目标 我试图做的是捕获“加载资源失败”错误并将其放入警报窗口 问题 我正在尝试捕捉一段不存在的视频。Try-catch未捕获异常 背景 我正在尝试播放一系列视频，当前一个视频结束时，我继续播放下一个视频。问题是阵列中的每个元素并不总是有视频。我已经试着将try catch放置在play函数周围。我还尝试将PlayArray（）函数的全部内容放在try中，但没有成功，我还尝试将try放在PlayArray函数调用自身的位置。 我没有机会尝试捕捉，捕捉异常 HTMLHtml 尝试在递归函数中捕获不工作,html,recursion,html5-video,try-catch,Html,Recursion,Html5 Video,Try Catch,目标 我试图做的是捕获“加载资源失败”错误并将其放入警报窗口 问题 我正在尝试捕捉一段不存在的视频。Try-catch未捕获异常 背景 我正在尝试播放一系列视频，当前一个视频结束时，我继续播放下一个视频。问题是阵列中的每个元素并不总是有视频。我已经试着将try catch放置在play函数周围。我还尝试将PlayArray（）函数的全部内容放在try中，但没有成功，我还尝试将try放在PlayArray函数调用自身的位置。 我没有机会尝试捕捉，捕捉异常 HTML <!doctype htm
