Answer 1

您错过了印刷品的括号。

print (np.concatenate(arr1, arr2), axis = 0)

应该是

print (np.concatenate((arr1, arr2), axis = 0))

Answer 2

您正在尝试在null上使用seturi（）。

您仅检查是否有一个称为“服务详细信息操作”的侧栏元素 - 但是，如果“服务详细措施”，“登录到cpanel”或“登录到Webmail”不存在，则您正在尝试设置URI对于不存在的副本子元素。

这很可能与WHMCS更改Menuitems在8.4.1中的工作方式有关： https://docs.whmcs.com/changelog:whmcs_v8.4#maintance_4

core -17437-防止声明错误与菜单项有关
也称为：core-17436

新名称是“ Cpanel”和“ Webmail”，而不是“登录到Cpanel”和“登录到WebMail”。
为了避免抛出例外，您应该检查Menuitem是否存在。

Answer 3

我使用module.export =“ value”获取我想要的数据。我在index.js中进行了此操作，需要索引。

const datas = require("./index.js")
const client = datas.Client

Answer 4

1. 是的，A 简单关联将是正确的选择。无论如何，这是一个共享聚合，它没有定义的语义。参见p。 UML 2.5的110：

表示该属性已共享聚合语义。共享聚合的精确语义因应用区域和建模者而异。

因此，您最好询问图表作者有关他的意图。

2. 这不是依赖性，而是关联。依赖性将用虚线呈现。导航性（使您认为这是一种依赖性的箭头权利）是少量用途。它表明OrderDetail可以看到item，但反之亦然。最好仅在一侧使用角色名称来表达这一事实。例如，仅在右侧放置item，而左侧没有任何内容。

我们能学到什么？ UML是关于沟通的！

Answer 5

时钟周期5-7在您的桌子上不正确。这是正确的表：

Clk  State
1    IDLE
2    SETUP
3    ACCESS
4    ACCESS 
5    ACCESS
6    IDLE
7    SETUP
8    ACCESS
9    ACCESS

5仍然处于访问状态，因为PSEL和PENABLE仍然是1。6

处于空闲状态，因为PSEL和PENABLE为0。第1个APB传输在第5周期中完成。7

是2nd的开始APB传输，这是设置状态。

可以从访问设置过渡，但这将需要PSEL保留1。这将是背对背的转移（转移之间没有空闲）。您的波形并未显示这种情况。但是，背靠背的转移看起来像这样：

            1   2   3   4   5   6   7   8   9
           _   _   _   _   _   _   _   _   _

我不知道他为什么没有将其作为答案，但是您可以做Dean Flinter所说的话：

SELECT pid
       ,LISTAGG(DISTINCT acc_no, ',') WITHIN GROUP(ORDER BY acc_no) 
        AS acc_no_txt
FROM
(SELECT pid
      ,CASE WHEN acc_no_v01 IN ('not found','blank','nil-value','',' ','null') THEN NULL
       ELSE acc_no_v01
       END
       AS acc_no
      ,MIN(TRY_TO_NUMBER(T2.vp_no)) AS vp_no
FROM table_1 T1
JOIN table_2 T2
ON T2.click_stream_integration_id = T1.click_stream_integration_id
WHERE T2.date = '2022-01-01'
AND pid='123456789'
GROUP BY pid,acc_no_v01
ORDER BY TRY_TO_NUMBER(vp_no)
)
GROUP BY pid;

Answer 7

scroll-behavior css属性元素顺利滚动。
element.scrollintoview 用于程序上卷轴滚动一个元素。

如果您想滚动到页面的标题 scroll-behavior：smooth您可以选择行为选项并设置它到平滑。

var header = document.getElementById("header")
header.scrollIntoView({ behavior: "smooth" })

Answer 8

您可以尝试使用给定的2种方法。

1。

<form #f="ngForm" (ngSubmit)="submit(f)">
  <div class="form-group">
    <label for="firstname">Name </label><br />
    <input
      type="text"
      class="form-control"
      name="firstname"
      [(ngModel)]="employee.firstname"
    />
  </div>
  <button class="btn" type="submit">Update Employee Name</button>
</form>

<form #f="ngForm" (ngSubmit)="submit(f)">
  <div class="form-group">
    <label for="firstname">Name </label><br />
    <input

您不显示代码，但我想您使用scrollview。您可以尝试添加参数：physics = NeverScrollablesCrollphysics（）， to ListView Widget。

这是我想到的，它对其他人可能很有用 - 将ACSII转换为十进制，创建AudioBuffer，这是ASCII/DICMAL的长度，映射值-1和1之间的小数-1和1之间，将结果放入AudioBuffer中并播放。一旦您知道要寻找什么（我完全没有）就不复杂。

Answer 11

我认为您想更改

$teachername = implode(",",$teachername);
$submittedby = implode(",",$submittedby);
$item = implode(",",$item);
$description = implode(",",$description);
$quantity = implode(",",$quantity);
$vendor = implode(",",$vendor);
$notes = implode(",",$notes);

$count = 1;

$insertquery = "INSERT INTO orderinfo(teachername,submittedby,item,description,quantity,vendor,notes) VALUES('".$teachername."','".$submittedby."','".$item."','".$description."','".$quantity."','".$vendor."','".$notes."')";
mysqli_query($con,$insertquery);

为

$teachername = implode(",",$teachername);
$submittedby = implode(",",$submittedby);
$notes = implode(",",$notes);
for ($i = 0; $i <= count($item); $i++) {
    $curItem = $item[$i];
    $curDescription = $description[$i];
    $curQuantity = $quantity[$i];
    $curVendor = $vendor[$i];

    $insertquery = "INSERT INTO orderinfo(teachername,submittedby,item,description,quantity,vendor,notes) VALUES('".$teachername."','".$submittedby."','".$curItem."','".$curDescription."','".$curQuantity."','".$curVendor."','".$notes."')";
    mysqli_query($con,$insertquery);
}

，以便为每个$ item，您将新行插入数据库。

Answer 15

我认为这个问题的快速解决方法可能是使用lodash的_。uniqby（） method（ https://lodash.com/docs/4.17.15#uniqby ）。这将为您提供19个重新加载的19个显示，但至少可以确保您没有任何重复的项目。

我认为真正的解决方案是弄清楚为什么API返回第10个项目两次。在尝试从数据库中获取原始查询时，起始值似乎可能是不正确的。

使用Burp Suite并与代理拦截器一起玩，看起来查询最终看起来像这样的东西：/api/cratce？locale = en＆amp; populate =*＆amp;分页[start] = 10＆amp;分页[limit] = 10＆amp; sort [0] = date％3ADESC。我认为，如果您碰到分页[启动] 1，那应该实际上可以解决您的问题。至少对我做了。
