您是否在另一个设备上使用相同的键盘(正在使用的设备)?
我可以根据我的期望说,某些键盘不响应DE输入类型,它们只是显示默认或数字键盘。

例如,在使用SwiftKey的设备上,当将键盘设置为仅数字时,它不会更改任何内容,只需显示de默认键盘即可。

Are you using the same keyboard on the other device (the one which is working)?
I can say based on my expirience that some keyboards do not responde to de input type and they just show a default or numeric keyboard.

For example on devices using SwiftKey, when keyboard is set to only numeric it doesn't change anything, just shows de default keyboard.

textInputType.dateTime未显示'/' & ':'符号

这样做的不是tabview本身,例如

    TabView {
        ForEach(viewModel.images) { image in
            WebImage(url: image)
                .fitToAspectRatio(.sixteenToNine)
        }
        .aspectRatio(1.77, contentMode: .fit)      // << here !!
        .cornerRadius(4)
    }
    .tabViewStyle(PageTabViewStyle())

Do it for content not for TabView itself, like

    TabView {
        ForEach(viewModel.images) { image in
            WebImage(url: image)
                .fitToAspectRatio(.sixteenToNine)
        }
        .aspectRatio(1.77, contentMode: .fit)      // << here !!
        .cornerRadius(4)
    }
    .tabViewStyle(PageTabViewStyle())

您可以通过将代码放入通用类中来缓存静态字段中的Getter委托。

然后,您可以使用更多仿制药使用两级类层次结构来缓存属性本身。

public List<string> Compare<T>(T A, T B)
{
    return GenericComparer<T>.Compare(A, B);
}

abstract class PropertyCompareBase<T>
{
    public string Name;
    public abstract bool CompareProperty(T A, T B);
}

class PropertyCompare<T, TProperty> : PropertyCompareBase<T>
{
    Func<T, TProperty> Getter;

    public PropertyCompare(PropertyInfo prop)
    {
        Name = prop.Name;
        Getter = (Func<T, TProperty>)prop.GetMethod.CreateDelegate(typeof(Func<T, TProperty>));
    }

    public override bool CompareProperty(T A, T B)
    {
        return EqualityComparer<TProperty>.Default.Equals(Getter(A), Getter(B));
    }
}

static class GenericComparer<T>
{
    static List<PropertyCompareBase<T>> properties = typeof(T)
        .GetProperties(BindingFlags.Public | BindingFlags.Instance)
        .Where(p => p.GetIndexParameters().Length == 0)
        .Select(p => (PropertyCompareBase<T>)Activator.CreateInstance(
                         typeof(PropertyCompare<,>)
                         .MakeGenericType(typeof(T), p.PropertyType),
                        p))
        .ToList();

    static public List<string> Compare(T A, T B)
    {
        List<string> unequalProperties =
            properties.Where(p => !p.CompareProperty(A, B))
                      .Select(p => p.Name)
                      .ToList();
        return unequalProperties;
    }
}

You can cache the getter delegates in a static field, by putting your code into a generic class.

You can then cache the properties themselves using a two-level class hierarchy using some more generics.

public List<string> Compare<T>(T A, T B)
{
    return GenericComparer<T>.Compare(A, B);
}

abstract class PropertyCompareBase<T>
{
    public string Name;
    public abstract bool CompareProperty(T A, T B);
}

class PropertyCompare<T, TProperty> : PropertyCompareBase<T>
{
    Func<T, TProperty> Getter;

    public PropertyCompare(PropertyInfo prop)
    {
        Name = prop.Name;
        Getter = (Func<T, TProperty>)prop.GetMethod.CreateDelegate(typeof(Func<T, TProperty>));
    }

    public override bool CompareProperty(T A, T B)
    {
        return EqualityComparer<TProperty>.Default.Equals(Getter(A), Getter(B));
    }
}

static class GenericComparer<T>
{
    static List<PropertyCompareBase<T>> properties = typeof(T)
        .GetProperties(BindingFlags.Public | BindingFlags.Instance)
        .Where(p => p.GetIndexParameters().Length == 0)
        .Select(p => (PropertyCompareBase<T>)Activator.CreateInstance(
                         typeof(PropertyCompare<,>)
                         .MakeGenericType(typeof(T), p.PropertyType),
                        p))
        .ToList();

    static public List<string> Compare(T A, T B)
    {
        List<string> unequalProperties =
            properties.Where(p => !p.CompareProperty(A, B))
                      .Select(p => p.Name)
                      .ToList();
        return unequalProperties;

对于列表,您只能一次附加一项。如果您想保留Capital_quantity,并且我在一起可以将它们附加到您的列表中,即

caps.append([capital_quantity,i])

值得注意的话,如果出于任何原因,您想在平坦的结构中添加两个值,而不是嵌套列表使用.extend()方法。 this 是理解行为的好教程。

For lists, you can only append one item at a time. If you would like to keep capital_quantity and i together you could append them to your list as a secondary list i.e.

caps.append([capital_quantity,i])

Its worth noting, if for whatever reason you want to add both values to your list in a flat structure rather than a nested list you could use the.extend() method. This is a good tutorial to understand the behavior.

typeerror:list.append()通过迭代附加阵列时,请完全引起一个参数(2给定)错误

为什么有些浏览器会有它,而有些则没有

Edge和以前的Internet Explorer版本也具有相同Webkit引擎称为闪烁引擎,这就是为什么您会看到Chrome之间的区别。由于在iOS设备上,Edge使用WebKit引擎,因此检查其在移动设备上的行为可能也很不错。

W3C设置了HTML元素的标准,包括输入类型=“密码”,该标准由负责制定Web标准以确保Web2的长期增长。

为什么有时会出现

这是边缘“眼”图标的正常行为,如果您没有在密码字段中输入任何输入,它将显示眼睛图标,直到您模糊输入,如果您再次将输入集中在文本中,它将不再显示眼睛图标了,我的猜测是因为安全问题(例如,让计算机闲置的人和攻击者稍后再回来)。如果要再次触发眼图,则需要从输入中删除所有字符,然后再次键入。

尝试一下

对此进行测试。

<input type="password">

您会看到眼睛显示密码切换图标并未显示为Firefox和其他浏览器,但对于Edge而言。

创建自定义眼功能

用于删除它您可以使用CSS,然后搜索使用其自身功能将自己的图标添加到输入中的方法,例如,您只需在输入旁边添加一个按钮然后使用CSS对其进行样式,以提供输入的切换功能,例如,您可以将类型的属性更改为文本,然后返回密码,例如:

function peakPassword() {
  var passwordField = document.getElementById('password');
  if (passwordField.getAttribute('type') === 'password') {
    passwordField.setAttribute('type', 'text');
  } else {
    passwordField.setAttribute('type', 'password');
  }
}
<input type="password" id="password">
<button id="button" onClick="peakPassword()">Peak</button>

然后,您当然需要更改按钮的样式并将其放置在输入字段中,或者只需从输入密码字段中删除眼睛图标:

input::-ms-reveal {
  display: none;
}
<input type="password" value="">

Why some browsers have it and some don't

This is the case for Edge and previous versions of Internet Explorer also had the same, it has a built-in password reveal button set by default by their own forked webkit engine which is called blink engine, that's why you see the difference between chrome for example. Might also be good to check how it behaves on mobile devices because on iOS devices, Edge uses webkit engine.

This standards for HTML elements, including input type="password", are set by the W3C which is responsible for developing web standards to ensure the long-term growth of the web2.

Why it appears sometimes

That's the normal behaviour of Edge "eye" icon, if you haven't put any input into the password field it will show the eye icon until you blur out of the input, if you focus the input again and it had text, it will not show the eye icon anymore, my guess is because of security issues (e.g. someone that left the computer idle and an attacker comes back later). If you want to trigger the eye icon again you would need to remove all the characters from the input and type again.

Try it out

To test this you can just open a jsFiddle with only a input type="password" and check it on different browsers:

<input type="password">

You'll see that the eye reveal password toggle icon doesn't appear for firefox and other browsers but it does for Edge.

