如果需要多个观察者,则需要每次打电话观看:

watch(() => form.image, () => {
    console.log(form.image)
})
watch(() => form.body, () => {
    console.log(form.body)
})

如果您需要的是观察者观看两个人,则应:

watch([() => form.image, () => form.body], 
([newImage, newBody], [prevImage, prevBody]) => {
    console.log(form.body, form.image)
})

如果我们以该答案为例: https://stackoverflow.com/a/45853349/8126784 来自您链接的问题

You need to call watch each time if you need multiple watchers:

watch(() => form.image, () => {
    console.log(form.image)
})
watch(() => form.body, () => {
    console.log(form.body)
})

if what you need is a watcher to watch the two then :

watch([() => form.image, () => form.body], 
([newImage, newBody], [prevImage, prevBody]) => {
    console.log(form.body, form.image)
})

if we take example on that answer : https://stackoverflow.com/a/45853349/8126784 from the question you linked

(编辑): Resolution_Hint 太小(〜1E-17)触发了Drake中的错误。 20 的结果

这是 resolution_hint = peg_circumference / ://i.sstatic.net/oiyqs.png“ alt =”孔中的hydro弹性钉>

(原始答案):

您有一个我可以用来重现错误的公共分支吗?

我的第一个怀疑是您的 resolution_hint 太大了。在水力启示中使用的所有原始形状均给予内部网格表示,并且该参数控制着网格的粗糙性。有了非常大的分辨率提示,气缸的近似最终可能是一个盒子。尝试较小的分辨率提示。

如果那不起作用:

您是否使用 drake的固定缸或网格:decrare_convex 标签?我的另一个怀疑是,将钉子网或孔网眼中某些面的方向逆转。

我们依靠一种预期,即用作水力弹性几何形状的网格具有一致且向外取向的面部正常。

(EDIT): resolution_hint is too SMALL (~1e-17) triggering a bug in Drake. Here is the result with resolution_hint = peg_circumference / 20:

hydroelastic peg in hole

(Original Answer):

Do you have a public branch that I can use to reproduce the error?

My first suspicion is that your resolution_hint is too large. All primitive shapes used in hydroelastics are given an internal mesh representation and this parameter controls the coarseness of the mesh. With a very large resolution hint, the approximation of the cylinder can end up being a box. Try a smaller resolution hint.

If that doesn't work:

Are you using a cylinder primitive for your peg or a mesh with the drake:declare_convex tag? My other suspicion is that the orientation of some of the faces in either the peg mesh or the hole mesh are reversed.

We rely on an expectation that meshes used as hydroelastic geometries have consistent and outwardly orientated face normals.

基本上,您需要将PIP安装的路径添加到路径系统变量中。

第一个选项

通过修改Pyton安装来下载PIP。

步骤1-打开应用程序&amp;功能

步骤2-查找python并单击

步骤3-按修改

步骤4-选择 pip

步骤5-选择<代码>将Python添加到环境变量并安装所有

将安装 pip 并同时添加 python pip

第二选项

默认情况下, pip c:\ python34 \ scripts \ pip

中安装在您的路径变量遵循该步骤。

步骤1-搜索环境变量并打开编辑系统环境变量

步骤2-开放环境变量...

步骤3-查找您的 path 变量和选择编辑

步骤4-将位置粘贴到您的 pip 安装(默认情况下,它是 c:\ python34 \ scripts \ pip

Basiclly, You need to add the path of your pip installation to your PATH system variable.

First Option

Download pip by modifying the Pyton Installation.

Step 1 - Open Apps & Features

Step 2 - Find Python and click on it

Step 3 - Press Modify

Step 4 - Select pip

Step 5 - Select Add Python to environment variables and install everything

This will install pip and add both, Python and pip to your envirnoment variables.

Second Option

By default, pip is installed in C:\Python34\Scripts\pip

To add the path of your pip installation to your PATH variable follow theese steps.

Step 1 - Search for environment variables and open Edit the system environment variables

Step 2 - Open Environment Variables...

