{
$ ("# Country"). get (0). attachEvent ("onpropertychange", function (o ){
Var countr = o. srcElement. value;
$ ("# Tabb1"). hide ();
$. Ajax ({
Type: "post ",
Url: "/yoblhtjfx/queryCountryAjax. action ",
Data: "country =" + countr + "& jsoncallback =? ",
DataType: "json ",
Success: function (json)
{
Var tableHTML;
TableHTML + = "<table id = 'tabb1 'border = '1' width = '000000'> ";
TableHTML + = "<tr> ";
TableHTML + = "<td style = 'text-align: Center'> select </td> ";
TableHTML + = "<td style = 'text-align: Center'> area code </td> ";
TableHTML + = "<td style = 'text-align: Center'> country name </td> ";
TableHTML + = "</tr> ";
Var list = json. list;
For (var I = 0; I <list. length; I ++)

TableHTML + = "</tr> ";
}
TableHTML + = "</table> ";
$ ("# Querycountrydiv" ).html (tableHTML );
}
});
});
}
});
