Jquery 就可以了。

首先,构建一个普通表单,为

标记指定一个 id,例如 #someform,并为提交按钮指定一个 id,例如 #somebutton< /代码>。

然后将处理程序绑定到#someform:

$('#someform').submit(function(){
    var params=$(this).serialize();
    //here you submit params using $.post
    document.selectElementById('somebutton').disabled=true;
    return false;
})

无论有没有 js 支持,它都可以工作。

Jquery will do just fine.

First you build a normal form, give the <form> tag an id, say #someform, and an id to the submit button, say #somebutton.

Then you bind an handler to #someform:

$('#someform').submit(function(){
    var params=$(this).serialize();
    //here you submit params using $.post
    document.selectElementById('somebutton').disabled=true;
    return false;
})

It will work with or without js support.

如果您上传的视频/图像较小,值可能会相同。您可以通过上传大小超过 70MB 的视频来检查并检查您的加载值和总计值,它应该为您提供不同的总计值和加载值

Values might be same if your uploaded video/image size is small. You can check by uploading video of size more than 70MB and check your loaded and total values, it should give you different values in total and loaded

不,文本框不会有相同的 ID。因为它们位于不同的用户控件中,所以它们将被分配两个不同的ClientID。

您可以通过在浏览器中查看页面的源代码来查看控件的 ID。 ClientID 将如下所示:ctl00_ContentBody_tb1_TextBox1

No, the TextBoxes will not have the same ID. Because they are in different user controls, they will be assigned two different ClientIDs.

You can see the IDs of the controls by viewing the source of the page in the browser. The ClientID will look something like this: ctl00_ContentBody_tb1_TextBox1

是否可以在页面中多次使用同一个用户控件?

您是否检查过 AppFabricCachingService 登录是否具有对 DistributedCacheService.exe.config 的读取权限?

就我而言,我使用的是 XML 提供程序,并且有一个名为“CacheConfig”的配置共享。我的服务器未加入域,因此我为缓存主机配置了本地“AppFabric”用户。我正在使用 PowerShell 编写配置脚本:

Register-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric" -CachePort 22233 -ClusterPort 22234  -ArbitrationPort 22235 -ReplicationPort 22236 -HostName MY-HOST
Add-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric"
#...
Start-CacheCluster
#...

当我运行脚本时,Start-CacheCluster 语句失败,并出现与您的问题相同的访问被拒绝错误。然后,我检查了 AppFabricCachingService 登录,发现它已设置为 NETWORK SERVICE。检查C:\Windows\System32\AppFabric\DistributedCacheService.exe.config上的文件权限时,发现AppFabric用户有读取权限,但没有NETWORK权限服务。这向我表明 Register-CacheHostAdd-CacheHost 小程序假定缓存主机帐户和服务帐户相同。

就我而言,我为NETWORK SERVICE文件添加了读取权限,这解决了问题。

Have you checked that the AppFabricCachingService logon has read access to DistributedCacheService.exe.config?

In my case, I am using an XML provider and have a config share named "CacheConfig". My server is not joined to a domain so I have configured a local "AppFabric" user for the cache host. I am using PowerShell to script the config:

Register-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric" -CachePort 22233 -ClusterPort 22234  -ArbitrationPort 22235 -ReplicationPort 22236 -HostName MY-HOST
Add-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric"
#...
Start-CacheCluster
#...

When I ran the script the Start-CacheCluster statement failed with the same access denied error as in your question. I then checked the AppFabricCachingService logon and found it was set to NETWORK SERVICE. When I checked the file permissions on C:\Windows\System32\AppFabric\DistributedCacheService.exe.config, I found that there was a read permission for the AppFabric user, but no permissions for NETWORK SERVICE. This indicates to me that the Register-CacheHost or Add-CacheHost applet assumes that the cache host account and the service account will be the same.

In my case I added a read permission to the file for NETWORK SERVICE and that fixed the problem.

显然,您还没有为您的视图提供 id。

<ImageView android:id="@+id/my_view_id"
    android:src="@drawable/img23"
    android:layout_height="fill_parent"  
    android:layout_width="fill_parent"
    android:onClick="myClickHandler">

Obviously, you haven't given an id to your View.

<ImageView android:id="@+id/my_view_id"
    android:src="@drawable/img23"
    android:layout_height="fill_parent"  
    android:layout_width="fill_parent"
    android:onClick="myClickHandler">

imageview onClickHandler 将其 id 指定为 -1

您可以使用 ViewerState 属性指定过滤器。

它具有非常具体的语法,可以在此处找到< /a>.

You can specify filters by using the ViewerState property.

It has a very specific syntax, which can be found here.

