How should I modify it in order to let it run successfully in Netscape?

 

by: pocarPosted on 2002-09-09 at 05:29:28ID: 7272137

This works in IE5 and Mozilla 1.0 (NS6+), for NS4 I have no clue (probably you should use layers):

<script language="JavaScript" type="text/javascript">
    <!--
    function JsMenuBar(jsId) {
         for (jsCounter=1;jsCounter<3;jsCounter++) {
              //eval("item"+jsCounter).style.display="none";
              document.getElementById('item'+jsCounter).style.display = 'none';
         }

         //jsId.style.display="block";
           document.getElementById(jsId).style.display = 'block';
    }
    //-->
</script>
</head>
<script language="JavaScript">
    <!--
    function JsMenuBar(jsId) {
         for (jsCounter=1;jsCounter<3;jsCounter++) {
              //eval("item"+jsCounter).style.display="none";
                 document.getElementById('item'+jsCounter).style.display = 'none';
         }

         //jsId.style.display="block";
           document.getElementById(jsId).style.display = 'block';
    }
    //-->
</script>
</head>
<body bgcolor="#FFFFFF" text="#000000" topmargin="0" leftmargin="0">
<table width="100%" cellspacing="0" cellpading="0" border="0">
    <tr><td>
         <table><tr>
           <td width="50">&nbsp;</td>
         <td width="100" align="center" bgcolor="#009900" style="cursor:pointer" onclick="JsMenuBar('item1');return true">Tab 1</td>
         <td width="10">&nbsp;</td>
         <td width="100" align="center" bgcolor="#FF9900" style="cursor:pointer" onclick="JsMenuBar('item2');return true">Tab 2</td>
         <td>&nbsp;</td></tr>
           </table>
           </td>
    </tr>
    <tr id="item1" style="display:block">
         <td width="100%" bgcolor="#009900">Contents of Tab 1</td>
    </tr><tr id="item2" style="display:none">
          <td width="100%" bgcolor="#FF9900">Contents of Tab 2</td>
    </tr>
</table>
</body>

Btw, In this case I would rather use layers (<div> tag), because their are much easier to deal with.

 

by: pocarPosted on 2002-09-09 at 05:57:24ID: 7272189

Now I see, that Mozilla couses some traubles, so there is one working example using layers. You just have to set top position of layers (in % or px). If top position of layers not know at design time, then change <div></div> to <span></span> and set left position. And make sure that you will set margins of page (different browsers use different).
And instead of 'display' is 'visibility' (NS4 use <layer> insted of <div> accessed by document.layers[...] and instead of 'hidden' is 'hide' - but never use that and neither have that browser on my system):

<script language="JavaScript">
    <!--
    function JsMenuBar(jsId) {
         for (jsCounter=1;jsCounter<3;jsCounter++) {
              //eval("item"+jsCounter).style.display="none";
                 document.getElementById('item'+jsCounter).style.visibility = 'hidden';
         }

         //jsId.style.display="block";
           document.getElementById(jsId).style.visibility = '';
    }
    //-->
</script>
</head>
<body bgcolor="#FFFFFF" text="#000000" topmargin="0" leftmargin="0">
<table width="100%" cellspacing="0">
    <tr><td>
         <table><tr>
           <td width="50">&nbsp;</td>
         <td width="100" align="center" bgcolor="#009900" style="cursor:pointer" onclick="JsMenuBar('item1');return true">Tab 1</td>
         <td width="10">&nbsp;</td>
         <td width="100" align="center" bgcolor="#FF9900" style="cursor:pointer" onclick="JsMenuBar('item2');return true">Tab 2</td>
         <td>&nbsp;</td></tr>
           </table>
           </td>
    </tr>
    <tr><td>
         <div id="item1" style="width:100%; background-color:#009900; position:absolute; top:28px;">Contents of Tab 1</div>
          <div id="item2" style="width:100%; background-color:#FF9900; position:absolute; top:28px; visibility: hidden">Contents of Tab 2</div>
    </td></tr>
</table>
