จากบทความนี้ อยากประยุกให้ กำสามาถใช้กับ input type number ได้ไหมครับ

<input type=text name=budget >
<input type=number name=used min=1 max='10000' 
     onfocus="this.setAttrbute('max', document.formname.budget.value)">

            //*** Column Budget ***//
            newCell = newRow.insertCell(5);
            newCell.id = newCell.uniqueID;
            newCell.setAttribute("className", "css-name");
            newCell.innerHTML = "<center><INPUT TYPE=\"TEXT\" SIZE=\"30\" NAME=\"txtBudget_" + intLine + "\"  ID=\"txtBudget_" + intLine + "\" VALUE=\"\"></center>";

            //*** Column Used ***//
            newCell = newRow.insertCell(6);
            newCell.id = newCell.uniqueID;
            newCell.setAttribute("className", "css-name");
            newCell.innerHTML = "<center><INPUT TYPE=\"NUMBER\" SIZE=\"30\" min=\"1\" onfocus=\"this.setAttrbute('max', document.frmMain.txtBudget_" + intLine + "\".value)\" NAME=\"txtUsed_" + intLine + "\"  ID=\"txtUsed_" + intLine + "\" VALUE=\"\"></center>";

function set_max( obj, intLine ){
   var mx = parseInt( '0' + document.getElementById('txtBudget_'+intLine).value);
   if( mx==0) mx = 10000; // กำหนดค่า default
   obj.setAttribute('max', mx);
}

newCell.innerHTML = '<center><input type=number size=30 min=1 data-lineNo='+intLine+
     ' onfocus="set_max(this)" name=txtUsed_' + intLine + ' id=txtUsed_'+intLine+' ></center>';
