      <title>test javascript</title>
  <head>
  <body>
     <script language="javascript">
           document.write(3*2);
           document.write("test string");
           document.write("<br>");
           document.write("test end");
           var test =new array(2);
           test[0]="haha";
           test[1]="1";
          document.write(test[0]);
           document.write(test[1]);
           document.write(5);     </script>
