Failed to load resource: the server responded with a status of 500 (Internal Server Error)

第一种情况：sql误写成了day_use_sql 所以报错： POST http:// 500 (Internal Server Error)
第二种情况： 标题中的错误是因为
对数据库的操作中少写了一个 var arr=[];
所以在这里mysql.preQuery(sql, arr, callback);会出现错误
总之500都是服务器内部错误，检查对数据库操作的文件。
if (data.dayTime && data.dayTime != '') {
if(flag) {
day_use_sql += " and Date_Time = ? ";
}else {
day_use_sql += " where Date_Time = ? ";
flag = true;
}
arr.push(data.dayTime);
