I'm trying to detect the browser in that little box but It's not working. in between the <div> tags I have this code
<script type="javascript"> var browser=navigator.appName var browser_version=navigator.appVersion var version=parseFloat(browser_version) document.write("Detecting Browser..." + browser) </script>I don't even think I'm going to user the browser version so don't worry about that but I can't get this to work. I think I have it right, I was looking at the tutorial on w3schools. Can anyone see a problem? Am I leaving something out?
Edit: oh, very sorry. It seems my tiny little mistake is that script type should be "text/javascript". But now that that is figured out It shows that I'm using Netscape when I'm actually using Firefox 0.o
I have a parent element that registered to the keydown event.somewhere down the hierarchy I have a table and some buttons. It appears that after I press the buttons, I only get the keydown event in the parent after 3 key strokes.I put breakpoints and the event is simply not called.I'm guessing this is a focus issue, but couldn't make it work.
Could anyone shed some light on why this might not be working? Nothing happens when I press either the left or right key... Well, I have put an alert screen in there that does work - the problem is that I want the a#previous_link to be followed, but nothing happens!
I am trying to handle keystrokes on a text input element, in the keydown event. I need to know what character is about to be inserted into the string. I am able to get it for almost all letters, numbers and symbols using a combination of event.shiftKey, event.charCode, and String.fromCharCode() and some hard-coded lookup tables. (i'm aware that this is probably not going to work on non-standard/non-american keyboard layouts)
Unfortunately I can't get the character for a few: question mark, angle brackets, underbar, colon, and a few others. They all have charCode of zero, and nothing else in the event indicates which is which. Other than waiting till the element's value has changed (i.e. the keyup or keypress event), what can I do to tell which key is pressed?
I'm trying to get a keydown function to trigger an event... The same as the onclick event I currently have working. I got the buttons to work on keydown, but I cant get them to work just like the onclick. Trying to get them to do the same thing.
I currently have 3 jQuery events assigned to the document keydown, keyup and click.
Here is my code:
var logkeydown = false; $(function(){ $(document).keydown(function(e){ var key; e?key=e.keyCode:key=event.keyCode;
[Code].....
They toggle the boolean value of whether the keyboard key 'e' is currently pressed. If so, when the user clicks any of the site, I have a Thickbox fading in. This works great in Firefox and Safari, but IE7 begins to fade in the Thickbox (btw, I slightly altered the thickbox code to fade it in/out) but halts half-fade until the 'e' key is released.
I have a slight problem in FF3.5 that unbind('keydown'); is not working properly.. $("#q").unbind('keydown'); $("#q").keydown(function(e){ var code = (e.keyCode ? e.keyCode : e.which); if(code==40 || code==38) { var totalResults=$("#quick-search-results li"); var selectedResults=$("#quick-search-results li.qs-selected"); if(code==40) { var nodeIndex=($("#quick-search-results li.qs-selected").length<=0) ? 0 : $("#quick-search-results").index('li.qs-selected'); alert(nodeIndex); }}}); // end keydown
The above code alerts once on first keydown (with the down arrow key [code==40]), twice on the second, three times on the third and so on.. it worked fine in FF3 but a recent upgrade to FF3.5 seems to have broken the functionality..
The event which in the following keydown function code is not returning the correct key codes. I have checked this in Chrome using the developer tools and the console.log(e.which) statement in my code.
Im trying to add a class to an element when the down arrow is pressed using keydown but once you release the down arrow the class is removed from the element.Is this normal behaviour?
So I have an event handler for the KeyDown event in a Javascript file but for some reason it does not get called the first time a key is pressed. However, if a key is pressed or a mouse button clicked then the next time I press a key it does get called. Here is the relevant code:
........................... // Other stuff $(function()
I'm trying to get some elements enabled when a user start typing in a input field but without success. I try this codes:
$('#keyword').focus(function() { alert('Handler for .focus() called.'); }); $('#keyword').keypress(function() {
[Code]....
But none of them works. Just try in this page [URL] and start typing in "Buscar" (spanish) or "Search" (if you change to English) input and see that nothing happen and I don't know why. Note that I wrote alert() just for see if it works or not.
I have a code for the keydown event: -when you press the UpArrow key the image moves up -when you press the DownArrow key the image moves down.....and so on But don't forget that this is under the keydown event...so when I keep pressing the UpArrow key the image moves up but when I release the key the image still moves up. I already put the code $('myImage').stop(); on my image on keyup event but this doesn't do anything. There is a code to clear my memory from pressed keys or something?
When I upgraded to jQuery 1.7.1 (from 1.5.x), I found that an exception was suddenly thrown on every keydown event on an INPUT type="text". I still get the exception when I remove my change and keyup events. Previously I bound to these elements with .live, but I have the same issue with the new .on, so I don't think this problem is even related to my bindings.
The exception is as follows (from the custom WebKit frame where my script runs):
This occurs on line 3255 of jquery-dev-1.7.1.js, which reads:
I did some poking around and found that handleObj.origType is "keydown". There is no jQuery.event.special["keydown"] defined, meaning that the first part of the expression evaluates to undefined (there is no such thing as {}.handle). The second part of the expression, handleObj.handler, evaluates to true. The entire expression therefore evaluates to true, which can't be applied as a function.
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.
I'm trying to use JS to move the cursor from my user login text field to the password text field - I've put the onKeyPress() event in the user input tag but then I press the Tab key the cursor doesn't move -
function detect_tab_key() { var key_code = window.event.keyCode; if (key_code == 9) { document.forms[0].frm_password.focus(); document.forms[0].frm_password.select(); } }
I would to change the color of some td cells if there is text in it. Right now this code does the job, but it changes the color of evry table. I'd like to know a way to do this on one table in my page and not all of them.
var count='0'; var TDs=document.getElementsByTagName('td') var length=TDs.length; i='0';
Why is it that you need the return keyword? Where does the argument event come from?
I know it works, I just want to know why it works.
I've been looking at some refferences and can't seem to find an answer if someone could give me an explanation or point me to a website, that would be great.
I am trying to do something I thought would be simple in javascript, and I'm at a loss. First code is GOOD code, except that it does not account for the possibility that the button(s) in question do NOT exist. The second and third subsets are two of several attempts to do just that. Code:
