Hi all this is my first post! I'm searching for the past two days for a solution. and many times google results linked to this website. but i couldnt get a reasonable solution so i'm asking here 'once' again.
heres the problem
there is a main page, lets say main.html. from there u can click a link (a href) to login (login.html), after validating the page is redirected to main.html and there I want to change the 'login' link to 'logout'
main.html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="../../../style1.css">
<script language="JavaScript" src="../../../script.js" type="text/javascript"></script></head>
<body onLoad="window.focus();">
<h1>Data Base Systems</h1>
<div id="login"><a href="../login.html">Login</a></div>
</body>
</html>
login.html
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<link rel="stylesheet" type="text/css" href="../../style1.css"><script language="JavaScript" src="../../script.js" type="text/javascript"></script></head>
<body onLoad="document.frmLogin.txtUsername.focus();">
<form method="post" name="frmLogin">
<h1>Login</h1>
<table>
<tr>
<td>Username: </td>
<td><input type="text" id="txtUsername" name="txtUsername"></td>
</tr>
<tr>
<td>Password: </td>
<td><input type="password" id="txtPassword" name="txtPassword"></td>
</tr>
<tr>
<td><input type="button" value="Login" onClick="logIn();"></td>
<td> </td>
</tr>
</table>
</form>
</body>
</html>
script.js
function logIn() {
// get the courseid value from URL parameter to know for which course the user is logged in
var courseid = getParamValue('courseid');
courseid = courseid.toLowerCase();
// get form element values 'txtUsername' and 'txtPassword'
username = document.frmLogin.txtUsername.value;
username = username.toLowerCase();
password = document.frmLogin.txtPassword.value;
password = password.toLowerCase();
// <-- here comes the validation
if(loggedIn) {
var newwin = window.open(courseid+"/summary.html","_self");
if(window.focus) {newwin.focus()}
newwin.document.getElementById("login").innerHTML = 'Logout'; // [COLOR="Red"]<-- this isnt working[/COLOR]
}
I'm using IE7. Didnt work in firefox either.
What all I tried:
- instead of var newwin = window.open(courseid+"/summary.html","_self");, i tried var newwin = self.location.replace(courseid+"/summary.html");
- tried newwin.onload = function () {
setTimeout('location.reload()',1000); //<- donno which function I should call inside setTimeout
}
- tried windows.opener method. got this code somewhere online
var WindowRef = null;
function openWindow(url, name, props) {
if(@cc_on!@false){ //do this only in IE
var WindowRef = window.open("", name, props);
WindowRef.close();
}
var WindowRef = window.open(url, name, props);
if (!WindowRef.opener) {
WindowRef.opener = self;
}
WindowRef.focus();
return WindowRef;
}
and calling var newwin = openWindow(courseid+"/summary.html","_self","");
what worked:
it still can call newwin.document.getElementById("txtUsername").value means it still could checkelements in login.html
Thank you for any help.
