Can a function on external js page tell which page is calling it

[ant1832]

I have a function on an external js page that I'm calling from 4 different html pages. Is there anyway I can tell which page is calling on the function? I need the function to act a little different depending on which page calls it.

Two quick ideas:

1) The caller could pass a code to the function which indicates the current page name.

2) The function can parse "window.location.pathname" to get the current page name.

OR on each of your page set a global varialbe to some number, then in the function check the value of that variable.

OR pass this number as parameter to the function.

Good idea!

loc=self.location.href
if(loc.indexOf(".html")<0) loc+="index.html"
loc=loc.split("/")
file=loc[loc.length-1]
folder=loc[loc.length-2]
domain=loc[loc.length-3]

by using this method you have choices of camparing file, folder and domain as well as loc[0], loc[1],loc[2]

I also split my domain from the location as well......

loc=loc.split("mysite.com")[1]

added: Google's cache of your site has a "+" in the location, you will need to split that from it as well as any location variabls and anchors you may use.....

loc=self.location.href
loc=loc.split("+")[0]; //escapes Googles caching
loc=loc.split("?")[0]; //escapes variables
loc=loc.split("#")[0]; //escapes anchors
if(loc.indexOf(".html")<0) loc+="index.html"
loc=loc.split("/")
file=loc[loc.length-1]
folder=loc[loc.length-2]
domain=loc[loc.length-3]
