JavaScript Include Files?

I have JavaScript functions that I'm using in different pages. Is there a way to do a C/C++ type include so I don't have to replicate the JavaScript code on every page?

What you're after is the SRC attribute of the tag. It's easy to miss the superfluous trailing tag, but it is required. Finally, you can even degrade gracefully if, for some reason, the browser can't load the JS file you referenced. Just add some code between the tags that contain the SRC attribute. This code will be ignored if the file pointed to by the SRC can be read correctly and will display your custom error message, otherwise.
