Help! Access Denied

The browser shows the alert but causes an error "access denied" and
fails to set the upload.value to null. Please help!

for(var i=0; i < fileName.length;i++) {
if (fileName.charAt( i) ==' ' || fileName.charAt(i) == '*') {
document.forms[0].upload.value='';
alert("No spaces/wildcards allowed in file names"
+ f.upload.value);

return;
}
}

You cannot set in HTML, nor alter via a script, the value of a file
INPUT element. That would potentially allow a malicious author to upload
any file they wanted from a user's machine.

Not to mention that's a pretty inefficient way to check for spaces or
wildcards. Let String#indexOf() do the work for you.

if (fileName.indexOf(' ') != -1 || fileName.indexOf('*') != -1)
{
// fileName contains a space or *
}
