How to enable # javascript?

Say my javascript scripts are not embedded in html / xml ... I want to write a small library of helper functions for use in my scripts. Obviously, javascript should have the keyword "#include" or "require", but I cannot find it. Everything I could with Google relies on code that is part of html / xml, which in my case does not help. What should I do?

I believe that you want to write some kind of dependency tracking structure for your javascript files and use the "Lazy-Loading" process to download the necessary JS file only when necessary.

Check out Using.js , it seems to be doing what you need.

You can also check addModule on YUILoader . It allows you to load non-YUI infrastructure components on the fly.

This is actually not #include or require in javascript. You really have to handle all the dependencies yourself. I saw people doing hack where they do document.write to include other javascript files.

in the event that you do not care, there is an include version that uses the document object via the DOM interface:

 function include(aFilename) { var script = document.createElement('script'); script.src = aFilename; script.type = 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(script) }

the problem is that you have to include this function in the whole source file that needs ...: P: P

include js file in html:

 <script type="text/javascript" src="..."></script>

it should be in the page title for correctness.
