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.

Code JavaScript:
$(document).ready(function(){
$("#generate_name").change(function(){

I have an object that has a click event I'm trying to trigger. However in the click event I have the following if statement:
if(event.button != 0){return true;}
This if statement allows right clicks to go through and activate but it also prevents me from triggering the event. Any ideas on how to prevent this? If I remove the if statement from the first click function everything works as intended.Here's my example code based off of the trigger event examples:
<!DOCTYPE html>
<html>
<head>

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.

I've created a checkbox and radio button replacement plugin (URL...), and I'm trying to be as thorough as possible.One situation that I have yet to solve is if a button is given the attribute checked="checked" through some external function. I'm not sure of how to detect this event so that the replacement image is also updated. The .change() method only works when the user actually clicks on the button.The reason I am trying to work this out is because I am adding support for disabled buttons as well. From what I've seen, there are plenty of situations where a button is disabled until a user either selects something else, or fills in required info, etc., and then it is enabled (most likely through the removal of disabled= 'disabled '). If the developer has already worked that in, I don't want the implementation of my plugin to affect that. It should just work automatically.I do check the states on page load, but i'm not running any sort of loop to constantly look for changes.

I have some simple code to make a link open on page load. When the code fires it shows the alert 'clicked' but then nothing happens. The url is generated with APEX and if i click the link on the page physically the alert fires and the page redirects to the linked Url. Why isn't the click event working?
jQuery:
$(document).ready(function(){
$('.myLink').click();
});[code]....

I built a small JavaScript file that does some HTML and CSS manipulation when you hover over any tag with a certain class. It works great when running on the same server, but if I try to use the JS as an external script, the hover event isn't triggering. Here is my external JS file code:
$(document).ready(function() {
alert('i work inside');
$(".start").hover(
function (e) {

I have a function where I want to add a sibling element to each of the elements and trigger a click on each of them right away. Here's what I have so far:
$(function(){
$('#articles').delegate('.click-link','click',function(){
$(this).toggle(
function(){
alert('toggle one');
},
function(){
alert('toggle two');
});
});
$('.toggle').each(function(){
$(this).after('<span class="click-link">Hide</span>');
$(this).next().trigger('click');
});
});
For some reason the toggle doesn't get triggered. If I put something in the function right before the toggle, it fires on page ready. However, the toggle doesn't fire. toggleClass does, though. What can be causing this?

I've been using this little bit of code to show a div when the user rolls over a link:
$('a#eventspopupbtn').mouseover(function() {$('#menu').hide('fast'); $('#eventspopup').show('fast');
return false;
});
I have been trying to extend this bit of code so that there is a short delay built inso that if the user rolls over the link by mistake or 'just passing through' the div is not displayed. I tried using setTimeout but couldn't get that working (unfortunately, I can't share that with you because I lost the code).

I'm new to jquery, and to javascript in fact. I'm trying to find some way to find out when an element (by its Id, class or element type) has been loaded. What I have is the following: I have a report in a table, and the records are paginated so that only a few (say 10) are shown each time. When I press "next page" only the table is reloaded instead of the whole page.
The thing is, some of the table cells have a datepicker, but I only manage to show the datepicker in the first page (because it is the only time when the whole page is loaded and I add the datepicker on document.ready). So, I guess what I'm looking for is something like $("table").ready(function... . I have found an "elementReady" plugin, but what it does is triggering an event when a given element is ready (which is what I want) only when the full DOM is loading (which is not what I want).

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.

I want an event to be triggered when I use left and right arrow buttons like this:
Code:
$(document).keypress(function(e){
if (e.keyCode == 39 && key_pressOK) {
e.preventDefault();
$("#next").trigger('click');
key_pressOK = 0;
}});
This works on firefox, but not chrome, haven't even bothered checking the other browsers since it didn't even work on chrome.

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?

I am working on a page that will load in other pages using AJAX and the .html method. Something like this :
<span id = "edit">Edit</span>
<div id = "cont">
</div>
//the click edit script
[Code]....
Unfortunately this does not seem to work, entirely. It does trigger the click event but it messes up the post for some reason. I have played around with it for the last 45 minutes or so and it seems like the click event trigger is what is messing things up, if I comment it out it works fine. Could anyone tell me why they think this is? note this is an over simplified version of my actual code, but the structure is the same.

I've been stuck on this for a few hours today, and I can't seem to figure out how to correctly accomplish my task.Objective: Dynamically change the value of a <input type="checkbox" />, thus causing the .change( ) event to be fired, from an outside element, with the checkbox being hidden.So, my code eventually gets to this point:
if ( /* CONDITION */ )
{
$( 'input[name="new"]' ).attr( 'checked', true );
[code]....

I'm trying to add a function to an event click from a checkbox. But the function is executed on the page load, not when i click on a checkbox...
Here is my code :
var tabTailles = {
"38092":{"id":38092,"qte":8,"produitsIds":[293649,293653,293655,293656]},
"38093":{"id":38093,"qte":20,"produitsIds":[293649,293653,293655,293656]}
}
[code]....
tabTailles is an array but not a js array. val is an object.
