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>

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.

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>?

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 :: Change Event Not Firing On Select?

Apr 18, 2011

In IE only, the change event on a select does not seem to fire if the change is made by typing on the keyboard instead of clicking with the mouse. However, when the focus leaves the field, the event fires.

JQuery :: Trigger Click Event On Select?

Jul 15, 2010

I have been trying to develop a simple method of styling the button on select dropdowns. Basically just positioning a span of the button on a select box that is styled as required.

That is trivial...

What I have so far failed to achieve is to get the select box to show its options when clicking this span - just want to have the select box drop down the options as it normally would.

tried .trigger('click') and .trigger('mousedown') but to no avail...

Here is what I have:

$(document).ready(function(){
$('select').after('<span class="cta arrow-down"></span>');
$('input[type="submit"]').after('<span class="cta arrow-right"></span>');
$('span.cta').each(function(){

[Code].....

JQuery :: Change Event On A Select Field When The SelectedIndex Or Val Is Set?

Nov 1, 2010

Is it possible to trigger a change event on a select field when the selectedIndex or val is set with jQuery? I've tried it and it doesn't seem to work. I'm attempting to replace a select field with one of my own design. The issue is if i attached a change event to a select field, when the index is changed it needs to fire that event. Basically if a select field is replaced with my list and a seperate script is set on the select list, I need that seperate script to fire without knowing what it is.

JQuery :: Select A Link Caused By A Click Event?

Mar 29, 2010

i have build a website with google maps. You can find it here: [URL]

Within this website you can search for farmers in Baden-W├╝rttemberg Germany. So if you try to use it for debugging just search for "Stuttgart" f.e.

My problem is that if i click on a marker displayed in the map the associated pagination tab should be opened. I tried to select the link matching the pagination tabs within the Google Gevent.addListener event like: $('a.'+linkid).html('klick mich');

Chaning the html code of the linkid was just for me, so i understand how jQuery works. But how do i implement the function i need?

JQuery :: Why Click Event For Select Option Not Works In IE (8)

Feb 25, 2010

In my form a <select> with options I wrote
$('#select option'). click(function () {
myFunction();
});
Works fine in FF - IE8 works only for
$('#select'). click(function () {
myFunction();
});

But it is not at all the same thing, and myFunction is fired when as soon the select opens. And I want it is fired only when I click on an option (even if it is not a change !) I tried some other manners for the same result. The last one was to write the options as
<options class="opt" value ='x'><option>
and $('.opt').click(function () {
myFunction();
});
Works fine in FF, but not in IE8.

JQuery :: Autocomplete - Using Select Event To Fill Hidden Field

Jul 15, 2010

I'm using jquery autocomplete to fill a textbox with some text but I need to get the ID of the item too. For this purpose I thought to use the on select event to fill an hidden field the problem is that the on select event is never fired.

This is my code
$(function() {
$('input#<%= tblNewInsert.FindControl("nazioni").ClientID %>').autocomplete({
source: function(request, response) {
$.ajax({
url: "offerte.aspx/fillJson",
data: "{ 'descrizione': '" + request.term + "', 'tabella': 'nazioni', 'campo': 'paese' }",
dataType: "json",
type: "POST",
contentType: "application/json; charset=utf-8",
select: function(event, ui) { alert("never fired"},
success: function(data) {
response($.map(data.d, function(item) {
return {
value: item.descrizione
}}))},
error: function(XMLHttpRequest, textStatus, errorThrown) {
alert(textStatus);
}});},
minLength: 1
});});