您可以在 Position 类上添加查找器:

class Position < ActiveRecord::Base
  belongs_to :committee
  belongs_to :member

  attr_accessible :description

  scope :find_all_by_first_name, lambda do |name|
    joins(:member).where("members.first_name = ?", name)
  end
end

这应该允许您执行以下操作:

peters_description = committee.positions.find_all_by_first_name('Peter').first.description

You could add the finder on the Position class:

class Position < ActiveRecord::Base
  belongs_to :committee
  belongs_to :member

  attr_accessible :description

  scope :find_all_by_first_name, lambda do |name|
    joins(:member).where("members.first_name = ?", name)
  end
end

This should allow you to do:

peters_description = committee.positions.find_all_by_first_name('Peter').first.description

在has_many中通过有没有办法直接引用连接表?

为了进一步阐述我之前的评论,

我的建议是查看 DevXpress XtraChart 的在线演示(基本上可以在任何地方使用:WinForms、WebForms、SL、WPF、ASP.NET MVC...)。

如果您觉得它满足您的所有需求,您可以购买它,我使用了它,并且我对它以及整个 DevXpress 产品套件非常满意。

Telerik 版本的图表类型似乎少得多,尤其是在 MVC 实现中。

SoftwareFX 的 ChartFX 是最完整、最强大的产品,是该公司多年投资和开发的成果,它的定位远远高于其他产品。

to further elaborate my previous comment above,

my suggestion is to check the online demo of DevXpress XtraChart (works basically everywhere: WinForms, WebForms, SL, WPF, ASP.NET MVC...).

if you feel it satisfies all your needs you could go for it, I used it and I am very happy with it and with the whole DevXpress product suite.

Telerik version seems to have much less chart types, especially in the MVC implementation.

ChartFX of SoftwareFX is the most complete and powerful, result of years of investment and development from that company and it locates itself way above all the others.

我认为 Makefile 正在尝试在当前目录中查找文件 gorilla.googlecode.com/hg/gorilla/context 。另外,为什么要在 make 文件中指定它而不是从源中导入它?

I think the Makefile is trying to find the file gorilla.googlecode.com/hg/gorilla/context in the current directory. Also, why would you want to specify it in a make file as opposed to importing it from within the Source?

请检查几件事

  1. 请确保在使用完客户端套接字后已将其关闭。
  2. 创建套接字时,指定适当的超时。

Please check couple of things

  1. Please make sure you have closed the client socket after you have finished using it.
  2. When you create a socket, specify a proper timeout.

您是否尝试过减少每次运行要索引的项目数量?在我这样做之前我也遇到了同样的问题。

转到“搜索设置”页面,并将每次 cron 运行要索引的项目数更改为 10。然后运行 ​​cron 并查看您得到的结果。您可能需要跑几次才能赶上,但之后就应该没问题了。

Have you tried to lower the number of items to index per run? I had the same issue till I did that.

Goto the Search Settings page and change the number of items to index per cron run to 10. Then run cron and see what you get. You may have to run a few times to catch up, but then you should be fine.

Facebook 阻止您通过 iframe(或任何框架)直接链接到实际网站。这是因为任何将 Facebook 放入 iframe(或任何框架)的网站都可以使用 JavaScript 访问 Facebook 页面的元素,包括用户名和密码字段。

这是没有办法解决的。它内置于浏览器本身中,用于在请求标头中发送一些信息,表明正在请求将其放入框架中。

Gmail 和其他几个网站也这样做。

基本上。你不能陷害 Facebook。

Facebook prevents you from linking directly to the actual site via an iframe (or any frame). This is because any site putting Facebook in an iframe (or any frame) could use JavaScript to access elements of the Facebook page, including the username and password fields.

There is no way around this. It is built in to the browsers themselves to send some information along in the request header that says it is being requested to be put in frame.

Gmail and several other sites do this as well.

Basically. You can not frame Facebook.

无法在 iFrame 中在 Facebook 上进行身份验证

我认为没有更快的方法。

我认为您不应该担心表达式的性能。

执行 (SELECT, UPDATE, ...) 语句所涉及的所有其他内容很可能比日期/时间计算昂贵得多(例如检索行的 I/O)。

I don't think there is any quicker method.

And I don't think you should be worried about the performance of the expression.

Everything else that is involved in executing your (SELECT, UPDATE, ...) statement is most probably a lot more expensive (e.g. the I/O to retrieve rows) than that date/time calculation.

onCreate(Bundle savedInstanceState){    
TabHost tabHost = ...;
    tabHost.setCurrentTab(1);//index of second tab
...
}

或者作为一个选项 - 将内容从第二个选项卡移动到第一个选项卡。

onCreate(Bundle savedInstanceState){    
TabHost tabHost = ...;
    tabHost.setCurrentTab(1);//index of second tab
...
}

Or as an option - move a content from second tab to first one.
