return false;
}
alert($("input[type=radio]:checked").val());

var values = "";
$("input[name='chkSelect']").each(function () {
if ($(this).attr("checked")) {
values += $(this).val() + ",";
}
});
if (values == "") {
alert("请选择");
return false;
}
values = values.substring(0, values.length - 1); //去掉尾部,
alert(values);

$("input[name='chkSelect']").each(function () {
$(this).attr("checked", true);
