我很好奇如何让Carousel成为文本滑过的单个静态图像,而不是一堆随文本变化的图像.

IE:当点击下一个幻灯片按钮时,它只是移动的文本,图像保持不变并且不移动.

<div id="myCarousel" class="carousel slide" data-ride="carousel">
          <!-- Indicators -->
          <ol class="carousel-indicators">
            <li data-target="#myCarousel" data-slide-to="0" class="active"></li>
            <li data-target="#myCarousel" data-slide-to="1"></li>
            <li data-target="#myCarousel" data-slide-to="2"></li>
          </ol>
          <div class="carousel-inner">
            <div class="item active">
              <img src="data:image/gif;base64,R0lGODlhAQABAIAAAHd3dwAAACH5BAAAAAAALAAAAAABAAEAAAICRAEAOw==" alt="First slide">
              <div class="container">
                <div class="carousel-caption">
                  <h1>Example headline.</h1>
                  <p>Note: If you're viewing this page via a <code>file://</code> URL, the "next" and "previous" Glyphicon buttons on the left and right might not load/display properly due to web browser security rules.</p>
                  <p><a class="btn btn-lg btn-primary" href="#" role="button">Sign up today</a></p>
                </div>
              </div>
            </div> …

我将如何在 React JS 中查找上传文件的大小？

我正在尝试获取下面的代码,以允许我在控制台中输入Accept或Reject; 但是在线"if var userData = fileHandle.availableData {"我收到错误

条件绑定中的绑定值必须是可选类型

func input() -> String {
   var fileHandle = NSFileHandle.fileHandleWithStandardInput()
   println("Accept or Reject")
   if var userData = fileHandle.availableData{
       var userString = NSString(data: userData, encoding: NSUTF8StringEncoding)
       println("You have been \(userString)")
   }
}

input()

我正在尝试每秒刷新一次标签,以便倒计时更新,遇到一些麻烦.对于noob问题,我对C#道歉非常陌生.

private void Form1_Load(object sender, EventArgs e)
{
    bool ephCD = true;
    int ephHours = (DateTime.Today.AddDays(1) - DateTime.Now).Hours;
    int ephMinu = (DateTime.Today.AddDays(1) - DateTime.Now).Minutes;
    int ephSecs = (DateTime.Today.AddDays(1) - DateTime.Now).Seconds;

    label1.Text = ephHours.ToString() + ":" + ephMinu.ToString() + ":" + ephSecs.ToString();

    while (ephCD == true)
    {
        label1.Refresh();
    }
}

启动时,程序甚至不会出现.

为什么程序没有出现？
