To extract the filename from the current location, you could use something
like this:

thisPage = location.pathname.substr(location.pathname.lastIndexOf('/')+1);

Is that what you were after?

It will help you slightly, but Javascript is not Java. Their syntaxes
are similar, but not equal.

if mid(str,i,1)="/" then
str= mid( mid(str,i+1,100),1,len( mid(str,i+1,100))-4)
str="../../../aspx/quotes"+str+".aspx"
GetWriterName="../../../aspx/quotes"+str

Do you really mean this? The result will be

"../../../aspx/quotes../../../aspx/quotes"+filename+".aspx;

I don't even think there is a "/" in front of the filename.
I guess one of them are superflous.

A solution:
---
function getWriterName() {
var str = location.pathname; // easier than working with full href.
for (var i = str.length ; i > 0 ; i--) {
if (str.charAt(i)=="/") {
str = str.substring(i+1); // no second argument means until end of string
return "../../../aspx/quotes/"+str+".aspx";
}
}
}
---
Now for the easier way:
---
function getWriterName() {
var str = location.pathname;
var i = str.lastIndexOf("/");
return "../../../aspx/quotes"+str.substring(i)+".aspx";
}
