让按钮触发页面工作功能,创建一些您正在工作的指示器,触发 ajax 请求,当它返回时完成工作并隐藏指示器。无需转到代码后面。

Have the button trigger a page working function that creates some indicator that you are working, fire off the ajax request, and when it comes back finish the working and hide the indicator. No need to ever have to go to code behind.

我遇到了与 Yablargo 相同的问题,它说 valid 不是一个函数,所以我想出了这个:

对于提交按钮的 onclick 处理程序,我输入:

onclick="return $(this)。最接近('形式')。checkValidity();”

I was having the same issue Yablargo was having in that it was saying that valid is not a function, so I came up with this:

For the onclick handler of the submit button, I put this:

onclick="return $(this).closest('form').checkValidity();"

我有一些带有 Airplay 功能的应用程序,我不需要做任何花哨的事情。
不过我启用了自动播放。
moviePlayer.shouldAutoplay = YES;

尝试一下也许可以解决您的问题。

I have a few apps with airplay and I didn't have to do anything fancy.
However I enabled auto play.

Try it maybe it solves your issue.

造成这种情况的原因可能有很多,但是,您没有发布任何有用的详细信息,例如错误消息或引发的异常(如果有)。

检查 Windows 防火墙是否允许端口 1433 上的访问 - 这是失败的最可能原因,因为您使用的是 IP 地址而不是实例的名称。

我建议查看 http://connectionstrings.com 来检查您的连接字符串。

There could be many reasons for this, however, you didn't post any useful details such as error messages or what exception was thrown (if any).

Check that Windows Firewall allows access on port 1433 - this is the most likely reason for the failure, since you are using an IP address and not the name of the instance.

I suggest looking at http://connectionstrings.com to check your connection string.

除了@caseyB所说的(看评论)之外,我还必须改变活动的主题才能达到预期的效果。我认为这是 HoneyComb Xoom 上的问题,在手机上可能不会出现。
感谢大家看我的问题并提供帮助。

In addition to what @caseyB had to say (look at the comments), i had to change the theme of the activity to achieve the intended effect. I think this is an issue on HoneyComb Xoom and may not be seen on phones.

我也遇到过这种奇怪的情况。我所知道的是,早些时候我使用 Spring 版本 1.5.4 运行我的 spring 项目,后来在一个项目中我选择了版本 2.0.1。就在那时我收到了这个错误。当我访问POM并手动将Spring版本更改为1.5.4时,错误消失了。我的猜测是,maven会根据指定的Spring版本下载所需的JAR。如果您更改版本,如果这些 JAR 已经为以前的 Spring 版本下载,并且在 .m2 源文件夹中找到,maven 将不会下载 JAR,如 C: ->;用户-> “登录用户名”-> .m2 路径。

我再次做的是保持 Spring 版本不变(如 2.0.1),我打开了前面所说的问题视图,并通过访问 .m2 文件夹(问题视图中提到了 JAR 的路径)。然后我更新了maven,所有问题都消失了。

这就是我得出的结论,问题出在 .m2 文件夹中为以前的 Spring 版本下载的 JAR 上。

I too faced this strange situation. What I got to know is that, earlier I ran my spring projects with Spring version 1.5.4 and later for one project I chose version 2.0.1. That's when I got this error. When I visited POM and changed Spring version to 1.5.4 manually, the error was gone. What I guess is that, maven downloads the required JARs according to the Spring version specified. If you change the version, maven won't download JARs if those JARs are already downloaded for previous Spring version and found in .m2 source folder found as C: -> Users -> "Logged-In-User-Name" -> .m2 path.

What I did again was to keep the Spring version as it is (as 2.0.1), I opened the Problems view as said earlier and I deleted the JARs which were said as not found in the Problems view by visiting .m2 folder (the Paths were mentioned in the Problems view for were the JARs are). I then updated the maven and all problems were gone.

That's how I conclude that the problem was with JARs which were downloaded for the previous Spring versions in .m2 folder.

首先,我认为您提出的类型签名没有多大意义。给定一个应用列表 f [a] ,没有通用方法将其转换为 [fa] ——因此不需要 fa 类型的函数 -> ; f b 。为了保持理智,我们将该函数简化为 a ->; f b (将其转换为另一个是微不足道的,但前提是 f 是一个 monad)。

所以现在我们想要:

mapX :: (Applicative f) => (a -> f b) -> f [a] -> f [b]

现在立即想到的是traverse,它是mapM的泛化。遍历,专门用于列表:

traverse :: (Applicative f) => (a -> f b) -> [a] -> f [b]

关闭,但没有雪茄。同样,我们可以将 traverse 提升到所需的类型签名,但这需要一个 monad 约束:mapX f xs = xs >>= traverse f。

如果您不介意 monad 约束,这很好(事实上您可以使用 mapM 更直接地做到这一点)。如果您需要将自己限制在应用范围内,那么这应该足以说明为什么您提议的签名实际上不可能。

编辑:根据进一步的信息,我将如何开始解决根本问题。

-- your sketch
a = liftA sum $ mapX aux $ liftA2 neighbors (x!i) nbr 
   where aux :: f Int -> f Vector3
   -- the type of "liftA2 neighbors (x!i) nbr" is "f [Int]

-- my interpretation
a = liftA2 aux x v
    where
       aux :: VArray -> VArray -> VArray 
       aux xi vi = ...

