$host.ui.prompt 正如其名称所示,特定于主机实现。 PowerGui 实现了基于 GUI 的自定义主机/提示符。控制台上的默认提示是您看到的文本提示。

也许你想看这里:http:// www.windowsitpro.com/blog/powershell-with-a- Purpose-blog-36/scripting-languages/getting-input-and-inputboxes-in-powershell-137449

在这里:

http://technet.microsoft.com/en-us/library/ff730941.aspx

The $host.ui.prompt like the name says, is specific to the host implementation. PowerGui have impemented a custom host / prompt which is GUI based. The default prompt on the console is the text one that you see.

Maybe you want to look here: http://www.windowsitpro.com/blog/powershell-with-a-purpose-blog-36/scripting-languages/getting-input-and-inputboxes-in-powershell-137449

如果子类定义了构造函数,则不会隐式调用父构造函数。为了运行父构造函数,需要在子构造函数中调用parent::__construct()。

参见此处

Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct() within the child constructor is required.

See here

如果子类没有定义构造函数,可以直接使用超类的构造函数吗?

如果您需要的只是到处进行一些小编辑,像 geany 这样的专门编辑器会为您提供更好的服务。

如果你想制作小程序,在开始小程序时,手动使用编译器的 geany + shell 会更简单。

您编辑代码,保存,然后在控制台上使用 gcc micode.c -o micode.exe 即可。

You'll be better served by a dedicated editor like geany if all you need is some little edits here and there.

If you want to make small programs, geany + the shell using your compiler manually is simpler when starting small.

You edit your code, save, then gcc micode.c -o micode.exe on the console and your ready.

Shibboleth 被许多机构使用,但绝不是全部。许多人使用雅典、代理或 IP 识别等。

据我所知,用户的电子邮件地址并不直接与 Shib 系统绑定。当用户尝试访问受 Shibboleth 保护的资源时,他们会被带到其机构的登录页面以进行身份​​验证。他们可能会输入电子邮件地址进行身份验证,也可能会输入用户名,可能会根据 IP 地址或其他内容自动登录。

成功登录后,该机构确实会通过 Shib 数据传输发回隶属关系,例如 [email protected ] 但这不一定是电子邮件用于登录的用户地址。我想他们可以发送该信息,但它尚未在我开发的系统中使用。

Shibboleth 通常用于检查用户是否来自已购买受保护资源访问权限的机构,而不是识别该机构的特定用户,因此不需要用户的电子邮件。

不确定这是否有帮助: http:// /middleware.internet2.edu/eduperson/docs/internet2-mace-dir-eduperson-200806.html#eduPersonAffiliation

Shibboleth is used by many institutions, but by no means all. Many use Athens, proxies or IP recognition, among other things.

As far as I am aware, a user's email address is not tied directly to the Shib system. When a user tries to access a Shibboleth-protected resource they are taken to their institution's login page to authenticate themselves. They might enter their email address to authenticate or they might enter a username, they might be auto logged-in based on their IP address, or something else.

The institution does send back an affiliation through Shib data transfer upon successful login, something like [email protected] but this is not necessarily the email address the user used to login. I guess they could send that but it has not been used in system's I've worked on.

Shibboleth is commonly used to check that the user is from an institution that has purchased access to a protected resource rather than identifying a particular user from that institution so the user's email isn't needed.

Not sure if this helps at all: http://middleware.internet2.edu/eduperson/docs/internet2-mace-dir-eduperson-200806.html#eduPersonAffiliation

您的 SQL 格式错误。正确的问题更有可能得到正确的答案。我将把你的表命名为 A 和 B。

SELECT * FROM B WHERE B.document_id IN (SELECT DISTINCT A.document_id FROM A)

Your SQL is malformed. A correct question is more likely to retrieve a correct answer. I'll name your table A and B.

SELECT * FROM B WHERE B.document_id IN (SELECT DISTINCT A.document_id FROM A)

如果我明白你想说的话,你所要做的就是将 create() 方法中的代码更改为类似于 make(),使 < code>create() 具有 make() 签名的公共方法,并从类中删除 make() 方法:

public function create($table_array)  
{  
    foreach($table_array as $table) {
        $type = $table["type"];

        switch ($type)   
        {  
            case "credentials":  
                database::query('CREATE TABLE credentials(id INT NOT NULL AUTO_INCREMENT, flname VARCHAR(60), email VARCHAR(32), pass VARCHAR(40), PRIMARY KEY(id))');  
                break;  
            case "booomark":  
                database::query('CREATE TABLE boomark(name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT)');  
                break;  
            case "tweet":  
                database::query('CREATE TABLE tweet(time INT, fname VARCHAR(32), message VARCHAR(128), email VARCHAR(64))');  
                break;  
            default:  
                throw new Exception('Invalid Table Type');  
        }
    }
}

If I have understood what you want to say, all you have to do is change the code in the create() method to be similar to the make(), making create() a public method with the make() signature and removing the make() method from the class:

public function create($table_array)  
{  
    foreach($table_array as $table) {
        $type = $table["type"];

        switch ($type)   
        {  
            case "credentials":  
                database::query('CREATE TABLE credentials(id INT NOT NULL AUTO_INCREMENT, flname VARCHAR(60), email VARCHAR(32), pass VARCHAR(40), PRIMARY KEY(id))');  
                break;  
            case "booomark":  
                database::query('CREATE TABLE boomark(name VARCHAR(64), url VARCHAR(256), tag VARCHAR(256), id INT)');  
                break;  
            case "tweet":  
                database::query('CREATE TABLE tweet(time INT, fname VARCHAR(32), message VARCHAR(128), email VARCHAR(64))');  
                break;  
            default:  
                throw new Exception('Invalid Table Type');  
        }
    }
}

您的意思是 ModelBinder 没有将“完整”对象传递给您的控制器?

这不会自动为您完成。 ModelBinder 不使用底层集合。您必须自己创建这个集合。在控制器中使用 FormCollection 作为参数并迭代它以创建集合。

这篇文章展示了如何通过 FormCollection 进行枚举:
如何在 ASP.NET MVC 中枚举表单集合?

You mean the ModelBinder is not passing a 'full' object to your controller?

That will not be done automatically for you. Underlying collections are not used by the ModelBinder. You will have to create this collection by yourself. Use FormCollection in your controller as a parameter and iterate through it to create the collection.

This post is showing how to enumerate through the FormCollection:
How can a formcollection be enumerated in ASP.NET MVC?

这可能是您的解决方案。

您可以将数据聚合到按小时或天分组的中间存储。分组功能将工作得非常快,因为您需要对少量记录进行分组,并且插入也会很快。精确决策由您决定。

它比自相关指数算法更好,因为您可以更轻松地理解您计算的内容,并且不需要每一步都进行数学计算。

对于最后学期的数据,您可以使用记录数量有限的上限集合。它们受到一些数据库(例如 MongoDB)的本地支持。

It may be solution for you.

You can aggregate data to intermediate storage grouped by hour or day. Than grouping function will work very fast, because you will need to group small amount of records and inserts will be fast as well. Precision decisions up to you.

It can be better than auto-correlated exponential algorithms because you can understand what you calculate easier and it doesn't require math each step.

For last term data you can use capped collections with limited amount of records. They supported natively by some DBs for example MongoDB.

这就是您的代码所说的:

  1. 单击文本时,创建一个新的输入元素,提交按钮和表单。
  2. 在模糊时隐藏输入元素(而不是提交按钮)

因此,当您第一次单击“提交”时,它实际上会触发模糊事件并隐藏输入。

此外,您的旧文本不会重新显示,因为您使用 .prev 来获取它。这会选择前一个相邻的同级元素,但由于输入元素位于表单中,因此另一个元素不是同级元素。

这个小提琴应该让问题变得更加明显。请注意初始警报如何不检索文本 FOO。另请尝试单击“提交”按钮。

http://jsfiddle.net/uNbYu/8/

This is what your code says:

  1. When text is clicked, create a new input element, submit button and form.
  2. On blur hide the input element (not the submit button)

So when you click submit the first time it is actually firing the blur event and hiding the input.

Also, your old text is not being reshown because you use .prev to get it. This select previous adjacent sibling, but because the input element is in a form, the other element is not a sibling.

This Fiddle should make what is wrong more obvious. Note how the initial alert does not retrieve the text FOO. Also try and click submit button.

http://jsfiddle.net/uNbYu/8/

为什么在我的示例中,提交按钮仅在按两次时才起作用?

我可以告诉你的一件事是,在 IE 中,在标记中出现较低的元素(但不是同一父元素的子元素)将始终具有较高的 z-index。
有两种可能的解决方案:

1) 重新编写代码,使其不依赖 z-index(absolute 定位元素应始终出现在 relative之上无论如何都是静态的)

2)物理移动文档正文底部的定位 div。

此外,您的 maxZ 计算看起来笨拙且混乱。您确定 max() 确实适用于任意值数组(即元素数量超过 2)吗?更具体地说,是在 IE 中。

如果您需要更多帮助,请发布您的标记。

One thing I can tell you is that in IE an element appearing lower in the markup (but not a child of the same parent) will always have higher z-index.
There are two possible solutions to that:

1) rework you code to not rely on z-index (absolute positioned elements should always appear over top of the relative or static ones anyway)

2) physically move your positioned div at the bottom of the document body.

Also your maxZ calculations looks awkward and messy. Are you sure max() actually works with arbitrary array of values (i.e. with number of elements more than 2)? In IE, more specifically.

If you need more help, post your markup.

当然,这会调用未定义的行为,与平台相关,假设代码地址与 int 大小相同,等等。

Of course, this invokes undefined behavior, is platform-dependent, assumes that code addresses are the same size as int, etc, etc.
