right arrow buttons like this:
Code:
$(document).keypress(function(e){
if (e.keyCode == 39 && key_pressOK) {
e.preventDefault();
$("#next").trigger('click');
key_pressOK = 0;
}});
This works on firefox, but not chrome, haven't even bothered checking the other browsers since it didn't even work on chrome.
I'm trying to get a next/previous arrow to float over the right/left edges of a slideshow div. I'm using to absolutely positioned divs to contain the next/previous buttons but for whatever reason they refuse to display above the slideshow div. Is there any way to get controllers to float over the cycle container?
Here's my code and if you give it a try you won't see the floating next/previous buttons unless you change the 'top' values for #next_btn and #prev_btn in the CSS to be greater than the height of the image (change to 410 to see them in my example):
<style>
#container {width: 500px;}
#container {position: relative;}
#next_btn {position:absolute; top:10px; right:5px;}

I am trying to setup a textbox to only accept specific keys. The problem is, some of the Function keys are reading as the same values as letters.Ex.
112 - F1 - p
113 - F2 - q
114 - F3 - r[code]....
Is there another way to allow the function keys without enabling all matching letters as well?
I am making a php/mysql epos system for my shop which will be run from a browser on my shop PC. I have large buttons which I would like to be able to 'click' by pressing something like the F-buttons at the top of the keyboard. Is it possible to override the standard button shortcuts for a web page. This is only going to be on my shop computer so accessibility is not a problem.

I have a form with many, many, many 'input type="text"' elements in it. I'd like to be able to dynamically add an 'onKeyDown' event listener. Here's what I've got, so far (I know it's wrong.)
Code:
function addEventToElement(formName,tagName,typeName,eventName,eventAction) {
thisForm = (typeof formName == 'string') ? document.getElementById(formName) : '' ;
thisTag = (typeof tagName == 'string') ? tagName : '' ;
thisType = (typeof typeName == 'string') ? typeName : '' ;
thisEvent = (typeof eventName == 'string') ? eventName : '' ;
thisAction = (typeof eventAction == 'string') ? eventAction : '' ;
if(thisForm != "") { // If elements are in a form, make sure ONLY those elements are affected
elem = new Array(); elem = thisForm.getElementsByTagName(thisTag); // array of all items of [tag]
alert(elem.length);
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
else { // Otherwise, any/all elements in a document/body will be affected
elem = new Array(); elem = document.getElementsByTagName(thisTag); // array of all items of [tag]
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
if((thisEvent != "") && (thisAction != "")) {
for(i=0;i<elem.length;i++) { // All elements are picked - let's apply some attributes
document.getElementById(elem[i].id).addEventListener(thisEvent,thisAction,false)
}
}
}
HTML Code:
addEventToElement('form_name','input','text','keydown','return numbersOnly(event,this);');
I have come across a problem with the onKeyDown event in some of my forms.
I'm using onKeyDown in <form> as a standard method to open my help screen
system throughout my system, but I have discovered that If I have a
<div></div> section somewhere and then load the contents of it from another
file using innerHTML after the main window is loaded, the onKeyDown event
doesn't trigger any more.
I'm using IE6 and the structure is:
I have the below code to block the view source but its not working for me.
<html>
<head>
<script language="javascript">
function onKeyDown() {
// current pressed key
var pressedKey = String.fromCharCode(event.keyCode).toLowerCase();
if (event.ctrlKey && (pressedKey == "c" ||
pressedKey == "v")) {
// disable key press processing
event.returnValue = false;
} }
// onKeyDown
</script>
</head>
<body>
<DIV align=center> .....
I want to use an onkeydown() on my web site and the web site to know which key I pressed. Specifically know I pressed the arrow keys and store which key was pressed in a variable. Must work on all browsers.
