javascriptevalsyntax-checking

JavaScript syntax check with JavaScript?

How could a Commando like me check if inputed code is a valid JavaScript source using some JavaScript built-in methods (if any!) or in any other possible way!? (Something like a preparser found in various IDE's like NetBeans, Eclipse, etc)?

I have to check if code is OKAY and then window.eval()-it to the current document instance.

Solution

  • You could use a lint library like:

    EDIT:

    Sorry, that's a compiled linter and you're wanting something for on-the-fly. Try jslint: http://jslint.com
