Question

Hi,

I'm new at javascript. I'm looking for help with the code below. I am trying to create a nav bar with opening and closing divs (vertical tab menu). However I'd like to have the ability for the user not to have to close the div in order to select the next div. Is there any action i can add to the code below to enable this function? Thank you.

<script type="text/javascript">
function unhide(divID) {
  var item = document.getElementById(divID);
  if (item) {
    item.className=(item.className=='hidden')?'unhidden':'hidden';
  }
}*/
</script> 


<div id="FabNav">

    <div id="fb-tab" class="tab-header"><a href="javascript:unhide('fb-description');" class="button">Dropdown One</a></div>
    <div id="fb-description" class="hidden">
        <table width="512px" border="1" bordercolor="#666666" cellspacing="0" cellpadding="0">
          <tr>
            <td>

</div>

    <div id="fb-tab" class="tab-header"><a href="javascript:unhide('fb-description');" class="button">Dropdown Two</a></div>
    <div id="fb-description" class="hidden">
        <table width="512px" border="1" bordercolor="#666666" cellspacing="0" cellpadding="0">
          <tr>
            <td>

</div>

</div>

go over to my coding examples at:
http://www.datacorner.com/coding/doCallTime.txt

look for the getObj function...is a cross-browser version of your document.getElementById. getObj will return the element reference.

Then look for the showDbg and hideDbg functions. Given a valid element reference, they show you how to modify the style parameter to make elements visible or hidden.

Or you could also try this:

   var ua = ((( ie = document.all[ divID ] ) && !!!( ff = document.getElementById( divID ))) ? 1 : 0 ); 
   var item = null || { 0 : ff, 1 : ie }[ ua ];
   var saved = 0 || save[ 0 ];
   if ( saved && saved.id === item.id ) {
      return false; 
   } else {

      } item.className = (( item.className !== "unhidden" ) ? "unhidden" : "hidden" );

Thanks for you both for your help!

One more thing. The code you supplied is almost what I'm looking. Leaving is just as it is, can we add the functionality of having the clicked div collapsible as well?

I'm creating a page the will always show with a tab nav bar to the right, which I'd like to show and hide the tabs but have the functionality that if the user selects another tab in the nav bar the other will close but also be able to be close as well - so the the main page is viewable. I tried to word this as clearly as I can. Thanks again!

Another way to achieve the same effect without using CSS is to do
item.style.display = 'none'; // Hides
or
item.style.display = ''; // Shows

you can get the collapse effect with jquery or any other library for that matter. That would be the easiest.
To get the effect so it will close the other tabs you could just add
document.getElementById(divID).style.display = 'none';
to the trigger function and add the id for each item.

Hi socalfoolina,

here's your requested script, that comes with a pretty basic lines that you can easliy expand and use. With No fancy statements on it...

Here's the code:

        padding : 0;
      }
      .unhidden { 
        display : block;
      }
      .hidden { 
        display : none;
      }
      -->
      </style>
      <script type="text/javascript">
      <!--
      var save = ( [] );
      var unhide = ( function( divID ) {

      if ( divID ) {
        (( item = document.getElementById( divID )) ? ie = 0 : item = document.all[ divID ] );
      if ( save[ 0 ] && save[ 0 ].id !== String ( item.parentNode.id )) {
         var isParent = save[ 0 ].parentNode;
         var node = isParent.childNodes;
         var nType;
         for ( i = 0; i < node.length; i++ ) {
         nType = node[ i ].nodeType;
            if ( nType === 1 || nType === Node.ELEMENT_NODE ) {
               if ( node[ i ].hasAttribute( "class" )) {
                  node[ i ].className = "hidden";
                  continue;
               }
