javascript variable-scope

[tores]

Hi.

When loading a page I include this js-file so I can use it's functions later on. In this file i have a global variable, whisch is an array.
Later on I call a debugging function in this file 2 times, each time creating a new popup-window with some debugging-info. The references to the windows is stored in the global array (using array.unshift()).
However later on when accessing the array only the last window-object is contained in the array, and the array.length is 1, not 2 as expected. It seems that when calling my debug-function a second time the reference to the first window is "forgotten". Why is this? Shouldn't the global array be able to hold a reference across function-calls?

You'll have to show us the relevant functions.

This is part of the file I'm talking about. debugwin is global and opendebugwindow is the function called twice. As explained earlier the second time I'm calling it the alert statement should print 2, not 1.

regards tores

var debugwin = new Array();
//*********************//
// Debugging functions //
//*********************//
function opendebugwindow(debugmsg){
 if(navigator.appName == "Netscape"){
 var name = debugmsg;
 }else if(navigator.appName == "Microsoft Internet Explorer"){
 var name = alphabetize(debugmsg);
 }else{
 alert("Could not show debuginfo because the browser, "+navigator.appName+", is unknown");
 return;
 }
 debugwin.unshift(window.open('', name, 'height=600, width=400, scrollbars=yes, resizable=yes'));
 /* Always prints 1! */
 alert(debugwin.length);
 debugwin[0].document.write(debugmsg);
 debugwin[0].document.close();
 
 if(navigator.appName == "Netscape")
 debugwin[0].addEventListener("keydown", ff_eventhandler, true);
 else
 debugwin[0].document.onkeypress = ie_eventhandler;
}

I'm not getting that behaviour (IE6 & FF).

debugwin.length is always incremented.