如果你不能像那样写 aux —— 作为从某个时间点的位置和速度到加速度的纯函数,那么你就会遇到更大的问题......

这是一个关于原因的直观草图。流应用函子接受一个值,并随着时间的推移将其提升为一个值——一个值序列或值流。如果您可以随时间访问某个值,则可以派生它的属性。因此,速度可以用加速度来定义,位置可以用速度来定义,等等。伟大的!但现在您想根据位置和速度来定义加速度。也很棒!但在这种情况下,您不应该需要根据随时间变化的速度来定义加速度。你可能会问为什么?因为随时间变化的速度是加速度的开始。因此,如果您根据 dv 定义 a,并根据 integral(a) 定义 v,那么您'已经有一个闭环,并且您的方程没有正确确定 - 即使给定初始条件,也有无限多个解,或者根本没有解。

First, I don't think your proposed type signature makes much sense. Given an applicative list f [a] there's no general way to turn that into [f a] -- so there's no need for a function of type f a -> f b. For the sake of sanity, we'll reduce that function to a -> f b (to transform that into the other is trivial, but only if f is a monad).

So now we want:

mapX :: (Applicative f) => (a -> f b) -> f [a] -> f [b]

What immediately comes to mind now is traverse which is a generalization of mapM. Traverse, specialized to lists:

traverse :: (Applicative f) => (a -> f b) -> [a] -> f [b]

Close, but no cigar. Again, we can lift traverse to the required type signature, but this requires a monad constraint: mapX f xs = xs >>= traverse f.

If you don't mind the monad constraint, this is fine (and in fact you can do it more straightforwardly just with mapM). If you need to restrict yourself to applicative, then this should be enough to illustrate why you proposed signature isn't really possible.

Edit: based on further information, here's how I'd start to tackle the underlying problem.

-- your sketch
a = liftA sum $ mapX aux $ liftA2 neighbors (x!i) nbr 
   where aux :: f Int -> f Vector3
   -- the type of "liftA2 neighbors (x!i) nbr" is "f [Int]

-- my interpretation
a = liftA2 aux x v
    where
       aux :: VArray -> VArray -> VArray 
       aux xi vi = ...

If you can't write aux like that -- as a pure function from the positions and velocities at one point in time to the accelerations, then you have bigger problems...

Here's an intuitive sketch as to why. The stream applicative functor takes a value and lifts it into a value over time -- a sequence or stream of values. If you have access to a value over time, you can derive properties of it. So velocity can be defined in terms of acceleration, position can be defined in terms of velocity, and soforth. Great! But now you want to define acceleration in terms of position and velocity. Also great! But you should not need, in this instance, to define acceleration in terms of velocity over time. Why, you may ask? Because velocity over time is all acceleration is to begin with. So if you define a in terms of dv, and v in terms of integral(a) then you've got a closed loop, and your equations are not propertly determined -- either there are, even given initial conditions, infinitely many solutions, or there are no solutions at all.

windowsbase.dll 是 Windows Presentation Foundation 的一部分(与 Silverlight 有很多重叠)。要使用 windowsbase.dll 中的类型,您需要一个 WPF 应用程序(如果您不了解任何 WPF,则需要了解所有学习曲线)。

如果您想要 GUI 应用程序,那么 WPF 是一个不错的方法。

(否则:请用更多上下文更新问题。)

windowsbase.dll is part of Windows Presentation Foundation (which has a lot of overlap with Silverlight). To use types from windowsbase.dll you'll need a WPF application (with all the learning curve if you don't know any WPF).

If you want a GUI application then WPF is a good approach.

(Otherwise: please update the question with more context.)

这将创建一个全局变量isDragging,可以随时测试该变量以查看鼠标当前是否处于拖动模式,或者只是在没有单击任何按钮的情况下移动。

let isDragging = false;
document.addEventListener('mousemove', function(event) {
    if(event.buttons > 0) {
        isDragging = true;
    } else {
        isDragging = false;
    }
});

This creates a global variable isDragging which can be tested at any time to see if the mouse is currently in drag mode, or simply being moved around without any button being clicked.

let isDragging = false;
document.addEventListener('mousemove', function(event) {
    if(event.buttons > 0) {
        isDragging = true;
    } else {
        isDragging = false;
    }
});
