How do tell a browser not to offer to save an incorrect password?

Question

Often on a website, if I enter the wrong password by mistake, I get a page back that indicates the wrong credentials, but Chrome (Or whatever) prompts me with "Would you like to remember this password?"

Is there any way to hint to the browser that now is not the time to ask, so that it only prompts if the user enters a correct password?

You could use JQuery & Ajax to post the login form to the server and recieve a response back without ever reloading the page, thus avoiding this problem altogether.

EDIT

Something along the lines of this (untested):

<div id="error"></div>
<form id="loginForm" method="post">
  <input type="username" name="username" id="username">
  <input type="password" name="password" id="password">
  <input type="submit" value="Login">
</form>

<script>
  $(function(){
   $('#loginForm').submit(function(){
     // Ajax to check username/pass
    $.ajax({
      type: "POST"
    , url: "/login"
    , data: {
        username: $('#username').val()
      , password: $('#password').val()
      }
    , success: function(response) {
        if(response == 'OK'){
          $('#loginForm').submit()
        } else {
          $('#error').html('Invalid username or password')
        }
      }
   })
  })
</script>
