I can do this easily in PHP but how can I get just the filename (with no extension or domain) in Javascript.


alert(location.pathname);

Will return: "etc/etc/etc/bobs_page.html"

But I only want "bobs_page" read into my variable. Does javascript have an equivilant to getBaseName?

Thank you.

var path_name=location.pathname;
var base_name=path_name.lastIndexOf("/")+1;
alert(path_name.substring(base_name));

Hey thanks!!
Exactly what I was looking for; here is how I finished it after looking up 'substring' and 'lastIndexOf' based on your suggestion.


// get instructor name
var pathName=location.pathname;
var startLoc=pathName.lastIndexOf("/")+1;
var endLoc=pathName.lastIndexOf("html")-1;
var instructorName = pathName.substring(startLoc, endLoc);

You can also take out the 'var endLoc' line and just do:


var instructorName=pathName.substring(startLoc, pathName.length-5);

It does the same thing as the endLoc variable but it basially counts how many characters are in the whole string and then subtracts 5 characters from the end of the string and those 5 characters will be '.html'. Its just a shorter way to do the same thing, just giving you some options.