Step 3 - Find your PATH variable and select Edit

Step 4 - Paste the location to your pip installation (By default, it's C:\Python34\Scripts\pip)

等待功能

您需要等待该功能。 “打电话” Coroutine实际上什么都不做。

async def fun(fun_word):
    ctx.send(fun_word)
@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await fun(word)

即时进行上下文(尽管不完整)

请参阅文档: https://discordpy.readthedocs.io/en/latest/ext/command/commands/api.html?highlight = context #context#discord.ext.commands.commands.context < /a>。您可以从给出的消息中删除自己的上下文。

async def fun(ctx, fun_word):
    ctx.send(fun_word)
@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await fun(commands.Context(message=message), word)

通常发送消息

这是实现您似乎想做的事情的最干净的方法。而不是强制 CTX ,只需通过 Message.Channel 正常发送消息。实际上, ctx.send 实际上只是对此的别名。

@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await message.channel.send(word)

Await the function

You need to await the function. "Calling" a coroutine actually does nothing.

async def fun(fun_word):
    ctx.send(fun_word)
@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await fun(word)

Making context on the fly (albeit incomplete)

See the docs: https://discordpy.readthedocs.io/en/latest/ext/commands/api.html?highlight=context#discord.ext.commands.Context. You can make your own context off the message given.

async def fun(ctx, fun_word):
    ctx.send(fun_word)
@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await fun(commands.Context(message=message), word)

Send the message normally

This is the cleanest way of achieving what you appear to want to do. Rather than forcing ctx, just send the message normally through message.channel. In fact, ctx.send is actually just an alias to this.

@client.event
async def on_message(message):
    msg = message.content
    if msg == "pancake":
        await message.channel.send(word)

如何将CTX参数传递给拥有函数?

您的实现

在每个复选框上看起来都不错,是的,当然会更改您的根数据,并且

可以使用React.Memo

使用MEMO会导致RECT会跳过组件,如果如果是启用组件 ,则可以将所有子组件恢复到所有子组件,但是您可以控制子部件的重新租用。它的道具没有改变。

这可以提高性能。
检查此信息以获取详细说明

https://reaeactjs.s.orgg/docs/reaeact-api。 html#reactmemo

https://www.w3schools.com/react/react_memo.asp

请注意:React usememo和React备忘录不一样;

Your implementation looks fine

On every checkbox change yes of course it will change your root data and it will rerender all the child components

But you can control re-renders of child components using React.memo

Using memo will cause React to skip rendering a component if its props have not changed.

This can improve performance.
Check this for the detailed explanation

不久前我也面临着类似的问题。
对于更好的答案,我应该阅读代码,但我可以告诉您应该在哪里开始寻找问题。
这可能是因为您的页面中有一个规则,例如“ Overflow-Y:Auto”,并且它的父母本身大于当前页面巨头。

.container1 {
  background-color: red;
  height: 10000px;
  width: 100%;
}
.container2 {
  background-color: blue;
  height: 100vh;
  width: 100%;
  overflow-y: auto;
}

.container3 {
  background-color: green;
  height: 10000px;
  width: 50px;
}
<div class="container1">
  <div class="container2">
    <div class="container3">
    
    </div>
  </div>
</div>

我制作了一个快速片段,您可以执行以更好地查看正在发生的事情。

希望这可以帮助您找到问题。

I have faced a similar problem a while ago.
For a better answer i should read the code but i can tell you where you should start to look for the problem.
This is probably happening because of a div in your page that has a rule such as "overflow-y: auto" and it's parent is itself bigger than the current page heigth.

.container1 {
  background-color: red;
  height: 10000px;
  width: 100%;
}
.container2 {
  background-color: blue;
  height: 100vh;
  width: 100%;
  overflow-y: auto;
}

.container3 {
  background-color: green;
  height: 10000px;
  width: 50px;
}
<div class="container1">
  <div class="container2">
    <div class="container3">
    
    </div>
  </div>
</div>

I made a quick snippet you can execute to see better what is happening.

I hope this helps you to find the problem.

