Why doesn't this JavaScript code work as expected? -

-

this tiny javascript, along css supposed prevent duplicate entries database freezing screen after submit has been clicked.

so far, out of on 200 people have used app submit entries, 6 of them have managed submit duplicate entries.

we suspecting older browsers may responsible double entries.

we still investigating.

could assumption correct?

if yes, there way improve code work on browsers?

i keep code, rather go because of pleasant , feel open better.

<script type="text/javascript">     function freezescreen(msg) {         scroll(0, 0);         var outerpane = document.getelementbyid('freezepane');         var innerpane = document.getelementbyid('innerfreezepane');         if (outerpane) outerpane.classname = 'freezepaneon';         if (innerpane) innerpane.innerhtml = msg;     } </script>

--css

<style type="text/css">    .freezepaneoff    {       visibility: hidden;       display: none;       position: absolute;       top: -100px;       left: -100px;    }     .freezepaneon    {       position: absolute;       top: 0px;       left: 0px;       visibility: visible;       display: block;       width: 100%;       height: 100%;       background-color: #666;       z-index: 999;       filter:alpha(opacity=85);       -moz-opacity:0.85;       padding-top: 20%;    }     .innerfreezepane    {       text-align: center;       width: 66%;       background-color: #171;       color: white;       font-size: large;       border: dashed 2px #111;       padding: 9px;    } </style>

i posting response here since thing wouldn't allow me add comments stupid message 1 comment per 5 seconds allowed , has been 10 minutes since last comment added.

thanks alot @ppvg , @random. need 1 of guy's script (more @random's because don't understand @ppvg meant //...do submitting stuff...) need use 1 of guy's js in addition 1 using? also, asp.net allow form action="~" ...?

i agree @random. disable submit button , prevent form's default action after submitting once. this:

var submitted = false; var form = document.getelementbyid('form_id'); var submitbutton = document.getelementbyid('submit_button_id');  form.onsubmit = function() {     if (submitted) {         freezescreen("already submitted!");         // stop form being submitted second time:         return false;     }      // ... submitting stuff ...      submitted = true;     submitbutton.disabled = true; }