Creating Custom Eye functionality

For removing it you can use CSS, and then search for a way of adding your own icon to the input with it's own functionality, for example you could just add a button next to the input and then style it with CSS to provide the toggle functionality of the input, and you could just for example change the attribute of the type to a text, and back to a password, like so:

function peakPassword() {
  var passwordField = document.getElementById('password');
  if (passwordField.getAttribute('type') === 'password') {
    passwordField.setAttribute('type', 'text');
  } else {
    passwordField.setAttribute('type', 'password');
  }
}
<input type="password" id="password">
<button id="button" onClick="peakPassword()">Peak</button>

Then of course you would need to change the style of the button and make it inside the input field, or just remove the eye icon from the input password field like this:

input::-ms-reveal {
  display: none;
}
<input type="password" value="">

密码字段上的眼睛图标有时是可见的,有时看不到

简短而简单:,因为您要寻找的元素在文档中尚不存在(尚未)。


在此答案的其余部分中,我将使用 getElementById示例,但同样适用于 getElementsbybytbytybytybytagname querySelector ,以及任何其他dom方法选择元素。

可能的原因

有三个原因可能不存在元素:

  1. 带有传递ID的元素确实没有文档中存在。您应该仔细检查您传递给getElementById的ID是否确实与(生成的)HTML中的现有元素的ID匹配,并且您尚未 nibsellypelled ID(ID是ID(ID是) 案例敏感!)。

    如果您正在使用getElementById,请确保您唯一给出元素的ID(例如,document.getElemnTbyId(“ the-id the-id the-id) ”))。如果您使用的是接受CSS选择器的方法(例如QuerySelector),请确保您在ID之前包括 id(例如,document.queryselector(“#the-id”))。您必须使用getElementById,并且必须必须与queryselector一起使用它。和类似。另请注意,如果ID中的字符中的字符在 CSS标识符(例如; id包含的属性字符是糟糕的实践,但有效),您必须在使用QuerySelectordocument.queryselector(“#the \\。id”)<时,您必须逃脱。 /code>)),但不使用getElementByIddocument.getElementById(“ the.id”))。


  2. 目前不存在该元素您调用getElementById

  3. 即使您可以在页面上看到它,即使您可以在文档中看到它,因此该元素不在查询中,因为它在iframe中(这是其自己的文档)。 IFRAMES中的元素在搜索包含它们的文档时未搜索。

如果问题是原因3( iframe 或类似),则需要查看iframe而不是父级文档中的文档,也许是通过获取<代码> iframe 元素并使用其

第二个原因&nbsp; - 尚不存在 &nbsp; - 很普遍。浏览器分析并处理HTML从上到下。这意味着任何呼叫对DOM元素出现在HTML中之前发生的DOM元素的呼叫都会失败。

考虑以下示例:

<script>
    var element = document.getElementById('my_element');
</script>

<div id="my_element"></div>

div出现 script。目前执行脚本,元素尚不存在 getElementById将返回null

jQuery

使用jQuery的所有选择器也是如此。如果您拼写错误您的选择器,或者您正在尝试选择它们,则不会找到元素。

一个额外的转折是找不到jQuery,因为您已经没有协议加载了脚本并从文件系统运行:

<script src="//somecdn.somewhere.com/jquery.min.js"></script>

该语法用于允许脚本通过协议https://在页面上通过https加载https https://并加载http带有协议的页面上的版本http://

它具有不幸的副作用,即尝试和不加载file> file> file://somecdn.somewhere.com ...


解决方案

在调用getElementById(或任何DOM方法)之前,请确保要访问的元素存在,即加载DOM。

可以通过简单地将您的JavaScript 放在之后来确保这一点,

<div id="my_element"></div>

<script>
    var element = document.getElementById('my_element');
</script>

在这种情况下,您还可以将代码放在关闭的主体标签之前(&lt;/body&gt;) (所有DOM元素将在执行脚本时可用)。

其他解决方案包括收听“ noreferrer”> load> load [MDN] domcontentloaded [mdn] [mdn]] 事件。在这些情况下,在文档中放置JavaScript代码并不重要,您只需要记住将所有DOM处理代码放在事件处理程序中即可。

示例:

window.onload = function() {
    // process DOM elements here
};

// or

// does not work IE 8 and below
document.addEventListener('DOMContentLoaded', function() {
    // process DOM elements here
});

请参阅 are quirksmode.org 有关事件处理和浏览器差异的更多信息。

jQuery

首先确保正确加载jQuery。 使用浏览器的开发人员工具找出是否找到并纠正jQuery文件并纠正URL如果不是的话(例如,添加http:https: scheme在开始时,调整路径等。)

聆听load/domcontentloaded事件正是jQuery用 .ready() [docs] 。影响DOM元素的所有jQuery代码都应在该事件处理程序内部。

实际上, jquery tutorial 明确指出:

使用jQuery读取或操纵文档对象模型(DOM)时,我们几乎要做的事情,我们需要确保我们在DOM准备就绪后立即开始添加事件等。

为此,我们为文档注册了一个就绪事件。

  $(document).ready(function(){
 
   // do stuff when DOM is ready
});

另外,您也可以使用速记语法:

$(function() {
    // do stuff when DOM is ready
});

两者都是等效的。

Short and simple: Because the elements you are looking for do not exist in the document (yet).


