我还需要这样做 - 就我而言,参考 observableCollection< state>状态来自多个页面。将其作为另一个可能的解决方案共享:

我创建了一个使用 observableCollection 作为 static> static 成员的类,该成员首次使用:

public class Filter
{
    ...
    public static ObservableCollection<State> StateSelections { get; } = new();
    ...
    public Filter(DataService dataService) : base()
    {
        this.dataService = dataService;

        PopulateData();
    }

    public async Task PopulateData()
    {
        // Populate the available selections
        await LoadStates();
    }

    public async Task LoadStates()
    {
        if (StateSelections?.Count > 0)
            return;
        ...
    }
}

对于使用集合的每个页面,其VM具有对类的实例的引用:

public partial class ParkListVM : BaseVM
{
    ...
    public Filter Filter { get; set; }
    ...

    public void PopulateData()
    {
        if (ParkListVM.Filter is null)
            ParkListVM.Filter = new Filter(dataService);
        ...
    }
}

该页面对显示静态集合的引用:

<ContentPage
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:vm="clr-namespace:NationalParks.ViewModels"
    xmlns:model="clr-namespace:NationalParks.Models"
    x:DataType="vm:ParkListVM"
    x:Class="NationalParks.Views.ParkListPage"
    Title="{Binding Title}">
    <ContentPage.Resources>
        <model:Filter x:Key="Filter"/>
    </ContentPage.Resources>
    ...
    <CollectionView ItemsSource="{Binding Source={x:Static model:Filter.StateSelections}}"
                    SelectionMode="Multiple"
                    SelectedItems="{Binding SelectedStates}">
        <CollectionView.ItemTemplate>
            <DataTemplate x:DataType="model:State">
                <VerticalStackLayout>
                    <Label Style="{StaticResource LabelMedium}" Text="{Binding Name}" />
                </VerticalStackLayout>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>
    ...
</ContentPage>

I had need to also do this -- in my case, reference an ObservableCollection<State> States from multiple pages. Sharing this as another possible solution:

I created a class with the ObservableCollection as a static member which is populated once upon first use:

public class Filter
{
    ...
    public static ObservableCollection<State> StateSelections { get; } = new();
    ...
    public Filter(DataService dataService) : base()
    {
        this.dataService = dataService;

        PopulateData();
    }

    public async Task PopulateData()
    {
        // Populate the available selections
        await LoadStates();
    }

    public async Task LoadStates()
    {
        if (StateSelections?.Count > 0)
            return;
        ...
    }
}

For each page that uses the collection, its VM has a reference to an instance of the class:

public partial class ParkListVM : BaseVM
{
    ...
    public Filter Filter { get; set; }
    ...

    public void PopulateData()
    {
        if (ParkListVM.Filter is null)
            ParkListVM.Filter = new Filter(dataService);
        ...
    }
}

And the page has a reference to the static collection for display:

<ContentPage
    xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
    xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
    xmlns:vm="clr-namespace:NationalParks.ViewModels"
    xmlns:model="clr-namespace:NationalParks.Models"
    x:DataType="vm:ParkListVM"
    x:Class="NationalParks.Views.ParkListPage"
    Title="{Binding Title}">
    <ContentPage.Resources>
        <model:Filter x:Key="Filter"/>
    </ContentPage.Resources>
    ...
    <CollectionView ItemsSource="{Binding Source={x:Static model:Filter.StateSelections}}"
                    SelectionMode="Multiple"
                    SelectedItems="{Binding SelectedStates}">
        <CollectionView.ItemTemplate>
            <DataTemplate x:DataType="model:State">
                <VerticalStackLayout>
                    <Label Style="{StaticResource LabelMedium}" Text="{Binding Name}" />
                </VerticalStackLayout>
            </DataTemplate>
        </CollectionView.ItemTemplate>
    </CollectionView>
    ...
</ContentPage>

.NET MAUI:如何从任何内容页面(MVVM)中读取/写入(获取/设置)一个全局对象

暮年慕年 2025-02-20 23:41:18

听起来好像是下颌虚拟光标已关闭。尝试按下插入+z,并应宣布“下巴虚拟光标”,然后尝试再次箭头。

It sounds as though the JAWS virtual cursor has been turned off. Try pressing Insert+Z and it should announce "JAWS virtual cursor on", then try arrowing again.

