TypeScript仅定义基本类型,例如布尔,字符串,数字,枚举等。它是JavaScript的超级集合,因此您可以在JavaScript中通常会在同一文档对象模型上进行编码。所有JavaScript也是有效的打字稿。

如果您没有完成代码,那么它是环境的,而不是打字稿语言的问题。

Typescript only defines basic types like boolean, string, number, enum, etc. It is a super-set of javascript so you can code against the same Document Object Model you normally would in javascript. All javascript is also valid Typescript.

If you are not getting code completion then it is environmental, not an issue with the Typescript language.

2017答案:您现在可以在当前的每个浏览器中完全做您想要的操作, noreferrer”> node.js

这很简单:

async代码的版本:

(async function(){

    var response = await superagent.get('...')
    console.log(response)

})()

在所有当前浏览器和node.js 8 中都支持等待

2017 answer: you can now do exactly what you want in every current browser and Node.js

This is quite simple:

  • Return a Promise
  • Use the 'await', which will tell JavaScript to await the promise to be resolved into a value (like the HTTP response)
  • Add the 'async' keyword to the parent function

Here's a working version of your code:

(async function(){

    var response = await superagent.get('...')
    console.log(response)

})()

await is supported in all current browsers and Node.js 8

预计约束将是字典列表,因此使用

cons2 = [{'type': 'eq',   'fun': eqcon},
         {'type': 'ineq', 'fun': ineq1}]

应解决您的问题。话虽如此,字典中的键应该是独一无二的。否则,您将无法通过模棱两可的键在字典中访问特定值。

The constraints are expected to be a list of dictionaries, so using

cons2 = [{'type': 'eq',   'fun': eqcon},
         {'type': 'ineq', 'fun': ineq1}]

should fix your problem. That being said, the keys inside a dictionary should be unique. Otherwise, you aren't able to access a specific value in the dictionary by ambiguous keys.

简单的不平等约束破坏QP问题(控制分配)

首先,如果您在5.3之前处于PHP,则不。您有很多问题要解决。

我很惊讶没有人提到 intl 库,一个具有良好支持的库对于 unicode graphemes 字符串操作本地化等等,请参见下文。

我将引用伊丽莎白·史密斯(Elizabeth Smith)的 幻灯片 phpbenelux'14

intl

好:

  • ICU图书馆
  • 标准化环境周围的包装器,每个脚本
  • 格式化
  • 货币格式格式
  • 格式格式格式(替换getText)
  • 日历,日期,时间区域和时间
  • 倾斜器
  • spooofchecker
  • 资源捆绑
  • 转换器
  • IDN支持
  • graphemes
  • collat
  • ​​ionanter

不好:

  • 不支持zend_multibyte不支持zend_multibyte
  • 不支持zend_multibyte, http输入输出转换
  • 不​​支持函数过载

mb_string

  • 启用zend_multibyte支持
  • 支持透明的http in/out编码
  • 为功能提供了一些包装器,例如strtoupper

iconv

  • charset转换
  • 输出输出输出buffer handler
  • Mime编码功能
  • 转换
  • 一些弦乐器(LEN,substr,strpos,strrpos)
  • ,过滤 stream_filter_append($ fp, 'convert.iconv.iso-2022-jp/euc-jp')

数据库

  • mysql:表和连接上的charset和collat​​ion和Collat​​ion(不是整理)。另外,请勿使用mysql -mysqli或pdo
  • postgresql:pg_set_client_encoding
  • sqlite(3):请确保它是用Unicode和intl Support编译的,intl and intl Support

其他一些gotchas

  • 您不能使用php和windows的unicode文件,除非您使用PHP和Windows,否则使用第三部分扩展。
  • 使用exec,请发送ASCII中的所有
  • 如果您
  • 内容

First of all, if you are in PHP before 5.3 then no. You've got a ton of problems to tackle.

I am surprised that none has mentioned the intl library, the one that has good support for Unicode, graphemes, string operations, localisation and many more, see below.

