只需检查calendar.get(Calendar.AM_PM) == Calendar.AM

Calendar now = Calendar.getInstance();
if(now.get(Calendar.AM_PM) == Calendar.AM){
   // AM
}else{
   // PM
}

Simply check calendar.get(Calendar.AM_PM) == Calendar.AM

Calendar now = Calendar.getInstance();
if(now.get(Calendar.AM_PM) == Calendar.AM){
   // AM
}else{
   // PM
}

使用日历确定上午或下午日期

您是否希望此消息仍然显示,然后将其重定向到其他地方?或者您是否想一起丢弃此消息并将他们定向到具有类似消息的不同页面?

您可以按原样显示该页面,并包含另一个回显以触发重定向:

echo "<META HTTP-EQUIV=\"REFRESH\" CONTENT=\"2;URL=/someotherpage.php\">";

Do you want this message to still show and THEN redirect them somewhere else? Or do you want to discard this message all together and direct them to a different page that will have a similar message?

You could show that page as is, and include another echo to trigger a redirect:

echo "<META HTTP-EQUIV=\"REFRESH\" CONTENT=\"2;URL=/someotherpage.php\">";

表单成功后php重定向

我假设您已使用 cookie 来存储他们的登录详细信息,以便他们在下次访问您的 Web 应用程序时可以自动登录。作为密码更改功能的一部分,您需要删除 cookie(迫使他们在下次访问时使用新的详细信息再次登录 - 此登录应该为将来的访问创建 cookie)或修改 cookie 以存储更新的登录详细信息(以便它们继续自动登录到您的 Web 应用程序)。

I'm assuming that you've used a cookie to store their login details, so that you can automatically log them in the next time they visit your web application. As part of your password change functionality, you'll want to either remove the cookie (forcing them to login again next time they visit, using their new details - this login should then create the cookie for future visits) or modify the cookie to store the updated login details (so that they continue to be logged into your web application automatically).

在 Unix 上,除非写入应用程序出现问题,否则文件不会被锁定,您将能够从中读取内容。

当然,读者必须准备好处理不完整的文件(请记住,作者一方可能会发生 I/O 缓冲)。

如果这是行不通的,您将不得不考虑一些方案来同步写入器和读取器,例如:

  • 显式锁定文件;
  • 将数据写入临时位置,并且仅在文件完成时将其移动到最终位置(如果源和目标位于同一文件系统上,则移动操作可以原子方式完成)。

On Unix, unless the writing application goes out of its way, the file won't be locked and you'll be able to read from it.

The reader will, of course, have to be prepared to deal with an incomplete file (bearing in mind that there may be I/O buffering happening on the writer's side).

If that's a non-starter, you'll have to think of some scheme to synchronize the writer and the reader, for example:

  • explicitly lock the file;
  • write the data to a temporary location and only move it into its final place when the file is complete (the move operation can be done atomically, provided both the source and the destination reside on the same file system).

Python 会在文件写入完成之前打开文件吗?

CSS 规范 中定义了多种颜色因此任何兼容 CSS 的浏览器都会正确显示您的颜色。

There are a number of colors that are defined within the CSS specification so any CSS compliant browser will display your color correctly.

背景颜色:白色 - 好的还是应该使用十六进制?

无论是后台线程还是 UI 线程,网络活动都会执行相同的操作。问题可能是报告进度或记录活动等的任何其他代码。这可能会阻塞线程。

Network activity performs same whether it's background thread or UI thread. The problem can be any other code of reporting progress or logging activity etc. That may block the thread.

你可以循环遍历你的数组,像这样(未经测试)

// $resultset is you multidimensional array

$optimised = Array();  // good habit to initialise before usage.

foreach($resultset as $key => $value){
   $optimised[] = $value['name'];
}

祝你好运!

You could loop through your array, something like this ( not tested )

// $resultset is you multidimensional array

$optimised = Array();  // good habit to initialise before usage.

foreach($resultset as $key => $value){
   $optimised[] = $value['name'];
}

Good-luck!

使用 PHP 修改查询结果以返回更可用的数组

我想问的第一件事是如何创建手风琴元素?您使用 AjaxHelper 类还是仅使用 jQuery 方法?

提交表单后,您将使用 jQuery UI 语法来销毁并重新创建新的折叠面板。但要使用 Helper 创建它,您必须使用 $ajax 对象及其函数。有没有办法让 AjaxHelper 更改 UI 定义并以某种方式包装它?

First thing I want to ask is how do you create the accordion element? Do you use the AjaxHelper class or simply the jQuery method?

After you submit the form, you are using jQuery UI syntax to destroy and recreate new accordion. But to create it using the Helper, you would have to use the $ajax object and it's functions. Is there a way, that AjaxHelper changes the UI definition and wraps it somehow?

几乎满足您的所有要求:)

#include <stdio.h>

int mult7(int i)
{
    int res;
    __asm__("imull  $7, %1, %0" : "=r" (res) : "r" (i));
    return res;
}

int main()
{
    printf("%d", mult7(12)); //output: 84
    return 0;
}

Meets almost all your requirements :)

#include <stdio.h>

int mult7(int i)
{
    int res;
    __asm__("imull  $7, %1, %0" : "=r" (res) : "r" (i));
    return res;
}

int main()
{
    printf("%d", mult7(12)); //output: 84
    return 0;
}

List<Integer> numbers = new ArrayList<Integer>(){{ add(1); add(2); }};

我真的不推荐这种方法,因为它无缘无故地创建了一个(匿名)类。

使用:

List<Integer> numbers = Arrays.asList(1, 2);

List<Integer> numbers = new ArrayList<Integer>(Arrays.asList(1, 2));

对于 2 个级别,您可以使用:

List<List<Integer>> numbers = Arrays.asList(Arrays.asList(1, 2), Arrays.asList(2,3,4));

通过静态导入,您甚至可以将其减少为这样,如果您确实想要:

List<List<Integer>> numbers = asList(asList(1, 2), asList(2,3,4));
List<Integer> numbers = new ArrayList<Integer>(){{ add(1); add(2); }};

I don't really recommend this approach, as it creates an (anonymous) class for no good reason.

Use either:

List<Integer> numbers = Arrays.asList(1, 2);

or

List<Integer> numbers = new ArrayList<Integer>(Arrays.asList(1, 2));

For 2 levels, you can use:

List<List<Integer>> numbers = Arrays.asList(Arrays.asList(1, 2), Arrays.asList(2,3,4));

With a static import you could even reduce it to this, if you really want to:

List<List<Integer>> numbers = asList(asList(1, 2), asList(2,3,4));

这就是线程和共享变量的问题,如果不同步,你永远不知道什么时候会崩溃。首先,您必须找出为什么会有更多线程访问您的代码,如果您无法“删除”该行为,则必须使用锁或其他同步机制来同步对对象中共享的所有变量的访问。 (请小心中继,以免出现任何死锁)。

这里的重点是。如果您无法使代码在单步中运行,则必须同步对对象中变量的访问,这样事情就不会崩溃。

That is the problem with threads and shared variables, if you don't synchronize you never know when things crash. First off you have to find why you get more threads accessing your code, If you can not "remove" the behavior you will have to synchronize the access to all the variables that are shared in you object using locks or some other synchronizing mechanisms. (Be relay careful that you do not get any deadlocks doing that).

The point here is. If you are not able to make the code run in a single tread, you have to synchronize the access to the variables in the object so things will not crash.

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.
