I found this to be a neat little trick for hiding(somewhat) source javacscript code from peering eyes...

This function will unload all linked javascript files so that when you view source - you see no javascript files! (Especially helpful when using FF and using web-developer tools - no linked js files are displayed) The files remain resident in memory - allowing for the functions to work.

Just call the function in the tag

function unloadJS(scriptName) {

  var head = document.getElementsByTagName('head').item(0);

  var js = document.getElementById(scriptName);

  js.parentNode.removeChild(js);

}

function unloadAllJS() {

  var jsArray = new Array();

  jsArray = document.getElementsByTagName('script');

  for (i = 0; i < jsArray.length; i){

    if (jsArray[i].id){

      unloadJS(jsArray[i].id)

    }else{

      jsArray[i].parentNode.removeChild(jsArray[i]);

    }

  }        

}
