Dialog Arguments

[James Davidson]

I have created the following example dialog box. It works fine except for one thing: alert("show(1) = "...) displays undefined. Why? Should I not be able to reference the global variable arguments inside the function show()? The init() method is invoked in the onload event. The alert("global = "...) and alert("show(2) = "...) display the value I expect. What am I overlooking?

 
var arguments = null;
 
function init()
{
arguments = window.dialogArguments;
alert("global = " + arguments.title);
}
 
function show(name)
{
//arguments = window.dialogArguments;
alert("show(1) = " + arguments.title);
var args = window.dialogArguments;
alert("show(2)= " + args.title);
 
if (name == "Google")
{
url = "www.google.com";
}
 
if (name == "Yahoo")
{
url = "www.yahoo.com";
}
 
var object = new Object();
object.url = url;
 
window.returnValue = object;
window.close();
}
