Close one window from another window.

djunaedwards · May 5, 2004

I program mostly in ColdFusion and don't use JavaScript a lot. Could someone help me with this?

I have a timer window that executes while a query is running. When the window that displays the query results loads, I want to close the timer window. This close needs to occur automatically from the query results window.
The timer window is invoked by
window.open("ka.cfm", "ka",...)
I have tried invoking ka.close() on the query results window, but get js error "'ka' is undefined".

Thanks

Create a global javascript variable (inside the <SCRIPT> tags, but outside of any function) called (for example): newWin;

Then, when you do the window.open(...) command, set the return value to newWin. For example:

newWin = window.open(...);

Then, when you want, you can:

newWin.close();

Thanks for responding.
That does not seem to work in this case.
The sequence of events is:

1) User inputs query on first screen.
2) A submit button submits the form with the query to
the query results page.
3) This submit button also triggers a timer window that
does some other things in the background.
4) When the query results page loads, I need it to
close the timer window.

Thanks,
Djuna

In parent (pseudo-code):

Code:

var newWin, timerWindow;
function onClickOfSubmitButton()
{
 newWin = window.open(1st window);
 timerWindow = window.open(2nd window);
}

function closeTimerWindow()
{
 timerWindow.close();
}

In the query results page:

Code:

<body onload='parent.closeTimerWindow();'>
...

Is that what you're after?

Dave,

That would have worked, but onload was executing before the query had finished. I ended up setting a countdown as the query was outputted to the screen.
When the counter reached 1, I set a session variable (ColdFusion) that was accessible to the counter window which triggered it to close. (this window was periodically refreshing itself)

I really appreciate your help - JavaScript is rather finicky when used with ColdFusion.

Thanks again,
Djuna

I've never used ColdFusion, so I am unfamiliar with your exact problem, but I'm glad you figured out a solution!

Dave,
One final note. My above method worked from a browser activated within HomeSite - the editor that I use for developing, but the timer window still closed way too early with I.E. when used externally. I ended using the body tag idea - I was wrong about the query finishing before the body onload activated - but ColdFusion still refused to cooperate with JavaScript, so I tried a very inelegant, but effective method.
From the query display window, I opened another window of the same name as the timer window using the body onload, which overwrote the timer window. At this point I had active control of the window, and was able to close it.
Thanks again for your help,
Djuna

Inelegant, perhaps, but SNEAKY!