JAWS屏幕读取器用箭头键向上/向上滚动Firefox页面,而不是在元素之间导航

为了添加已经提供的答案,差异不是操作员(如您在问题中所提到的那样),而是语法。这很重要,因为 ... x 不会产生像操作员这样的值独立 - 需要在某些上下文中使用,例如数组 [... x] 或对象 {... x} 。安德鲁·李(Andrew Li)在

因此,尽管它们看起来相同,但 ... x 的行为和运行时语义取决于上下文(即使用的位置)。实际上,正如尼克正确地指出的那样,在他们的答案,对象传播/扩散属性 {... x} 和数组差<代码> [... x] 在两个完全独立的版本的ecmascript(js)规范中添加Ecmascript2018和阵列传播在Ecmascript2015(又名ES6)中引入。


spread属性 {... x}

当我们在对象中使用vrair语法字面 {... x} 时,要求是指向右 - ... 的手侧(即: x )评估对象或可以转换为对象的东西( null 未定义的)。然后,将该对象的(枚举自己的)属性复制到我们创建的对象文字 {} 中。当您最终这样做时:

{...false}

JavaScript看到 false 不是对象(它是原始的),因此它通过将其包裹在布尔对象中来将其转换为一个对象:

{...new Boolean(false))}

因为 new Boolean(false) 没有任何可以实现的属性,我们创建的新对象 {} 没有将任何属性复制到其中,因此您最终会得到一个空对象。


数组差<代码> [... x] :

使用 ... x (spriz element)在数组 [... x] 与上面描述的范围属性 {... x} 相比,运行其他用于传播行为的算法。

随着数组的蔓延,要求是表达式到 ... 的右侧,将评估对某些内容。

在这种情况下,如果它是一个具有属性/众所周知的符号的对象 符号>符号 在其上定义的调用,返回 ... [] ,因此您的第二个示例为什么使用 true&amp;&amp; ['bar'] 。 该数组正在使用。

迭代器产生的每个值都添加到新创建的数组中, 诸如 false 之类的效果,在您的示例中,JS无法迭代它,因此您会得到typeError。

To add to the already provided answers, spread is not an operator (as you've mentioned in your question), but rather, it is a syntax. This matters because ...x doesn't produce a value like operators such as + and - do, and it can't be used standalone - it needs to be used in certain contexts, such as in arrays [...x] or objects {...x}. Andrew Li goes into great detail about this in his great answer.

So while they look the same, the behaviour and runtime semantics of ...x depends on the context (ie: where it's being used). In fact, as Nick rightly points out in their answer, object spread/spread properties {...x} and array spread [...x] were added in two completely separate versions of the ECMAScript (JS) specification (spread properties being introduced in ECMAScript2018 and array spread being introduced in ECMAScript2015, aka ES6).


Spread properties {...x}:

When we use the spread syntax in an object literal {...x}, the requirement is that the expression to the right-hand side of the ... (ie: x) evaluates to an object or to something that can be converted to an object (with exceptions for null and undefined). The (enumerable own) properties of this object are then copied into the object literal {} we're creating. When you end up doing:

{...false}

JavaScript sees that false is not an object (it's a primitive), so it converts it to one by wrapping it in a boolean object:

{...new Boolean(false))}

Since new Boolean(false) doesn't have any own-enumerable properties, the new object we're creating {} doesn't get any properties copied into it, so you end up with an empty object.


Array spread [...x]:

Using ...x (spread element) in the context of an array [...x] runs a different algorithm for spreading behavior compared to the one described above for spread properties {...x}.

With array spread, the requirement is that the expression to the right-hand side of the ... evaluates to something iterable.

In this context, something is iterable if it's an object that has the property/well-known symbol of Symbol.iterator defined on it that when invoked, returns an iterator. Arrays natively have this symbol which is why we can use ...[] on them in the context of arrays, hence why your second example works with true && ['bar']. Each value that the iterator produces is added to the newly created array that the spread syntax is being used in.

When x in [...x] evaluates to something non-iterable such as false in your example, JS is unable to iterate it, and so you get a TypeError.

JavaScript传播操作员和有条件,为什么它不适合数组?

您是否尝试应用 requestformlimits 属性并设置 multipartbodyLengthllimit ,如下吗?

[RequestFormLimits(MultipartBodyLengthLimit = 6104857600)] 
public async Task<IActionResult> UploadFile(IFormFile file, int id)
{
    // your core here...
}

另外,如果您是在IIS Set MaxallowedContentLength 参数下 web.config 中的参数。对于ASP.NET Core MVC项目,此文件并未自动添加,但是IIS仍然需要手动添加。

<system.webServer>
    <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="4147483648" /> 
      </requestFiltering>
    </security>
    ...
</system.webServer>

通过 参数通过 startup.cs 文件:

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<FormOptions>(o =>
    {
        o.ValueLengthLimit = int.MaxValue;
        o.MultipartBodyLengthLimit = long.MaxValue; 
    });

    services.AddControllersWithViews();
}

Did you try to apply RequestFormLimits attribute and set the MultipartBodyLengthLimit, like below?

[RequestFormLimits(MultipartBodyLengthLimit = 6104857600)] 
public async Task<IActionResult> UploadFile(IFormFile file, int id)
{
    // your core here...
}

In additional, if you are running under the IIS set maxAllowedContentLength parameter in the web.config. For the ASP.NET Core MVC project this file doesn't added automatically, but it still needed for the IIS and should be added manually.

<system.webServer>
    <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="4147483648" /> 
      </requestFiltering>
    </security>
    ...
</system.webServer>

Configuring the FormsOptions parameters through the startup.cs file:

public void ConfigureServices(IServiceCollection services)
{
    services.Configure<FormOptions>(o =>
    {
        o.ValueLengthLimit = int.MaxValue;
        o.MultipartBodyLengthLimit = long.MaxValue; 
    });

    services.AddControllersWithViews();
}

使用 pyspark 。改编自这个答案(spark)

window = Window.partitionBy(['id', 'cod']).orderBy(col('flag').desc())
out = (df.withColumn('row',  row_number().over(window))
         .filter(col('row') == 1).drop('row'))
out.show()

从独木舟版本12.0 SP3

搜索 .net dll 的详细信息以获取 .net dll 以获取详细信息。

基本上,您可以创建一个.NET函数,就像

namespace ns {
  public class Clazz {
    public static Int32 Func(Int32 a) {
      ...
      return a;
    }
  }
}

它必须是静态的,公共的和公共课程一样。
仅允许某些数据类型作为参数并返回值。

必须以与CAPL-DLL相同的方式添加编译的.NET DLL。

然后从CAPL调用该函数,然后看起来像这样:

retVal = ns::Clazz::Func(17);

如果您必须早于12.0 SP3的独木舟版本,则必须在C/C ++中创建CAPL DLL,并通过CLI调用C#代码。

Calling C# (or any other .NET) code is actually possible starting from CANoe version 12.0 SP3

Search for .NET DLL in CANoe's help for details.

Basically, you create a .NET function like

namespace ns {
  public class Clazz {
    public static Int32 Func(Int32 a) {
      ...
      return a;
    }
  }
}

It must be static, public and in a public class.
Only certain datatypes are allowed as parameters and return value.

The compiled .NET DLL has to be added to CANoe in the same way as a CAPL-DLL.

Calling the function from CAPL then looks like this:

retVal = ns::Clazz::Func(17);

If you have to use a CANoe version earlier than 12.0 SP3, you would have to create a CAPL DLL in C/C++ and call you C# code via CLI.

我想在CAPL代码中进行特定函数调用后在C#中执行代码

from scrapy.crawler import CrawlerProcess

class TestSpider(scrapy.Spider):

        e1=e1.get() if e1 else None
        e2=response.xpath('(//*[@class="address_e"])[1]//@data-eb')
        e2=e2.get() if e2 else None
        try:
            data = e1 +'@'+ e2
            yield {
                'status':response.xpath("//span[contains(text(), 'Status:')]/../div/text()").get(),
                'email': data,
                'url':response.url
                }

        except:
            pass
       

if __name__ == "__main__":
    process =CrawlerProcess(TestSpider)
    process.crawl()
    process.start()

此XPath表达式将帮助您拉出所有5行的所有数据

//span[contains(text(), 'Status:')]/../following-sibling::div[1]/div

//span[contains(text(), 'Status:')]/../following-sibling::div[1]/span

Try:

import scrapy
from scrapy.http import Request
from scrapy.crawler import CrawlerProcess

class TestSpider(scrapy.Spider):
    name = 'test'
    start_urls = ['https://rejestradwokatow.pl/adwokat/list/strona/1/sta/2,3,9']

        }


    def parse(self, response):
        books = response.xpath("//td[@class='icon_link']//a//@href").extract()
        for book in books:
            url = response.urljoin(book)
            yield Request(url, callback=self.parse_book)
            
    def parse_book(self, response):
        e1 = response.xpath('(//*[@class="address_e"])[1]//@data-ea')
        e1=e1.get() if e1 else None
        e2=response.xpath('(//*[@class="address_e"])[1]//@data-eb')
        e2=e2.get() if e2 else None
        try:
            data = e1 +'@'+ e2
            yield {
                'status':response.xpath("//span[contains(text(), 'Status:')]/../div/text()").get(),
                'email': data,
                'url':response.url
                }

        except:
            pass
       

if __name__ == "__main__":
    process =CrawlerProcess(TestSpider)
    process.crawl()
    process.start()

This xpath expression will help you to pull all 5 row's all data like

//span[contains(text(), 'Status:')]/../following-sibling::div[1]/div

//span[contains(text(), 'Status:')]/../following-sibling::div[1]/span

robot

the value of robot change when you run setRobot, not when you input something to search for

so yeah, that will result in an infinite loop

另外,如果您不想使用通用性,则联合应该在功能范围之外

type Column = {
  key: string
  label: string
  transformFunc?: 
    ((value: string) => string) | 
    ((value: number) => string) | 
    ((value: Date) => string)
};

const col: Column = {
  key: 'date',
  label: 'Date',
  transformFunc: (value: string) => value.substring(0, 5)
}

,或者要根据TransformFunc的值推断类型,如果您可以使用助手功能,

type ColumnGeneric<T extends string | number | Date> = {
  key: string
  label: string
  transformFunc?: (value: string | number | Date) => string
}

const columnInferenceBuilder = <
  _ extends ColumnGeneric<FunctionProp>, 
  FunctionProp extends string | number | Date
>(o: {
  key: string;
  label: string;
  transformFunc: (value: FunctionProp) => string
}) => o

const inferredColumn = columnInferenceBuilder({
  key: 'date',
  label: 'Date',
  transformFunc: (value: string) => 'foobar',
})

则该模式可能会更有用具有 value 的额外属性,该属性与TransformFunc参数相对应(或以某种方式与与之歧视)

// imagine its imported
const importedData = {
  key: 'foo',
  label: 'Foo',
  value: 0
} as const

const inferredColumn2 = columnInferenceBuilder2({
  ...importedData,
  transformFunc: (value) => 'foobar',
  //   ^? (value: 0) => string
})

Alternatively if you don't want to use a generic, the union should instead be outside of the function scope

type Column = {
  key: string
  label: string
  transformFunc?: 
    ((value: string) => string) | 
    ((value: number) => string) | 
    ((value: Date) => string)
};

const col: Column = {
  key: 'date',
  label: 'Date',
  transformFunc: (value: string) => value.substring(0, 5)
}

Or if you want to infer the type based on the value of transformFunc you can use a helper function

type ColumnGeneric<T extends string | number | Date> = {
  key: string
  label: string
  transformFunc?: (value: string | number | Date) => string
}

const columnInferenceBuilder = <
  _ extends ColumnGeneric<FunctionProp>, 
  FunctionProp extends string | number | Date
>(o: {
  key: string;
  label: string;
  transformFunc: (value: FunctionProp) => string
}) => o

const inferredColumn = columnInferenceBuilder({
  key: 'date',
  label: 'Date',
  transformFunc: (value: string) => 'foobar',
})

This pattern might be more useful if you had an extra property of value that corresponds to the transformFunc arguments (or somehow related otherwise to discriminate with)

// imagine its imported
const importedData = {
  key: 'foo',
  label: 'Foo',
  value: 0
} as const

const inferredColumn2 = columnInferenceBuilder2({
  ...importedData,
  transformFunc: (value) => 'foobar',
  //   ^? (value: 0) => string
})

如果有人看到这个,需要一个答案,我已经弄清楚了

Sub Sendemails()

Dim objOutlook As Outlook.Application
Dim objMail As Outlook.MailItem
Dim signature As Variant
Dim rngemailaddress, Emailaddress As Range
Dim numberofrows As Long


numberofrows = Sheet1.Range("A100000").End(xlUp).Row

Set rngemailaddress = Range("A1:A" & numberofrows)
For Each Emailaddress In rngemailaddress.Cells
Set objOutlook = Outlook.Application
Set objMail = objOutlook.CreateItem(olMailItem)

With objMail

    '.Display is so i can save the signature
    signature = .Getinspector
    signature = .Htmlbody
    'instead of the line above i also tried "Signature = .GetInspector"
    
    .to = Emailaddress.Value
    .Subject = "Test email to not Display"
    .Htmlbody = "Input variable information here" & "<br><br>" & signature
    .Close olsave
End With

Set objMail = Nothing
Next
End Sub

incase anyone sees this and needs an answer i have figured it out

JavaScript中的大多数陈述和声明必须用半柱终止,但是,为了方便程序员(较少的打字,风格偏好,较少的代码噪声,较低的代码噪声,较低的入口障碍),在某些源文本位置可能会省略半元素,并在某些源文本位置省略。运行时会根据规格中的一组规则设置自动插入半洛龙。

规范规则:如果将半隆作为空语言解析,或者该半隆将成为 for 语句的标题中的两个分号之一,则永远不会自动插入半分号。

规则1

如果JavaScript解析器遇到一个令牌,则将自动插入半分离,如果不存在半分离符,则不允许两者都允许两者都允许,并且该令牌与以前的终结者(例如,新行)(例如,新线)将令牌与以前的差异分开。闭合支架} ,或do-where循环的最终括号()。

换句话说:源文本位置无论如何都需要终止语句的源文本位置,如果省略了语句终结器(; ),则将自动插入。该规则是ASI的核心。

规则2

如果源文本不是有效的脚本或模块,则将在程序末尾插入半分析。换句话说:程序员可以省略程序中的最后一个半隆。

规则3,

如果遇到一个令牌,如果遇到一个令牌,则如果不存在半隆,则将自动插入,但在几个特殊的源文本位置之一(限制性限制的生产)中存在,这是明确禁止行的一个特殊源文本位置之一终结者是出于避免歧义的原因。

禁止在哪个线路终止器内部的限制作品是:

  • Postfix ++ 和Postfix - - (因此,Newline之后的Unary增量/减少操作员将绑定到<< em>以下(不是以前的)语句,作为前缀操作员)
  • 继续 break throw 返回,<代码>屈服
  • 箭头函数参数列表之后,以及
  • async 在async函数声明中的关键字&amp;表达式,发电机函数声明&amp;表达式&amp;方法和异步箭头函数

规格包含完整的详细信息以及遵循实际建议:

对Ecmasimpript程序员的最终实用建议是:

  • Postfix ++或 - 操作员应与其操作数相同的行。

  • 返回或投掷语句或一个表达式
    收益率表达式中的分配表达应在同一开始
    行为返回投掷 yarts 令牌。

  • 中断> Break 继续语句应与 break> break 继续< /代码>令牌。


  • 箭头函数参数的末端(S)及其 =&gt; 应在同一行上。

  • async 在异步函数或方法之前的令牌应与立即后面的立即行。


ASI GOTCHA示例

启动了``(``

与关闭括号配对时)。

开头括号字符具有多个含义。它可以描述一个表达式,也可以指示调用(例如, .log(...)不是一个函数“因为运行时尝试调用 console.log('bar')的返回值:

let a = 'foo'
console.log('bar')
(a = 'bam') 

一个解决方案,如果您通常省略了半隆,是包括一个分号以使您的意图明确:

let a = 'foo'
console.log('bar')
;(a = 'bam') // note semicolon at start of line

使用``

开头括号字符( [)具有多种含义。声明数组(与闭合括号配对时),或者可以指示数组破坏

。在 console.log('bar')的响应中,名为“ foo”的属性的价值:

let a = 'foo'
console.log('bar')
[a] = ['bam']

如果通常省略半隆,则是一个解决方案,是包括一个半隆来使您的意图变得明确。 :

let a = 'foo'
console.log('bar')
;[a] = ['bam'] // note semicolon at start of line

Most statements and declarations in JavaScript must be terminated with a semicolon, however, for the convenience of the programmer (less typing, stylistic preference, less code noise, lower barrier to entry), semicolons may be omitted in some source text locations, with the runtime automatically inserting semicolons according to a set of rules set-out in the spec.

Over-arching rules: a semicolon is never inserted automatically if the semicolon would then be parsed as an empty statement or if that semicolon would become one of the two semicolons in the header of a for statement.

Rule 1

A semicolon will be automatically inserted if a token is encountered by the JavaScript parser that both would not be allowed if a semicolon did not exist, and that token is separated from the previous by one or more line terminators (eg. newlines), a closing brace }, or the final parenthesis ()) of a do-while loop.

In other words: source text locations where statements would always need to be terminated anyway for a runnable program, will have the statement terminator (;) inserted automatically if it is omitted. This rule is the heart of ASI.

Rule 2

A semicolon will be inserted at the end of the program if the source text is not otherwise a valid script or module. In other words: programmers can omit the final semicolon in a program.

Rule 3

A semicolon will be automatically inserted if a token is encountered that would normally be allowed if a semicolon did not exist, but exists within one of several special source text locations (restricted productions) that explicitly disallow line terminators within them for reasons of avoiding ambiguity.

The restricted productions inside of which line terminators are prohibited are:

  • before postfix ++ and postfix -- (so the unary increment/decrement operators after a newline will bind to the following (not previous) statement, as a prefix operator)
  • after continue, break, throw, return, yield
  • after arrow function parameter lists, and
  • after the async keyword in async function declarations & expressions, generator function declarations & expressions & methods, and async arrow functions

The spec contains the full details, plus the following practical advice:

The resulting practical advice to ECMAScript programmers is:

  • A postfix ++ or -- operator should be on the same line as its operand.

  • An Expression in a return or throw statement or an
    AssignmentExpression in a yield expression should start on the same
    line as the return, throw, or yield token.

  • A LabelIdentifier in a break or continue statement should be on the same line as the break or continue token.

  • The end of an arrow function's parameter(s) and its => should be on the same line.

  • The async token preceding an asynchronous function or method should be on the same line as the immediately following token.

And this is the best article on the Web on this subject.

ASI Gotcha Examples

Starting a line with `(`

The opening parenthesis character has multiple meanings. It can delineate an expression, or it can indicate an invocation (when paired with a closing parenthesis).

For example, the following throws "Uncaught TypeError: console.log(...) is not a function" because the runtime attempts to invoke the return value of console.log('bar'):

let a = 'foo'
console.log('bar')
(a = 'bam') 

One solution for this, if you are generally omitting semicolons, is to include a semicolon to make your intentions unambiguous:

let a = 'foo'
console.log('bar')
;(a = 'bam') // note semicolon at start of line

Starting a line with `[`

The opening bracket character ([) has multiple meanings. It can indicate an object property access, or it can indicate the literal declaration of an array (when paired with a closing bracket), or it can indicate an array destructuring.

For example, the following throws "Uncaught TypeError: Cannot set properties of undefined (setting 'foo')" because the runtime attempts to set the value of a property named 'foo' on the response of console.log('bar'):

let a = 'foo'
console.log('bar')
[a] = ['bam']

One solution for this, if you are generally omitting semicolons, is to include a semicolon to make your intentions unambiguous:

let a = 'foo'
console.log('bar')
;[a] = ['bam'] // note semicolon at start of line
