Javascript and HTML function issue 

<script stylesheet="text/javascript">
var statename;
function confirmReview(formObj){
 function myState( val ){
 statename = val;
 alert( "This is " + statename );
 }
 postcode = document.getElementById("postcode");
 //Folowing code
 if( statename== "Selangor" ){
 if( postcode < 10000 || postcode > 40000 )
 alert( "Invalid postcode for " + statename );
 }
}
</script>
<body>
<form name = reviewform onsubmit="return confirmReview(reviewform)" method=POST>
 <select id='state' onchange="myState(this.value);">
 <option>Specify state or territory</option>
 <option value="Selangor">Selangor</option>
 <option value="Terengganu">Terengganu</option>
 </select>
</form>
</body>

my question is how to store the value and save it to the statename as i fail to run in my HTML javascript code. can anyone teach?

i cannot print out my statename example if i want to make some comparison for my postcode when i load the script it run to the funciton . my HTML will just clear all the data like refresh the page without showing anything

    @alex23 — If there are any such browsers, they are no longer in use. Browsers have defaulted to assuming JS forever and HTML 5 makes the attribute explicitly optional. Commented May 12, 2013 at 9:13

    @Chirs, put the validation code (the code with the alert) in the myState function as well. Commented May 12, 2013 at 9:38

    @Chirs, now the alert part is within function confirmReview(formObj) (good, I guess), but function myState is also defined within function confirmReview(formObj), hence will no longer be found by onchange="myState(this.value);" Also note that confirmReview should return true or false. See Show me a Simple javascript onSubmit handler. PLEASE NOTE: by changing your question, you've also made imulsion's answer outdated. That's not nice.
