Question

Here is an example:

I have a file 1.js, which has some functions. I have to make them available to another file 2.js.
1.js is not included in the page, but 2.js is (using src=”).

Is there a way to do this? I do not want to expose 1.js at all to the users, but want to use its functions in 2.js

Answer 1

Description

JavaScript works on the client (Browser) so you have to make the file available to them.
Consider to encode and minify the file to make it harder to read.

Update

1. You can do a Ajax call to get the javascript and use eval. I would do it this way using jQuery .load().

2. It is possible to include a javascript-file using javascript like this

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

   }

Then you can call methods from the other script / source. But this is visible to the user and experienced users will find this.
Its harder to find as a simple

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