I will quote some information about Unicode support in PHP by Elizabeth Smith's slides at PHPBenelux'14

INTL

Good:

  • Wrapper around ICU library
  • Standardised locales, set locale per script
  • Number formatting
  • Currency formatting
  • Message formatting (replaces gettext)
  • Calendars, dates, time zone and time
  • Transliterator
  • Spoofchecker
  • Resource bundles
  • Convertors
  • IDN support
  • Graphemes
  • Collation
  • Iterators

Bad:

  • Does not support zend_multibyte
  • Does not support HTTP input output conversion
  • Does not support function overloading

mb_string

  • Enables zend_multibyte support
  • Supports transparent HTTP in/out encoding
  • Provides some wrappers for functionality such as strtoupper

ICONV

  • Primary for charset conversion
  • Output buffer handler
  • mime encoding functionality
  • conversion
  • some string helpers (len, substr, strpos, strrpos)
  • Stream Filter stream_filter_append($fp, 'convert.iconv.ISO-2022-JP/EUC-JP')

DATABASES

  • MySQL: Charset and collation on tables and on the connection (not the collation). Also, don't use mysql - mysqli or PDO
  • postgresql: pg_set_client_encoding
  • sqlite(3): Make sure it was compiled with Unicode and intl support

Some other gotchas

  • You cannot use Unicode filenames with PHP and windows unless you use a 3rd part extension.
  • Send everything in ASCII if you are using exec, proc_open and other command line calls
  • Plain text is not plain text, files have encodings
  • You can convert files on the fly with the iconv filter

UTF-8一直通过

我会尝试使用Axios而不是获取,但在我看来,它更有用,除此之外,尝试在Blob的定义上设置错误边界,我真的相信这个问题在那里存在。

祝你好运!

I would try to use Axios instead of Fetch, Its more useful in my opinion, Other than that, try setting up an error boundary around the definition of blob, I truly believes the problem lays there.

Good luck!

您需要查看背景工作者示例:

您无法使用django模板标签“ {%%}” in .js:

 single_email_div.innerHTML = `<a href="{%url 'email' email.id %}">

在这里您已经应该有

single_email_div.innerHTML = `<a href="/emails/${email.id}/">

you are can not use django template tags "{% %}" in .js:

 single_email_div.innerHTML = `<a href="{%url 'email' email.id %}">

Here you already should have

single_email_div.innerHTML = `<a href="/emails/${email.id}/">

在跳入大火之前,回顾一下bash脚本的基础是有帮助的。

if [ "foo" = "foo" ]
then
    echo "Equal"
else
    echo "Not Equal"
fi

在bash脚本中,变量和括号之间的间距很重要,这意味着上述语句与 [“ foo” ==“ foo”] (请注意,缺少空间)

现在让我们开始 如果您要比较整数,则添加一个循环

for i in {1..10}
do
    if [ $i -eq 1 ]
    then
        echo "Equal"
    else
        echo "Not Equal"
    fi
done

,应使用 -eq 进行等效比较。

确保您添加“做”和“完成”语句。它有助于使用代码中的凹痕,以便更轻松地遵循脚本执行。所有4个空间都将在循环内执行。

从这里,您应该能够构建到最终脚本,该脚本检查用户输入。

跳入并尝试新事物很有趣,但是请务必参考文档!

It's helpful to review the basics of Bash Scripting a bit more before jumping into the fire.

if [ "foo" = "foo" ]
then
    echo "Equal"
else
    echo "Not Equal"
fi

In Bash script, the spacing between variables and brackets is significant, meaning the if statement above is NOT the same as [ "foo"=="foo"] (Notice the lack of a space)

Now let's add a loop

for i in {1..10}
do
    if [ $i -eq 1 ]
    then
        echo "Equal"
    else
        echo "Not Equal"
    fi
done

If you're comparing integers, you should use -eq for an equals comparison.

Make sure you're adding the 'do' and 'done' statements. It helps to use indents in your code to make it easier to follow the script execution. Everything 4 spaces over will execute inside the loop.

From here you should be able to build up to your final script which checks for user input.

It's fun to jump in and try new things but always be sure to reference the documentation! https://www.gnu.org/savannah-checkouts/gnu/bash/manual/bash.html#Shell-Commands

这里有几个活动部件。首先,您说的是“运动学模拟”,但是“让我们让您的机器人”中的演示不会模拟(物理学),它只会可视化滑块设置的运动学。假设这足以满足您的目标,则可以将回调传回您的 sliders.run method(就像我在笔记本中所做的那样,对应于本章),我相信,如果您在该回调中调用 plant.setpositions ,它应该有效吗?

