这是由语言定义的吗？是否有定义的最大值？在不同的浏览器中是不同的？

是否有某些全局状态我可以访问当前运行的测试名称？

我有测试将文件输出到一个目录并读回来.我希望每个测试创建一个目录,然后清理它自己,我不想推它(我是必须使它独特,然后确保每个测试保持其独特性; ew).我可以使用GUID,但我希望帮助方法能够假设"这是应该存储测试文件的地方",而不必将GUID推送到它们.再次,这个地方的全球状态.

基本上,我想要一个电话TestRunner.Current.CurrentTest.Name.这样的事情存在吗？

我有一个UIImageView显示比更宽更高的图像UIImageView.我想使用动画在视图中平移图像(这样平底锅很漂亮和平滑).

在我看来,我应该能够仅仅调整bounds.origin的UIImageView,和图像应移动(因为形象应与作为视图中绘制它的起源,对不对？),但似乎并没有工作.的bounds.origin变化,但图像绘制在相同的位置.

几乎可以工作的是改变contentsRect视图的层.但这开始是一个单位正方形,即使图像的可视区域不是整个图像.所以我不确定如何检测到图像的远边被拉入可视区域(我需要避免,因为它通过将边缘拉伸到无限远来显示,看起来很好,低于标准杆).

我的视图目前已通过Interface Builder contentsGravity设置kCAGravityTopLeft,如果这有所不同(是否导致图像移动？).但是,没有其他选择似乎更好.

更新:要清楚,我想在视图内移动图像,同时保持视图在同一点.

找出在真实浏览器中选择的内容非常简单:

var range = {
  start: textbox.selectionStart,
  end: textbox.selectionEnd
}

但IE像往常一样,不明白.什么是最好的跨浏览器方式？

我们目前正在将我们的Rails应用程序升级到Rails 4.在3.2中,我们的Cucumber(1.3.17)测试运行良好(如果可悲的缓慢),与Capybara(2.4.4),Poltergeist(1.5.1)和PhantomJS(1.9. 8)引擎盖下.

但是在4.0.12和4.1.8中,我们stream closed (IOError)在运行中得到一个随机点:

我有一个DTrace探针捕获函数的调用,函数的一个参数是a CFStringRef.这是一个私有结构,它包含一个指向unicode字符串的指针.但CFStringRef它本身并不是一个char*普通的DTrace方法,就像copyinstr()返回一样?cp?,这并不是很有用.

那么如何在DTrace动作中打印出字符串呢？

我有一个使用jQuery和大量动态生成内容的项目.click左上角元素上有一个处理程序 - "主动"得分 - 它在桌面Safari上工作正常但在Mobile Safari上根本没有调用; 灰色覆盖层永远不会出现,也不会采取任何措施.与点击区域(右侧172)的点击处理程序和状态(底部的"添加状态效果";确认;它出现在肖像上)的情况相同:所有工作都在桌面上但不是移动Safari.

我已将代码缩减为以下内容:

<html>
  <head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
    <script>
      $(function() {
        $('#dynamic').click(function() {alert("works")});
        $('#dynamic-with-onclick').click(function() {alert("works")});
        $('#dynamic-with-dynamic-onclick').click(function() {alert("works")}).attr('onclick', '');
      })
    </script>
  </head>
  <body>
    <ul>
      <li id='static' onclick='alert("works")'>If there's an onclick it's called</li>
      <li id='dynamic'>And if there's no onclick the iPad won't see other click events</li>
      <li id='dynamic-with-onclick' onclick=''>But if there is one all events are called</li>
      <li id='dynamic-with-dynamic-onclick'>And if we add one everything works</li>
    </ul>
  </body>
</html>

更新

现在看起来比我10个月前最初提出这个问题要简单得多; 使用现代Mobile Safari,所有点击处理程序都会正常注册.所以,出去,只是使用$(...).click(function() {})!
