Onmouseover And Out Event Bubbling?
Feb 5, 2010
have a small div above (hover) a big one. I assign onmouseover and onmouseout events to the wrapper div. For image caption roll-over animation. The problem is when the mouse is above the caption itself, causing an unwanted result(probably event bubbling).
And another problem: sometimes when you move mouse from outside to container you get a a triple debug sequence: (it should be just 2): -I am over- -I am out- -I am over- (firebug console) How to make it work? (no jquery) must work on all browsers.[URL]... The wanted result: When mouse moved over the image, only mouseover event should be raised once When mouse moved out from the image, only the mouseout event should be raised. when mouse is over the captionm it should be treated as if the mouse is still on the image. (no flickering)

I've been implementing a drop menu in javascript, and I'm finding it difficult to understand why the event bubbling system is implemented as it is. In summary, I want an event to occur when the mouse enters/exits a large div or table that contains many descendent elements.
It appears to me, from experimenting with IE6 and Moz 5, that the event is generated *only* on the lowest element, thus given a table which contains tbody, tr and tds, with an onmouseover listener assigned to the table element (as a property), the onmouseover event is generated only for the td, although the mouse actually entered all these elements.
If there is a slight gap between elements you sometimes get events for the higher element. I guess this is a side-effect of the browser's implementation - sampling the mouse position.
My understanding of event bubbling from "JavaScript the definitive guide" is that events should bubble up the heirarchy unless they are stopped by the stopPropagation() method.

I'm having a problem with .attr(). I will explain it whith code.I have this HTML code:
<p id="textoMarca0" onmouseover="muestraDialog('textoMarca0');">
this is an example paragraph
</p>
[code]....
So now the onmouseover has again its value [the original one, copied by doing an alert($("#"+elem+i).attr('onmouseover')) when i disable the onmouseover event], but it doesn't work

Wanting to have a table cell select it's contained radiobutton in a
rather non-specific way, I wrote the following javascript:
function click_it(element)
{
var x = element.childNodes
for(var i=0;i<x.length;x++)
{
var tag = x[i];
if(!tag.tagName || tag.tagName != "INPUT")
continue;
tag.checked = !tag.checked;
}}
It works fine for clicking the table cell and selecting contained
radiobuttons. However, when actually clicking the radiobutton, the
browser decides (correctly) to first fire the internal radiobutton
click event, thus selecting the radiobutton - and THEN fireing the
click handler for my table cell, thus de-selecting it again :-P If
this was to only work for radiobuttons, I could easily make it do
"tag.checked = 1" every time, but it needs to work for checkboxes too,
so the de-select should work too (if checked).

I am trying to organise some code on a large project I'm doing which changes a lot of code around the page with submit forms. As jQuery doesn't have a live support for submit elements I thought I'd try my hand at event bubbling. It works nicely in firefox but isn't working at all in IE.
[code]
$('#data').submit( function(e) {
/* When a edit form is selected */
if (e.target.className == 'edit_link'){
//ajax request
}});
[/code]
I have a div with an id #data inside this div is a table with data and forms at the end of each of the row to edit parameters. When I click edit it loads a form in another div outside the #data one via ajax then the user can change the values and hit update (which has a class of .edit_link ) at which point it should reload the #data div. The reloading of the #data div is why I need some sort of live event to it. I've tried doing the way above and it works great in firefox but not in IE. Just to clarify the submit doesn't fire at all.

building a tree using UL,LI tags as below. Issue seems with cancelling event bubbling. trying to cancel dragenter event to avoid dragenter firing for root LI. dragenter on image cancels bubbling. But dragenter on the child text bubbles and fires for Root. Whole purpose is to identify LI where its dropped. Edit: Noticed this is working as expected in IE6 and not working with IE8.

I just want to understand the concept of event bubbling, capturing and delegation. I have read a lot about them but still unable to fully understand them (capturing, bubbling, delegation).

I'm in the process of integrating the google maps api into my application. Unfortunately, my events seem to be bubbling. If I open the google maps info window 3 times and click the next button respectively, on the forth time when I click the next button the next event will fire four times. How do I stop this?
$("#google_map_canvas").on("click", "#next", function() {
var toHighlight = $('.first').next().length > 0 ?
$('.first').next() : $('#infoWin li').first();
$(this).fadeOut(100);
$('.first').fadeOut(100);
$('.first').delay(100).removeClass('first');
toHighlight.delay(100).addClass('first');
$('.first').delay(100).fadeIn(100);
$(this).delay(100).fadeIn(100);
});

I have a<button>element inside of which I have 2<span>elements. I have 2 attached jquery click event handlers for each of the span elements so I can do whatever I like for each click. This is all working fine in Chrome and the click event is captured in the correct order: first on any of the span elements and then the event bubbles up to the parent button element. The problem is that in Firefox the click event does not fire for any of the span elements, just the button event handler logs the event as being fired.[URL]..

im having trouble using JQUERYs animate function. Basicly the div has a mouseover event that slides another div (that is inside the original div) upwards. The first div has a mouseout event that slides the second div downwards and out of view. The problem being that when you hover over the second div it fires the first divs mouseout event. Ive tried googling this and have tried adding some event bubbling but having serious trouble with it. here is the website... [URL] hover over the image and you should see the caption appear, roll over the caption and it goes crazy.

