control <div>-contents to be displayed by checkboxes

control <div>-contents to be displayed by checkboxes

Hi,

I am trying to write an application where contents shoud be displayed in different <div>-containers according to checkboxes which are checked.

index.html
  1. <form id="target" name="form" method="post" action="">
       <input type="checkbox" name="layer" id="gia">GIA<br>
       <input type="checkbox" name="layer" id="terms">Terms<br>
       <input type="checkbox" name="layer" id="contact">Contact<br>
       <input type="submit" value=" Absenden ">
    </form>

    <div id="content_gia"></div>
    <div id="content_terms"></div>
    <div id="content_contact"></div>








js.js
  1. $(document).ready(function() {

       $('#target').submit(function() {
         var checkbox = document.getElementsByName("layer");
         var file = '';
         var toLoad = '';

         function loadContent() {
           $('#content_'+file).load(toLoad,'',showNewContent());
         }
         function showNewContent() {
           $('#content_'+file).fadeIn('normal',hideLoader());
         }
         function hideLoader() {
           $('#load').fadeOut('normal');
         }

         for(var i=0; i < checkbox.length; i++) {
           var file = checkbox[i].id;

           if(checkbox[i].checked == true) {
             var toLoad = file+'.php'+' #content';

             $('#content_'+file).fadeOut('fast');  
             $('#load').remove();
             $('#wrapper').append('<span id="load">LOADING...</span>');
             $('#load').fadeIn('normal');

             $('#content_'+file).load(toLoad,'',showNewContent());
           } else {
             $('#content_'+file).fadeOut('fast');
           }
         }

        return false; 
      });
    });




































The problem is:
When I ckeck a checkbox and submit, the content (a new php-page) is loaded and displayed in the appropriate <div>-container.
But when I submit once again, first the old content of the external php-page is fading in. After the external page if fully loaded the correct content shous up and get replaced.

Any idea what I'm doing wrong?

Thanks a lot,
Jozef
