Detecting Change Before Blur?
Jun 16, 2010
I have an input field where users can input a number, and JavaScript calculates a result and displays it on the page. In order to have the best user experience, I want JavaScript to perform the calculation whenever the number in the field is changed. However, the "change" event works only when the input loses focus.
I have added "keyup" as a second event for the calculation to be performed, which covers many cases of user input. However, this is still not perfect, because the user could paste a value into the box or change the value in some other way (i.e. clicking the up and down arrows on compatible browsers).
Is there an event that fires whenever the value in the input changes, regardless of the focus of the input? Is there some other way to work around this problem? It seems like this would be the kind of thing that would have a thousand hits on Google, but I can't seem to find anything.
My code:
Code JavaScript:
function onLoadFunc(){
if(document.addEventListener){
document.getElementById("wm_buy_amt_input").addEventListener("keyup",
[Code]....

I'm using a text area to display textual updates to a user from the server. I'm inserting the text at the bottom of the textarea and need to set the scrollbar to the bottom of the textarea after every update. The problem is that the onChange event only fires if the user actually changes something in the text area, not if it is changed by an ajax update.Does anyone know of a way to detect if there has been an update to a textarea that was NOT triggered by a user?

I am trying to detect whether a user entered text in a textarea
or hit the delete/backspace button (thus, erasing something). Once
that is detected, I would like to set "var bSaveRequired = true;". It
would be great if this function worked cross-browser -- IE 6.0 and
Firefox.

I am trying to change to change the background of a li element when its own class is changing
i tried :
$("ul#slide-nav li").each(function() {
if ( $(this).hasClass("selected") ){
$(this).css("background-color","black");
}else{
$(this).css("background-color","gray");
}});
This seems to be working I think., but once the class change again it doesn't work.. how can it loop for ever?

I have this code:
<select name="navigation" onChange="this.blur();doNavChange();">
<option>....
...</option>
</select>
I've also tried :
self.blur();
document.form1.viewButton.focus(); (tried to have it focus something else)
But still, the select box remains focused. Anyone have a method to fix this?

I wondered if there was a way to blur my whole site except a popup-div when a link is clicked - just like lightbox fades out the page, just with a blur effect instead:[url]...

A test script like this:
<A HREF="javascript:window.blur()">Blur Window</A>
put the window in the background in IE, when pushed, but it does nothing in other browsers like Chrome, Safari, Opera, Mozilla under Windows.
My real page is loaded from an external program (not the browser), if I dont have anything to tell the user, then I want the page to be "minimized" (or closed).
I am also able to close it in IE, but most people seem to believe that it shouldn't be possiple to close a close a window through Java, when it is not opened by Java.
Do I have other "minimize"/"close" options or how do I make blur work?

I'm triing to write script that close popup window, when user click outside the popup. Script below is working fine in firefox (v1.0.3), but not in IE.
I tried also to print hello but still the same problem firefox OK IE not. I think the problem is in event capture, but I can't fix it.
My script:
fotowin = window.open("", "foto", "width =100,height
=100,location=no,menubar=no,directories=no,toolbar =no,scrollbars=no,resizable=no,status=no");
fotowin.onblur = closeWin;
if (fotowin.captureEvents) {
fotowin.captureEvents(Event.BLUR);
}
function closeWin() {
fotowin.close();
//fotowin.document.write("hello");
}

I have these "editable" divs in my document. When you click them, a text box comes up and you type something and push enter. It changes what's in the div.There is also a blur event associated with the text box. When the user tabs or clicks away, it fires the blur event. Here lies the problem.I have other elements on the page that are clickable. I don't want those clickable things to fire their events if the user is clicking away from the text box, ie. the blur event. This isn't a problem is the user pushes tab, for instance.

I have the following code that should hide the dropdown part of a select box when clicked (don't ask why, this is part of a separate project). see a simple example below:
<script language="javascript" type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.1/jquery.js"></script>
<select name="select1" id="select1" onfocus="$(this).blur();">
<option value=""></option>
[Code]....
This all works fine in IE and FF but in chrome the options are still shown after clicking the element. I've been racking my brains for hours on this and, no matter what method I use, I can't get this to work correctly in Chrome.

i'm sure its been thought of before and i'm sure this is just gunna piss off the people who like to tab through their pages, but i just made a little behavior component file that stops any links from gaining focus on your page.
put this is the style section of your page.
<style type="text/css">
a { behavior: url("hidefocus.htc"); }
</style>
then put the attached file in the same dir. (hidefocus.htc) this is all it is
<public:component>
<public:attach event="onfocus" handler="blurry" />
<script>
function blurry() {
element.blur();
}
</script>
</public:component>
Note: since this behavior is stored in an external file, sometimes one instance of link focus can occur before the htc file can be loaded. if anyone has any tips on fixing that i'd like to hear'em.

I am doing a simple example of autocomplete textbox.Well whenever I am typing anything in the textbox it shows me the existing options as we know the default functionality of autocomplete textbox. Now I need that when I select one of the options from the autocomplete list droping below the textbox the blur function should execute so that the focus should get away from the textbox. I have tried document.getElementById('text1').blur() but it is not working in chrome and safari.

alert('**** yeah!');

I wonder if it is possible to make a JS blur effect on an image while it's moving.It probably is but I haven't seen it done before with JS, only ActionScript for Flash, I wonder what is the reason for this.So the way I have been thinking this could be achieved is by loading several times the same image giving them transparency and offsetting them a pixel or two from each other.

I know it used to not, but according to the blur() docs page "the domain of the event has been extended to include all element types." Is this true, or do I need to set up an onClick event for the body and check to see if the currentTarget or its parents are the div I'm trying to fire the blur event on?

I'm having problems with applying focus() to an element inside a blur() event handler. I get different results in different browsers. Specifically, IE and Opera seem to work fine, Firefox doesn't seem to do anything, and Chrome and Safari only do half of the job. Basically, I have an <input> with a blur() event handler attached to it. The event handler contains the code to apply focus to that same input, effectively disallowing the user to remove focus from the input.

I'm working with ClueTip and have run into some oddities.In particular, I want to show ClueTip when a textbox receives focus.The source shows me that I can use activation:'focus' for this and that will result in the cluetip showing on focus and disappearing on blur. Showing the cluetip is working fine, blurring is not.[code]

I have two form elements, the first one I'm testing for a specific content length (5). If there is not that much content in the box, I would like it to continue to have focus.
However my code below will not set the focus back.. What am I missing?
