use an inline javascript function (not jquery) on drupal 7 This is how jQuery is included in d7

(function ($) {
  // jquey codes here  
})(jQuery);


How i can include javascript code (not jquery) in d7?
If you want to write a plain JavaScript instead of JQuery, You can proceed with normal function declaration like

function sample() {
}


and go ahead. It is normal way of the doing things in javascript, More over jQuery is a framework of javascript and as said you can add js files in the traditional way

drupal_add_js()
