I have a requirement to force the pageUp and pageDown keys to function the same as the arrowUp and arrowDown. I believe I'm ok with IE but have issues with setting the value for FireFox ...specifically line: evt.which=38; and line evt.which=40; -the "which" seems to only have a getter-
try{
if (window.document.addEventListener) {
window.document.addEventListener("keydown", reviseKeyFunctions, false);
}else{
[Code]....
How come this code ...
$(document).keypress(function(event) {
console.log(event.keyCode);
});
returns 0 after pressing the key 'a' in FireFox but 97 in Chrome?
Here is an answer for those who are looking for a keystroke evaluation
script that works in Internet Explorer (IE 5.5, 6.0, 7.0 for PC--IE
4.0, 5.2 for Mac), Mozilla Firefox (Windows, Linux, and Apple
Macintosh), Safari, Opera, and other off-brand web browsers.
I have gone through many groups trying to find code that didn't break
in Firefox--yet still worked in other browsers. Although many people
give input on this topic, few are correct in their handling of the
events to give the correct results across the board.
I am a Webmaster, and although I have worked with much JavaScript, I do
not claim to be an expert on this topic--so feel free to post any
improvements that you can make.
Here's the test code, this snippet designed to force numeric-only input
in any browser, with the exception of a couple keys that are still
needed for form navigation (such as Tab--although this can be tailored
to your needs by adding more exceptions):
---SNIP_01---
<script language="JavaScript">
function CheckNumericKeyInfo($char, $mozChar) {
if($mozChar != null) {// Look for a Mozilla-compatible browser
if(($mozChar >= 48 && $mozChar <= 57) || $mozChar == 0 || $char ==
8 || $mozChar == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
else {// Must be an IE-compatible Browser
if(($char >= 48 && $char <= 57) || $char == 13) $RetVal = true;
else {
$RetVal = false;
alert('Please enter a numeric value.');
}
}
return $RetVal;
}
</script>
---END_01---
This function would then be called as follows:
---SNIP_02---
<input type="text" name="over_figure" id="over_figure" size="5"
onKeyPress="return CheckNumericKeyInfo(event.keyCode, event.which);"
value="">
---END_02---
I have personally tested this on PC, Mac, and Linux systems in every
Web browser that I can get my hands on. It's far easier than the other
scripts that I've found, and you can just add "alert('keyCode: ' +
$char)" to find any other keycodes you might want to allow if you don't
know them off-hand. Obviously there is room to add a larger exception
list if you have need of it, and it might be better to just set $RetVal
to TRUE in the else and add an else if for IE, but my use didn't
require it.
I hope it saves someone some time!
I'm trying to figure out what key the user pressed using a Danish
keyboard layout. charCodeAt returns the correct number, but
event.keyCode returns a wrong number, when using one of the keys that
are different on a Danish keyboard layout. "-" returns 45 and 189
respectively. Etc. (The input-field in the sample code below displays
the right character).
I've tried setting the lang-parameter to 'da', but it doesn't make a
difference.
sample code:
<input type="text"
onkeyup="alert(this.value.charCodeAt(this.value.length-1));alert(window.event.keyCode);">
Am I missing something, or is the event.keyCode in IE hardcoded to an
english keyboard layout? Is there a way to automatically convert the
event.keyCode so it corresponds with the users keyboard?
I have:
<div onkeypress="go(event)">...</div>
and:
function go(event) {
alert(event.keyCode);
}
but I always get 0 for the keycode.
I must be writing this wrong.
<script type=text/javascript >
$(document).ready(function() {
if(event.charCode || event.charCode !==13) {
[code]....
I am trying to use the jquery keydown event.I wan to fade in a div that is a form then when the user presses keycode 17 meaning control key this div and form will fade in at the center of the screen.here is the code I have:
<html>
<link rel="stylesheet" type="text/css" href="/home/main.css"/>
<script type="text/javascript" src="http://www.domain.com/pngFix/jquery-1.3.2.min.js"></script>
<script type="text/javascript"[code]...
This is in a php file and echoing the code. So the " " ignore it it's just saying to php that those are to be echoed as " " This code isn't working. I would press control key but no fade in occurs. I include this php file to all my websites webpages which are php files.
how to avoid temporary (local) variables to reassign this.Example as follow:
function Test(id){
this.id=id;
this.init=function(){
// some initialization go here
[code]....
This is terrible because it breaks the structure, and so many local temporary variables will be instantiated (possibly they will eat up the memmory).However, this type of reference is just so popular in jQuery, and they got a beautiful solution. Example:
$('li').each(function(){
// Do with $(this). This is beautiful, but I don't understand how could they make this scheme.
})
The keyCode of '&'=55 and the keyCode of ƍ'=55 also...
How can you know what a person typed if you get the same keyCodes?
keyCode and which will get the same value, so anything different?
<script>
$(function() {
$(window).keydown(function(e) {
console.log(e.keyCode);
console.log(e.which);
});
});
</script>
I want to overwrite the CTRL+S key via 'onkeypress' so, that the
browser doesn't recognize it as 'Save page as ..' command.
I assumed, that calling 'evt.preventDefault()' in my event-handler
would be sufficient. It isn't.
I have a 3 textareas that when the user presses the spacebar I would like for the code to execute a TAB to move between them instead. My code works if I make the replacement keycode an number or letter but it wont work if I use TAB. The browser is IE. code...
View 4 Replies View RelatedI got this (piece of) script from 'DHTML Utopia - Modern Webdesign - Using Javascript & DOM'.
function aKeyWasPressed(e) {
if (window.event) {
var key = window.event.keyCode;
} else {
var key = e.keyCode;
}
alert('You pressed the key: ' + String.fromCharCode(key));
}
It is example of adding an eventlistener to a textarea. The events works alright, but when I press 'a' the alert gives me 'A', when I press Ǝ' I get 'h', when I press Ɔ' I get ''', when I press 'à' I get Ɔ', .... Has probably something to do with the fact that I don't live in the UK or
USA. But it shouldn't matter; a key is a key.
Basically we are trying to simulate the tab key when the
down arrow key is pressed. (we know there are other way
to control focus flow but we use a lot of dynamic jsp fields,
that will make the flow control a nightmare, we just want
basic tabbing from the arrow key)
1)We are able to capture a onkeydown event and reasign it with another
key value with no problem within an html document without a form.
example:
var ieKey = event.keyCode;
if (ieKey == 40) {
event.keyCode = 9;
}
however as soon as we insert a form tag in the document, this stops
functioning. The asignment seems to be fine as an alert clearly shows, but the
instruction seems to be ignored. Code:
$(document).keydown(function(e) {
console.log('key code is: 'e.which);
});
I know how to find out which key user use, but how to do it when they use combination key? for example: "CTRL + C", "CTRL + V" and so on.
I have an input field with onkeyup event that displays the code of the key the user pressed. The thing is, this works for all the keyboard buttons except for the ENTER key.
View 7 Replies View RelatedI need an event that checks if the size of a DIV has changed. The "resize" event works in IE but not in FF. Or, more precisely, The "resize" event works in FF but NOT for resizing DIVs. Is there an event that works like the "resize" event but also can be used in with DIVs in FF?
View 2 Replies View RelatedAfter spending hours trying out many different examples that supposedly work with IE and FF, I've decided to post here :)
This is the code I'm using to catch the down arrow:
function is_int(event)
{
var Key = event.keyCode ? event.keyCode : event.which ? event.which :
[Code].....
And called using the following on the text input of a form field:
onKeyDown="is_int(event);"
This works in IE but still not in Firefox (3.5.7). Surprised as it has the .which in there - I thought this is what FF needed?
I am doing some showing and hiding of unordered lists for menus. I like CSS and so I swap the id of the unordered list to either show or hide the <ul>. The code works fine in Firefox but not in IE6. I start with the <ul> hidden using <ul id="SubMenu1Hide">. I attach the evens to the onmouseover and onmousout events. The bug happens in IE when I rollover the element with the event attached it does not show or disappear.
The <ul> seems to stay hidden like it is the default, it will never appear. Here is the weird thing. If I start with the id="SubMenu1Show" the menu shows as it is supposed to, stays visible when I mouseover and then disappears when I mouseout. It then continues to work as it is supposed to, appearing on rollover and disapearing on mouseout.
I want the submenus to all stack on top of each other on the page and be hidden by default then only show when you mouseover it's main menu heading. Here is the code:
with the equivalent code of this in firefox?
<html>
<head>
<title>Event Handling</title>
<script type="text/javascript">

