小编Giu*_*ini的帖子

我有一张CLIENTS这样的桌子：

------------------------------------------------
| ID |  Name     |   Surname   |    Company    |
------------------------------------------------
|  1 |  John     |      Doe    |               |
------------------------------------------------
|  2 |           |             |     Company 1 |
------------------------------------------------
|  3 |   Mark    |   Blue      |     Company 2 |
------------------------------------------------
|  4 |           |             |     Company 3 |
------------------------------------------------
|  5 |     Jim   |   Yellow    |               |

实际上，我有一个返回结果的脚本PHP SELECT * FROM CLIENTS ORDER BY Company ASC。按字母顺序检索结果

结果插入（供查看）在表中，其中column NAME or COMPANY是Company（如果已编译）或Surname + Name …

我的in_array功能有问题.

这是我的array:键可以是字符串或int的混合,就像这个例子.

<?php

$array = array(
    "a" => true,
    "b" => true,
    "c" => true,
    "d" => true,
    0 => "Code",
    1 => "Time",
    2 => "Other"
);

var_dump($array);

if ( in_array("Test", $array) ) { echo "found"; }

此代码打印始终found.

为什么？

我从jj调用返回这个json:

{"datasets":[
    {"data":[0,0,2,0,1,0,0,0,0,0,5,2], "service_ID": 1},
    {"data":[0,0,0,0,0,0,0,0,0,0,1,3], "service_ID": 2},
    {"data":[0,0,0,0,0,0,0,0,0,0,0,2], "service_ID": 3},
    {"data":[0,0,0,0,0,0,0,0,0,0,0,4], "service_ID": 4},
    {"data":[0,0,0,0,0,0,0,0,0,0,0,1], "service_ID": 5}
   ]
}

data对象内的每个元素都是一月份的值,从1月到12月(12个元素的数组)

我需要循环内部datasets以获取data对象内的每个值并获得总和,在此示例中:2+1+5+2+1+3+2+4+1 = 21

我试过了

var total = 0;

          $.each(datasets, function(index, data) {
                $.each(data, function(index, month) {
                    $.each(month, function(index, value) {
                        total = total + value;
                    });
                });
          });

但我得到TypeError: invalid 'in' operand a错误.

得到我需要的最好的方法是什么？
