问题描述：

I always will be send to to the else.

I have the page functions.php with all my functions we are now looking at the function registerNewAcc():

<?
function registerNewAcc()
{
  return false;
}
?>

Then i got the page registerHandler.php where im checking if the function registerNewAcc() == false:

<?
if (registerNewAcc() == false)
{
  echo '<div class="invisible"></div>';
  echo 'fout';
}
else
{
  echo 'You are register succesfull!<br>Check your e-mail, we have send you an e-mail with a verification-link in it to verify your account.';
}
?>

And in my form.js file I find the class .invisible:

<script type="text/javascript">
  var registerStatus = $(data).find(".invisible");
  if (registerStatus.length >= 1) {
    //Kijkt of er regisratie fout is
    $("div.statusBalk").hide().slideDown().css("display", "block").css("background-color", "red").empty().append(data);
    $("span.inputCheck").empty();
    $inputs.prop("disabled", false);
  } else {
    //Kijkt of er regisratie fout is
    $("div.statusBalk").hide().slideDown().css("display", "block").css("background-color", "green").empty().append(data);
    $("span.inputCheck").empty();
    $inputs.prop("disabled", false);
  }
</script>

But its always go to the else of the js script. He always display 0 elements found.

I alerted it and it display 0

[ADDED]

<script type="text/javascript">
  $( "form#registerForm" ).submit(function( event ) {
    // Stop form from submitting normally
    event.preventDefault();
    var $form = $(this);
    var $url = "registerHandler.php?action=registerCheck";
    var $inputs = $form.find("input");
    var posting = $.post($url, $form.serialize());
    $inputs.prop("disabled", true);
    posting.done(function (data) {
      var formStatus = $(data).find(".inputCheckCross");
      if (formStatus.length >= 1) {
        //Wanneer het formulier fout is
        $("div.registerError").hide().fadeIn().css("display", "block").empty().append(data);
        $("div.statusBalk").css("display", "none");
        $("span.inputCheck").empty();
        $inputs.prop("disabled", false);
      } else {
        var registerStatus = data.find(".invisible");
        if (registerStatus.length >= 1) {
          //Kijkt of er regisratie fout is
          $("div.statusBalk").hide().slideDown().css("display", "block").css("background-color", "red").empty().append(data);
          $("span.inputCheck").empty();
          $inputs.prop("disabled", false);
        } else {
          //Kijkt of er regisratie fout is
          $("div.statusBalk").hide().slideDown().css("display", "block").css("background-color", "green").empty().append(data);
          $("span.inputCheck").empty();
          $inputs.prop("disabled", false);
        }
      }
    });
  });
</script>

This is the whole js part of what i check.

Found the thing, it is weard but it works now.

I had to change the line:

//From
if (registerStatus.length >= 1) {
//To
if (registerStatus) {

I think its weard because I do this also earlyer on the same way on the line with the data:

$(formStatus.length >= 1) {

And there it is working.

I think i have a idea why it didn't work but im not sure.
The count elements of .invisible is 1 and its always 1 there are not more of it. So maybe that is the thing?

Hope you guys have on this a suggestion, leave it in the comments please.

答

I'm unsure what you're trying to accomplish with $(data).find(".invisable"). Seems like an incorrect selector to me. Try using $(".invisable").length instead.

答

It seems like the misspelling of "invisible" in some places in the code may be your problem.

correct: invisible

incorrect: invisable

答

There is something I found,
when I click for the first time on the submit button it shows the green bar when I click for the second time on the submit button it shows the red bar.

Still dont know what the problem can be :s

Hope this can help.
