If the password protection mechanism provided by the Web server is not available, a simple way to protect a page with JAVASCRIPT is to match the user password with the filename to be loaded.
<HTML><HEAD>
<SCRIPT>
function login() {
if (validLogin()) {
password = document.userInfos.password.value;
self.location.href=
"http://www.server.com/login/"+password+".html";
}
}
function validLogin() {
if (isBlank(document.userInfos.password.value)){
alert("Can't be blank");
document.userInfos.password.focus();
return false;
}
return true;
}
function isBlank(s) {
return (s == "");
}
</SCRIPT>
<BODY onLoad="document.userInfos.password.focus();">
<H1><CENTER>Identification </H1></CENTER>
<CENTER><TABLE BORDER=1>
<FORM NAME=userInfos>
<TR><TD>Password: </TD><TD>
<INPUT TYPE="password" NAME=password LENGTH=20>
</TD></TR>
<TR ALIGN=center>
<TD></TD><TD>
<INPUT TYPE="button" VALUE="Ok" onClick="login()">
</TD></TR></TABLE></FORM></CENTER></BODY></HTML>
