Question CHAPTER 11 ERROR.

Hello, My name is Caden Ratcliff and i am 13 years old. it is my second time going through "Beginning ASP.NET 4 in visual basic and c#" . my language of choice is visual basic. My father has been doing ASP.NET for years and we are just flabbergasted on this one "Try it out" on page 395 at the end of the try it out, it says that when you complete the form a load bar will do a slide operation till it reaches the top of the form. it did. BUT, the problem is that when the message sent box comes up it does not grow long and shorten again it just stays short. Me and my dad have been racking our brains trying to find something wrong and we just cant see anything wrong. Help fellow nerds!

Hi Caden,

Can you post the code for the page (the markup as well as the code behind)? And which browser are you using?

Hope you like the book, and please say Hi to your dad....:-)

By the way: this code is in a user control. there is nothing but a few placeholders and the user control on the page it is providing for.

Well, I am Imar Spaanjaars, not Imar Spannjjaares, but yes, I am the writer of the book ;-)

Anyway, take a look at this:

Code:
$(function () {
  $(':input[type=text], textarea').each
  (
  
  // Other code here
  
  function pageLoad() {
    $('.Attention').animate({ width: '600px' }, 3000).
    animate({ width: '100px' }, 3000).fadeOut('slow');
  }
});
You have nested the pageLoad function *inside* the document ready function for jQuery. It won't be fired found by the AJAX library there and is thus not executed. Move it down a bit and it should work. Here's the full, working piece of code:

Code:
<script type="text/javascript">
  $(function () {
    $(':input[type=text], textarea').each
    (
    function () {
      var newText = 'Please enter your ' +
      $(this).parent().prev().text().toLowerCase().trim();
      $(this).attr('value', newText);
    }).one('focus', function () {
      this.value = '', this.className = ''
    }).addClass('Watermark').css('width', '300px');
    $('form').bind('submit', function () {
      if (Page_IsValid) {
        $('#TableWrapper').slideUp(3000);
      }
    });
  });
  function pageLoad() {
    $('.Attention').animate({ width: '600px' }, 3000).
    animate({ width: '100px' }, 3000).fadeOut('slow');
  }
</script>
Notice how pageLoad is now directly inside the <script> block, and no longer between the curly bracec of jQuery's document ready.

Hope this helps,

Imar
