hide extjs menu when clicking in different iframe

I have the following problem:
I have an extjs menu in one iframe, and when i click outside this iframe the menu does not collapse, like it does when I click away in the same iframe the menu belongs to.
Do you guys have an idea on how to solve this issue?
This actually happens to any component that should hide when it loses focus. So, I'd love to see a more general solution, if you guys happen to know.
Thanks!
P.S.: I'm using version 3.2

While I don't know if your parent frame is also running a ExtJS application, you are likely going to need to utilize XDM (cross-domain messaging). https://developer.mozilla.org/en-US/docs/Web/API/Window.postMessage
You would then need to add a listener on the parent frame for clicks within the window, and pass that click event to the iframe. The iframe would then handle the click as needed, which in your case is dismissing the menu.

For anyone still looking for a solution on this one.
You can address the Extjs menu and hide all open menus from the parent frame like this (fe inside a click event on the parent):
var menu = window.frames[0].[ExtApplicationName].app.getController('[CONTROLLER]').getMenu().items.items
Next, you can loop through the menu items and hide them by doing:
menu[i].menu.hide();

GWT - how to prevent user from accessing other parts of application when popup is showing

I am rendering a html page that contains a button.
I have bind a method to browser window that opens a gwt popup when the button is invoked.
My problem is, when i scroll the page, the popup stays fixed and the page scrolls. I want the popup to be scrolled along with the html page.
Also, the user should not be allowed to access other parts of app when the popup is open.
Can somebody help me

Assuming you are using the PopupPanel class, it is as easy as calling the right constructor:
PopupPanel(boolean autoHide, boolean modal)
autoHide - true if the popup should be automatically hidden when the user clicks outside of it or the history token changes.
modal - true if keyboard or mouse events that do not target the PopupPanel or its children should be ignored
So if you set the modal parameter, you cannot click outside of the popup, and also the scroll event should not happen at all (that is somewhat right, as scrolling a popup with a fixed positioning doesn't make much sense... Oh well, for a non advertising purpose at least).

Setting focus of a screen reader on a modal alert in ember

I am attempting to make my ember.js app more accessible and am doing my testing via Apple's built-in VoiceOver utility. I'm adding ariaRoles as necessary to my views and tacking on aria-label attributes where the purpose of navigation is unclear. I'm having issues getting the focus on modal alerts, as the reader's focus stays on the page items behind the modal. Does anyone have experience handling focus on modal alerts for screen readers? I'm under the impression that declaring "ariaRole:'alertDialog'" in my view sets the appropriate role for such a dialog, and it is possible that the focus behavior for this role differs between screen readers. Thanks!!!

I don't have first hand experience with modal stuff. Essentially your issue is you are throwing on an ARIA role, and kind of expect it to work. You need to do more than that. You need to keep the following in mind:
Once the link/button is pressed, move focus to the modal window/dialog/popup. Most modal elements are simply a <div>. You can give the<div> an attribute of tabindex="-1".
Trap focus inside the modal window.
Allow the user to press escape to close
When closed, move focus back to link/button

simulate click on a specific place in page

I have a little problem with simulating a click with javascript.
I'm aware of the .click() method but the click must be on a prezi loaded (flash) so don't really have a html element to use.
What I have instead are the exactly coordinates of the place I want to simulate click on. Is there any way I can do that?
The click must activate a flash element. (A play button)
Note: There is a similar question around that have an answer witch require swf control. I don't have that so that method is not applicable.
One other quick question... what happens if I simulate a click on an element that has display: none. It click on the elements "under" it? (as a normal click would do; and yes I know this sounds funny but I don't know how to explain it otherwise). If yes I was thinking of making a position absolute div, put it on top of flash and use .click(). The problem is that i have a feeling that the click won't be applied on flash.
This is somehow a combination of javascript simulate mouse click on specific position and mouse click somewhere else on page (not on a specific div).

Make a transparent gif and position it absolute in your page wherever you need, then simulate a click on it.
I use this technique on some flash ads because I don't want to open links using JavaScript (since some users can be prompted with a question if they wan't or not to open a new page on click).

IE not firing (window|document).onclick event when clicking on a child iFrame

I've got a simple dropdown menu that I want to hide whenever you click anywhere on the page (not on the menu). This works fine in FF and IE until you add iFrames into the page. The menu doesn't hide in IE when you click on the iFrame. Works fine in FireFox.
I tried using document.onclick and window.onclick.
Any ideas?
Edit:
I would prefer not to have to add anything to the iframe. The page is dynamic, and different iframes could be loaded after the menu has already been created. It would be a hassle/undesirable to have to constantly watch for new iFrames and attach events to them.
Yes I am aware of jQuery.live, but we don't use jQuery.
I assume this behaviour is possible since it works on FireFox, I just feel as though I may just be attaching the listener to the wrong event type or the wrong element.

On the parent page, you can search for iFrames in the page and add an onfocus event for them. That event will be fired when the user clicks within the frame.

An alternative would be to have the drop-down menu disappear after a set period of time has elapsed since the mouse or focus was on it rather than requiring a click to dismiss it.

click events bubble up to the owner window and no further. If you want the parent window to find out about clicks on the content inside another frame, you must catch events on its window/document (or have the child document catch clicks and inform its parent document). Yes, it will be a hassle, and jQuery live wouldn't work anyway since it relies on event bubbling.
Alternative approach: when you open a dropdown, also open a transparent ‘shade’ div behind it (but in front of everything else on the page including the iframes), and catch clicks on the shade to close the dropdown.
