mouseover, mouseout not working well across windows

This problem is a little complicated and wordy.
I have a parent window, which pops out a child window. They have some overlapping area.
In parent window, there is a div which handles mouseover and mouseout event.
When the child window pops out, it covers part of the parent div.
In the following, mouse moves to div (mouseover works), click pops out child window.
Now move mouse to child window. At this moment, I expect mouseout to div, but not.
I guess the system still thinks the mouse is within div even covered by the child window.
Is there any way to get through this? But the relative position of those elements should not change. Thank you for your advice.

If all else fails move your code from the mouseout event of the div to the mouseover event of the pop-up. First, though, I'd make sure that the mouseout event ever fires, e.g. when you move outside the div's bounds.

javascript: unintentional feedback loop

I am trying to create an animation in javascript that is triggered by a mouseover event and then returns to the initial state on mouse out. When the user runs their cursor over an image on the page, another div with an initial height of 0px gradually rises in height to 50px over the bottom portion of the image.
The problem I am facing is that when they move the cursor from the image to the div which now covers the bottom portion of the image, it triggers the mouseout (as it is a separate element from the image) and then a new mouseover event in quick succession because the div disappears when it detects that the cursor is no longer over the image (meaning the div appears and disappears quickly, over and over again).
I am wondering how I would go about breaking such a loop so that the div does not disappear when the cursor runs over it from the image (i.e. prevent the onmouseout event from triggering unless the mouse moves to some other element that is not the newly created div).
Here's an image to hopefully better illustrate the problem:

I think for this situation you'd want to use a wrapper div around both the image and the div you're animating. Attach the mouseover/mouseout events to the wrapper and they will trigger when you're expecting them to. Here's a jsfiddle example

OnMouseOver DIV trouble

Ok so my basic problem is as follows. I have an image that causes everything else on the page disable using a blank div with a z-index. This is during a mouseover event of the image. Next the code goes into setting the z-index on the div that I want to be able to click or mouseover. Also I wrapping these images in a div that is used for a mouseout event to hide the images I do not want to show.
However when mousing over the images or text inside the div it causes the mouseout event to trigger. I have looked into event bubbling but it does not seem to be what is happening. Is there a way to turn off the mouseout event to object inside of the div with the mouseover event?
Long story short I need to make a mouseout event not trigger on nested items.
Thanks in advance.

Instead of using mouseout you may go this way:
when blocking the UI by overlaying the page with the blank div observe the mouseover-event of the wrapper-div
When mouseover fires on the wrapper-div start observing the mouseover-event of the blank div
When the mouseover fires on the blank div reset the page(remove the blank div)
The approach should be clear, if the mouse is over the blank div it must be outside the wrapper-div.

What mouse/touch events should I use to cause a div to change color when cursor is dragged over it?

I'd like to know what mouse events I need to use for the task below.
When a cursor is dragged over a div, the div changes color.
By dragged I mean that the mouse button has been clicked once (and not released) somewhere outside the div and then the cursor has been moved over the div (the mouse button has not been released at any time during this process).
The div shouldn't respond to onmouseover. The mouse button needs to have been depressed and then dragged over the div to activate the change in the div.
I'm also wondering if there are any equivalent events for touch devices?

If i understand this right you can do the following:
set a global variable "mousedown" to false
use the "onmousedown" event to set "mousedown" to true
use the "onmouseover" event of your div to fire a function where you first check if mousedown is true and if so make the div visible
use the "onmouseup" event on your page to set "mousedown" to false again
For anything javascript related to touch event you should have a look at Sencha Touch
EDIT: If you want to avoid such frameworks. You should have a look at The HTML5 Specification. There are a couple of new events related to touch devices.
Here is a nice article about it:
http://www.html5rocks.com/en/mobile/touch.html

I'd recommend JQueryUI for this - it has several drag-specific events built-in. The drag event for touch devices is called touchmove

Difference between onMouseOver and onMouseEnter

I'm trying to have a simple html table, that highlights a row as a user mouses over it. Unfortunately the css hover item doesn't work for IE. That leaves me to simulate it in Javascript. I can use either onmouseenter or onmouseover.
What is the difference between them, and which one should I use?

Both onmouseenter and onmouseover fire when the mouse enters the boundary of an element. However, onmouseenter doesn't fire again (does not bubble) if the mouse enters a child element within this first element.

Unlike the onmouseover event, the onmouseenter event does not bubble. In other words, the onmouseenter event does not fire when the user moves the mouse pointer over elements contained by the object, whereas onmouseover does fire.
I always use onmouseover. I use onmouseover in the same purpose (highlights a row).

You might spare yourself some coding by just adding :hover support for all elements in IE too:
