暂停多个HTML5视频 [英] Pause Multiple HTML5 Videos

问题描述

我在幻灯片中有多个HTML5视频，位于 http://ghostpool.com/wordpress/phideo当我点击任何滑块按钮时，使用以下 onclick 功能暂停第一个视频。

I have multiple HTML5 videos in a slider at http://ghostpool.com/wordpress/phideo and when I click on any of the slider buttons the first video is paused using the following onclick function.

<a href="#" onclick="pausePlayer();">LINK</a>


var htmlPlayer = document.getElementsByTagName('video')[0];

function pausePlayer() {
  htmlPlayer.pause();
}

但是，单击滑块按钮时，第二个视频不会暂停。我假设上面的Javascript不适用于多个视频？

However the second video does not pause when the slider buttons are clicked. I assume the Javascript above does not work with multiple videos?

编辑：此外，如果点击视频元素本身我想切换一个播放和暂停功能。我正在使用此代码，但它会立即播放和停止所有视频。我假设我没有正确循环播放：

Additionally, if clicking on the video element itself I want to toggle a play and pause function. I"m using this code, but it plays and stops all videos at once. I assume I'm not looping it correctly:

function togglePlayer() {

for(var i = 0; i < htmlPlayer.length; i++){

    if ( htmlPlayer[i].paused || htmlPlayer[i].ended ) {    

        if ( htmlPlayer[i].ended ) { htmlPlayer[i].currentTime = 0; }
        htmlPlayer[i].play();

      }  else { 

      htmlPlayer[i].pause();

    }

}
}

推荐答案

这显然不起作用，因为你只是得到了由 getElementsByTagName 返回的数组中的第一个元素。 [0] 部分访问数组中的第一个元素。我想做的是用循环迭代所有这些，如下所示：

This obviously won't work because you are only getting the first element in the array returned by getElementsByTagName. The [0] part accesses the first element in the array. What you would want to do is to iterate through all of them with a loop, like this:

var htmlPlayer = document.getElementsByTagName('video');

function pausePlayer() {
  for(var i = 0; i < htmlPlayer.length; i++){
    htmlPlayer[i].pause();
  }
}

修改

关于您的第二个问题 - 您可以尝试使用此代码：

Regarding your second question - You can try using this instead:

for(var i = 0; i < htmlPlayer.length; i++){
    htmlPlayer[i].onclick = function() {
        if ( this.paused || this.ended ) {    
            if ( this.ended ) { this.currentTime = 0; }
            this.play();
        }  else { 
            this.pause();
        }
    }
}

事件处理程序中的这个应该引用调用它的元素。

this in a event handler should refer to the element that called it.
