Window Open & Close

**gits** · Jan 29 '08, 07:07 AM

hi ...

the following check should work for your function:

[CODE=javascript]if (typeof my_window != 'undefined' && !my_window.clos ed) {
alert('Close the window!');
} else {
alert('Window already closed!');
}
[/CODE]
kind regards

then adapt the call too and use the onclick instead of href:

[HTML]<a href="#" onclick="TestPo pUp('your_href' );">txt</a>[/HTML]
kind regards

Hi ,
I have changed the code and added onclick ="fun(..)".
But the problem is not solved as it every time executing the else part.

Here is the code that I am using.:

[CODE=javascript]<script type ="text/javascript" language ="javascript " >
var my_window =null;
function ClosePopup()
{
if(typeof my_window!='und efined' && !my_window.clos ed)
{
alert('Close the window!');

}
else
{
alert('Window already closed!');
}
}

function TestPopUp(My_Hr ef)
{
my_window = window.open(My_ Href, "mywindow","sta tus=1");
}
</script>[/CODE]
my_window is global variable.

when i simply test that code in FF it works without problems ... please post the page where you call that code ... is something reloaded elsewhere during the operation?

kind regards

ps: sorry i missed that you posted your code and the var declaration already in the original post so that i should have seen that your var is global :)

hi ...

i'm not very familiar with asp ... but it should work with any window that you open by a javascript window.open() ... could you please send the source view as it turns out in the browser, i mean the rendered page? ... so i could test it here locally?

kind regards

hi ...

thank you ... i could only discover one error, since my_window is initialized with null we have to check for that accordingly:

[CODE=javascript]if (my_window != null && !my_window.clos ed) {
// code goes here
}[/CODE]
the 'View Status' action works as intended i think ... and gives the correct message with your posted code ... i opened one window and i closed it ... both times it worked correct ... could you tell with which test the error occurs?

kind regards

**gyanendar** · Jan 30 '08, 07:45 AM

Hi,
Here my requirement is that , I have to get the status of opened window at any point of time(i.e. I have to get the wether the window is open or close.)
With this code I am able to open file in new window.But at any point of time I am not able to find the status of newly opned window(wether it is still open or closed).
The code segement
[CODE=javascript]function ClosePopup()
{
if(my_window!=n ull && !my_window.clos ed)
{
alert('Close the window!');
}
else
{
alert('Window already closed!');
}
}[/CODE]
always executing else part.
It means !my_window.clos ed part always returning true irrespective of state of the newly opened window.
This is the main problem I am facing.

Other problem is
I have added one link to close the opend window from parant window
[HTML] <a href ="Javascript:my _window.close() ;">Close it</a>[/HTML]
But whenever I am clicking this link it showing Javascript error (Permission denied)when child window is open.
If I close the child window than it not showing anything(no error).

Regards,
Manohar

**gits** · Jan 30 '08, 08:52 AM

as i said ... the page works locally without problems ... is there a postback or something like that when you click the links? i could not reproduce the error ...

1. i open a new window
2. view state alerts -> close this window
3. close the window
4. view state alerts -> window is closed aready

-> so it works ... now when there is a 'silent' pagereload the my_window-variable will be set to null again ... and we loose the reference to the opened window. could this be the case? put an:

[CODE=javascript]alert(my_window ); [/CODE]
at top of the ClosePopup() function. what does it alert?

kind regards
