我正在尝试在单击按钮时更新按钮的文本.我有许多具有相同类但没有id的按钮.为什么这不起作用？

<input type="button" class="add-button" value="Default" />
<input type="button" class="add-button" value="Default" />
<input type="button" class="add-button" value="Default" />
<input type="button" class="add-button" value="Default" />

$(document).ready(function() {
    $('.add-button').click(function() {
        alert('clicked');
        $(this).html('Changed');
    });
});?

警报已触发,但按钮未更改.

我试图将日期字符串解析为java.util.Date使用java.text.SimpleDateFormat; 但是,生成的格式化日期是错误的.

这是一个显示问题的测试用例:

@Test
public void testSimpleDateFormat() throws Exception {
    String dateString = "2016-03-03 11:50:39.5960000";
    SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSSSSS");
    Date date = format.parse(dateString);

    assertEquals(dateString, format.format(date));
}

这导致以下失败:

org.junit.ComparisonFailure: 
Expected :2016-03-03 11:50:39.5960000
Actual   :2016-03-03 13:29:59.0000000

日期是正确的,但小时,分钟,秒和毫秒都是错误的.为什么java.text.SimpleDateFormat搞砸我约会的时间？

我试图模拟我的存储库的Get()方法返回一个对象,以伪造该对象的更新,但我的设置不起作用:

这是我的测试:

[Test]
public void TestUploadDealSummaryReportUploadedExistingUpdatesSuccessfully()
{
    var dealSummary = new DealSummary {FileName = "Test"};
    _mockRepository.Setup(r => r.Get(x => x.FileName == dealSummary.FileName))
        .Returns(new DealSummary {FileName = "Test"}); //not working for some reason...

    var reportUploader = new ReportUploader(_mockUnitOfWork.Object, _mockRepository.Object);
    reportUploader.UploadDealSummaryReport(dealSummary, "", "");

    _mockRepository.Verify(r => r.Update(dealSummary));
    _mockUnitOfWork.Verify(uow => uow.Save());
}

以下是正在测试的方法:

public void UploadDealSummaryReport(DealSummary dealSummary, string uploadedBy, string comments)
{
    dealSummary.UploadedBy = uploadedBy;
    dealSummary.Comments = comments;

    // method should be mocked to return a deal summary but returns null
    var existingDealSummary = …

我正在研究一个类的项目,可能是我们必须实现一个简单调度程序的WORST指令..虽然C编程不是课程的先决条件,这是调度程序的语言,我不一定是C语言程序员..

无论如何,我试图通过打印任务来调试它,以便我可以通过程序跟踪它,但我不断收到以下编译时错误:

schedule.c:61:48:error:解除引用不完整类型的指针

这是task_struct定义:

struct task_struct
{
    struct thread_info *thread_info;        
    int prio, static_prio, normal_prio;     
    unsigned long sleep_avg;            
    unsigned long long last_ran;            
    unsigned long long timestamp;           
    unsigned long long sched_time;          
    unsigned int time_slice, first_time_slice;  
    struct list_head run_list;          
    struct sched_array *array;          
    enum sleep_type sleep_type;         
    int need_reschedule;                
};

我试图在里面调试的功能:

void initschedule(struct runqueue *newrq, struct task_struct *seedTask)
{
printf("Inside initschedule()\n");

printf("%s - TEST \n", (seedTask)->thread_info->processName); //causes compiler error

/* initialize runqueue and current task */
rq = newrq;
current = NULL;

/* …
