Only using one 'var' is a best practice to prevent problems related to 'variable hoisting'
This link provides a good explanation/video: http://net.tutsplus.com/tutorials/javascript-ajax/quick-tip-javascript-hoisting-explained/ Not sure about the online tool, but I assume you can download jslint and set it up on your own system, there should be options to configure it. If you happen to be using VS2010 there is a good plugin that integrates jslint and also allows you to turn various options on and off. http://jslint4vs2010.codeplex.com/ Hope this helps! -- To view archived discussions from the original JSMentors Mailman list: http://www.mail-archive.com/jsmentors@jsmentors.com/ To search via a non-Google archive, visit here: http://www.mail-archive.com/jsmentors@googlegroups.com/ To unsubscribe from this group, send email to jsmentors+unsubscr...@googlegroups.com
