Question

我的mysql数据库中有各种产品的数据。实施例

ID    Name     price    detail    fact
1     test     20.00    text      example
2     testing  30.00    apple     orange
3     tester    5.43    plum      grape

我有类似下面的html代码然后重复让我们说大约30个不同的时间因为mysql中有30个不同的产品数据

                                    <li><a href=""><i class="fa fa-plus-square"></i>Add to compare</a></li>
                                </ul>
                            </div>
                        </div>

我想要完成的是例如，在产品1代码中输入“price 1”将是我的数据库第一行中价格的变量，“detail 1”将是来自产品1的第一行详细信息数据库。所以第四个。然后，当我们到达产品2代码时，跳到第二行数据并在其正确的字段中插入匹配数据。并重复此过程，直到数据库中的所有产品都与代码匹配。另请注意，并非所有mysql数据行中的字段都被用作“事实”，例如。

我不知道如何做到这一点。

您需要通过查询MySQL数据库来获取数据。完成此操作后，您可以逐行遍历结果集并输出。

module.exports = Promise.all(dep.map(function(name) {
    distance.departure_time(name);
    return getMatrix(distance, origins, destinations).then(function(distances) {
        if (!distances) throw new Error('no distances');
        var promises = [];
        if (distances.status == 'OK') {
            for (var i=0; i < origins.length; i++) {
                for (var j = 0; j < destinations.length; j++) {
                    var origin = distances.origin_addresses[i];
                    var destination = distances.destination_addresses[j];
                    if (distances.rows[0].elements[j].status == 'OK') {
                        var duration = distances.rows[i].elements[j].duration_in_traffic.value;
                        var myobj = {
                            destination: destination,
                            departure_time: name,
                            duration: duration
                        };
                        var str = destination.replace(/[,\s]+/g, '');
                        promises.push(save(url, myobj, str));
//                                    ^^^^^^^^^^^^^^^^^^^^^
                    }
                }
            }
        }
        return Promise.all(promises); // now wait for all save results
    });
}));

使用来自mysql数据库的php填充多个变量
