I 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.
I have tried to write a wait function but it seems like it will not brake the while loop. I tried two different solutions. Can anyone tell me what I am doing wrong, and come with another suggestion? If I call the function like this: wait(500); it should wait 500ms right?
function wait(time) { while(1){ setTimeout("break;",time); } }
function wait(time) { var flag=0; while(flag=0){ setTimeout("flag=1;",time); } }
i am using netbean to develop a registration form.As this i want to know what is the coding to check input of text, integer, email , so i can restrict what they input..
I need to get the object that was just clicked, to insert into a JavaScript function. I've tried "function('this')" and similar things, but it doesn't work.
I have 3 select pulldown boxes where a user will select a year (either 2002 or 2001), a week (one thru 52), and a database (short data or long data). But if a user selects a week that is less than 4, the 3rd select pulldown will only show the choice of "short data", as they will not be able to select "long data". Is it dynamically possible in javascript to program a third pull down in this fashion?
how to achieve the same affect with the code pmw helped me with several months ago this time around im trying to achieve the same affect instead of displaying one image im wanting to display text but stuff like this depending on what is selected once again it will display the following.the url for this is once again here.how much space,bandwidth,ram for gaurantee and burstable ram and ips etc.. now how can i do this using the following code below.
So I have a nice little hand rolled Ajax call to my server pulling a list from the database and displaying it in a drop down list dependant on the user input. Aka Google suggest. I am wondering if the quickest way to do this is to call the database each time with Ajax and search the results with the input, or to write an xml from the database and search that. Then when the Database is updated rewrite the xml file.
Am I underestimating MYSQL again? Or not, and I feel it would be good practice to write the xml file because it will essentially mean a lot less database calls. But I don�t know how fast searching an xml file would be in comparison to a db call. The results from the database are say 500 entries anywhere between 10 - 100 characters each. I want to know A. The best way to do this B. Lets say the site will have pretty high traffic so I am looking for it to be as tweeked as possible. I can test but thought at the end of my week it was worth seeing what peoples advice is.
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'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.
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 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...
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:
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{
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.
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---
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 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:
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.
