Can anyone please help correct some Javascipt? This particular script is not in the download.... it is in Chapter 11.

When I run the script, I get:

Error: '$' is undefined in the browser. (How can it be undefined??)

The code is below and seems identical to the code in the book - but I am willing to bet it has a glitch I have not found yet.

Code:

<%--Java Script to apply Watermark --%>
<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');
     });
</script>

Hi there,

The error "Error: '$' is undefined in the browser." seems to imply the jQuery library cannot be found. Did you add a reference to it in your page or master page? Can you show the code for that and describe where you placed the jQuery library .js file?

Cheers,

Imar

Thanks you are quite right, no reference. I was trying to test my understanding by putting subjects in the book into my own web site - and I missed an important step.
