I have a menu of tabs that as you select the tabs changes the content.
Flaps change:
<script language="JavaScript">
function stAba(menu,conteudo)
{
this.menu = menu;
this.conteudo = conteudo;
}
var arAbas = new Array();
arAbas[0] = new stAba('td_usua','div_usua');
arAbas[1] = new stAba('td_empr','div_empr');
arAbas[2] = new stAba('td_nota','div_nota');
arAbas[3] = new stAba('td_soft','div_soft');
function AlternarAbas(menu,conteudo)
{
for (i=0;i<arAbas.length;i++)
{
m = document.getElementById(arAbas[i].menu);
m.className = 'menu';
c = document.getElementById(arAbas[i].conteudo)
c.style.display = 'none';
}
m = document.getElementById(menu)
m.className = 'menu-sel';
c = document.getElementById(conteudo)
c.style.display = '';
}
</script>
My question is: "How to clear data from previous tab when selecting another tab?"
Menu image: 
I call the AlternarAbas() in the menu where the desired option is chosen:
<body onLoad="AlternarAbas('td_usua','div_usua')">
<table width="945" height="50" align="left" valign="top" cellspacing="0" cellpadding="5" border="0" style="border-left: 1px solid #000000;" >
<tr>
<td height="20" width="50" class="menu" id="td_usua" onClick="AlternarAbas('td_usua','div_usua')">Usuario</td>
<td height="20" width="50" class="menu" id="td_empr" onClick="AlternarAbas('td_empr','div_empr')">Empresa</td>
<td height="20" width="50" class="menu" id="td_nota" onClick="AlternarAbas('td_nota','div_nota')">Nota Fiscal</td>
<td height="20" width="50" class="menu" id="td_soft" onClick="AlternarAbas('td_soft','div_soft')">Software</td>
</tr>
The data to which I refer are the ones that the user types. That is, if the user type something in the area of incluir do Usuário and then change to Empresa, the data he reported on incluir will disappear!

Works if called by an iframe?
<tr>
<td height="300" width="" class="tb-conteudo" colspan="4" align="left" valign="top" >
<div id="div_usua" class="conteudo" style="display: none; padding-top:5px;">
<table align="left" border="0" width="2%">
<tr>
<td>
<iframe style="border-radius:20px;" scrolling="no" src="../sai_cada_usua/menu_com_abas_usua.php" width="900" height="400 " >
</iframe>
</td>
</tr>
</table>
</div>
</td>
</tr>
Thanks for the help @Zuul was exactly why I was looking for! Even not working on my code, I decode it to implement. But that’s the idea I wanted ^^
