Capture When A Textbox Has Changed!

Jul 23, 2005

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.

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.

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

[code]....

Button OnClick Event Does Not Work?

Sep 21, 2010

I have identical code in my index that works, so I'm just guessing the error is somewhere else, I know IE is not the best target to aim for - but I really want this to work in the windows default browser....

Here is the php page...
<HTML>
<HEAD>
<TITLE>[code]....
and here is the javascript that works in the index but not here...
function Abort()
{
document.location="AddFamilyMember.php";
};

When I load the page everything looks ok, but click on the abort button, and all that happens is that the little error symbol pops in the lower left of IE. The names of the two files are "AddFamilyMember.php" and "AddFamilyMember.js".

How To Check That A Form Has Been Changed

Apr 30, 2006

How do you detect that a form element has been changed? This thread:

http://groups.google.com/group/comp...25a82c9be127790

suggests that you attach onChange event handlers to every form element,
and when the handler fires you update a global 'isChanged' variable.
This technique seems to be a bit messy to me (I have many form
elements), I was thinking about storing the original form object in a
javascript variable when the body loads (in the bodie's onLoad event
handler), and upons submission, doing a javascript equality comparison
with the current form object. If nothing has changed, then the two
objects should be equal, right?

if(oldObject == document.getElementById('form'))
{
alert('has changed!');
}

Would this work?

Javascript Onclick Event On Submit Button

Oct 6, 2005

I created a "cancel" button for my form at the clients' request, I
accidentally copied a submit button and added an OnClick event- a very
simple javascript.history function. It did not appear to work at all-
it kept submitting the form. I changed the submit button to a plain
old button and it worked fine.

Can anyone explain how the browser works with a javascript onClick
event ona submit button? Does it automatically submit the form no
matter what onClick event you use?

Calling OnClick Event From HTML Form Button?

May 6, 2009

I'm having some issues with my HTML/Javascript page. This is my code:

<script language="JavaScript">

var resposta = form.txtResposta.value;
if (resposta.toUpperCase() == "GOOGLE") {

[Code]....

When I type "google" on txtResposta (text object) and click on btnOK button, the pagina.html page is showed, ok. But if I press the [ENTER] key instead of clicking on btnOK button, the page is reloaded and pagina.html is not showed.

Button OnClick Event Works Great In IE But Not In Safari/FF?

May 14, 2009

I've spend about 2 days writing this javascript code and it works great in IE only to find out that it does nothing in Safari/FF.

Here is my code:

<script type="text/javascript">function calculate() {
var thetotal = 0;
var silver = 0;
var gold = 0;

[Code]....

Basicly what the script does is using some variables in my form will calculate a total price in real time when you click the "Calculate" button. Works great in IE, but in Firefox/Safari it won't do a thing..

Navigate Anchor Links Using A Button Onclick Event?

Feb 18, 2010

I am wondering if it is possible to navigate anchor links using a button onclick event. I want next and previous hit buttons to navigate the already existing hits (#hit1, #hit2, etc.).For instance, I have:

<script type="text/javascript">
var numHits = {HITS}-1;
function nextHit(){[code]....

I have seen working examples with the href tag (e.g. <a href="#" onclick="func();return false">), but nothing with buttons. I also can't seem to get the working href examples to work on my server.For instance, I cannot get this code to work, it just goes to js_required.html:

<a href="js_required.html" onclick="doSomething(); return false;">go</a>
function doSomething(){
alert("test");
}

JQuery :: Accessing Button Attributes OnClick Event Handler

Nov 30, 2011

I am have an MVC app that generates a list of rows, of which one of the columns is a button. Here is the rendered HTML for the buttons:
<input
id
="btnUpdate21"
type
="submit"
value
="Approve"
synchId
="21"
/>
<input
id
="btnUpdate22"
type
="submit"
value
="Approve"
synchId
="22"
/> .....

Following is my selector that I use to bind the buttons to my click event:
<script
type
="text/javascript"
charset
="utf-8"
>
$(document).ready(function
() {
$('input[id^="btnUpdate"]'
).click(promptForSynchDate);
});

I have been trying to access the button Id, though what I really need is the attribute synchId, to use inside of a modal. I have so far been unable to access either one of them. My modal works fine. But the value of either attribute is always "undefined".

Here is my click event handler: (I stuck the alert in there just for debug purposes)
function promptForSynchDate() {
$(document).ready(
function () {
var test1 = $(this).attr('id');
alert(
'test1 is : ' + test1);
$(
'#approve-synch').dialog({ .....

Simple Way To Check If Form Elements Have Changed

Oct 12, 2007

I have a form with many fields... the fields are getting values from a
database.

I've tried onunload to just submit the form regardless of changes or
not but onunload and submit isn't working for me. Now I need some
type of event that will fire when a user tries to navigate from a page
to check to see if anything has changed and if so prompt them
(confirmation) to take action or not.

I know that the reset button only takes away anything that was added
to fields after the load so there must be some way to use the logic of
reset to simply check to see if fields have changed, right?

Onclick Event - Js And ASP.NET - Cancel Button To Prompt The User To Verify Cancellation?

Dec 7, 2009

Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it.

function Clear()
{
var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); [code].....

Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button?

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 :: 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.

Radio Buttons: Preventing The OnClick Event If The Radio Button Is Already Checked

Mar 23, 2009

I have a set of radio buttons each with an onclick event that has a numeric value. When the button is clicked an input box called "Total" is updated with the new value. The problem I'm having is that if a radio button is checked and one clicks on it again then the onclick event is triggered.

Is there any way to prevent the onclick event from triggering if the radio button is already checked?
