Child Pop Up Race Condition Using Window.open Need To Detect Window.onload
Nov 22, 2011
I am trying to pop up a window and then do stuff(set flags) when the content of the new window is done loading. For this I am trying to detect the window.onload of the pop-up child window but so far I am unsuccessful. I believe my problem is that the URL of child window is on different domain, than the one of the opener(parent) so that the window.onload is not being called. Though this may change, at the moment I do not have access to the code for the page I'm opening up in the pop-up. Im pretty new to web development.

I have a HTML and I am opening another link in a separate window using window.open() . The child window is something like 'http://yahoo.com' which is out side html. I need to refresh the parent window when the child window is closed.

Heres my js code
Code:
//globals
var popupHandle = null;
var openingWindow = false;
function popWindow(URL){
[Code]....
Note: The whole reason why I am doing this is because if its the first time I am clicking on the button that will open this pop up window and I click it repeatedly very quickly, a new pop up is opened for each time I clicked eventhough the window.open is supposed to reuse the window if it has the same windowId. The first call to window.open takes long enough to not have a window handle and allow other clicks to get through.

This is it- when i create the button code with HTML without script language on the page the button works well but when javascript code added is added to the page the button disappears. If i create the button with javascript it appears but does not open the next window.

I've started working with the jQuery UI 1.8 Autcomplete recently with remote data. I was pleased with the ease of initial implementation, but before long I ran into a classic race condition.As I type, the search query gets more specific, so it takes less time for the server respond. As a consequence, it is possible for the old response to arrive after the most recent one. Obviously, this is producing undesirable effects.I'm a little frustrated that the plugin doesn't have a way to manage this. To me, it seems that it makes the "basic" remote data implementation unreliable in most real-world situations. It also seems as though this would be a common problem, but I've found very little literature on it.
I've found that autocomplete is a relatively new addtion to jQuery UI, so I've put the frustration aside and started my own widget which extends autocomplete to solve for three things: 1) race conditions; 2) animated open/close; 3) caching.The nature of this post is two-fold. Not only to share information I've gathered on the topic of race conditions with others who might be having the same trouble, but to (hopefully) gain some insight to how other people are solving for this.The first piece of this puzzle was that $.ajax() (and related methods) return an XMLHTTPRequest instance. As described at stackoverflow.com, this grants us the ability to use XMLHTTPRequest.abort() method. So I just keep a handle to the XMLHTTPRequest instance, and if it exists, call abort() before the next request is made.Using a firebug, I could see that the requests were being aborted as expected and the symptoms of the race-condition ceased. So far, so good... then I got to IE. Not so much.In IE, I was seeing run-time errors. The odd thing is that the run-time errors seemed to be coming from deep within jQuery UI, rather than my code yet commenting out the abort() avoided the run-times. After scratching my head for a while, I used the following simplified code to shed some light on the situation:[code]
In Firefox and Chrome, behavior is as expected - no alert box. However, in IE6 and IE8 (IE7 untested at this time), the success handler still fires! As it turns out, the run-time errors were because the response was undefined as it got passed through my success code path. My next thought was, "maybe I can just evaluate textStatus". Unfortunately, it turns out (as seen in the alert box) it contains the string "success".

I have a parent window that pushes a new window object onto an Array
with the following code :
OpenChild()
{
//totalNumWindowsCreated is global
totalNumWindowsCreated = totalNumWindowsCreated + 1;
childWnds.push(window.open(link, "child" +
totalNumWindowsCreated,"dependent"));
..
..
..
}
This pops up a new window with every call. In the child window I call
a parent function onbeforeunload, appClose() :
function appClose(){
if (window.opener && !window.opener.closed){
window.opener.CloseChild(getQueryString("application"));
}}
This is in my frameset tag of the child code :
<frameset ... onbeforeUnload='appClose()'>
The window.opener.CloseChild() function is called perfectly when I have
one child window open, but as soon as I create another child window
both of the open child windows don't ever call it. They do both go
into the onbeforeunload appClose() function, but do not call the
window.opener.CloseChild() function inside of this routine.
Anyone have any ideas why when I have two child windows open I can't
access the window.opener functions?
I have tried taking each new window out of the array and used the
following code in CloseChild() :
CloseChild()
{
//win and totalNumWindowsCreated are both global
totalNumWindowsCreated = totalNumWindowsCreated + 1;
var win = window.open(link, "child" +
totalNumWindowsCreated,"dependent");
..
..
..
}

How do I force a window, pened alone, to be displayed in its frame set?
tried this:
if (parent.location.href == self.location.href) {
window.location.href = '../'
}
the problem is that the original page is replaced by the main.htm page (the
default page for the 'main' frame)., because the open event of the menu page
calls for the main.htm to be loaded. Is there a way that I could pass a page name as an argument to the index page at all? Something like
window.location.href='index.html?Loc=IT_Study___In formation.htm'

I have a closed box system which opens an html page. The page closes by the
system. I have access to the html page. I added code to open a child window
from this page. However when the parent window closes, the child closes
too. Is there a way to keep the child window open? Yes keep it orphaned.

I'm relatively new to jQ and would like to determine if a named window is already open. If it is then I want to change focus to that window/tab. The scenario is this. I have a link in App1 that opens a new window to an already existing linked (related) web form in App2. If the user forgets they have that window open in App2 and clicks the same link in App1 as before (to open the related form in App2,) it opens a window that is not the same window as the original window. I need App1 to detect if a window already exists in the browser of the same name and if so, change the browser focus to it.

Put a link on my page that will open an external site (over which I have no control) in a pop-up window. When the user closes the pop-up, I want my original page to redirect to another page. The difficulty I'm having is that I can't add any code to the page in the pop-up as it's not my site.

I have created and opened a child window called "checkwin" and have written some data to it. If the data is valid, I want the user to click on the 'CONFIRM' button on the child window, at which time I want the "submit()" function for the form on the parent window to be executed. If the data is invalid the user clicks on 'MODIFY' and I want focus to return to a field on the parent form. However, when I click on the "CONFIRM" or "MODIFY" buttons on the child window, nothing happens. Here is the code:
checkwin.document.write("</td></tr><tr><td align='right'><input type='button' value='CONFIRM'
onclick='opener.document.personnel_form.submit()'></td><td></td><td><input type='button' value='MODIFY'
onclick='opener.document.personnel_form.first_name.focus()'></td></tr></table>")

I'm trying to create code to close the child window I'm creating if the parent window is closed. Here's my code so far:
function openWindow() {
var newWin = window.open(); // open the new window
newWin.document.write('<h1>Child Window</h1>
[Code]...
The above openWindow function is used in this event: <input type="button" name="btn" onclick="openWindow()"value="Open a new window" />
I can generate the new window fine. I just can't close it if the parent window is closed.

I have a parent page which I don't have control of. I call my child page from parent page, perform some operations and once I click update child window should close and parent window should be refreshed.Everything seems to work fine except the parent page not refreshing.I tried using window.opener.location.reload(true). But it makes a postback in the parent page and so the values that I update are lost because it makes a postback with the previous values.I tried window.opener.document.locationwindow.opener.document.location. But this doesn't refresh my parent page.

At the moment, I have a page listing keywords associated with an image. The user can click an 'add keyword' link, which loads a child window where they have a form to select & add extra keywords. Now, at the moment when they submit the form, the page reloads the parent window using an onload event. However, I would prefer it if it only reloaded the DIV which holds their keyword list.
My thinking was I could do it with AJAX or something, but I can't find anywhere that even mentions if it's possible. Can anyone help? Is this possible, or am I too ambitious?
