View 1 RepliesI'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.
How do I capture the keycode inside a <textarea> in NN6+ and IE5.5+? I don't
want to add add document.keyPress function because I only want this to
occure when a specific textarea is selected and not fire for every keypress
in the entire document.
<textarea onkeypress="captureKeys();"....
but I cannot get a reference to the current event so i can ask for the
keyCode. In IE I can check the event.keyCode inside my function captureKeys
but this is not possible in NN6+.
Does anybody of you have a good algorithm to capture when a value in a
textbox is changed? I'm using the keypress/keydown events but they seems to
be a bit inconsistent (IE and Mozilla). Basically what I want is to set is a
"isDirty" flag when a user has changed any value in the textbox (or in a
dropdown) and then if he/she tries to leave the record without saving I want
to give a save warning. Since I don't want set the isdirty flag if you for
example klick tab, certain F-buttons, arrows (up/down/left/right) etc I
tried to capture the keypress/keydown event and ignore specific keycodes.
Since there are several keycodes that should be ignored I was hoping there
is a better solution.
how to capture/display value from selected item of dropdown list into textbox. what i want to do is when user select multimedia course, the coursefee will display on (txtcoursefee)and user input the amount that student pay and when button calculate is click the balfee will display on txtbalance. my code here is still not working.

Below is the script and form fields I am working with. What I want to do is sum the two textbox fields and have the result show in the total textbox. The code works fine and the total textbox is updated with the value of form1.basic. The problem occurs when I add the "+ parseInt(document.form2.supporter.value)" code in the script section.

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.
View 1 Replies View RelatedCould 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 have requirement to move focus to previous button when onkeydown event occurs on tabout from current button. Below is snippet of code.

I am making a hta file, I have made a script in it to detect keydown but it never seems to work. Below is my code.
HTML Code:
function detect(){
if (event.keyCode == 27){
window.location = "1.htm";
}
else if (event.keyCode == 116){
return false;
}else if (event.keyCode == 117){
window.location = "2.htm";
}else if (event.keyCode == 119){
window.location = "3.htm";
}else if (event.keyCode == 120){
window.location = "4.htm";
}}
document.onkeydown = detect;
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.
[Code]...
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..
Let's say I have a page with a counter (with an initial value of zero) and nothing else.
Here's what I want to do:
1) I press and HOLD a key down
2) The counter goes to one
3) I let go of the key
4) The counter still reads one

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.
var KEY = {
UP: 38,
DOWN: 40,
W: 87,
[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?
$('#searchcontainer').keydown(function(e) {
if(e.keyCode == 40){
$('#searchresults .searchresult').eq(0).addClass('selected');[code].....
i have this jquery script on my photo galery page, it detects left and right key down on keyboard and acts uppon key down.
Is there any way to deactivate it when I click on a text area that is located below each photo? this must be a common issue I think...

<script type="text/javascript">
$(document).keydown(function(e){
if (e.keyCode == 37) {

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()
[code]....
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.
As the subject says it, is there a way to simulate a special keypress in JS
? In my case, on loading an HTML page, i'd like to set the cursor at the end
of the input text of an <input type=text ...> object. focus() sets the cusor at the beginning Any idea ?
Is it possible to change the part of the URL after a # symbol using javascript (and not anchor tags)?
ie. is there a way to change with a javascript function/event?
Is it compatible with major browsers?
