"password" and "retype password" fields

Question

hi all,
how do i get two textfields like password and retype password to validate against each other in javascript, the two textfields names are declared below as well as the button that will hopefully call the javascript
can anyone help?
<input type="password" name="txtUserNewPassword">
<input type="password" name="txtUserReTypeNewPassword">
<input type="submit" name="btnUpdateUser" value="Update" action="<%= response.encodeURL("UpdatedUserDetails.jsp")%>">

The action attribute should be on a form tag. It doesn't apply to a submit button.
If you need dynamic actions depending on which button you push, you need to change the forms action in javascript.
To run javascript, you need to specify an onclick event on the button.
If you return false from the event, the submission will be cancelled, and they can fix it on the client side.
Something like this:
<script>
  function passwordsAreSame(){
    p1 = document.myForm.txtUserNewPassword.value;
    p2 = documetn.myForm.txtUserReTypeNewPassword.value;
    if (p1 != p2){
      alert("Please check the passwords are the same");
      return false;
    return true;
</script>
<form name="myForm" action="<%= response.encodeURL("UpdatedUserDetails.jsp")%>" method="post">
<input type="password" name="txtUserNewPassword">
<input type="password" name="txtUserReTypeNewPassword">
<input type="submit" name="btnUpdateUser" value="Update" onclick="return passwordsAreSame()">
</form>Cheers,
