" +                "you have " + count + t + " left.");         document.myform.username.value = "";         document.myform.pword.value = "";         settimeout("document.myform.username.focus()", 25);         settimeout("document.myform.username.select()", 25);         count --;     }      else {         alert ("still incorrect! have no more tries left!");         document.myform.username.value = "no more tries allowed!";         document.myform.pword.value = "";         document.myform.username.disabled = true;         document.myform.pword.disabled = true;         return false;     }  } </script>      <style>      p.log_on{     position: fixed;     top: 30px;     left: 20px; } </style>      </head>   <body>  <form name = "myform">   <p class="log_on">     enter user name <input type="text" id="username"><br><br><br><br><br>     enter password <input type="password" id="pword">     <input type="button" value="check in" id="submit" onclick="validate()">   </p> </form>  </body>   </html>

in function create login you:

  1. you use undefined arrays unarray , pwarray
  2. you push arrays string not value of variables
  3. you save local storage empty array.
