Using dynamic variable as window name and detecting if window exists

L

lrlebron

I am trying to create popup windows with dynamic variable names and
then see if they exist or not.

For example, if I call the function like so openWin("2600","2000") I
would like the function to create a window called
"win26002000". I have tried the following code (and many other
variations) but I cannot get it to work

function openWin(senderID, recipientID)
{
//Create the window if it does not exist or it has been closed
if (typeof "win" + senderID + recipientID=="undefined" || "win" +
senderID + recipientID.closed)
{
"win" + senderID +
recipientID=window.open("popup.aspx","win" + senderID +
recipientID,"toolbar=no,menubar=no,width=350,height=350");
}
if("win" + senderID + recipientID)
{
//Do something with the window
}
}


thanks,

Luis

function openWin(senderID, recipientID) {
var W = window['win'+senderID+recipientID];
if( typeof(W)=='undefined' || W.closed)
W = window.open('','win'+senderID+recipientID,'width=350,height=350');
W.location = 'popup.aspx';
W.focus();
}

not tested ...
so perhaps :

function isWin(senderID, recipientID) {
return window['win'+senderID+recipientID];
}
function openWin(senderID, recipientID) {
if( typeof(isWin(senderID, recipientID))=='undefined' ||
isWin(senderID, recipientID).closed)
isWin(senderID, recipientID) = window.open('',
'win'+senderID+recipientID,
'width=350,height=350');
isWin(senderID, recipientID).location = 'popup.aspx';
isWin(senderID, recipientID).focus();
}

error:
