JavaScript error with the global variables, an example
876 bytes, text/html
Details 
User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

Please try the page below, the global variables will never print out correctly.
I teach javascript for 3 years now (my other email is akattan@hu.edu.jo).
<html>
<head>
  <title>Global Variables in JS</title>
  <script type="text/javascript">
  <!--
   var x = 10, y = 2.13 , str = "anything";

   function printGlobal() {
     document.writeln(x);         //Only this variable will be printed
     document.writeln(y);         //this will not print ?!
     document.writeln(str);       //this will not print ?!
   }

   function printLocal() {
   var x = 5, y = 1.25 , str = "something";
     document.writeln(x);
     document.writeln(y);
     document.writeln(str);
     document.writeln("Global x is "+this.x); //this will not print ?!
   }
       //-->
</script>
</head>
<body>
  <p>Click to start</p>
  <form>
     <input type="button" value="print Globals" onclick="printGlobal()"/> &nbsp;
&nbsp;
     <input type="button" value="print Locals" onclick="printLocal()"/>
  </form>
</body>
</html>


Reproducible: Always

Steps to Reproduce:
Any Global variable will lose its setting for some reason
Please check the program above
Actual Results:  
Incorrect results each time for every global variable in JavaScript when using any 
event like onclick, onmouseover, etc.

Expected Results:  
Run the script I gave above in any other browser and see the difference...

I'm an assigned lecturer at the IT College/ Hashemite University / Jordan
I teach web programming and Java. I like your browser and I would love to help
make it better. 
Please check this problem
