As you see i'm not an expert in javascript. How it should be if the checkbox is dynamic ?

Here is my code:

<form name='teste' method='GET' action='test_resp.jsp' target='bottom'>
<%
ArrayList tt_entLinhas=form.getTT_EntLin(sClienteDef,sReferencia.trim());
    for( int y=0;y<tt_entLinhas.size();y++) 
	  {
        LogiCeasy.TrackTrace.QryEntLin qryEntLin=(LogiCeasy.TrackTrace.QryEntLin) tt_entLinhas.get(y);
out.println("<tr><td><input type='checkbox' name='test' value=" + qryEntLin.getE4lig() + " checked></td><td>" + qryEntLin.getE4art() + 
"</td><td>" + qryEntLin.getE4lig() + 
"</td><td align=center>" + qryEntLin.getE4qapp() + "");
out.println("</td></tr>");
}
%>
<tr align=left><th colspan=4><button id='check' class="submit">Completa</button>&nbsp;<button id='uncheck' onclick='uncheckAll(this.form)' class="submit">Parcial</button></th></tr>
<center>
<tr><td colspan='4' align='left'>
<input type="submit" value="Submeter" class="formButton">

Thanks

I didn't put, but is before the code i wrote.
Your code works if the checkbox is static. Where do i put if it's dynamic ?

<script type='text/javascript'><!-- 
function checkAll(form) { 
  setCheckedState(form, true); 
} 

function uncheckAll(form) { 
  setCheckedState(form, false); 
} 

//--> 
</script>
<form name='teste' method='GET' action='test_resp.jsp' target='bottom'>
<%
ArrayList tt_entLinhas=form.getTT_EntLin(sClienteDef,sReferencia.trim());
    for( int y=0;y<tt_entLinhas.size();y++) 
      {
        LogiCeasy.TrackTrace.QryEntLin qryEntLin=(LogiCeasy.TrackTrace.QryEntLin) tt_entLinhas.get(y);
out.println("<tr><td><input type='checkbox' name='test' value=" + qryEntLin.getE4lig() + " checked></td><td>" + qryEntLin.getE4art() + 
"</td><td>" + qryEntLin.getE4lig() + 
"</td><td align=center>" + qryEntLin.getE4qapp() + "");
out.println("</td></tr>");
}
%>
<tr align=left><th colspan=4><button id='check' class="submit">Completa</button>&nbsp;<button id='uncheck' onclick='uncheckAll(this.form)' class="submit">Parcial</button></th></tr>
<center>
<tr><td colspan='4' align='left'>
<input type="submit" value="Submeter" class="formButton">

you will need to loop through each form element, check whether the element is a checkbox, then check to make sure it's not the "Parcial" checkbox, then go from there...

var allElements = myForm.elements;
for ( var i = 0; i < allElements.length; i++ ) {
    if (allElements[i].type == 'checkbox' )
        allElements[i].checked = false;
}

the above code will loop through all elements in a form element stored in the myForm variable. if the element is a checkbox, it will uncheck it.
