嗯嗯。打开并保存 web.config 就可以了。有人知道有什么更优雅的吗? :)

Hmmmm. Opening and saving web.config does the trick. Anyone know anything a little more elegant? :)

我认为你可以通过将change()放在点击处理程序中然后触发点击来使其适用于jQuery 1.4.4和1.6实现。

$('.myelement').click(function(){
 $('.myelement').change();   
 alert($(this).val());
});
$('.myelement').trigger('click');

看一下那里的简单示例。

I think you can make it work for both jQuery 1.4.4 and 1.6 implementations by putting change() within click handler and then triggering the click.

$('.myelement').click(function(){
 $('.myelement').change();   
 alert($(this).val());
});
$('.myelement').trigger('click');

Have a look there for simple example.

在较新版本中,jQuery .change() 事件是通过 .click() 触发的吗?

尝试所需的功能 - 请参阅此处:http://code.google.com/p/selenium/ wiki/ChromeDriver

所以我建议你在 @BeforeClass 函数中使用类似的东西:

 @BeforeClass
 public static void createAndStartService() {
  service = new ChromeDriverService.Builder()
    .usingChromeDriverExecutable(new File("path/to/my/chromedriver"))
  DesiredCapabilities capabilities = DesiredCapabilities.chrome();
  capabilities.setCapability("chrome.switches", Arrays.asList("--disable-web-security"));
  WebDriver driver = new ChromeDriver(capabilities);

顺便说一句,最好的方法是将 chromedriver.exe 存储在你的 maven /src 子目录中

Try the desiredCapabilities - see here: http://code.google.com/p/selenium/wiki/ChromeDriver

So I would suggest you using something like this in your @BeforeClass function:

 @BeforeClass
 public static void createAndStartService() {
  service = new ChromeDriverService.Builder()
    .usingChromeDriverExecutable(new File("path/to/my/chromedriver"))
  DesiredCapabilities capabilities = DesiredCapabilities.chrome();
  capabilities.setCapability("chrome.switches", Arrays.asList("--disable-web-security"));
  WebDriver driver = new ChromeDriver(capabilities);

BTW best way is to store chromedriver.exe in your maven /src subdirectory

您可以查看 jsch,它是 Java ssh 客户端库。 http://www.jcraft.com/jsch/

但是,有一些非常好的 ssh 客户端已经有了(ConnectBot),所以也许你可以构建其他东西?

You can look at jsch which is Java ssh client library. http://www.jcraft.com/jsch/

However, there are some really good ssh clients out there already (ConnectBot), so may be you can build something else?

您不需要继承,因为默认情况下 Enum 的基本类型是 int。

http://msdn.microsoft.com/en-我们/library/sbbt4032(v=vs.71).aspx

base-type (Optional)
The underlying type that specifies the storage allocated for each enumerator. It can be one of the integral types except char. The default is int.

You do not need to inherit as the base type of an Enum is by default, int.

不,没有。闭包中的 this 值与闭包定义的范围内的值不同,因此这是使其更清晰的唯一方法是在对象级别上定义它,因此至少每个对象只需执行一次,看起来您已经在这样做了。

编辑:

删除“不,没有”,因为 bind 是一个有效的替代方案,并且有可比性实现(请参阅其他答案)。虽然我个人认为 var self = this; 更干净,您只需要为每个对象定义一次,但此时这是一个偏好问题。

No, there isn't. The value of this will be different in the closure than it is in the scope that the closure is defined so the only way to make it cleaner is to define it on an object level so at least you only have to do it once per object, which it looks like you are already doing anyway.

Edit:

Strike out the "No there isn't" because bind is a valid alternative and there are comparability implementation (see other answer). Although I personally think var self = this; is cleaner and you only need to define it once per object but it is a matter of preference at this point.

我有问题。这是因为使用 ser.read 告诉 Ruby 永远继续读取,而 Ruby 永远不会停止读取,从而挂起脚本。解决方案是仅读取特定数量的字符。

例如:

ser.readline(5)

I had the problem to. It's because using ser.read tells Ruby to keep reading forever and Ruby never stops reading and thus hangs the script. The solution is to only read a particular amount of characters.

So for example:

ser.readline(5)

使用 Ruby 从串行端口读取数据

Cookie 用于识别会话。访问任何使用 cookie 的网站,然后拉出 Chrome 检查元素,然后拉出网络或 FireBug(如果使用 Firefox)。

您可以看到有一个标头发送到服务器并且也收到了称为 Cookie 的标头。通常它包含一些可在服务器上用来识别会话的个人信息(如 ID)。这些 cookie 保留在您的计算机上,您的浏览器负责将它们仅发送到用其标识的域。

如果没有 cookie,那么您将通过 GET 或 POST 发送每个请求的唯一 ID。 Cookie 类似于静态 ID,会在您的计算机上保留一段时间。

会话是服务器上与 cookie 信息关联的一组信息。如果您使用 PHP,您可以检查 session.save_path 位置并实际“查看会话”。它们要么是服务器文件系统上的文件,要么是数据库中的文件。

Cookie 的屏幕截图

Cookies are used to identify sessions. Visit any site that is using cookies and pull up either Chrome inspect element and then network or FireBug if using Firefox.

You can see that there is a header sent to a server and also received called Cookie. Usually it contains some personal information (like an ID) that can be used on the server to identify a session. These cookies stay on your computer and your browser takes care of sending them to only the domains that are identified with it.

If there were no cookies then you would be sending a unique ID on every request via GET or POST. Cookies are like static id's that stay on your computer for some time.

A session is a group of information on the server that is associated with the cookie information. If you're using PHP you can check the session.save_path location and actually "see sessions". They are either files on the server filesystem or backed in a database.

是的,您可以在一个中心位置更改此设置:XML 文件。

但是,不幸的是,价值数十亿美元的软件 QC 无法显示甚至无法让您在 QTP 内编辑 XML -- < strong>你必须下载它,编辑下载的副本(使用记事本或其他工具),然后再次上传。

在QTP中,更改对于上传后打开的所有测试都是可见的。

如果您使用版本控制,则必须签出、下载、编辑、保存、上传、签入 XML 以使更改全局生效。

Yes, you can change this in one central location: The XML file.

However, the multi-zillion-dollar software QC unfortunately is unable to display or even let you edit the XML from within QTP -- you have to download it, edit the downloaded copy (with notepad, or whatever), and upload it again.

In QTP, the change is visible for all tests opened after the upload.

If you are using version control, you must check-out, download, edit, save, upload, check-in the XML to make the change effective globally.

SELECT a.*
FROM attributes a, products_to_attributes  b
WHERE a.aid = b.aid
AND b.pid = 1

它与 tofutim 的答案基本上相同,但不使用 INNER JOIN 语法。

SELECT a.*
FROM attributes a, products_to_attributes  b
WHERE a.aid = b.aid
AND b.pid = 1

it's basically the same answer as tofutim, but without using the INNER JOIN syntax.

通常最好提前声明文档和 IDE 自动完成功能的属性。然而,这不是 PHP 所需要的。

另外,除非您担心 PHP4(我希望不会),否则使用“public”而不是“var”更合适。

It's usually better to declare the properties beforehand for documentation and IDEs' auto-complete functionality. However, it's not something that's required by PHP.

Also, unless you are worried about PHP4 (I hope not), it's more proper to use "public" instead of "var".
