Instead of recommending the usual  turn off the JSHint globals   I recommend using the module pattern to fix this problem  It keeps your code  contained  and gives a performance boost  based on Paul Irish s  10 things I learned about Jquery     I tend to write my module patterns like this    function  window           Handle dependencies     var angular   window angular              window            document   window document          Your application s code   window     You can get these other performance benefits  explained more here     When minifying code  the passed in window object declaration gets minified as well  e g  window alert   become m alert    Code inside the self-executing anonymous function only uses 1 instance of the window object  You cut to the chase when calling in a window property or method  preventing expensive traversal of the scope chain e g  window alert    faster  versus alert    slower  performance  Local scope of functions through  namespacing  and containment  globals are evil   If you need to break up this code into separate scripts  you can make a submodule for each of those scripts  and have them imported into one main module

If you are using a relatively recent version of JSHint  the generally preferred approach is to create a  jshintrc file in the root of your project  and put this config in it          globals                  false           This declares to JSHint that   is a global variable  and the false indicates that it should not be overridden   The  jshintrc file was not supported in really old versions of JSHint  such as v0 5 5 like the original question in 2012   If you cannot or do not want to use the  jshintrc file  you can add this at the top of the script file     globals   false      There is also a shorthand  jquery  jshint option as seen on the JSHint options page
