//e.prevendDefault();
var ansSeg = m.children("div").children('#txtSeguimiento');
var orden = m.children("div").children('#hdnOrden');
if (ansSeg.val() != "") {
jQuery.post('/ajsources/callCenterXml.php', {'sg': ansSeg.val(),'q': orden.val(),'nty': 'addSeg', 'a': anio});
}
if ($("#hdnDialog").val() === "1") {
verSeguimiento2(orden.val().substring(6), anio);
