我有这个用于发送post和pull数据的json代码（参见下文）
$.ajax({
url: '/employee-attendance-history' ,
data: { id : $(this).attr("data-id") },
type: 'post',
dataType: 'json',
success: function(response){
if(response.success){
console.log(JSON.stringify(response.emp_logs));
$.each(response.emp_logs, function(index, value){
alert(value.actual_time);
});
}
}
});
我有这个json回复

我循环了json的回应并试图提醒＆＃34; actual_time＆＃34; value（value.actual_time）但有些人返回我＆＃34; undefined＆＃34 ;,有些人返回我＆＃34; - ＆＃34;有些人给我一个时间戳，任何想法为什么它返回undefined？
