Previous Value Of A Changed <SELECT>

Jan 29, 2004

I have a form where users need to be able to change a particular value in a <select> but need to confirm that this is what they want to do under certain circumstances. I have the script firing up ok and prompting the user, but I'm darned if I can figure out how to undo the change if required.

What I want to do is something like document.form.object.value=document.form.object.oldvalue but I have no idea what the correct properties are.....

So, how do you roll-back the selection in a <select>?

Go To Top Of Page - Hide The Google Player Until An Onclick Event Actually Occurs

Jul 22, 2009

Here's my page.

[url]

I'm having 3 small issues with the page as it is.

First, I'd like to hide the Google Player until an onclick event actually occurs.

Second, at the moment, there's only an onclick for the image maps over the tracks list, and no href, which means the cursor never changes to the finger cursor, letting folks know there's a link there.

Last, when you click on a link, I'd like to the page to move its focus back to the top of the page (not reload, obviously). Instead, it just stays where you are, and the user has to manually scroll to see the full album art graphic.

Here are the relevant parts of the code:

JQuery :: Live() Event Doesn't Refresh The Class Of The Event Which Was Changed Dynamically

Jul 4, 2009

I got this problem with live() event.I have used it as follows.

$(".addressDiv span").live("mouseover", function(){
//clickable function here......
------------------------
});

I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.

JQuery :: Triggering Event When Checkbox State Is Changed By Another Event?

Jun 27, 2011

Is there a generic way to fire an event when the state/value of a checkbox is changed by another event - i.e. not a user action. In this scenario, I have a set of checkboxes with a "select all" checkbox. I have the code written such that checking or unchecking the "select all" checkbox updates the state of all of the checkboxes below.

The extra requirement here is that some of these checkboxes have "children". So, when you check one of these, its children are automatically checked as well. So, what I need to do is check the main "select all" checkbox, which would then check all of the immediate children, which would then check all of their immediate children. I tried both an onchange and onclick event, but neither seem to be firing.

<head>
<script src="/scripts/jquery/jquery-1.3.2.min.js" type="text/javascript"></script>

Applet Event Handlers Changed With Java 1.4.x?

Jul 23, 2005

I recently "inherited" a project which involves an applet on a web
page, and some Javascript event handling functions. The handler definition looks
like this:

<SCRIPT LANGUAGE=javascript FOR=Foo EVENT=mouseReleased>
<!--
Foo_mouseReleased();
//-->
</SCRIPT>

where Foo is an applet with parameter FiresScriptEvents set to TRUE.
The function Foo_mouseReleased() is a simple javascript function that just
alerts a fixed message so I know it's been called.

When I run this applet in a vanilla IE5.5 or IE6, it does exactly what
I expect - when the mouse is released, up pops my alert. BUT when I
run it on the same browser with Java Plug-In 1.4.2 installed, I don't
see it. Is there some compatibility issue with 1.4.x? Can the code be
changed relatively simply to work with both VMs, or am I looking at a
big rebuild to support browsers both with and without the plug-in?

JQuery :: OnChange Event - Web Application - Each Blur Event Makes A Call Webserver To Store Value Of Textfield

Jan 21, 2010

I'm currently facing a weird issue with the onchange event. I have a web application where each blur event makes a call the webserver to store the value of the textfield. I only want to trigger that ajax call when something has changed, so i track the onchange event on each textfield to set a flag if something has changed.

The onchange event always fires to first time when i click outside of a textfield even if i didn't change anything in the field.

I narrowed it down to the following: A prefilled textfield always fires the onchange-event the first time you leave the textfield. An initially empty textfield does not fire the onchange event.

Sample code (IE 8 on Windows 7 computer):

script:

HTML:

JQuery :: Text Input Change Event When Value Is Changed By JS

Dec 11, 2011

I've noticed that the change event isn't fired on a text input when it's value is changed by JavaScript. It fires just fine when I type in the input and then lose focus. Example:

$(document).ready(function(){
$("#textinput").change(function(){
alert($(this).val());

[Code].....

I think have JavaScript which changes the value of the input dynamically.

OnChange Event Is Not Working

Jul 23, 2005

In JavaScripts checks for an onChange event against the value of the
textbox at the time of the last onChange event. Since an onChange
Event never fired after you changed the text first time , suppose we
put the same value in the text box then no event is fired.

If we put some other value then it became fired...
It wouldn't fire if we put the same value...

I don't want to use onBlur etc... Isthere any solution with onChange
Event...?

Cancel OnChange Event

Jul 23, 2005

I Have a text box in a jsp that is pre populated. The text box should accept only numbers and it should be greater than a minimum value (this value depends on the user settings). If the user enters a value less than the minimum value, i should pop up an alert saying that the value
entered is incorrect and reset it back to previous correct value. How could i do it using onchange event of the text box.

OnChange Event And Focus()

Jul 23, 2005

Am I right in assuming that you can NOT set focus() back to a field in
its onChange event? Is there another way - I have validation that I
would like to set the focus back to the invalid field onChange?

Eg:
<input type=text" name="tstfld" onChange="window.alert('Changed!');
this.focus()">