There are a few moving parts here. First, you say "kinematic simulation", but the demonstration in "Let's get you a robot" does not simulate (physics), it only visualizes the kinematics as set by the sliders. Assuming that is sufficient for your goal, then you could pass a callback into your sliders.Run method (as I do in the notebook corresponding to this chapter), and I believe that if you call plant.SetPositions in that callback, it should work?

您可以尝试以下操作吗?并且请尝试合并单个服务帐户中的所有秘密。

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: run-pipeline
  namespace: tekton-pipelines
spec:
  serviceAccountName: git-service-account
  pipelineRef:
    name: fetebird-discount
  workspaces:
    - name: shared-workspace
      persistentVolumeClaim:
        claimName: fetebird-discount-pvc
  params:
    - name: repo-url
      value: [email protected]:anandjaisy/discount.git

我可以在这里尝试互相建议。您是否包括此处建议的注释?

apiVersion: v1
kind: Secret
metadata:
  name: ssh-key
  annotations:
    tekton.dev/git-0: github.com # Described below
type: kubernetes.io/ssh-auth
stringData:
  ssh-privatekey: <private-key>
  # This is non-standard, but its use is encouraged to make this more secure.
  # If it is not provided then the git server's public key will be requested
  # when the repo is first fetched.
  known_hosts: <known-hosts>

Can you try the following? And please try to merge all the secrets in the single service account.

apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
  name: run-pipeline
  namespace: tekton-pipelines

        claimName: fetebird-discount-pvc
  params:
    - name: repo-url
      value: [email protected]:anandjaisy/discount.git

There is one another suggestion i could try here. Did you include the annotation like suggested here?

问题是:

如何从异步呼叫中返回响应?

哪个可以解释为:

如何制作异步代码外观同步

解决方案将是避免回调,并结合 Promises async/等待

我想为Ajax请求举一个示例。

(尽管可以用JavaScript编写,但我更喜欢用python编写它,然后使用 transcrypt

>

__pragma__ ('alias', 'S', '

a >在这种情况下,一个ajax调用:

def read(url: str):
    deferred = S.Deferred()
    S.ajax({'type': "POST", 'url': url, 'data': { },
        'success': lambda d: deferred.resolve(d),
        'error': lambda e: deferred.reject(e)
    })
    return deferred.promise()

使用异步代码,就好像它是同步

async def readALot():
    try:
        result1 = await read("url_1")
        result2 = await read("url_2")
    except Exception:
        console.warn("Reading a lot failed")
)

a >在这种情况下,一个ajax调用:


使用异步代码,就好像它是同步


The question was:

How do I return the response from an asynchronous call?

which can be interpreted as:

How to make asynchronous code look synchronous?

The solution will be to avoid callbacks, and use a combination of Promises and async/await.

I would like to give an example for an Ajax request.

(Although it can be written in JavaScript, I prefer to write it in Python, and compile it to JavaScript using Transcrypt. It will be clear enough.)

Let’s first enable jQuery usage, to have $ available as S:

__pragma__ ('alias', 'S', '

Define a function which returns a Promise, in this case an Ajax call:

def read(url: str):
    deferred = S.Deferred()
    S.ajax({'type': "POST", 'url': url, 'data': { },
        'success': lambda d: deferred.resolve(d),
        'error': lambda e: deferred.reject(e)
    })
    return deferred.promise()

Use the asynchronous code as if it were synchronous:

async def readALot():
    try:
        result1 = await read("url_1")
        result2 = await read("url_2")
    except Exception:
        console.warn("Reading a lot failed")
)

Define a function which returns a Promise, in this case an Ajax call:


Use the asynchronous code as if it were synchronous:

Usenavigator是一个钩子,您无法直接在类组件中使用任何钩子。为了完成它,您需要在高阶组件中调用Usenavigator Hook,然后将类组件包裹起来。

您可以查看,我如何使用React React React React Classic class 组件中的钩子?

useNavigator is a hook, and you can not use any hook directly in a class component. In order to get it done you need to call useNavigator hook in a higher-order component and wrap the class component by it.
