Currently I use an onbeforeunload method, to do call various tidy up
methods when a user exits my web application - however I now need to add
additional support, for users migrating to Sun's JVM.
My understanding that the onbeforeunload call is a Microsoft one, and
the net result of having it in a page used by a SUN JVM user is that the
browser does not close.
Does anyone know of an alternative to this method, that is supported
by Sun's JVM?
The onbeforeunload fires just before the current document begins to
unload due to form submission or window closure.
How can I have this code run after window closure (X) but not after
pressing a button (form submission)?
I want to override the onbeforeunload event so that when the user
clicks on the close button, at the right top of the screen, it only
open an alert with OK button and don't close the screen ...
the bug of onbeforeunload is so obvious!
in IE 6 it will popup twice "sometimes"
I am using the following code
window.onbeforeunload = null;
window.onbeforeunload = confirmExit;
var executingPostBack = false;
function confirmExit()
{
if ( typeof executingPostBack != 'undefined' && !executingPostBack)
{
return 'Warning: Modified data has not been saved.' ;
}
}
In some cases, IE pops up it twice, for example, when we click a link
that contains "__doPostBack", onbeforeunload is fired the first time;
when the form is submitted, it is fired second time.
There is no way to work it around, because onbeforeunload is stupid, we
can't know whether the user clicks OK or Cancel.
I would like to use the following code with confirm so that I know
exactly what the user behaves
res = confirm("leaving?");
if (res==1)
{
alert("yes");
}
else
{
alert("no");
}
but I can't use this in onbeforeunload, because I can't stop it!
onbeforeunload always asks for something return, but if I return
anything, it will popup!
I have written a web application in .ASP with VBScript and JavaScript running against a SQL back end. Everything works great except my BeforeUnload() event:
<%'Add a script to save any unsaved data before the client leaves the page%>
<script language="JavaScript">
window.
function confirmExit()
{if (document.Client_Info_Page.Value_Changed.value == "true")
{if (confirm("This record has been changed. Press [OK] to save; [Cancel] to discard."))
{document.Client_Info_Page.submit();
alert("Changed and save");}
else
{alert("Changed and no save");}
}
}
</script>
<%'END Add a script to save any unsaved data before the client leaves the page%>
This code checks a variable to see if anything's been changed on the page and if it has, it asks the user if they'd like to save before exiting. The alert boxes are just to show the If/Then is working correctly (which it is) but the .Submit() function just gets ignored as the page exits.
Just to play, I made a java button and cut and pasted the submit() into and when that's clicked it submits with no problem.
Anyone know how I can get the onBeforeUnload to push a .Submit()? I've changed it to stop the exit and allow the user to save, but it would be so much smoother if it could be automatic.
Can 'onbeforeunload' (ie) be used to trigger a javascript? I can't find any info on how or if this is possible.

1. "Are you sure you want to navigate away from this page?"
2. "Press OK to continue, or Cancel to stay on current page"
I need to provide the user a custome message. I tried many approachs, but non of them seem to work. I tried to use a confirm box instead, but for some reason, the return value for onBeforeUnload event seem to be used as string, so return false to the event CANNOT stop the page from refreshing.
I set some value like in onbeforeUnload
document.getElementById('hGridStateModified').value='YES';
The value is not set and is not available at server side.

View 3 Replies View RelatedI'm trying to add the "you have unsaved changes" message to a form. I have it working in every browser except IE7 and IE8.I have set the onbeforeunload with using a global "goodExit" variable (that's supposed to help IE, and it did partially).The thing is, that I have multiple tabs on the page, so I only show part of the form at any given time. If they change a field on one tab, the top of the page shows a visual box of "unsaved data", so that as the users changes tabs the box at the top still shows.The problem is that, IE fires the onbeforeunload anytime someone clicks to change tabs. The only thing that happens when they click a tab is that I use jQuery to show/hide the DIVs appropriately.Why does IE fire onbeforeunload when changing the display of DIVs???!!!No other browser does this.The global "goodExit" variable meant to help IE, seems to work, except that goodExit is set to true if they change any field on a tab, so that then the next tab they switch to fires the event.

