php - Display error messages from serverside through javascript -


i have 3 files in total. login.html - login.js - login.php

function login(){     $(document).ready(function(){         var epost = document.getelementbyid("epost").value;         var passord = document.getelementbyid("passord").value;         $.ajax({             type: 'post',             url: 'login.php',             data: "epost=" + epost + "&passord=" + passord,             success: function(result){             }         });     }); }

here php-file:

<?php  require 'db.php'; session_start();  if(!$_post['epost'] || !$_post['passord']){     echo "type in username , password"; } else{     $stmta = $dbo->prepare("select * kunde epost = ?");      $stmta->execute(array($_post['epost']));     $login = $stmta->fetch();      if(empty($login)){         echo "user not exist";     }     else {         $passord_db = $login['passord'];             $passord = md5($_post['passord']);                if($passord_db != $passord){                         echo "invalid password";         }         else{             $active = $login['active'];                  $epost = $login['epost'];                     if($active == 0){                 echo "activate account ($epost) ";             }             else{                 $_session['epost'] = $epost;             }         }     } } ?>

this may silly question, appologize in advance, how can these error-messages shown through js-script instead of php-script?

in javascript have success property function(result) variable result contain output printed php file. can use javascript inject output (error messages) anywhere in html.