For the remainder of this answer I will use getElementById for examples, but the same applies to getElementsByTagName, querySelector, and any other DOM method that selects elements.

Possible Reasons

There are three reasons why an element might not exist:

  1. An element with the passed ID really does not exist in the document. You should double check that the ID you pass to getElementById really matches an ID of an existing element in the (generated) HTML and that you have not misspelled the ID (IDs are case-sensitive!).

    If you're using getElementById, be sure you're only giving the ID of the element (e.g., document.getElemntById("the-id")). If you're using a method that accepts a CSS selector (like querySelector), be sure you're including the # before the ID to indicate you're looking for an ID (e.g., document.querySelector("#the-id")). You must not use the # with getElementById, and must use it with querySelector and similar. Also note that if the ID has characters in it that aren't valid in CSS identifiers (such as a .; id attributes containing . characters are poor practice, but valid), you have to escape those when using querySelector (document.querySelector("#the\\.id"))) but not when using getElementById (document.getElementById("the.id")).

  2. The element does not exist at the moment you call getElementById.

  3. The element isn't in the document you're querying even though you can see it on the page, because it's in an iframe (which is its own document). Elements in iframes aren't searched when you search the document that contains them.

If the problem is reason 3 (it's in an iframe or similar), you need to look through the document in the iframe, not the parent document, perhaps by getting the iframe element and using its contentDocument property to access its document (same-origin only). The rest of this answer addresses the first two reasons.

The second reason — it's not there yet — is quite common. Browsers parse and process the HTML from top to bottom. That means that any call to a DOM element which occurs before that DOM element appears in the HTML, will fail.

Consider the following example:

<script>
    var element = document.getElementById('my_element');
</script>

<div id="my_element"></div>

The div appears after the script. At the moment the script is executed, the element does not exist yet and getElementById will return null.

jQuery

The same applies to all selectors with jQuery. jQuery won't find elements if you misspelled your selector or you are trying to select them before they actually exist.

An added twist is when jQuery is not found because you have loaded the script without protocol and are running from file system:

<script src="//somecdn.somewhere.com/jquery.min.js"></script>

this syntax is used to allow the script to load via HTTPS on a page with protocol https:// and to load the HTTP version on a page with protocol http://

It has the unfortunate side effect of attempting and failing to load file://somecdn.somewhere.com...


Solutions

Before you make a call to getElementById (or any DOM method for that matter), make sure the elements you want to access exist, i.e. the DOM is loaded.

This can be ensured by simply putting your JavaScript after the corresponding DOM element

<div id="my_element"></div>

<script>
    var element = document.getElementById('my_element');
</script>

in which case you can also put the code just before the closing body tag (</body>) (all DOM elements will be available at the time the script is executed).

Other solutions include listening to the load [MDN] or DOMContentLoaded [MDN] events. In these cases it does not matter where in the document you place the JavaScript code, you just have to remember to put all DOM processing code in the event handlers.

Example:

window.onload = function() {
    // process DOM elements here
};

// or

// does not work IE 8 and below
document.addEventListener('DOMContentLoaded', function() {
    // process DOM elements here
});

Please see the articles at quirksmode.org for more information regarding event handling and browser differences.

jQuery

First make sure that jQuery is loaded properly. Use the browser's developer tools to find out whether the jQuery file was found and correct the URL if it wasn't (e.g. add the http: or https: scheme at the beginning, adjust the path, etc.)

Listening to the load/DOMContentLoaded events is exactly what jQuery is doing with .ready() [docs]. All your jQuery code that affects DOM element should be inside that event handler.

In fact, the jQuery tutorial explicitly states:

As almost everything we do when using jQuery reads or manipulates the document object model (DOM), we need to make sure that we start adding events etc. as soon as the DOM is ready.

To do this, we register a ready event for the document.

$(document).ready(function() {
   // do stuff when DOM is ready
});

Alternatively you can also use the shorthand syntax:

$(function() {
    // do stuff when DOM is ready
});

Both are equivalent.

为什么jQuery或诸如getElementById之类的DOM方法找不到元素?

尝试lm(y〜。,data)其中表示“ data除了y y

m <- matrix(rnorm(100), ncol =5)
m <- as.data.frame(m)
names(m) <- paste("m", 1:5, sep="")
lm(m1 ~., data=m)

。可以重新分配m仅包括您作为预测变量的列

m <- m[ ,2:4]
lm(m1 ~ ., data=m)

Try lm(y ~ ., data) where . means "every other column in data besides y.

m <- matrix(rnorm(100), ncol =5)
m <- as.data.frame(m)
names(m) <- paste("m", 1:5, sep="")
lm(m1 ~., data=m)

You can reassign m to include only the columns you as the predictors

m <- m[ ,2:4]
lm(m1 ~ ., data=m)

最高最高的问题实际上很常见,这是解决方案:
而不是
AmericAshigh:= ta。最高(高,AmericaSlookback)

应该这样:
AmericAshigh:= ta.hightest(高,Math.max(nz(AmericAslookback),1)))

脚本中的所有高点和低点。您只需在nz(查找期)和“ 1”之间添加Math.max。因此,如果出于何种原因脚本将回顾读为零,则将选择“ 1”。

the problem with ta.highest is actually common and here is the solution for it :
instead of
Americashigh := ta.highest(high,AmericasLookback)

it should be like this :
Americashigh := ta.highest(high,math.max(nz(AmericasLookback),1))

same thing with all highs and lows in your script. you just add math.max between the nz(Lookback period) and "1". so if the script for whatever reason reads the Lookback as zero, it will pick "1".

如果您确实需要class1的实例,而不仅仅是类名称,那么唯一的方法就是这样:

in class1

public doStuff() {
    this.field = new Class2(this);
}

in class2 in代码>:

public Class2(Class1 instance) {
    // do whatever you need with the Class1 instance)
}

If you really need the instance of Class1, and not just the class name, then the only way would be something like this:

In Class1:

public doStuff() {
    this.field = new Class2(this);
}

In Class2:

public Class2(Class1 instance) {
    // do whatever you need with the Class1 instance)
}

If your fetch action depends on a click, do not use useEffect as useEffect is intended to be used to synchronize state.


const URLS = {
  feed: '/feed',
  feedol: '/feed_ol',
  jsonData: '/json_data',
  azureData: '/azure_data'
}

    feed: [],
    feedol: [],
    jsonData: [],
    azureData: []

  })

  //reusable function
  const handleFetch = (type) => {
     fetch(URLS[type]).then((response) =>
       response.json().then((data) => {
         setData(d => ({
           ...d, [type]: data
        }));

您应该在此处关注:

注意:域需要同时添加: https://www.exam.com and Exes.com

要解决错误,请转到Firebase Console。

  1. Go Firebase Console。

  2. 单击身份验证。

  3. 单击登录方法。

  4. 向下滚动并检查授权域。

  5. 添加您实现电话身份验证的网站地址。

You should follow in here:

Note: The domain need to add both: https://www.exam.com and exam.com

To resolve the error, go to firebase console.

  1. Go firebase console.

  2. Click Authentication.

  3. Click SIGN-IN METHOD.

  4. Scroll down and check Authorized domains.

  5. Add your site address where you implement phone Authentication.

我遇到了一个非常相似的问题,但是单调性属性上有额外的上限和下限。我正在解决这样的问题(也许对您有帮助):

  1. 使用Scipy给出的信任区域约束算法。这为我们提供了一种处理矩阵曼纳中线性约束的方法:
  lb <= A.dot(x) <= ub

其中lb&amp;和ub是此约束问题的下部(上)边界,a是矩阵,代表线性约束问题。

  1. 矩阵的每一行a是一个线性术语,它定义了约束

  2. ,例如x [0]&lt; = x [1],那么这可以被转换为x [0] - x [1]&lt; = 0,它在线性约束矩阵a方面看起来像[1,-1 ,...],前提是上限向量在此级别上具有0个值(反之亦然,但无论哪种方式,至少具有下限或上限的一个,使此简单)

