The function Document.Open() is not functioning correctly

As I work on my webpage, I am having an issue with a button. This button should notify the user if their username and password are correct, and then redirect them to another page. However, while the notification works fine, the redirection does not happen as intended.

Below is the code snippet for the webpage:

  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 + ";

  alert(document.cookie);
  getCookie();
}

  document.open(url);

  whole = document.cookie;
  whole = whole.split(';');
  username = whole[0];

  actual = password.split('=');
  user = actual[0];
  pass = actual[1];
  if (document.getElementById('usernameText').value !=null &&
      document.getElementById('usernameText').value!="" &&

    alert('Incorrect username or password.');

Answer №1

document.open() function is specifically designed for opening new windows or documents within the current browser window. It should be noted that this function is not intended for redirecting to a new URL. In contrast, document.write() is the appropriate function to use for writing content to the current page. However, it is important to keep in mind that using document.write() will clear the current page.

For redirecting to a new URL, the correct method to use is

window.location = 'http://example.com';
.

Answer №2

First and foremost, it is generally not advisable to use a variable name that is also the same as a function. Upon reviewing your basic HTML code, I noticed several issues. It is essential to ensure you are following best practices right from the initial stages.

Regarding this snippet of code:

function url(url){
      document.open(url); //Is 'url' referring to the function or the variable?
}

It is recommended to use the following approach:

function goto_url(url) {
  window.location.href = url; //I believe this is the functionality you intended
}

On a completely different note, trying to validate a user's password using JavaScript is akin to a bank asking you if your check is valid before cashing it.

I apologize for the confusion earlier, I meant window.location.href, but this could potentially cause a history loop if the user clicks the back button. It might be better to utilize window.location.replace(url) instead.
