Determine Which Control In Window.onbeforeunload In Javascript Caused Event

Mar 7, 2011

I have set up in javascript:

var onBeforeUnloadFired = false;
window.onbeforeunload = function (sender, args)
{
if(window.event){
if(!onBeforeUnloadFired) {
onBeforeUnloadFired = true;
window.event.returnValue = 'You will lose any unsaved changes!'; //IE
}
}
else {
return 'You will lose any unsaved changes!'; //FX
}
windows.setTimeout("ResetOnBeforeUnloadFired()", 1000);
}
function ResetOnBeforeUnloadFired() {
//Need this variable to prevent IE firing twice.
onBeforeUnloadFired = false;
}

I'm trying to achieve an edit screen where the user is warned before navigating away. It works fine except I get the pop up for normal post backs of button clicks. I'm hoping to avoid this so I'm figuring if I could determine which button was pressed it would work. Does anybody know how to determine which button was pressed in the indows.onbeforeunload? Alternatively anyone know a better approach to what I'm trying to achieve?

Javascript - OnBeforeUnload - How To Call A Server-side Function Without Ajax

Jul 22, 2010

What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)

Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.

Javascript - Chrome/Safari Not Calling Unload In Some Cases?

Feb 26, 2011

Have been stuck with this issue for a few days now, and really need, and would appreciate some help. My requirement is that I want to make a server side callback to clear off some objects when the user navigates away from our page, without clicking logout. For business reasons, our ASP.NET session timeout has to be set to a very high value. Further, I do not want to popup a alert/dialog to force the user to return to the page and click Logoff.The solution I have arrived at thus far is to make a AJAX callback by embedding this javascript in the page.

window.onunload = pageleave;
function pageleave() {
alert('test');

Web Forms :: Response Is Not Available In This Context During Page Unload?

Feb 7, 2011

When my asp.net aspx page unloads i am trying to check if the current session is expired. I have this code in the Page_unlaod and i get a "Response is not available in this context" error. What is the problem placing this code in the Page_unlaod?

[Code]....

the page is in a frame with 3 other pages so when the page is doing a postback, there is client side code that will the page 2 in the frameset to 100% visible, then when page is laoded and the document is ready it sets itself 100% visible in the frame. I have tried placing the code in page_load but when the session has timedout the pageload is never executed again. I have tried to place the code in the pageload of page 2 in the frameset but that causes some funny behavior and unwanted redirects.

Master Page And JavaScript / Command Can Not Send Any Value From New Window To Parent?

Dec 1, 2010

I prepared an aspx file that can open a new window with (window.open) command. In the child window, some values send to parent page with (.innerHTML) command and it can close itself . However, after I set a master page to parent page , command can not send any value from new window to parent and it can not close itself.

How master page can affect my javascript commands?

Javascript - Passing Data Between A Parent Window And A Child Popup Window With JQuery

Dec 3, 2010

I have the following HTML

<tr>
<td class="label" valign="top">
Affiliate Party
</td>
<td class="field">
<input type="hidden" name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyId" id="AffiliatePartyId" />
<input name="ctl00$MainContent$ExternalAccountAttributes$AffiliatePartyName" type="text" id="AffiliatePartyName" class="PartyLookup" />
</td>
</tr>

and the following Javascript/jQuery

$(".PartyLookup").after("<img src='Images/book_open.png' class='PartyLookupToggle' style='padding-left:4px;' />");
$(".PartyLookupToggle").click(function () {
window.open("PartySearch.aspx", "PartySearch", "width=400,height=50");
return false;
});

I need to be able to flag ANY PartyId input field with class="PartyLookup" so that it will modify the DOM and include the image next to the input field. The popup window returns data to populate both the hidden and text fields, but since the click() is generic I need to pass it the ID of the input field.

Javascript - Session Null After Window Open In Minimal SharePoint Page

Apr 4, 2011

I'm storing a token in a session variable. I launch a report that needs this token in a new ASPX page by using the javascript windows.open function. When this new page loads the HttpContext.Current.Session is null.I have gotten around this by passing the token in the query string but activity in this window needs to keep the session of the parent window active and I'm not sure what the session object being null means for this scenario.

Javascript - Reporting Child Window's Events To Parent Window To Reset Timer Value Of User Timeout Code

Sep 2, 2010

I've got a Jquery function that I wrote which blacks out the screen after a certain amount of inactivity, creates a pop-up that allows the user to click a button to stay logged in, and logs them out (closing the application window) if they do not respond in time.

The environment is ASP.NET (VB). We don't technically use master pages, but we do have a parent page in which our header, footer and nav reside, and my Jquery code is called from that window, loaded via an IFrame.My problem is that if one is working in a child window, the parent window doesn't recognize that the system is in use, and will automatically engage at the allocated time.I've tried everything under the sun I can think of and nothing works properly. My event handler is working, and it does call the parent window function, but the timer is not being reset.

I have this function in the parent window:

<script language="javascript" type="text/javascript">
function window.reportChildActivity() {
SESSION_ALIVE = true; [code]....

Javascript - IE - Get Popup's Opening Window When Using Window.open (url)?

Sep 23, 2010

we are running a click-to-call service, my idea is basically like this: website have a link on their page, when the link is clicked, a web page(say it is popup.aspx) hosted on our server is popup, user can input their phone number, and click "call me" button to let the website call him. In the button click event, I want to get Request.UrlReferrer, then query the db to get website's phone. But in IE, Request.UrlReferrer is null(firefox is ok, not test chrome yet),my question is how to get opening window' url in IE? we put popup.aspx on our server because

our client website is not force to use asp.net. we have the control what we put on the popup window, and can modify the page just from our side, if we put the pop window on our partner's side, if we have 100 partner, and we change the page's design, we will notify everyone of them to change this, change that. we can implement a statics system to know how popup a day, which site is most popular,etc

Javascript - .NET Cross Domain Modal Window (window.showModalDialog) - Parameter Value Always "undefined"?

Aug 27, 2010

I have two webpages, parent page .aspx and child page .html.
On parent page I have JavaScript function for invoking child page as modal window via window.showModalDialog.

function viewCourseModal(url) {

var sPars = SomeParameters();
var returnedValue = window.showModalDialog(url, "", sPars);[CODE]...

So when I launch parent window and invoke child modal window, parameter with "someValue" gets returned to the parent window (to modalReadyForTest control) upon clicking the button Button1.It works fine when I have both parent and child pages on the same domain. When I have them on different domains, value of the parameters does not get passed and instead it is always "undefined".Is there any way to have modal window from different domain returning parameter value to parent page? Can those cross domain issues be solved at all or should I try completely different approach?
