| http://www.gnu.org/philosophy/javascript-trap.html Our tentative policy is to consider a JavaScript program nontrivial if: * it makes an AJAX request or is loaded along with scripts that make an AJAX request, * it loads external scripts dynamically or is loaded along with scripts that do, * it defines functions or methods and either loads an external script (from html) or is loaded as one, * it uses dynamic JavaScript constructs that are difficult to analyze without interpreting the program, or is loaded along with scripts that use such constructs. These constructs are: - using the eval function, - calling methods with the square bracket notation, - using any other construct than a string literal with certain methods (Obj.write, Obj.createElement, ...). How do we tell whether the JavaScript code is free? At the end of this article we propose a convention by which a nontrivial JavaScript program in a web page can state the URL where its source code is located, and can state its license too, using stylized comments. |
