Easier method is window location href    http   example com new url    But what if you want to check if username and password whether empty or not using JavaScript and send it to the php to check whether user in the database  You can do this easily following this code   html form -   lt form name  myForm  onsubmit  return validateForm    method  POST  action  login php   gt                lt input type  text  name  username  id  username    gt       lt input type  password  name  password  id  password    gt       lt input type  submit  name  submitBt value  LogIn    gt   lt  form gt    javascript validation-  function validateForm        var uname   document forms  myForm    username   value      var pass   document forms  myForm    password   value       if   isEmpty uname   Log In     amp  amp    isEmpty pass   Password               return true       else          return false           function isEmpty elemValue  field       if  elemValue            elemValue    null            alert  you can not have   field   field empty            return true       else          return false            check if user in the database using php   lt  php      con   mysqli connect  localhost   root   1234   users         if mysqli connect errno             echo  Couldn t connect   mysqli connect error         else            echo  connection successful  lt br   gt                uname tb     POST  username         pass tb     POST  password          query   SELECT   FROM user        result   mysqli query  con  query        while  row   mysqli fetch array  result            if   row  username       uname tb   amp  amp    row  password       pass tb                echo  Login Successful               header  Location  dashbord php                exit             else              echo  You are not in our database  mysqli connect error                        mysqli close  con     gt

You cannot sanely depend on client side JavaScript to determine if user credentials are correct  The browser  and all code that executes that  is under the control of the user  not you  so it is not trustworthy   The username and password need to be entered using a form  The OK button will be a submit button  The action attribute must point to a URL which will be handled by a program that checks the credentials   This program could be written in JavaScript  but how you go about that would depend on which server side JavaScript engine you were using  Note that SSJS is not a mainstream technology so if you really want to use it  you would have to use specialised hosting or admin your own server    Half a decade later and SSJS is much more common thanks to Node js  it is still fairly specialised though    If you want to redirect afterwards  then the program needs to emit an HTTP Location header   Note that you need to check the credentials are OK  usually by storing a token  which isn t the actual password  in a cookie  before outputting any private page  Otherwise anyone could get to the private pages by knowing the URL  and thus bypassing the login system

Verifying that a user is an admin in javascript leads to trouble because javascript code is visible to anyone  The server is the one who should tell the difference between an admin and a regular user AFTER the login process and then generate the new page accordingly    Maybe that s not what you are trying to do so to answer your question   window location href   lt the page you are going to gt
