Close Child Window via Parent using setTimeout

[John Smith]

I would like to close a child window I opened from the parent using
setTimout. I have the function below, but it always returns the error
"sendWindow is undefined".

I would appreciate any pointers.


function sendWindow()
{
var sendWin =
window.open('about:blank','sendwindow','width=100,height=100');
setTimeout('sendWin.close()',200);

}

Thank you

I meant to write "sendWin is undefined". I apologize for any
confusion.

function sendWindow()
{
var sendWin =
window.open('about:blank','sendwindow','width=100,height=100');
setTimeout('sendWin.close()',200);

}

Statements executed by setTimeout() run in the global execution
context, your variable sendWin is defined in your local function
context only (by using "var" inside the function).

Either you have to make sendWin global ...

var sendWin;
function sendWindow() {
sendWin = window.open(...);
setTimeout("if (sendWin && !senWin.closed) sendWin.close()", 200);
}

.... or you may use a closure, what means keeping sendWin
accessible in an nested function (JS1.2+) ...

function sendWindow() {
var sendWin = window.open(...);
setTimeout(function() {
if (sendWin && !senWin.closed) sendWin.close();
}, 200);
}

ciao, dhgm
