Document.Open() will not work[SOLVED]

Posted 21 January 2012 - 07:30 PM

So, I have a button where if the person's username and password is correct, it will notify you, then it will redirect to another page. The first thing works, but it will not redirect you to the page.

Here is the code of the webpage:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Siur</title>
<script type="text/javascript">
///////////////////////////Login System///////////////////////////
function getCookie()
{
	var whole, username, password, splitting, actual,user, pass;
	whole = document.cookie;
	whole = whole.split(';');
	username = whole[0];
	password = whole[1];
	actual = password.split('=');
	user = actual[0];
	pass = actual[1];
	alert(user + password);
}

function setCookie(c_name,value,exdays)
{

var c_value=value + "; pass="+document.getElementById('passwordText').value;
document.cookie="=" + value + "; pass="+document.getElementById('passwordText').value;
alert(document.cookie);
getCookie();
}
function url(url)
{
	  document.open(url);
}
function checkCookie()
{
		var whole, username, password, splitting, actual,user, pass;
	whole = document.cookie;
	whole = whole.split(';');
	username = whole[0];
	password = whole[1];
	actual = password.split('=');
	user = actual[0];
	pass = actual[1];
if (document.getElementById('usernameText').value !=null && document.getElementById('usernameText').value!="" && document.getElementById('passwordText').value == pass)
  {
  alert("Welcome again " + user);
  document.open('search_webpage.html');
  }
else
  {
 alert('Incorrect username or password.');
  }
}

I will keep looking for fixes, but I could not solve the problem.

first off, its generally not a real good idea to use a variable name that also refers to a function...

function url(url)
{
      document.open(url); //is url the function or the variable?
}


instead... use
function goto_url(url) {
  window.href.location = url; //I think this might be what you are looking for
}


On a totally seperate note, validating the user's password using javascript is like a bank asking you if your check is good before agreeing to cash it.

my apologies, i meant "window.location.href", but could cause a history loop if they click the back button.. Perhaps better to use "window.location.replace(url)"

or window.open(url);

what document.open() does:

Mozilla Developer Network said:

The document.open() method opens a document for writing.

If a document exists in the target, this method clears it.

Also, an automatic document.open() call happens when document.write() is called after the page has loaded, but that's not defined in the W3C specification.

Do not confuse this method with window.open(). document.open allows you to overwrite the current document or append to it, while window.open provides a way to open a new window, leaving the current document intact. Since window is the global object, just calling open(...) does the same as window.open(...).

Thank you for all the help. I was taught that document.open() opens another document and displays it, but it seems not.

Well, the solution worked. The login system is still being worked on, for it needs more security factors to it.