I have come across a problem that seems common with firefox and the use of event. I have a simple javascript function which trys to determine the element that an event was acted upon:
Code:
This is called on click of a input:
Code:
This seems to work correctly for every browser except firefox. A quick search online and all the fixes seem to include:
Code:
But when I debug this function, neither e or event are defined, am i overlooking something really obvious?
the working code is : $(document).keydown(function(event)and I found out that it's not working on Firefox only on IE and Google Chrome...
View 3 Replies View Relatedi want to handle keyboard and want to replace keycodes like when user enter / press key a = 65 I may able to change and show in textbox b= 66.

I am trying to retrieve the keycode that was pressed while an input is selected. Here is my code:input.onkeyup = function() { func( this, event ); }

My original idea of two trains, however pictural it was, appeared to be
wrong. The truth seems to be even more chaotic.
IE implements its standard down-up model: any mouse event goes from the
deepest visible element to the top. By carefully studying fromElement
and toElement properties, one can handle events on any point of their
way up.
NN/FF implements a "Russian hills" style: mouse events go first
up->down (window->deepest element), and right away after that it goes
down->up (deepest element->window). On theory you can handle events
during any phase on any level. On practice this implementation has some
major flaws. I don't have NN handy right now, but in FF we have:
Code like :
-------------------------------
<img src="xxx.gif" id="top_menu_4" onclick="main_menu_select(this)">
I want to remove the onclick event:
-------------------------------
window.$ = function(name)
{
return document.getElementById(name);
};
$("top_menu_4").removeEventListener("onclick", main_menu_select,
false)
But it can't work in Firefox