您应该在数据模型中添加一个布尔属性,例如 IseNabled ,并将其绑定到复选框

dataitem.cs

class DataItem : INotifyPropertyChanged
{
  // Let property raise the INotifyPropertyChanged.PropertyChanged event
  public bool IsEnabled { get; set; }
}

mainwindow.xaml < /strong>

<DataGrid ItemsSource="{Binding DataItems}">
  <DataGrid.RowStyle>
    <Style TargetType="DataGridRow">
      <EventSetter Event="PreviewMouseDoubleClick"
                   Handler="OnDataGridRowPreviewMouseDoubleClick" />
    </Style>
  </DataGrid.RowStyle>

  <DataGrid.Columns>
    <DataGridTemplateColumn Header="Choice">
      <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
          <CheckBox IsChecked="{Binding IsEnabled}" />
        </DataTemplate>
      </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
    </DataGridColumns>
</DataGrid>

mainwindow.xaml.cs

private void OnDataGridRowPreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
  var row = sender as DataGridRow;
  (row.Item as DataItem).IsEnabled = true;
}

You should add a boolean property like IsEnabled to your data model and bind it to the CheckBox:

DataItem.cs

class DataItem : INotifyPropertyChanged
{
  // Let property raise the INotifyPropertyChanged.PropertyChanged event
  public bool IsEnabled { get; set; }
}

MainWindow.xaml

<DataGrid ItemsSource="{Binding DataItems}">
  <DataGrid.RowStyle>
    <Style TargetType="DataGridRow">
      <EventSetter Event="PreviewMouseDoubleClick"
                   Handler="OnDataGridRowPreviewMouseDoubleClick" />
    </Style>
  </DataGrid.RowStyle>

  <DataGrid.Columns>
    <DataGridTemplateColumn Header="Choice">
      <DataGridTemplateColumn.CellTemplate>
        <DataTemplate>
          <CheckBox IsChecked="{Binding IsEnabled}" />
        </DataTemplate>
      </DataGridTemplateColumn.CellTemplate>
    </DataGridTemplateColumn>
    </DataGridColumns>
</DataGrid>

MainWindow.xaml.cs

private void OnDataGridRowPreviewMouseDoubleClick(object sender, MouseButtonEventArgs e)
{
  var row = sender as DataGridRow;
  (row.Item as DataItem).IsEnabled = true;
}

双击相应的行时,请在datagrid中检查复选框

XARGS 具有 -n 选项,该选项可用于分裂单弦输入。
但是我注意到,使用 -i -n1 一起破坏了其分裂行为(无引用的空白不终止输入项目 - man xargs )。
因此,除了使用 tr 之外,打破线路的另一种方法是将定界符通过 xargs 带有 -d
另外,您需要将 -n 添加到 echo 才能删除tawning newline,您将其视为 $'\ n'\ n'(并且它' LL随后的管道中断):

echo -n "a b c" | xargs -d " " -I% echo letter_%

或者您可以在管道中插入另一个XARG:

echo -n "a b c" | xargs -n1 | xargs -I% echo letter_%

xargs has -n option which is someway usable for splitting one-string input.
But I noticed, that using -I together with -n1 destroys its splitting behavior (unquoted blanks do not terminate input items - man xargs).
So another way to break a line besides using tr is explicitly passing delimiter to xargs with -d.
Also you will need to add -n to your echo to remove trailing newline, that you see as $'\n' (and it'll break subsequent piping):

echo -n "a b c" | xargs -d " " -I% echo letter_%

or you can just insert another xargs in your pipe:

echo -n "a b c" | xargs -n1 | xargs -I% echo letter_%

Xargs按空间拆分字符串

第三列只是表明船舶日期处于正确的一天。它看起来有所不同,因为日期是澳大利亚人(dd/mm/yyyy),而不是美国人(mm/dd/yyyy),但这对于该功能起作用并不重要。

船舶日期列中的功能:

=IF(OR(TEXT(A8,"dddd")="Tuesday",TEXT(A8,"dddd")="Wednesday",TEXT(A8,"dddd")="Thursday",TEXT(A8,"dddd")="Friday"),A8-WEEKDAY(A8,3),A8-WEEKDAY(A8+2,2))


船舶日期(包括标头)= b7:b20

说明

  • 将日期(dd/mm/yyyy)转换为漫长的一天(例如星期一)的

崩溃

  • 文本(值,格式化_text):如果一天是星期二,星期二,星期三,星期四, ,或周五,
  • 然后返回该周的日期,
  • 其他星期一还返回周五的那几周的日期

The third column is just to show that the ship dates are on the correct day. It looks different because the dates are Australian (DD/MM/YYYY) rather than American (MM/DD/YYYY), but that shouldn't matter for the function to work.