I have a table with two columns and two rows in it. In the upper left corner, I
have a logo image for my company. In the top right column/cell, I have some
navigational stuff, no big deal. In the left cell in the 2nd row, I have a list
of anchors of different songs I am producing - something like this:
<A HREF="jamison.mp3">Jamison</A>
<A HREF="tlw.mp3">The Long Winter</A>
<A HREF="summer.mp3">It's Summertime</A>
....
....
The cell on the right, 2nd row is empty at the start.
On the 2nd row, 1st cell, where the anchors are, on a "mouse over" event, I'd
like to display song lyrics and information regarding the song in the right
cell, 2nd row as the user moves the mouse over a given anchor.
What is the best way for me to do this? There are a couple of things/issues I
can think of right away:
1) Let's say there are 20 anchors in the left column. Let's say that some of
the songs' lyrics are quite lengthy and extend past the height of the cell at
row 2, left column. How would the system know this in advance (this will make
more sense with question #2 below)? Perhaps tell it some type of maximum height
you know will never be reached or something?
2) To me it doesn't make a lot of sense to include all this text in the main
HTML file since a majority of the time, the user(s) will never move their mouse
across ALL the anchors, only one or two. Seems to me there should be some way
of "loading" them as soon as the mouse over event occurs.

How to disable onmouseover event in onclick event using java script

I have written some dom code to create a list of divs, each with it's
own id. I want to set the onmouseover and onmouseout events to
highlight the div when the mouse is over it. However I cannot use the
method below because oDiv.id is always set to the last div I create -
so the last div is highlighted regardless of which div I am onmouseover
This must be a common issue, how do I go about fixing it?
I can have a separate function which takes event.srcElement and tracks
back through the parent elments until it finds a div with an id
starting with "entry_" but I was hoping for an easier option.
Is this something to do with closures?
Here's a much simplified example :
for( nIndex=0; nIndex<aEntries.length; nIndex++)
{
oEntry = aEntries[nIndex];
oDiv = document.createElement( "div");
oDiv.id = "entry_" + oEntry.uniquename;
oDiv. {document.getElementById(
oDiv.id).className = "hover";};
oDiv. {document.getElementById(
oDiv.id).className = "";};
oBody.appendChild( oDiv)
}

I hope this is relatively simple. I've looked around for the answer, but I thin think the search terms (update onchange event) are a bit too common...
document.getElementById("tester").innerHTML= "hello";
document.getElementById("tester").onmouseover = "alert('hello')";
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything.

Basically I have site that uses iframes to load its content. In one of the frames I have an html page that contains an image, and when you mouse over the image it is supposed to fade up a little description box. Naturally when you move the mouse away, the box disappears. I have a javascript function that fades the image up and down, and it's activated via an onmouseover event that is attached to a div that contains no content, but lays over the image to define the triggering area.
I use Dreamweaver to preview my pages while they are stored on my computer, and everything works beautifully. However, once I upload the page to my site, that functionality disappears completely. Code:

I have a list of links to PDF articles, each link has a corresponding div that contains an introduction to the article. I'm using the onmouseover event in each link to show the corresponding introduction div and hide all the others.
The order and number of the pdf links and the introductory divs are the same. The code below works in IE but not in FireFox - the problem in FF is the index returned from the onmouseover event is double what it should be, so the first PDF link shows the second div, the second PDF link shows the fourth div ect.

I'm looking for a jQuery plugin, which could create a flyout of a container from left or right side of a page on some event (onClick or onMouseOver).
The example can be found at [URL] when the page loads some shopping ads slide from the left side of the browser screen (it's shown automatically only once, to see it again you need to delete this website cookies and reload the page - it would be great if the plugin had this cookie-based feature).

I have a div called 'options' which contains another called 'settings'. I want 'settings' to have a left border when the mouse is over 'options', but not when it's over 'settings'. I tried the code below but the style isn't being overwritten by the second onmouseover function.
function sett() {
var o = document.getElementById('options');
var s = document.getElementById('settings');
if (o && s) {
o.onmouseover = function() {
s.style.borderLeft = Ƈpx solid #88B216'
}
o.onmouseout = function() {
s.removeAttribute('style');
}
s.onmouseover = function() {
s.className = 'settingsactive'
s.style.borderLeft = 'none'
}
s.onmouseout = function() {
s.removeAttribute('className');
} }}
What can I do?

At work I have written a form builder which is all drag and drop.
The issue I have is with ending the drop, I have no problems in IE. The drag is controlled by the onmousemove and onmouseup events for the document body.
The trouble is, in Firefox, if the cursor is over a form item, then the onmouseup event doesn't fire and therefore the drag doesn't end.
There is no problem with other items, other HTML items, tables, list, divs, then all bubble the event to the body.
Anyone ever come across this, if so how did you get round it.
Do I need to manually make form elements bubble in Firefox? Maybe I should just stick a div opacity 0 over the drag objects and make that call the body's onmouseup event.

The objective is to create a stacked, inline vertical menu. Upon mousing over a menu option, a series of sublinks (children) presents itself immediately beneath the parent. The children push the rest of the menu options downward. We're ok up to this point.
Should the mouse pointer point to another menu option, the children of the former menu option pointed at disappear and the new children are displayed. We're still ok. Here's the code I use to accomplish this: Code:
