从我看到的full_url只是一个串联的字符串,显然没有方法/属性searchParams像对象一样。

因此,我们知道full_url.searchparams是未定义的。
这将评估

const search_params = undefined

哪些导致您的问题。

您使用调试器了吗?看到运行时的full_url看起来会很有帮助。尽管如此,这里应该是一个问题。

From what I see full_url is just a concatenated string which obviously has no method/attribute searchParams like an object would have.

So we know that full_url.searchParams is undefined.
This would evaluate to

const search_params = undefined

which results in your problem.

Did you use a debugger? It would be helpful to see what full_url looks like during run-time. Nonetheless, it being a string should be the problem here.

委托是一个不错的选择,但是如果您想简单地保持它,则可以使用Switch语句代替IF语句,并且可以易于维护。

这是基本的,但也许会有所帮助

static void Main(string[] args)
        {
            Console.WriteLine("call skill");
            string _skill = Console.ReadLine();
            CallSkills(_skill);
        }

        public static void CallSkills(string skillname)
        {
            switch (skillname)
            {
                case "skill1":
                    //call skill1 method
                    break;
                case "skill2":
                    //call skill2 method
                    break;
                case "skill3":
                    //call skill3 method
                    break;
                case "skill4":
                    //call skill4 method
                    break;
                case "skill5":
                    //call skill5 method
                    break;
                default:
                    break;
            }
        }

Delegates are a good option but if you want to keep it simple you can use switch statement instead of if statements and it will be easy to maintain.

It's basic but maybe it will help

static void Main(string[] args)
        {
            Console.WriteLine("call skill");
            string _skill = Console.ReadLine();
            CallSkills(_skill);
        }

        public static void CallSkills(string skillname)
        {
            switch (skillname)
            {
                case "skill1":
                    //call skill1 method
                    break;
                case "skill2":
                    //call skill2 method
                    break;
                case "skill3":
                    //call skill3 method
                    break;
                case "skill4":
                    //call skill4 method
                    break;
                case "skill5":
                    //call skill5 method
                    break;
                default:
                    break;
            }
        }

那是(可能的)在纯HTML+CSS中不可行。使用JS,这非常简单:每次生成随机颜色并更改元素的样式时,请收听元素。快速而肮脏的原型:

const checkedSlider = document.querySelector(".toggle .slider");

const randomInt = max => Math.floor(Math.random() * max);

checkbox.addEventListener("click", e => {
  if (e.target.checked) {
    const r = randomInt(256);
    const g = randomInt(256);
    const b = randomInt(256);
    checkedSlider.style.backgroundColor = `rgb(${r},${g}, ${b})`
  } else {
    checkedSlider.style.backgroundColor = "lightgray";
  }
});

https://jsfiddle.net/ryxvpdog/

That's (probably) not doable in pure HTML+CSS. With JS, it's quite straightforward: listen on element being clicked, every time generate a random color and change the element's style. A quick and dirty prototype:

const checkedSlider = document.querySelector(".toggle .slider");

const randomInt = max => Math.floor(Math.random() * max);

checkbox.addEventListener("click", e => {
  if (e.target.checked) {
    const r = randomInt(256);
    const g = randomInt(256);
    const b = randomInt(256);
    checkedSlider.style.backgroundColor = `rgb(${r},${g}, ${b})`
  } else {
    checkedSlider.style.backgroundColor = "lightgray";
  }
});

然后,您可以直接使用文本查找定位器,然后单击它,类似:

cy.contains('Tool').click()

对于搜索按钮,您具有ARIA-LABEL标签,您可以直接使用它:

cy.get('input[aria-label*="main-search-box"]').type('text')

Then You can directly use the text to find the locator and click it, something like:

cy.contains('Tool').click()

For the search button, you have the aria-label tag, you can use that directly:

cy.get('input[aria-label*="main-search-box"]').type('text')

创建一个接受JSON类型对象的构造函数:

class Report {
  created_at!: Date;
  updated_at!: Date;
  
  constructor({created_at, updated_at}: {created_at: string, updated_at: string}) {
      this.created_at = new Date(created_at);
      this.updated_at = new Date(updated_at);
  }
}

let jsonBody = [{"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}, {"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}];

let arr: Report[] = jsonBody.map(obj => new Report(obj));

Create a constructor that accepts an object of the json type:

class Report {
  created_at!: Date;
  updated_at!: Date;
  
  constructor({created_at, updated_at}: {created_at: string, updated_at: string}) {
      this.created_at = new Date(created_at);
      this.updated_at = new Date(updated_at);
  }
}

let jsonBody = [{"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}, {"created_at":"2016-02-04","updated_at":"2016-02-04 00:45:56.000"}];

let arr: Report[] = jsonBody.map(obj => new Report(obj));

set_site_transient( 'my_transient_data', $my_data, 100000 );
// 100000 is the expiration date(in seconds)..


// Get array....
get_site_transient('my_transient_data' );

// Delete the Transient...

首先,您需要将以下代码行传递到on ConconFiguring方法:

base.OnConfiguring(optionsBuilder);

dbContextoptions实例的情况下,可能或可能不会将其传递给构造函数,您可以使用dbContextOptionsBuilder.isconfigured来确定是否已经设置了选项,并在on Configuring(dbcontextoptionsbuilder)中跳过某些或全部逻辑。

First of all, you need to pass the following line of code into your OnConfiguring method:

base.OnConfiguring(optionsBuilder);

In situations where an instance of DbContextOptions may or may not have been passed to the constructor, you can use DbContextOptionsBuilder.IsConfigured to determine if the options have already been set, and skip some or all of the logic in OnConfiguring(DbContextOptionsBuilder) .

  • 在python中,encodedString [:2]/encodedstring [i:i+2]encodedString中提取两个字符。飞镖等效(假设ASCII字符)将是encodedString.substring(0,2)encodedString(i,i,i + 2)

  • 等效于Python的''。join(list) in Dart是list.join()。。

  • python列表综合的等效物([i in quote in quote])中的dart是collection- for :[for(for for(项目中的var I) )i]

  • 在范围内(2,len(encodedString),2)在dart中,

    python的等效是使用基本for loop, loop with start,witch,corditi和增量:for(var i = 2; i< encodedString.length; i += 2)

  • 在python中,int(String,16) parses 字符串作为十六进制数字。在DART中,使用int.parse(字符串,radix:16)

  • 在python中,chr(integer)从指定的代码点创建一个字符串。飞镖中的等效物为string.fromcharcode(integer)

将所有这些放在一起:

String cfDecodeEmail(String encodedString) {
  var r = int.parse(encodedString.substring(0, 2), radix: 16);
  var email = [
    for (var i = 2; i < encodedString.length; i += 2)
      String.fromCharCode(
        int.parse(encodedString.substring(i, i + 2), radix: 16) ^ r,
      )
  ].join();
  return email;
}

void main() {
  // Prints: [email protected]
  print(cfDecodeEmail('543931142127353935313e352e7a373b39'));
}
  • In Python, encodedString[:2]/encodedString[i:i+2] extract two characters from encodedString. The Dart equivalent (assuming ASCII characters) would be encodedString.substring(0, 2) and encodedString(i, i + 2) respectively.

  • The equivalent of Python's ''.join(list) in Dart is list.join().

  • The equivalent of a Python's list comprehensions ([i for i in items]) in Dart is collection-for: [for (var i in items) i].

  • The equivalent of Python's for i in range(2, len(encodedString), 2) in Dart is to use a basic for loop with a start, condition, and increment: for (var i = 2; i < encodedString.length; i += 2).

  • In Python, int(string, 16) parses string as a hexadecimal number. In Dart, use int.parse(string, radix: 16).

  • In Python, chr(integer) creates a string from the specified code point. The equivalent in Dart is String.fromCharCode(integer).

Putting it all together:

String cfDecodeEmail(String encodedString) {
  var r = int.parse(encodedString.substring(0, 2), radix: 16);
  var email = [
    for (var i = 2; i < encodedString.length; i += 2)
      String.fromCharCode(
        int.parse(encodedString.substring(i, i + 2), radix: 16) ^ r,
      )
  ].join();
  return email;
}

void main() {
  // Prints: [email protected]
  print(cfDecodeEmail('543931142127353935313e352e7a373b39'));
}

这就是我设法与颤动所做的。建议您为您工作

您首先需要添加梯度

final Gradient  _gradient = const LinearGradient(
        begin:  Alignment(0.5, 1),
        end: Alignment(0.5, 0),
        colors: <Color>[
          Color(0xff1f005c),
          Color(0xffffb56b),
          
        ],
        stops : [1,1],
        tileMode: TileMode.clamp,
      );

,然后将文本更改为:

ShaderMask(
      blendMode: BlendMode.modulate,
      shaderCallback: (size) => _gradient.createShader(
        Rect.fromLTWH(0, 0, size.width, size.height),
      ),
      child: Text(
        'ABCDEFGH',
        style: TextStyle(
          color: Colors.white,
          fontWeight: FontWeight.bold,
          fontSize: 60,
        ),),
      )

This is what I have managed to do with flutter . Propably works for you
ReCreation in flutter

You first need to add the Gradient

final Gradient  _gradient = const LinearGradient(
        begin:  Alignment(0.5, 1),
        end: Alignment(0.5, 0),
        colors: <Color>[
          Color(0xff1f005c),
          Color(0xffffb56b),
          
        ],
        stops : [1,1],
        tileMode: TileMode.clamp,
      );

Then you change your text to this :

ShaderMask(
      blendMode: BlendMode.modulate,
      shaderCallback: (size) => _gradient.createShader(
        Rect.fromLTWH(0, 0, size.width, size.height),
      ),
      child: Text(
        'ABCDEFGH',
        style: TextStyle(
          color: Colors.white,
          fontWeight: FontWeight.bold,
          fontSize: 60,
        ),),
      )

您可以使用点(“。”)从嵌套数组中加速项目,然后使用.push操作员将项目添加到数组中。

var tratamentos = {
      "Sr": ["Casado", "Solteiro"],
      "Sra": ["Casada", "Solteira"],}
tratamentos.Sr.push("Desquitado", "Enrolado");
console.log(tratamentos);

You can acces items from the nested array using dots (".") and then use .push operator to add items to the array.

var tratamentos = {
      "Sr": ["Casado", "Solteiro"],
      "Sra": ["Casada", "Solteira"],}
tratamentos.Sr.push("Desquitado", "Enrolado");
console.log(tratamentos);