  3. 设置足够的这些不平等现象,同时将其中的几个合并到一个不平等可能会产生足够的矩阵来解决此问题。

希望这有点有帮助,它为我的问题做了工作。

I'm having a very similar problem but with additional upper and lower bounds on the monotonicity property. I'm tackling the problem like this (maybe it helps you):

  1. Using the Trust-Region Constrained Algorithm given by scipy. This provides us a way of dealing with linear constraints in a matrix-manner:
  lb <= A.dot(x) <= ub

where lb & and ub are the lower (upper) bounds of this constraint problem and A is the matrix, representing the linear constraint problem.

  1. every row of matrix A is a linear term which defines a constraint

  2. If, for example, x[0] <= x[1], then this can be transformed into x[0] - x[1] <= 0 which in terms of the linear constraint matrix A looks like this [1, -1,...], provided that the upper bound vector has a 0 value on this level of course (vice versa is also possible but either way, having at least one of both, lower or upper bound, makes this easy)

  3. Setting up enough of these inequalities and at the same time merging a couple of those into a single inequality may create a sufficient matrix to solve this.

Hope this helps a bit, It did the job for my problem.

用scipy施加单调性。

看起来OP的问题已通过此答案解决了: https://stackoverflow.com/a/a/72102209/88816585

使用servermiddleware很重要,并且它在nuxt.config.js文件中

export default {
  serverMiddleware: [
    { path: '/api', handler: '~/server-middleware/rest.js' },
  ],
}

It looks like OP's question was solved with this answer: https://stackoverflow.com/a/72102209/8816585

It was important to use serverMiddleware and it like that in the nuxt.config.js file

export default {
  serverMiddleware: [
    { path: '/api', handler: '~/server-middleware/rest.js' },
  ],
}

nuxt-无法获得API后端

您可以在C14-CER_MEAN之后使用LOC为选择所有列,然后分配,以下是一些没有loc> loc的替代方案,带有> iloc 一起:

 #select by position, position of C14-Cer_mean is count by get_loc
 df2 = df.iloc[-1, df.columns.get_loc('C14-Cer_mean'):]

 #select by position, from second column
 df2 = df.iloc[-1, 1:]

 #seelct by labels, last row by last index
 df2 = df.loc[df.index[-1],'C14-Cer_mean':]

 df.loc[:,'C14-Cer_mean':] = df.loc[:,'C14-Cer_mean':].div(df2)

print(df)
  Sample_name C14-Cer_mean C16-Cer_mean C18-Cer_mean C18:1-Cer_mean
0         1 1     0.305224     0.542487    66.428371      73.615348
1        1 10     0.814694     1.246165    73.802633       58.06458
2        1 13     0.556437     0.517383     50.55594       51.91374
3        1 14     0.314057     1.148754    56.165758      61.262175
4         1 5     0.499128     0.460814    40.182447      41.771061
5         1 6     0.300203     0.784066    47.359498      52.842018
6         1 9     0.395581     1.082055    54.019758      58.772952
7       Blank          1.0          1.0          1.0            1.0

You can use loc for select all columns after C14-Cer_mean and assign back, here are some alternatives without loc with iloc together:

 #select by position, position of C14-Cer_mean is count by get_loc
 df2 = df.iloc[-1, df.columns.get_loc('C14-Cer_mean'):]

 #select by position, from second column
 df2 = df.iloc[-1, 1:]

 #seelct by labels, last row by last index
 df2 = df.loc[df.index[-1],'C14-Cer_mean':]

 df.loc[:,'C14-Cer_mean':] = df.loc[:,'C14-Cer_mean':].div(df2)

print(df)
  Sample_name C14-Cer_mean C16-Cer_mean C18-Cer_mean C18:1-Cer_mean
0         1 1     0.305224     0.542487    66.428371      73.615348
1        1 10     0.814694     1.246165    73.802633       58.06458
2        1 13     0.556437     0.517383     50.55594       51.91374
3        1 14     0.314057     1.148754    56.165758      61.262175
4         1 5     0.499128     0.460814    40.182447      41.771061
5         1 6     0.300203     0.784066    47.359498      52.842018
6         1 9     0.395581     1.082055    54.019758      58.772952