So, does anyone know better alternative for RSH?
In my webpage I have an embedded Windows Media Player and an unordered
list with a table of contents.
When playing a video, the Windows Media Player is triggering events for
new 'chapters'.
The corresponding chapter in the unordered list is then highlighted
with css.
The list can contain up tot 100+ items. Because the page itself should
fit the screen without scrolling, i put the list in a scrolling div.
I also want the div to scroll automatically in order to keep the
current chapter inside the visible scope of the div.
Right now i do this by initually creating an anchor for each listitem.
When an chapterswitch event occurs i scroll to the corresponding
chapter with the folling line of Javascript code:
window.location = "#" + ListItemId;
There is one problem; the annoying tick sounds in IE. For my
application it is not rare to have 25 'chapters' switched in one
minute, so that's an awful lot of ticking.
I was wondering if it is possible to automatically scroll up or down to
a specific point in a div without the browser making any sounds.
I was wondering if anyone can help me? I am having some problems wit
the <noscript> tag.
I actually use it to block banner advertisements from being displaye
in my website. I have used it at the <body> tag section and look
something like this:
<noscript>
<body>
</noscript>
What it does is stop the banner advertisement offered in most fre
websites from loading.
My question is how come it does not stop the banner from loading if
was to view the webpage in my Pocket PC using Pocket Internet Explore
Pocket IE)?
Everytime I load the page in Pocket IE, it displays a standard banne
that is found in all pages viewed using Pocket IE. I looked around fo
some answers and I found out that Pocket IE found in the Pocket PC 200
does not support the <noscript> tag.
Is there another way around this? I have written some pages that wil
load in my Pocket PC and I find it very annoying to see the banne
advertisement at the top. Code:
Is there an other way to link to an element on the same page without using anchor URLs?
View 18 Replies View RelatedI was wondering if there was an addLoadEvent alternative, that could be used before all images are loaded? I think it's something like when the DOM is ready...
View 1 Replies View Relatedthis is the code I'm working on:
Code:
var tabs = new Control.Tabs('menu');
var pattern = 'tab=';
var nStr = location.href;
if(nStr.match(new RegExp (pattern,'gi'))){
var id = nStr.split(pattern);
[Code]...
It searches for the query string 'tabs=' and then splits the result to get the id of the tab. Then it uses this to set the active tab. If the url doesn't include the query string it set the tab to the first one.
The code works but it uses Eval to convert the id string (id[1]) to a variable and I was wondering if there was an alternative.
Is it possible to capture the control.event or element.event that was fired to invoke the onbeforeunload event.
For example, if a button is clicked and it causes the onbeforeunload event to fire can i determine which button was clicked.
On my site I use "window.onbeforeunload" to give a confirmation that the user wants to leave the site when they're doing something which will be interrupted by leaving the site. The problem is that when a user requests a certain file to download, I use "window.location" to point to the PHP script which in-turn starts the file download. Now, the user's browser never actually changes pages, but because I'm launching the download through "window.location" it's triggering the "window.onbeforeunload". Is there any way that I can detect that I'm requesting the download (like matching the script name in the target url?) and then not show the leaving confirmation?
View 2 Replies View RelatedIs there a more concise way to do something like the the
desired code below?
The gripe is with the try-catch syntax. It takes *way* too
many lines of code to evaluate a conditional expression
when zero or more parts of the conditional expression may
trigger an error. In this case, the trigger is a call to
a non-defined (null) object.
In other words, how can you do a more simple 'try' statement
that simply spits out true or false, depending on whether
the 'tried' code threw an error or not?
Defining a function don't seem to work because you
can't pass the 'try' code as an argument. Extending the
'Global' constructor is not an option, so now what? Code:
Is there a possibility to do a string replace in javascript without regular experessions. It feels like using a hammer to crash an egg.
View 24 Replies View RelatedI'm working on integrating the a javascript wysiwyg editor (Xinha) with
my blog software (ExpressionEngine, aka EE). EE has extensions now so
it's easy to get the Xinha header code into the head section of the EE
web page.
But Xinha likes to use an onload command to launch:
window.onload = xinha_init;
....and EE is already using the onload command in the body tag of the web
page:
<body onLoad="document.forms[0].title.focus();set_catlink();" >
The onload command in the body tag is keeping the window.onload command
from working. At this point EE doesn't let extensions modify the body
tag.
Is there an alternative way to run the xinha_init command, without using
the window.onload command?

I want to use an anchor tag to invoke some javascript and I've read that it's bad form to use <a href="javascript:foo()">
I've read endless usenet posts and hint sites on the net, they all suggest different things and I can't get any kind of consistency, and I can't find any solution that works properly for IE, opera and mozilla.
many of the recommended solutions go something like this:
<a href="javascript:void(0);" onclick="foo()" />
this generates an <a> that looks like a hyperlink (good) and it invokes foo() as well (also good). the problem is that if in function foo, I put
window.location.href = "some new url";
it just seems to get ignored. If I miss out the href altogether, the link works but it's not formatted as a hyperlink.
All I'm trying to do is make something that looks like a normal hyperlink but whereby I can build the URL with some javascript rather than having it coded into the HTML, and I have to say it's driving me mad!!.
I'm looking for an alternative for .closest(). My script refers to jQuery 1.3.2 which is not the latest, but does its job. By trying to implement my code into another script I noticed that this script uses jQuery 1.2.6. Well, 'changing that version was no option'.[code]This is my code. It should be used to clone special comments containing "In[" and in some cases "text".Unfortunately .closest() doesn't work out for me. i'm looking for an alternative.
