Codeigniter使用jQuery显示表单成功消息？

Question

new to CI and trying to figure out how to put it all together. I have a form that i'm submitting via the form helper and using the form validation library to send feedback to the user. I'm submitting the form with a simple $('#editForm').submit();

I'd like to be able to show a success notification to the user and use jquery animations to make it appear in a smooth transition versus just showing up.

All I've been able to do so far is use flashdata to conditionally display the div containing the notification in the view file.

  <div id="success-alert" style="display:none;" class="alert alert-success alert-dismissable">
      <button type="button" class="close" data-dismiss="alert" aria-hidden="true"></button>
      Success!
</div>

Is there a way to trigger jquery to animate this? I tried just echoing out some php to conditionally display the jquery code, but it wasn't working:

<?php if($this->session->flashdata('result') == 'success') { ?>
  $('#success-alert').slideDown('slow');
  setTimeout(function() {$('#success-alert').slideUp('slow');}, 2100);
<?php }; ?>

I get this error: Uncaught SyntaxError: Unexpected token <

I'd prefer not to use flashdata, other than to conditionally execute jquery, if possible. I know there must be a way, but unfortunately too I'm new to CI to know what it is.

Answer 1

you dont have to check the value of flash data if the flash data is set then it will trigger

<?php if($this->session->flashdata('result')) { ?>
  <script>
    $('#success-alert').slideDown('slow');
    setTimeout(function() {$('#success-alert').slideUp('slow');}, 2100);
  </script>
<?php }; ?>

Note this should be in same page where your form redirects after success.
