What are you expecting that code to do? It isn’t really set up to do anything with the retrieved data. Normally you’d want to place it on the page once you’ve retrieved it. Anyhow, the code works to get the contents of the file. For me, in Chrome at least, I get an alert of the contents of 3.htm.

Your script is in an odd location, though—wedged between the </head> and <body> tags. Preferably, move it to the bottom of the page, just before the </body> tag … or at least put it in the <head> section.
