Popup Object

[vbkris]

hi guys,

I have code like this:

window.open('somePage','myWin','features');


the above script is emitted by a DLL (using ASP.NET).

i cannot control how it emits that code.

now i want to check whether the popup has opened. if you notice above, no variable has been assigned to the popup.

is there any way i can detect wether a popup named 'myWin' is open currently other than going the variable way?

alternative that i have is:

theWin=window.open('somePage','myWin','features');

if(theWin)
{
//do code here
}


but implementing the above will take huge time as i have to recreate a new DLL and apply the same throughout...

With the popup window's name, to establish a local handle of it, one can do it like this.
[tt]
window.open("page_1_thisDomain.html","myWin");
//etc etc
//and at some later stage in the same function or elsewhere
var swinname="myWin"; //suppose this knowledge is retained
//A local handle of the popup will be established.
[blue]var owin_local=window.open("",swinname);[/blue]

//Establish the evidence you get the same popup handle
//[1] This shows evidence #1
//This will succeed as long as you are in the thisDomain
//Cross-domain query .location will fail
alert(owin_local.location);
//[2] This shows evidence #2
//Re-direction will succeed as long as in thisDomain.
//Again cross-domain will fail, permission denied.
owin_local.location.href="page_2_thisDomain.html";
[/tt]

vbkris,

the only way to do this, afaik, is to assign it to a variable.

you can then do a test like this:

var theWin = window.open(...);
if ( theWin && !theWin.closed ) {
   ...
}

to see if it was a window and is still open...

I meant to show the way to re-establish that handle. May be I fail...