The function in the Ship Date column:

=IF(OR(TEXT(A8,"dddd")="Tuesday",TEXT(A8,"dddd")="Wednesday",TEXT(A8,"dddd")="Thursday",TEXT(A8,"dddd")="Friday"),A8-WEEKDAY(A8,3),A8-WEEKDAY(A8+2,2))

enter image description here

Need By Date (including header) = A7:A20
Ship Date (including header) = B7:B20

Explanation

  • TEXT(value, format_text): this is used to convert the date (DD/MM/YYYY) to the long day (e.g. Monday)

Breakdown

  • IF the day is Tues, Wed, Thurs, or Fri
  • THEN return the date of that weeks Monday
  • ELSE return the date of that weeks Friday

>方法可以接受系列作为其第一个参数,因此您可以将其传递给 end_daily_count 列的移位版本。假设您可以在不同的 id s上共享数据:

df['beginning_daily_count'] = df['beginning_daily_count'].fillna(df['end_daily_count'].shift())

print(df)
   id  beginning_daily_count  end_daily_count  foils
0   1                   30.0               33      0
1   1                   33.0               37      0
2   1                   37.0               46      0
3   1                   46.0               52      0
4   1                   52.0               33      0
5   2                    7.0                7      0
6   2                    1.0                1      0
7   2                    1.0                2      1
8   2                    2.0                3      1

The DataFrame.fillna method can accept a series as its first argument, so you can pass it a shifted version of your end_daily_count column. Assuming you are OK with potentially sharing data across different ids:

df['beginning_daily_count'] = df['beginning_daily_count'].fillna(df['end_daily_count'].shift())

print(df)
   id  beginning_daily_count  end_daily_count  foils

如何从另一列的值中正向填充一个列的零值?

而不是这样:

Sheet.format(“ r”,{“ numberFormat”:{“ type”:“ number”}})

尝试以下操作:

sheet.format(“ r”,{ “ numberFormat”:{“ type”:“ number”,“模式”:“#,## 0”}})

当您不知道如何使用客户端库格式化某物时,我建议您推荐什么使用Google API获取当前格式。

例如,您的单元格具有正确的数字格式。

然后使用此 api

spreadsheetId = Your spreadsheet ID
ranges = Your Cell reference goes here
fields = *

执行它,然后您会看到的结果:

      "data": [
        {
          "startRow": x,
          "startColumn": x,
          "rowData": [
            {
              "values": [
                {
                  "userEnteredValue": {
                    "numberValue": xxxxxxxxx
                  },
                  "effectiveValue": {
                    "numberValue": 950101
                  },
                  "formattedValue": "950,101",
                  "userEnteredFormat": {
                    "numberFormat": {
                      "type": "NUMBER",
                      "pattern": "#,##0"
                    }

这就是您使用的内容:

                    "numberFormat": {
                      "type": "NUMBER",
                      "pattern": "#,##0"

Instead of this:

sheet.format("R", { "numberFormat": { "type": "NUMBER" }})

Try this:

sheet.format("R", { "numberFormat": { "type": "NUMBER","pattern": "#,##0" }})

What I recommend when you don't know how to format something using a client library is to get its current format using the Google API.

E.g. You have a cell with the correct format of the numbers as you desire.

Then using this API you fill it out as follows:

spreadsheetId = Your spreadsheet ID
ranges = Your Cell reference goes here
fields = *

Execute it and then the results you'll see:

      "data": [
        {
          "startRow": x,
          "startColumn": x,
          "rowData": [
            {
              "values": [
                {
                  "userEnteredValue": {
                    "numberValue": xxxxxxxxx
                  },
                  "effectiveValue": {
                    "numberValue": 950101
                  },
                  "formattedValue": "950,101",
                  "userEnteredFormat": {
                    "numberFormat": {
                      "type": "NUMBER",
                      "pattern": "#,##0"
                    }

And this is what you'll use:

                    "numberFormat": {
                      "type": "NUMBER",
                      "pattern": "#,##0"
