Back button problem

micmac

Hi all,
I have created a HTML form that contains several fields.
One particular field is populated by regions within Australia.
Depending on what region is selected another drop down list below it is populated (via javascript) with relevent hotels in that region.
This all works fine, however, if one of the many fields is not filled out i bring the user to an error page that contains a back button.
Now for the problem. If they go back the form displays all the previous data that they entered except for the hotels drop down list which is the drop down list populated (through javascript) depending on what region was selected.
Can anyone tell me of a way to fix this?
Is there a way of passing the value back via the back button?
Any ideas?

Cheers,
micmac

The best way to get around this is check the fields BEFORE you submit the page. (via javascript)...maybe something like this...

<SCRIPT LANGUAGE="JavaScript">

<!-- Begin
function checkrequired(which) {
var pass=true;
if (document.images) {
for (i=0;i<which.length;i++) {
var tempobj=which.elements[i];
if (tempobj.name.substring(0,8)=="required") {
if (((tempobj.type=="text"||tempobj.type=="textarea")&&
tempobj.value=='')||(tempobj.type.toString().charAt(0)=="s"&&
tempobj.selectedIndex==0)) {
pass=false;
break;
         }
      }
   }
}
if (!pass) {
shortFieldName=tempobj.name.substring(8,30).toUpperCase();
alert("Please make sure the "+shortFieldName+" field was properly completed.");
return false;
}
else
return true;
}
//  End -->
</script>
</head>
<body>
<center>
<form onSubmit="return checkrequired(this)">

<input type="text" name="requiredname">
<br>
<input type="text" name="requiredemail">
<br>
<select name="requiredhobby">
<option selected>Pick an option!
<option>1
<option>2
<option>3
</select>
<br>
<textarea name="requiredcomments"></textarea>
<br>
<input type=submit value="Submit">
</form>
</center>
</body>

Since you are already using javascript...save yourself and your users some aggravation and check it at the clientside via javascript before you deal with the page serverside.
